Net metering offsets exported electricity against consumption and ends on January 1, 2027. Our calculator then assumes €0.01/kWh net export for fixed/variable contracts, or wholesale excluding VAT for dynamic contracts. These are chosen model scenarios, not guaranteed contract tariffs.

The impact depends on several factors: the number of solar panels you have, your consumption pattern, and the type of energy contract you choose. In general, your energy bill will increase because you will be paid less for the electricity you feed back to the grid. Our calculator shows you exactly what this means for your situation, taking into account your specific solar panel setup and consumption profile.

There are several strategies: 1) Increase self-consumption by shifting energy use to sunny hours, 2) Consider a battery to store excess solar power, 3) Switch to a dynamic energy contract to benefit from favorable rates, 4) Invest in energy-saving measures to reduce your total consumption. Our calculator helps you understand which option is most cost-effective for your situation.

Results are model estimates, not a guaranteed bill or saving. We use regional solar data, standard consumption profiles and historical or estimated hourly prices. Actual usage, weather, current supplier terms and future rates can change the outcome. Results disclose the assumptions and price source used.

The calculator uses regional KNMI climate normals, consumption profiles and historical ENTSO-E hourly prices where available. If hourly prices are unavailable, the model can use estimated or synthetic prices; results label this. Fixed tariffs and export payments are disclosed model assumptions or your own inputs, not a live market comparison.

Your inputs are sent to our server for calculation. Inputs and results stay in browser session storage for the results page. Technical request information can appear in logs or caches.

It depends on how much additional solar energy you can use at home, your contract and the total battery cost. Compare the same situation with and without the battery, including required equipment, installation, annual costs and degradation. Our battery calculator compares capacities and lets you edit the total price. Payback is an estimate, not a purchase guarantee.

With a dynamic contract, you pay the hourly spot price for electricity instead of a fixed rate. This allows you to benefit from low prices (often at night and during sunny, windy days) and avoid high prices. For solar panel owners, this can be attractive because you can optimize your consumption and feed-in. However, it requires more active management and comes with some price uncertainty. Compare all providers to find the best dynamic contract for your situation.

This is highly personal and depends on your consumption pattern, the size of your solar panel installation, and your willingness to actively manage your energy consumption. Our calculator analyzes your specific situation and provides a tailored recommendation. In general, we see that: for small installations (<10 panels) often only shifting consumption helps, for medium installations (10-20 panels) a dynamic contract is often most cost-effective, and for large installations (>20 panels) a combination of battery and dynamic contract can be worthwhile.
