What does a home battery do in winter?
In winter you have little solar power left over during the day, so a battery that only charges from solar power is often almost empty. With a dynamic contract it can still charge at cheap hours and discharge at expensive ones.
In the winter months solar panels generate only a small part of what they do in summer, while consumption at home is actually higher. Almost all solar power then goes straight into your own consumption. Little is left to store.
Fixed contract
With a fixed contract the battery earns little in winter, while the losses and standby consumption continue. What it yields per year therefore comes mainly from spring, summer and autumn.
Dynamic contract
With a dynamic contract the battery can also charge from the grid when electricity is cheap, for example when there is a lot of wind, and discharge at the expensive evening peak. That yields something in winter, depending on how large the price differences are.
Look at a whole year
The calculator works through every hour of a year, with the weather and hourly prices of the past year. That way summer and winter both count.
