Solar or electric water heater? By the numbers
An honest money comparison of solar vs electric — which is cheaper upfront, which saves long-term, and who each suits.
In short: an electric heater is cheaper upfront and simpler to install, but it heats with electricity all the time, so the bill is higher. A solar heater costs more upfront and needs a roof, but it heats from the sun for free, so it saves over the long run. The right choice depends on: do you have a roof that gets sun, and how much do you use? This article compares by the numbers, honestly, so you can decide.
The cost difference — upfront and monthly
Solar heater · Electric heater
Upfront cost · Higher (system + install) · Lowest
Monthly bill · Lowest (heats from the sun) · Higher (daily electric heating)
Long term · Pays back, then saves · Cost keeps stacking on the bill
Needs roof/sun · Yes · No
Installation · A bit more involved · Simple

So which suits you?
Let’s be honest instead of selling:
- Solar suits you if: you have a sunny roof, medium-to-high usage, and want long-term savings. Here solar clearly wins.
- Electric suits you if: there’s no suitable roof, usage is very low and individual, or your upfront budget is limited right now.
This neutrality is deliberate — the best decision is the one that actually fits your home, not the one we’re selling. (Wider view in Is a solar heater worth it?.)
