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.

Common decisions, laid out clearly by our experts.
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 home battery or fixed home battery: which fits you?
A plug-in home battery goes into a wall socket: about 800 watts, you handle the safety, no energy label. A fixed system covers more.
Air-to-air or air-to-water heat pump
Air or water? An air-to-air (AC unit) or an air-to-water heat pump: what that means for hot water, cooling and subsidy, and which system fits your home.
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
A heat pump boiler is the heat pump that takes over from your gas boiler: efficiency, cost and comfort, and when a boiler still makes sense.
11 kW vs 22 kW charger: what do you really gain?
A 22 kW charger sounds twice as fast as 11 kW, but your car and connection decide what you actually charge. The honest trade-off for home.
