Frequently Asked Questions
What is the main difference between the LB and GB series panels?
The LB series panels are slightly larger and offer a higher power output (up to 455W) and efficiency (up to 22.8%) compared to the more compact GB series. The LB series is designed for projects where maximising power generation is the top priority.
What is N-type TOPCon technology?
It is an advanced solar cell architecture that improves efficiency and reduces degradation over time compared to older cell types. This results in higher energy yields over the lifetime of the panel.
Are these panels a good investment?
Yes. While they are a premium product, their high power output and exceptional efficiency mean they generate more electricity over their lifespan. Combined with a 30-year power warranty, they offer excellent long-term value and a strong return on investment.
How does the 30-year power warranty work?
JA Solar guarantees that the panels will not lose more than 1% of their power output in the first year, and no more than 0.4% each year after that for 30 years. This ensures your system will continue to produce significant amounts of power for decades.
