How solar actually works

“Honestly? Simpler than you’d guess.”
01
Panels soak up daylight
Silicon cells turn light straight into DC electricity — no fuel, no moving parts, and yes, even on a grey British day.
02
An inverter translates it
It converts that DC into the AC power your home, fridge and kettle actually run on — or sends it to a battery.
03
Use it, store it, or sell it
Power your home now, charge a battery for the evening, or export the surplus for a Smart Export Guarantee payment.

Questions, answered straight

Is ByMySun an installer?

No. ByMySun is an independent comparison and education service. We don't sell or fit solar ourselves — we help you understand your options and, only if you ask us to, connect you with a small number of vetted MCS-certified installers who provide quotes.

Are solar panels worth it in the UK?

For most homeowners with a usable roof, yes — typical payback is 8–12 years followed by 13+ years of near-free power, and the case is strongest with a battery on a time-of-use tariff. It's weaker for heavily shaded or north-facing roofs or if you plan to move soon.

Do you cold-call or sell my data?

Never. We only pass your details to installers when you explicitly consent, to a maximum of three, and we don't sell your information on. You stay in control of who contacts you.
