Run the Numbers on Your PV System
Work through your PV system with your own numbers: estimated yield, the right feed-in tariff, subsidies, and whether the system pays off. Runs in your browser.

This workflow guides you through the following steps:
- 1. Calculate yield Use the PV yield calculator to see how much power your planned system produces each year.
- 2. Check feed-in tariff Check the feed-in tariff calculator to see what you receive per kWh.
- 3. View funding options Get an overview of possible funding programs.
- 4. Assess profitability Assess payback and profitability of your system.

What you get at the end
An estimated yield, the matching feed-in tariff, a subsidy note, and a payback assessment for your system.
Why these steps in this order
Yield first, then tariff and subsidy, then profitability. Only with yield and tariff can you judge whether the system pays off.
