The canton of Basel-Landschaft pays no contribution of its own per kWp for photovoltaics. What is supported is the combination: anyone who insulates the roof or facade through the Energiepaket and builds a PV system at the same time receives, since 1 January 2026, an additional CHF 40.– per m² of module area on the roof or CHF 120.– per m² on the facade. On top come the federal one-off feed-in incentive (around CHF 360.– per kWp), municipal funds such as in Binningen and the full tax deduction. (As of: November 2026)
Key points in brief
- The basis is the federal one-off feed-in incentive via Pronovo – around CHF 3’600.– for a typical 10 kWp system.
- The cantonal PV bonus applies only together with subsidised roof or facade insulation and is applied for in the same Energiepaket application.
- Some municipalities add to this: since 2026, Binningen additionally pays 25 percent of the Pronovo contribution (up to 9.99 kWp).
- Taxes: energy-saving investments in existing buildings are 100 percent deductible in Baselland and can be carried over to the two following tax years.
- The grid operator in most municipalities around Basel is Primeo Energie (for example Allschwil, Binningen, Reinach, Muttenz), in the Liestal area EBL.
What does the federal government pay – regardless of canton and municipality?
The one-off incentive (EIV) is also the main support in Baselland: around CHF 360.– per kWp for a roof-mounted system up to 30 kWp, around CHF 400.– per kWp for a roof-integrated one. It is not budget-capped and not location-dependent; anyone who meets the conditions and submits the application properly after commissioning receives it. Process and typical mistakes: Pronovo registration.
As of: July 2026 (EIV); the current Pronovo rates are authoritative.
Energiepaket BL: the bonus for insulation plus photovoltaics
The cantonal Energiepaket does not support a pure PV system. The canton starts with the building envelope – and, since 1 January 2026, explicitly rewards mounting solar modules straight onto the freshly insulated roof or the insulated facade:
| Measure | Incentive contribution |
|---|---|
| Thermal insulation of roof or facade | CHF 40.– per m² of insulated area |
| PV bonus on the insulated roof | + CHF 40.– per m² of module area |
| PV bonus on the insulated facade | + CHF 120.– per m² of module area |
Source: Energieförderverordnung Basel-Landschaft (Energy Incentive Ordinance, SGS 490.10), Annex 1, contribution rates from 1 January 2026; energiepaket-bl.ch. The current conditions and the commitment in the individual case are authoritative.
What is included:
- The PV bonus is applied for in the application for thermal insulation, not separately. Without subsidised insulation, there is no bonus.
- Per measure, at most 50 percent of the specific investment costs are subsidised; the cost of the PV system itself is deducted.
- Maximum CHF 100’000.– per application; contributions under CHF 500.– are not paid out.
- The commitment is valid for 36 months – enough time to plan roof and system properly.
To give an idea of scale: anyone who insulates 120 m² of roof and covers 80 m² of it with modules gets CHF 4’800.– for the insulation and CHF 3’200.– PV bonus – before checking the 50 percent limit and in addition to the one-off incentive. On the facade, the bonus is three times as high, because facade systems are more expensive and produce more in winter. Why a roof renovation is the best moment for a system: Roof renovation with photovoltaics.
Battery storage is not listed in the Energiepaket contribution rates; the one-off incentive also applies only to the PV system. Anyone planning storage should calculate it without a cantonal contribution.
Which municipalities pay extra?
Municipal programmes vary in Baselland and are mostly tied to a budget. One documented example:
- Binningen: Since 1 January 2026, the municipality's energy fund additionally pays 25 percent of the Pronovo contribution for private systems, calculated on at most 9.99 kWp. Only applications for which a commitment or payout from the federal government or canton already exists are processed.
For Allschwil, Reinach, Muttenz, Pratteln, Liestal and the other municipalities, it's worth checking the municipality's website or energiefranken.ch – many programmes change every year. We check this for your address as part of the quote. How to find municipal programmes yourself: Finding your municipality's incentive.
Notification procedure: when is notification enough?
A sufficiently adapted roof system needs no building permit in Baselland either; it is subject to notification (§ 104b Spatial Planning and Building Act). The notification goes in writing and before construction starts to the cantonal building inspectorate; in individual municipalities such as Reinach, the municipality receives it.
A building permit is required in core zones, townscape zones and protection zones, as well as for cultural and natural monuments of cantonal or national importance. Many Baselland village cores – from Allschwil to Liestal – lie in such zones; in that case a building application replaces the notification and takes correspondingly longer. What a complete dossier contains: Notification procedure for solar systems. We clarify the zone before the quote and submit the notification or building application for you.
Taxes in Baselland: full deduction, spreadable over three years
Energy-saving investments in existing buildings are treated as maintenance costs in Basel-Landschaft and are 100 percent deductible from taxable income – even if they increase the property's value (§ 29 para. 2bis Tax Act BL). Three points make the difference:
- Spreading: What cannot be offset in the year of investment can be carried over to the following and the next-but-one tax period.
- Flat-rate or actual: Anyone who chooses the flat-rate deduction for the year cannot additionally deduct the solar system. In the year of investment, deducting the actual costs is therefore usually worthwhile.
- New builds excluded: If the system is ordered less than two full years after moving into a new building, it counts as part of construction and is not deductible.
Incentive contributions are deducted from the deductible costs; you pay tax on feed-in income net, i.e. after deducting electricity purchases. Basics and worked examples: Deducting a solar system from tax. The guidance and tax manual of the cantonal tax administration are authoritative.
Who is your grid operator – Primeo or EBL?
The feed-in tariff is determined not by the canton but by the utility at your address. In lower Baselland that is usually Primeo Energie: according to the grid area map, they include Allschwil, Binningen, Oberwil, Münchenstein, Reinach, Arlesheim, Aesch and Muttenz. In the Liestal area it is EBL. In Pratteln, checking address by address is worthwhile.
In 2026, both utilities pay according to the federal quarterly reference market price, backed by the statutory minimum remuneration of 6.00 Rp./kWh for systems up to 30 kW. Differences lie in the guarantee of origin: EBL pays 3.00 Rp./kWh for it, Primeo 2.00 Rp. in the first quarter and 0.50 Rp. in the remaining quarters. For 2027, neither has yet published a feed-in price sheet. Context and comparison: Feed-in tariffs Basel and Bern.
As of: 2026 price sheets of Primeo Energie and EBL; your grid operator's current tariff sheet is authoritative.
How to clarify your situation in 3 steps
1. Insulation planned? Then register PV in the Energiepaket application right away – otherwise the bonus lapses. 2. Check the municipality: municipality website or energiefranken.ch; in Binningen only after the commitment from the federal government or canton. 3. Keep to the sequence: Energiepaket application → notification or building application → connection application to Primeo or EBL → construction → commissioning → Pronovo application → municipal application → deduction in the tax return.
With every ecoEn quote, clarifying the incentive situation at your location is standard – including the applications.
The most common question from Baselland is not «What does the canton pay?» but «Is it worth it at all without cantonal incentives?». The answer usually lies in tax: the full deduction, spread over up to three tax years, often has a stronger effect on a typical single-family-home system than any flat-rate contribution – it just doesn't catch the eye as an incentive notice. Anyone who is insulating the roof anyway should not give away the Energiepaket bonus: it depends solely on the system being in the right application.
Frequently asked questions
Does the canton of Basel-Landschaft support solar systems?
Not with a contribution per kWp. Since 1 January 2026, however, the Energiepaket offers a bonus when roof or facade is insulated and covered with PV at the same time: CHF 40.– per m² of module area on the roof, CHF 120.– per m² on the facade, in addition to the insulation contribution of CHF 40.– per m². The basic incentive remains the federal one-off feed-in incentive.
How do I apply for the Energiepaket PV bonus?
In the application for thermal insulation of roof or facade on energiepaket-bl.ch – there is no separate PV application. At most 50 percent of the specific investment costs are subsidised, at most CHF 100’000.– per application; the commitment is valid for 36 months.
Is battery storage subsidised in Baselland?
No storage is listed in the contribution rates of the cantonal Energiepaket, and the federal one-off incentive applies only to the PV system. The Binningen energy fund also names no storage contribution. For tax purposes, storage can be deducted together with the system.
Can I deduct a solar system from tax in Baselland?
Yes, on existing buildings at 100 percent as an energy-saving investment, and costs that cannot be offset can be carried over to the two following tax periods. In the same year, either the flat-rate deduction or the deduction of actual costs is possible, not both. Incentive contributions received are deducted.
Is Allschwil on the Primeo or EBL grid?
According to the 2026 grid area map, Allschwil belongs to Primeo Energie, as do Binningen, Oberwil, Reinach, Münchenstein, Arlesheim, Aesch and Muttenz. EBL is the grid operator mainly in the Liestal area. The address is decisive; we check this during the site visit.
Does ecoEn work in Baselland?
Yes, we also carry out projects in the Basel region – planning, installation and electrical connection with our own team, including registration with the grid operator and the Pronovo application. Our head office is in Zurich. Everything about the region: Solar system in the Basel region.
