Solar panels.
More from daylight.

We assess usable space, orientation, shading, roof condition and structural requirements. If the roof needs renovation, it is useful to plan that alongside the solar installation. Your proposed layout and estimated generation should reflect the actual conditions on site.

Partial shade reduces production. Its impact depends on where it falls and how it changes during the day and across the seasons. The assessment informs panel placement and inverter selection. Additional electronics may help manage some losses, but cannot replace missing sunlight.

A grid-connected solar installation can operate without a battery. Storage lets you keep some surplus electricity for later. We consider your consumption pattern, available solar surplus and the additional investment before recommending a battery.

System size, panel and inverter selection, roof construction, mounting, scaffolding and electrical work all affect the proposal. A battery or other equipment adds to the scope. Your quote should identify what is included, with any expected financial support shown separately.

Many rooftop installations follow a notification procedure, while protected buildings or locations can require permission. The project also needs coordination with the local electricity network operator, commissioning checks and the relevant documentation. We review the required steps for your site before work begins.

Check eligibility during planning. Pronovo’s small-system one-off payment application is submitted after the installation is completed; the large-system route also allows applications beforehand. Cantonal or municipal schemes may have different deadlines. Building notifications, grid arrangements and funding applications each have their own timing.
