Frequently Asked Questions
QWhat is the difference between PERC and TOPCon technology in 500–550W solar panels?
PERC (Passivated Emitter and Rear Cell) technology adds a reflective layer at the rear of the cell to capture more sunlight, improving efficiency compared to standard cells. TOPCon (Tunnel Oxide Passivated Contact) is a newer generation that further reduces electron recombination losses, achieving higher efficiencies and lower degradation rates. Both options are available across our brand portfolio, and our team can help you select the best fit for your project requirements.
QAre the 500–550W panels compatible with my existing inverter system?
Yes. All panels we supply use industry-standard electrical parameters and are compatible with all major inverter brands, including Sungrow, Growatt, GoodWe, Huawei, SolarEdge, Enphase, Deye, SMA, SAJ, Fronius, Solis, Delta, and many more. Standard MC4 or compatible connectors are available. Our technical team can provide detailed electrical specifications to confirm compatibility with your specific system.
QWhat warranties are included with the 500–550W solar panels?
Our panels come with a 25-year linear power warranty, guaranteeing at least 84.8% of rated power output at the end of the warranty period. First-year degradation is guaranteed at ≤2%, with an annual degradation of ≤0.55% thereafter. All products are genuine and carry full factory warranties backed by the original manufacturers.
QCan I order a mixed container with panels from different brands?
Absolutely. We offer flexible procurement options, including mixed container orders. This allows you to source panels from multiple top brands in a single shipment, making it convenient for distributors, installers, and project developers who require variety or are testing different products for their markets.
QDo the panels perform well in high-humidity or extreme weather conditions?
Yes. All 500–550W panels in our portfolio carry Anti-PID (Potential Induced Degradation) certification, which ensures minimal performance loss in high-humidity environments. They are rated for an operating temperature range of -40°C to +85°C and can withstand front loads of up to 6000Pa (snow) and 3600Pa (wind), making them suitable for a wide range of climatic conditions worldwide.
QHow can I get pricing and availability for 500–550W panels?
As authorized distributors with direct sourcing from top manufacturers, we offer highly competitive pricing. Availability varies by brand and model. Please contact our sales team with your project details — including required quantity, preferred brands, and delivery location — and we will provide a tailored quotation promptly. We also offer support for system design and technical optimization at no extra cost.
