Zonvolt

Zonvolt is an independent energy information platform that helps households make informed decisions about home energy. Its focus is on clear calculations and comparisons rather than sales messaging, so visitors can assess options using figures relevant to their own circumstances. The site offers online tools for estimating whether a home battery may pay off, including comparisons between the current net-metering system and the rules expected after it ends on 1 January 2027. Users can also calculate the potential impact of that change, compare dynamic and fixed energy contracts based on household consumption, and review electricity suppliers’ net annual costs when exporting power.

Zonvolt covers home batteries, dynamic energy, feed-in charges, solar panels, heat pumps, insulation, energy saving and available subsidies. Its calculators explain their methods, and the platform cites sources including the Dutch government, the ACM, Milieu Centraal, the Tax Administration, RVO, EPEX and CBS. Zonvolt may receive affiliate compensation when users request a quote or switch contracts, but states that this does not affect its calculations or add to the user’s cost. It does not provide personal financial advice.
