The Solar Calculator for Photovoltaic Systems
Planning a solar system is one of the smartest decisions you can make today. You become more independent from your electricity provider, do something good for the environment, and save real money in the long run. The only problem is: without proper calculations beforehand, you can make costly mistakes.
That's why we've developed a calculator that helps you figure out whether a photovoltaic system makes sense for your home and how it should be optimally sized. Simply enter your data and get a realistic assessment of costs and returns.
This way, you can calmly evaluate whether the project makes sense for you before committing. After all, you don't buy a solar system every few years.
