Leapton Energy is a Japanese-headquartered solar panel manufacturer offering budget-friendly Tier 1 panels. Here's our independent review covering specs, PVEL reliability test results, and whether Leapton panels are a good choice compared to Jinko and JA Solar for UK homes.
Quick Answer
Leapton solar panels are a solid budget Tier 1 option for UK homes. At £120–£200 per panel they are 20–30% cheaper than Jinko or JA Solar. The 440W N-type TOPCon panels offer 22.0% efficiency and scored as a top performer in 4 PVEL reliability tests. The trade-off is a weaker performance warranty (80.68% at year 25 vs Jinko's 87.4% at year 30) and lower brand recognition in the UK.
Who Are Leapton Energy?
Leapton Energy is headquartered in Tokyo, Japan and was founded in 2017. Despite the Japanese headquarters, panels are manufactured in Changshu, China. Leapton has quickly achieved Bloomberg NEF Tier 1 status and their products are available in over 70 countries.
Leapton is less well-known in the UK than Jinko or JA Solar, but they are available from some UK installers and are often discussed on UK solar forums as a budget alternative to the big-name brands.

Thermal Cycling
Top Performer
Mechanical Stress
Top Performer
Hail Stress
Top Performer
LID + LETID
Top Performer
PVEL is an independent testing lab (now part of Kiwa). These results suggest Leapton panels hold up well under harsh conditions despite their budget pricing.
Leapton vs Jinko Solar: Which Is Better?
| Feature | Leapton LP182 | Jinko Tiger Neo |
|---|---|---|
| Wattage | 440W | 440W |
| Efficiency | 22.0% | 22.3% |
| Product Warranty | 25 years | 25 years |
| Performance Warranty | 25 years (80.68%) | 30 years (87.4%) |
| Degradation | 0.5%/year | 0.4%/year |
| Temperature Coefficient | −0.30%/°C | −0.29%/°C |
| Typical Price (per panel) | £120–£200 | £150–£300 |
| PVEL Top Performer | Yes (4 tests) | Yes |
Verdict: Jinko is the stronger panel on every spec, particularly the performance warranty (87.4% at year 30 vs 80.68% at year 25). However, Leapton is 20–30% cheaper. If budget is tight, Leapton is a credible Tier 1 alternative with strong reliability test results. If you can afford the extra £30 per panel, Jinko is the better long-term investment.
