Overview

Overview

The Solar project page is the hub for reading a photovoltaic project from the user side without mixing up the measure itself, Pronovo one-time remuneration, cantonal or municipal aid, self-consumption and grid logic.

What this page helps with

How to use it on maprime.ch

Start from the real need: understand subsidies, position Pronovo correctly, check local logic or prepare the procedure steps. Then move into the related guides, procedures and glossary pages.

  • separating the solar project from the Pronovo-only question
  • understanding when aid depends on the canton, municipality or utility
  • preparing a coherent file between quote, installation, grid notification and remuneration
  • avoiding confusion between self-consumption, battery, RCP, ZEV and grid injection

Available programs

Pronovo - One-time remuneration

Federal

Federal one-time remuneration for eligible photovoltaic installations in Switzerland, with possible cumulation depending on the canton and the energy supplier.

CHF 300 - 600

Federal and cantonal tax deductions

Tax

Your energy renovation costs are deductible from federal direct tax and cantonal taxes. Spread over up to 3 tax periods.

How do you avoid a blockage or rejection in a solar file?

Troubleshooting article for the project-file stage: it explains why solar dossiers get blocked when the project framing, the grid interface and the subsidy logic diverge, and it gives a practical final review to reduce the risk of rejection.

Should Pronovo be requested before or after solar installation?

This article explains why Pronovo timing cannot be reduced to a simple before/after rule: the right moment depends on the programme, the real project status, the documents already available, and the way installation, grid notification, and remuneration are sequenced in a solar project.

What are the steps between the quote, installation, grid notification and remuneration?

This article reads the solar journey as one continuous sequence: project framing, technical installation, grid interface, file preparation and final remuneration. It helps the reader separate technical steps from administrative ones, spot the most frequent blocking points, and run the last consistency check before waiting for payment.

Which documents should you prepare for a subsidized solar project?

This article helps solar project owners assemble a subsidy file in the right order: project core, technical and grid evidence, administrative proofs, then programme-specific and local layers. The goal is a coherent dossier that matches the reality of the installation and reduces avoidable back-and-forth with Pronovo, the grid operator, or cantonal energy services.

What do RCP, ZEV, and grid injection mean in a solar project?

Explain, in a Swiss solar-project context, how RCP and ZEV describe the shared self-consumption setup, how grid injection refers to surplus electricity sent to the network, and why mixing those terms leads to misread project files and imprecise decisions.

What does one-time remuneration mean in a solar project?

Defines one-time remuneration as the federal, Pronovo-based support layer of a solar PV project, explains why it matters when reading the project file, and separates it from local subsidies and the overall economics of the installation.
