Comparisons
Choosing between two options is hard when the differences aren't clear. Here we put common decisions side by side, from panel type to whether a home battery pays for itself. Each page shows what sets the options apart and which option suits which situation.
We keep it practical: no tech for tech's sake, just what affects your bill and comfort. For each topic you'll find honest pros and cons, a short conclusion and frequently asked questions.

All comparisons
From panel type to energy contracts: every comparison in one place.
Fixed vs dynamic energy contract: which fits you?
Fixed or dynamic energy contract: the differences in price and risk, what it means with solar panels or a home battery, and who benefits from dynamic.
Plug-in battery or fixed home battery: which fits you?
A plug-in battery goes straight into a wall socket, a fixed home battery is wired by an installer. The real differences: power, safety and smart control.
Air-to-air vs air-to-water heat pump
Air-to-air (AC unit) or air-to-water heat pump? The differences in hot water, cooling and subsidy, and when each system fits. Honest advice from practice.
Glass-glass vs glass-foil solar panels compared
Glass-glass or glass-foil solar panels? The honest difference in lifespan, warranty, weight and price, and when each build makes sense for your roof.
Single-phase or three-phase home battery: what do you need?
A single-phase home battery works on any connection; a three-phase system charges and discharges harder. Where the difference sits and when upgrading pays.
Heat pump vs gas boiler
Heat pump or gas boiler: the difference in efficiency, cost and comfort, and when a boiler is (still) the logical choice. An honest per-home trade-off.
11 kW vs 22 kW charger: what do you really gain?
