Which solar panel brand is best in the UK?

There's no single 'best' panel — it depends on your roof, budget and how much output you need. Tier 1 brands like REC, LG, Q Cells, JA Solar, Trina and Longi are common premium picks; mid-tier brands can offer good value.

Are more expensive panels worth it?

Premium panels typically offer higher efficiency (more output from limited roof space), longer warranties and better degradation rates. For small or partly shaded roofs they're often worth the uplift.

What warranty should I expect?

Look for a product warranty of 15–25 years and a performance warranty guaranteeing at least 85% output after 25 years. The installer's workmanship warranty is just as important.

Best Solar Panels UK

How to compare brands, efficiency and warranty when choosing solar for a UK home.

The "best" solar panel depends on your roof size, budget and how much electricity you want to generate. Below are the things that actually matter when comparing options.

What to compare

Efficiency: 20–22%+ is good for residential panels. Higher efficiency means more output per square metre.
Wattage: Modern residential panels are typically 400–460 W each.
Product warranty: 15–25 years for the panel itself.
Performance warranty: at least 85% output retained after 25 years.
Degradation rate: the slower the better (look for less than 0.5% per year after year one).

Popular brands UK installers carry

Common Tier 1 names you'll see on UK quotes include REC, LG, Q Cells, JA Solar, Trina Solar, Longi and JinkoSolar. Mid-tier brands can offer good value when paired with a quality inverter and proper installation.

Don't forget the inverter

The inverter is just as important as the panels. Common brands include SolarEdge, SMA, Fronius, GivEnergy and Solis. Hybrid inverters are useful if you plan to add battery storage later.

How to compare like-for-like

Ask each installer to spec the panel brand, model and wattage clearly, and to confirm the inverter and warranty terms. That's the only way to compare quotes fairly.
