Which home EV chargers can use surplus solar generation to charge your car for free — and which ones just claim to.

Working backwards from your electricity bill and roof to the right system size — without the vague installer estimates.

Installing solar panels can improve your EPC rating by 6–10 SAP points — enough to unlock green mortgage discounts, cashback rewards, and 0% additional borrowing from major UK lenders. This guide explains which products are available, who qualifies, and how to make solar and your mortgage work together.

A furnished holiday let is not a standard rental in the eyes of HMRC or the EPC register, and that changes the maths on solar panels. This guide covers the EPC E minimum that applies instead of the 2030 EPC C deadline landlords face, what the April 2025 abolition of the furnished holiday lettings tax regime means for claiming solar as a business expense, whether 0% VAT relief on installation still applies to a holiday cottage, and how peak summer occupancy lines up with peak solar generation.

Fitting solar panels yourself is legal in the UK, but the line between "allowed" and "sensible" is narrower than most DIY guides admit. This guide covers what you can genuinely do yourself, the electrical and building-control work you can't, the DNO notification every self-installer still owes, and the two financial incentives — the Smart Export Guarantee and 0% VAT — that a self-install gives up.

Snow and hail rarely damage a properly installed UK solar panel system — the panels themselves are impact-tested and the mounting is load-tested to UK standards. This guide covers what those tests actually check, how panels shed snow, when ice becomes a real hazard, and why you should never climb up to clear snow off panels yourself.

A neighbour's tree isn't automatically a legal problem, and there's no statutory 'right to light' for a roof full of solar panels. But a shading extension is a different story since a 2019 High Court ruling forced councils to treat loss of sunlight to solar panels as a material planning consideration. Here's what actually works: the high hedges route, the planning objection route, and what a good installer does at the survey stage to avoid the dispute altogether.

TOPCon has overtaken PERC as the dominant solar panel technology in 2025–2026. Here is what that actually means for efficiency, degradation, and whether the premium is justified for a UK install.

For most UK households with a south-facing roof and reasonable daytime use, solar panels are worth it — payback typically falls in the 8–12 year range, with ongoing savings for 15–20 years beyond. But north-facing roofs, significant shading, and households out all day with no battery make the case much harder to justify. This guide sets out who benefits, who should think carefully, and what the real numbers look like.

Q Cells (Hanwha Qcells) is one of the best-known solar brands among UK homeowners, backed by South Korea's Hanwha Group and built on German engineering roots. This review covers the Q.TRON and Q.PEAK DUO ranges sold through UK installers, their efficiency and warranty terms, current UK pricing, and how the brand stacks up against mainstream Chinese rivals.

The honest answer to how much solar output drops in winter, what drives the drop, and whether it changes the payback calculation.

The honest carbon maths behind home solar — how fast panels repay the emissions used to make them, what a kWh actually displaces, where a battery fits, and the limits of what solar can fix.
