Quick calculation · solar panels

What do solar panels yield without net metering?

How much electricity your panels generate, how much of it you use yourself, what you feed back and what they yield per year, with a fixed or dynamic contract. With generation per month.

1. Your consumption

Electricity use per yearkWhFrom your annual statement; with panels: grid consumption plus what you used yourself from the panels.On how many workdays is someone at home during the day?Whoever is home during the day uses more solar power directly.

A simple estimate with common assumptions: new panels without shade, the average sun in the Netherlands and a standard consumption pattern. Want it more accurate, with the sun at your location (PVGIS), the weather of your measurement year, a home battery or an electric car? Then use the full calculator. To the calculator

An indication, not a quote. Calculates every hour of a year with a standard consumption and solar pattern, like the calculator. Without net metering: power fed back gets the feed-in tariff (fixed) or the hourly price (dynamic).
