Frequently asked questions

Is a dynamic contract smart with solar panels?

That depends on what you do with your solar power. On sunny afternoons the market price is low, so feeding back earns little with a dynamic contract. If you use a lot yourself or shift your usage, it can actually be favourable, especially from 2027.

When many solar panels produce at the same time, the market price drops. With a dynamic contract you get the market price of that moment for what you feed back, and on a summer afternoon that is often low or even negative. As long as net metering applies you notice little of this; from 2027 you will.

When it is favourable

When you use a lot yourself during sunny hours, or use cheap hours to charge the car or fill a battery. A battery can store electricity you would otherwise feed back cheaply for the expensive evening.

Negative prices

With a negative price you sometimes pay to feed back. Some inverters and suppliers can then switch off the panels temporarily. How often that happens and what it saves varies from year to year.
