How does solar self-consumption work in Luxembourg, and how can you optimise it?
By Yacine Sahnoune, founder of renov.lu
Since 2022, self-consumption has become the dominant operating model for residential solar PV in Luxembourg. It means using the electricity your panels produce directly, exporting the surplus to the grid, and maximising the savings on your electricity bill. Without a battery, a Luxembourg household self-consumes on average 25–45% of its production; with a battery, this rate rises to 65–80%. All within a very favourable tax framework: feed-in income is fully exempt from income tax for installations ≤ 30 kWp. Since 4 January 2026, self-consumption has also been a mandatory condition for the Klimabonus solar panel grant. This page explains everything: how it works technically, regulatory thresholds, ways to optimise it, tax rules and collective self-consumption.
- Self-consumption rate: without a battery, a Luxembourg household uses on average 25–45% of its solar production; with a 6–10 kWh battery, 65–80%.
- Value of a kWh: each self-consumed kWh saves buying grid electricity at around €0.21–0.28/kWh, whereas exported surplus is generally bought back at €0.04–0.10/kWh.
- Klimabonus: since 4 January 2026, the solar PV grant (up to €10,000) requires self-consumption and waiving the guaranteed feed-in tariff of €0.1333/kWh over 15 years (up to 10 kWp, first feed-in in 2026).
- Battery: Klimabonus of up to €2,250 for 9 kWh of capacity; VAT is 3% on installed panels, but budget for 17% on the battery to be safe.
- Tax: for installations of up to 30 kWp, feed-in income is exempt from income tax and does not have to be declared.
- Creos connection: apply on myCreos; a single meter is enough if the inverters are ≤ 30 kVA and you have a variable buy-back contract; allow 4 to 8 weeks in total.

What is solar self-consumption in Luxembourg?
Solar (photovoltaic) self-consumption means using the electricity produced by your own solar panels yourself, directly and in real time. When your panels produce more than you are using at that moment, the surplus is automatically fed into the public grid and bought by your energy supplier. When your consumption exceeds production (at night, in cloudy weather), you import electricity from the grid as usual.
Self-consumption has only been legally possible in Luxembourg since late 2021. Before then, owners of solar panels had no choice but to feed their entire production into the grid, paid at the guaranteed feed-in tariff. Opening the market to self-consumption changed everything: it is now the most common model for new residential installations, and it is a mandatory condition for the Klimabonus 2026 and the pre-financing scheme. For full details of the support available, see our page on solar panel grants and subsidies in Luxembourg.
In Luxembourg, a self-consumer is also known as a « prosumer » (producer + consumer). The household produces, consumes, possibly stores (with a home battery) and sells its surplus. This model is made possible by a bidirectional smart meter managed by Creos, which separately measures, every quarter of an hour, the energy imported from the grid and the energy exported to it.
These two indicators are often confused. The self-consumption rate measures the share of your solar production that you use yourself (e.g. 40% of your production is self-consumed). The self-sufficiency rate measures the share of your total electricity needs covered by your panels (e.g. your panels cover 35% of your annual consumption). The two rates move in opposite directions depending on the size of your system: the larger it is, the more you export (lower self-consumption rate), but the more self-sufficient you become (higher self-sufficiency rate).
Self-consumption vs full feed-in: which to choose in 2026?
For a long time, full feed-in with a guaranteed tariff was the most profitable option in Luxembourg, thanks to very generous feed-in tariffs (€0.1506/kWh in 2022, €0.1374/kWh in 2025). But the picture changed fundamentally in 2026:
| Criterion | Self-consumption (+ surplus export) | Full feed-in (guaranteed tariff) |
|---|---|---|
| Klimabonus 2026 eligibility | ✅ Yes — mandatory condition | ❌ No — incompatible with the new scheme |
| Pre-financing (third-party payment) | ✅ Yes | ❌ No — excluded from the scheme |
| Value of each kWh produced | ≈ €0.21–0.28/kWh (electricity you no longer buy at the grid price) | €0.1333/kWh (2026 guaranteed feed-in tariff, ≤ 10 kWp) |
| Guaranteed payment period | No guarantee — variable buy-back rate | 15 years at a fixed rate |
| Tax (≤ 30 kWp) | Fully exempt from income tax | Fully exempt from income tax |
| Maximum grant | Up to €10,000 (Klimabonus 2026) | None (the guaranteed tariff cannot be combined with the Klimabonus) |
| Typical payback period | 7–10 years (with battery: 8–12 years) | 10–15 years (depending on tariff and installation) |
For a new installation, the Klimabonus route (self-consumption, grant of up to €10,000) usually comes out ahead, because a self-consumed kWh (electricity you no longer buy at the grid price, ≈ €0.21–0.28) is worth much more than the guaranteed feed-in tariff (€0.1333/kWh in 2026 up to 10 kWp). This is not always the case, though: above roughly ten kWp with little self-consumption, the guaranteed tariff can pay more. Owners of existing installations on a guaranteed contract are better off keeping it until the 15-year term ends. To estimate your solar panel return on investment under both scenarios, use our simulator.
How it works: meter, inverter and grid connection
To self-consume in Luxembourg, your installation must be connected to the grid and fitted with the right technical components. Here is how energy flows through a self-consumption system.
Solar panels produce direct current (DC) in proportion to the amount of sunlight. The inverter converts this into 230 V alternating current (AC) compatible with your home’s electrical system. The energy produced first powers your home directly (self-consumption first): lighting, household appliances, water heater, heat pump, etc. Only the surplus, once every appliance has been supplied, goes into the grid.
This surplus is recorded to the quarter-hour by the bidirectional smart meter installed by Creos. The meter separately measures:
- The energy imported from the grid, which you pay your supplier for
- The energy exported to the grid, which your supplier buys from you at a variable rate
Since the Grand-Ducal Regulation of 30 June 2023, a self-consumption PV installation can be connected without a separate generation meter if the following conditions are met: inverter capacity ≤ 30 kVA, low-voltage connection on a single smart meter, and a variable buy-back contract with a supplier. This simplification has considerably reduced the cost and complexity of connecting small residential installations.
Unlike full feed-in, where more capacity always meant more income, with self-consumption the optimal system size depends on your consumption. An oversized system produces a lot of surplus sold at a low price; an undersized one does not improve your self-sufficiency enough. The general rule of thumb in Luxembourg: 1 kWp per 1,000 kWh of annual consumption is a starting point, to be fine-tuned to your profile and budget. See our complete guide to solar PV sizing in kWp.
Self-consumption rates: real-world figures for Luxembourg
The data available for Luxembourg (average yield of 850–950 kWh/kWp per year depending on orientation, residential consumption profiles) give the following orders of magnitude. These figures are indicative and depend heavily on your consumption profile, how much time you spend at home and your equipment:
| Configuration | Self-consumption rate | Self-sufficiency rate |
|---|---|---|
| Panels only — household out during the day | 20–30% | 20–35% |
| Panels only — someone at home during the day (working from home) | 30–45% | 30–45% |
| Panels + solar diverter (water heater) | 35–55% | 35–50% |
| Panels + battery (6–10 kWh) | 65–80% | 50–70% |
| Panels + battery + electric vehicle charged during the day | 70–85% | 60–80% |
| Panels + battery + heat pump + EV | 75–90% | 65–85% |
Each self-consumed kWh is worth roughly 2 to 7 times more than an exported kWh at the variable buy-back rate. In 2026 in Luxembourg, grid electricity costs around €0.21–0.28/kWh all-in, while the variable buy-back rate for surplus power is generally between €0.04 and €0.10/kWh. That is why the winning strategy is always to increase direct self-consumption before trying to get more value from your exports.
6 ways to maximise your solar self-consumption in Luxembourg
Here are the most effective strategies, ranked by ease of implementation and measurable impact on your self-consumption rate:
Schedule energy-hungry appliances during production hours
Washing machine, dishwasher, tumble dryer, electric water heater: every appliance set to run between 9am and 4pm (rather than at night or in the evening) means 1–3 extra kWh self-consumed per day. Most modern household appliances have a built-in delay timer. It is the quickest win, with no additional investment at all. In terms of impact: +5 to +15 percentage points on your self-consumption rate, depending on your appliances.
Install a solar diverter (also called a « solar router » or « solar booster »)
This small device (€150–300) detects surplus power before it is exported and automatically diverts it to your hot water cylinder or electric water heater. It works continuously with no manual intervention. For a household using 3–5 kWh of hot water per day, it is often the most cost-effective option available: payback in 2–4 years, and +5 to +15% on your self-consumption rate. Compatible with all existing cylinders fitted with an electric immersion heater.
Charge your electric car during production hours
An electric car on charge draws 7–11 kW depending on the charging mode — often more than your panels’ entire output. Being able to charge partly between 9am and 4pm can push your self-consumption rate up by 15–30 percentage points. A charging point with solar control (an EVSE with « solar mode ») fully automates this: it adjusts the charging power to the surplus available, and stops charging altogether if the surplus drops below the minimum.
Install a home battery
This is the lever with the biggest impact on your self-consumption rate: it stores the daytime surplus for use at night, turning a day of surplus into a self-sufficient evening. A 6–10 kWh battery alone can take your self-consumption rate from 35% to 70%. See the dedicated section below for sizing and the Klimabonus battery grant.
Pair your solar system with your heat pump
If you already have a heat pump (or are planning to install one), smart integration with your solar panels lets it run its heating or cooling cycles primarily during production hours. This pairing can easily add 5–20% to your self-consumption rate, depending on the climate, the size of the systems and the control strategy. Reversible heat pumps (cooling in summer, heating in winter) allow year-round pairing.
Choose an east-west layout rather than due south
Counter-intuitive but effective: an array split across east- and west-facing roof slopes produces 10–15% less energy in total than a due-south array of the same capacity, but it produces for longer over the day (from 7.30am to 8.30pm in summer, versus 9am–5pm for due south). This « flatter » production profile matches residential consumption patterns better and can raise the self-consumption rate by 5–10% compared with due south. Particularly worth considering if you work from home in the morning or charge an EV in the evening.
The key role of battery storage in self-consumption
A home battery is the component that turns an ordinary solar installation into a genuine, self-sufficient home power station. By storing the surplus produced around midday (when production exceeds consumption), it lets you use solar energy in the evening and at night — times when production is zero but consumption is often high (cooking, TV, lighting, phone charging, etc.).
In Luxembourg in 2026, the most common residential batteries have a capacity of 5–15 kWh, costing roughly €700–1,100 per kWh of capacity, installation included (for example €3,500–5,500 for 5 kWh). The battery is subsidised separately under the Klimabonus 2026: up to €2,250 for 9 kWh of capacity, on a tapering formula (see the exact amounts on guichet.public.lu).
Without a battery
Self-consumption rate: 25–45%
Self-sufficiency rate: 25–45%
Unused daytime surplus is exported at a low rate.
Lower investment — faster payback.
With a battery (6–10 kWh)
Self-consumption rate: 65–80%
Self-sufficiency rate: 50–70%
Surplus is stored for night-time use.
Higher investment — payback in 8–12 years.
Practical sizing rule: in Luxembourg, the commonly recommended rule of thumb is about 1 kWh of battery capacity per kWp of solar PV. A 6 kWp system is well matched with a 6 kWh battery. Beyond 10–12 kWh of battery capacity, the extra self-consumption gains fall off significantly, unless you have an electric vehicle or a particularly power-hungry heat pump. You can install the battery at the same time as the panels or later — both approaches work.
In Luxembourg, the super-reduced 3% VAT rate applies to solar panels, mounting rails, accessories and their installation — but the rate for storage batteries is not officially specified: to be safe, budget for 17% and have it confirmed by the AED (the VAT authority). This point is essential for assessing the real cost of a system with storage. The Klimabonus battery grant (up to €2,250) partly offsets this difference.
Creos grid connection steps for self-consumption (myCreos)
To self-consume and export your surplus in Luxembourg, your installation must be officially connected to the Creos grid (or to the local grid operator, depending on your municipality: Sudstroum in Esch-sur-Alzette, Ville de Diekirch, Ville d’Ettelbruck). Below are the steps specific to Creos, which operates the electricity grid for the vast majority of Luxembourg households:
Connection request in your myCreos account
Create an account on myCreos.lu and submit your request for « self-consumption ». You can do this yourself or leave it to your approved electrician. For a standard new installation (≤ 30 kVA, low voltage), no complex technical file is required at the application stage — just basic information about your home and the planned capacity.
Preparatory work by an approved electrician
Your installer carries out the preparatory work: consumer unit with protective devices that meet Creos’s technical connection requirements (TAB), wiring and grid decoupling (interface) protection. The electrician must be approved in Luxembourg (listed in the craft trades register) — an unapproved electrician cannot sign the completion notification. The electrician submits the completion notification via the Smarty PRO app: as soon as the preparatory work is finished with the two-meter solution, and no later than 7 days after commissioning with the single-meter solution.
Signing a surplus buy-back contract
During the preparatory work, and therefore before commissioning, you must sign a variable buy-back contract with an electricity supplier of your choice (Enovos, Sudstroum, etc.) for the sale of your surplus electricity. Without this contract, you cannot export power and Creos cannot activate your connection in self-consumption mode. The buy-back rate is variable and indexed to energy market prices — so, unlike the guaranteed feed-in tariff, it is not fixed for the long term.
Commissioning and checks by Creos
With the single-meter solution (existing smart meter, inverters ≤ 30 kVA, variable buy-back contract), Creos authorises you to commission the installation once it has received all the required documents, then checks the completion notification and may carry out an on-site inspection. With the two-meter solution, Creos first checks the preparatory work; once it is approved, Creos installs the meter and commissions your installation within 30 days. If anything is non-compliant, you receive a correction report listing the points to fix, and a new appointment is scheduled.
The complete process — myCreos application + works + approval + connection — usually takes 4 to 8 weeks, depending on your installer’s schedule and Creos’s workload. Start at least 6 weeks before the date you want your system commissioned, especially in spring and summer (peak demand periods).
What happens to your surplus? Export and buy-back
With self-consumption, all the energy you produce but do not use immediately — whether in your appliances or in your battery if you have one — is automatically fed into the public grid. Your smart meter records these exports every quarter of an hour. Your energy supplier then pays you for this electricity at a variable rate.
What buy-back rate for surplus power in 2026? Unlike the full feed-in scheme with a guaranteed tariff (€0.1333/kWh for 15 years for a first feed-in in 2026, up to 10 kWp), new self-consumption installations receive a variable buy-back rate, indexed to wholesale electricity prices. Each supplier sets this rate in its contract and revises it periodically. It is generally between €0.04 and €0.10/kWh, depending on the period and the supplier — roughly 2 to 7 times less than the price you pay for electricity from the grid (€0.21–0.28/kWh).
This price gap is precisely why maximising direct self-consumption is always more profitable than trying to maximise exports. Every kWh exported at €0.06/kWh would have been worth €0.25/kWh if you had used it yourself.
Yes, for an installation connected to the public grid: you must have signed a buy-back contract with a supplier in order to export surplus power. Without this contract, Creos cannot activate your connection in self-consumption mode. You can, however, limit exports through your inverter settings (export power limited to 0%), which some owners do to keep things simple. But this means wasting the energy you produce instead of getting some value from it, even at a low price.
The national energy data platform LENEDA (leneda.lu) lets prosumers view their production, consumption and export data in real time, at quarter-hourly resolution. Creos also sends monthly energy statements to members of energy-sharing groups. Most recent inverters also come with their own monitoring app (SolarEdge, Fronius, SMA, Huawei, etc.).
Luxembourg tax rules for solar self-consumption
The tax treatment of solar self-consumption in Luxembourg is very favourable for private individuals. It is governed by Circular L.I.R. No. 14/2 of 5 June 2023 issued by the Direct Tax Administration (ACD), which clearly sets out how three scenarios are taxed.
The general principle for private individuals (≤ 30 kWp): Luxembourg’s Direct Tax Administration treats solar power generation by a private individual as an amateur (hobby) activity, which is not taken into account when determining taxable income. In practice: you do not declare your solar income and you have no specific tax obligations linked to feed-in or self-consumption.
| Case | Description | Tax treatment (≤ 30 kWp, private individual) |
|---|---|---|
| Case 1 | Full feed-in of all production | For ≤ 30 kWp: fully exempt. Above that: taxable commercial activity |
| Case 2 | Pure self-consumption, with no export to the grid | Not taxable (neither a commercial activity nor any other category of income). Expenses are not deductible; only the interest on a loan used to finance the installation is deductible as special expenses, within the statutory limits |
| Case 3 (the most common) | Self-consumption with surplus sold to the grid | For ≤ 30 kWp: feed-in income fully tax-exempt (same amateur-activity tolerance as in case 1); in return, installation-related expenses are not deductible |
What about VAT? As a private individual who is not registered for VAT, you do not charge VAT on the electricity you sell, and you cannot recover the VAT on your installation. You can voluntarily opt to register for VAT in order to recover the VAT on the investment (3% on the panels; for the battery, 17% to be safe, as the rate is not officially specified), but this entails annual VAT returns and is generally only worthwhile for large installations. Consult a tax adviser about your specific situation.
Feed-in income: exempt from income tax. VAT on panels and installation: 3%. VAT on the battery: 17% to be safe (rate not officially specified, to be confirmed with the AED; not recoverable for private individuals who are not VAT-registered). Nothing to declare to the Direct Tax Administration.
Collective self-consumption and energy communities in Luxembourg
Beyond individual self-consumption, Luxembourg offers two legal frameworks for sharing solar energy between several users. They are particularly relevant for co-owned apartment buildings, close neighbours, or groups wishing to pool a shared installation.
1. Collective self-consumption (AER-C)
This allows a group of producers and consumers connected to the same operator’s low-voltage grid (Creos) to share the energy produced without setting up a legal structure. The conditions vary depending on the set-up:
- Within the same building (residence): no limit on the number of members, no distance constraint between metering points
- Between neighbours (different buildings): maximum of 3 grid users, with a maximum distance of 100 metres between the furthest points
- Energy can be shared in proportion to consumption or according to a custom allocation key agreed between members
- Exemption from grid usage fees on shared electricity in both cases above
- How to apply: fill in the AER-C agreement available on the Creos website and send it to [email protected]
2. Renewable energy community (CER)
A more formal structure, which requires setting up an official legal entity notified to the ILR (Institut Luxembourgeois de Régulation, the national regulator). It allows energy to be shared over a wider area:
- Local CER: maximum distance of 300 metres between members — exemption from grid usage fees on shared electricity
- National CER: no geographical restriction, but no exemption from grid fees on shared energy
- Energy flows can be monitored via the LENEDA platform (leneda.lu) or weshareenergy.lu (the ILR platform dedicated to energy communities)
In a co-owned building (condominium), the decision to install shared solar panels must be taken at the general meeting. Once installed, the energy can be shared among participating co-owners through AER-C, with no limit on the number of members. The Klimabonus battery grant is available to co-ownerships if the installation’s capacity exceeds 1.5 kWp per participating private unit. Majorities and the managing agent’s file: votes and grants in a co-ownership.
Switching an older installation to self-consumption
If your solar panels were installed before 2022, you may still have a full feed-in contract with a guaranteed tariff running. Here is what you need to know before considering a switch to self-consumption:
Is it technically possible? Yes, Creos has accepted switch requests since late 2021. You apply via myCreos by selecting « I already produce energy and want to consume the energy I produce myself ». Your installer can help you with this. Your old meter will usually need to be replaced with a bidirectional meter, if this has not already been done.
Does it make financial sense? It needs to be worked out case by case, comparing:
- The remaining value of your guaranteed contract (tariff × kWh × years remaining)
- The potential gain from self-consumption (electricity you no longer buy, at ≈ €0.21–0.28/kWh × your estimated self-consumption rate)
As a general rule: if your guaranteed tariff is still high (€0.1506/kWh for 2022 installations) and you have several years left, it may be better to stay on full feed-in until the contract ends. If your tariff is low, or if you have just added power-hungry equipment (heat pump, EV), switching may pay off straight away.
Are there grants for older installations that switch? No. The Klimabonus 2026 and pre-financing only apply to new installations or extensions. However, if your original installation was commissioned more than 2 years ago, you can add new panels and receive the Klimabonus for that extension, provided the first feed-in date of the new section is at least 2 years after that of the original installation. See our guide to solar pre-financing in Luxembourg.
Terminating a guaranteed feed-in tariff contract before it expires may lead to contractual penalties, depending on the terms of your contract. Check the termination clauses with your energy supplier before taking any action. In some cases, it is better to wait for the contract to run its natural course than to pay penalties.
Frequently asked questions about solar self-consumption in Luxembourg
Is self-consumption mandatory to get the Klimabonus 2026?
Yes. Since 4 January 2026, the Klimabonus for solar panels has required self-consumption, with a waiver of the guaranteed feed-in tariff. The guaranteed tariff is still available for a new installation, but without the Klimabonus. Installations with a guaranteed feed-in tariff contract (15 years; €0.1333/kWh up to 10 kWp for a first feed-in in 2026) are not eligible for the new Klimabonus or the pre-financing scheme. The two schemes are mutually exclusive — an owner on an existing guaranteed-tariff contract cannot receive the Klimabonus 2026 for the same installation.
Can I self-consume without being connected to the Creos grid?
Technically, yes: an off-grid installation is possible in Luxembourg. But it is not recommended for a main residence, because solar production is low in winter (around 30 to 40 kWh per kWp per month from November to January, compared with about 130 kWh in summer, according to PVGIS), which would require a fossil-fuel backup generator. In addition, an off-grid installation qualifies for neither the Klimabonus nor pre-financing, and you cannot sell any surplus. Almost all residential installations in Luxembourg are grid-connected.
Do I have to declare my feed-in income to the Luxembourg tax authorities?
No, not for installations ≤ 30 kWp. Circular L.I.R. No. 14/2 of 5 June 2023 from Luxembourg’s Direct Tax Administration treats residential solar generation as a non-taxable amateur activity. You do not declare this income and you have no specific tax obligations linked to feed-in or self-consumption — no annual return, no VAT to collect.
What buy-back rate applies to surplus solar power in Luxembourg in 2026?
For new self-consumption installations, the buy-back rate is variable and indexed to wholesale electricity prices. It is not published as a fixed, guaranteed tariff — it changes with market conditions and is set in your buy-back contract with your supplier (Enovos, Sudstroum, etc.). In 2026, this rate is generally below €0.10/kWh, far less than the price of electricity bought from the grid (≈ €0.21–0.28/kWh). This is the main reason why maximising self-consumption is always more profitable than exporting.
How long does a Creos grid connection take for a new installation?
With the two-meter solution, once Creos has approved the preparatory work, the meter is installed and the system commissioned within 30 days; with the single-meter solution, Creos authorises commissioning once it has received the required documents. The whole process — myCreos application + electrician’s work + Creos connection — usually takes 4 to 8 weeks, depending on your installer’s schedule and Creos’s workload. In spring and summer (peak installation season), lead times can be longer: allow 6 to 10 weeks during these periods.
Can I share my solar power with my neighbour without setting up a company?
Yes, through collective self-consumption (AER-C). This scheme allows up to 3 neighbouring grid users (within 100 metres of each other) to share the energy produced without setting up any specific legal structure. You simply fill in the AER-C agreement available on the Creos website and send it to [email protected]. However, if you want to share over a wider area or with more than 3 members, you need a renewable energy community (CER), with a legal entity notified to the ILR.
Is my home battery eligible for 3% VAT?
That is not guaranteed. In Luxembourg, the super-reduced 3% VAT rate applies to solar panels, mounting rails, accessories and their installation, but the rate for storage batteries is not officially specified: to be safe, budget for 17% and have it confirmed by the AED. The battery does, however, qualify for the Klimabonus battery grant (up to €2,250 for 9 kWh under the current conditions), which partly offsets this VAT difference.
What self-consumption rate can I expect from a 6 kWp system in Luxembourg?
For a typical 4-person household using 4,500 to 5,000 kWh a year, a 6 kWp system will produce around 5,100 to 5,700 kWh/year (facing due south). Without a battery, the self-consumption rate will be 30–45%, depending on how much you are at home during the day and your consumption profile. With a 6 kWh battery, it rises to 65–75%. With an electric car partly charged during the day, you can exceed 75–80% self-consumption and cover 70–80% of your total electricity needs.
Does self-consumption work during a power cut?
No, not with a standard grid-tied inverter. During a power cut, a conventional inverter shuts down automatically for safety reasons (to protect Creos technicians working on the grid). Some hybrid inverters with a « backup » or « island mode » function can keep certain priority circuits powered during an outage, but this requires a specific configuration and usually a dedicated battery. If this feature matters to you, ask for it explicitly when requesting your quote.
Can I self-consume in a flat in a co-owned building?
Yes, through collective self-consumption (AER-C) within the building. If the co-ownership installs panels on the shared roof, the energy produced can be shared among the participating co-owners according to an agreed allocation key. The decision must be taken at the general meeting, a property manager (syndic) or designated representative coordinates the formalities with Creos, and a sharing agreement is signed. The Klimabonus battery grant is available to co-ownerships if the installation’s capacity exceeds 1.5 kWp per participating private unit.
