FAQ
What is the actual average daily output of one 550W panel?
Daily output depends heavily on location and sunlight hours. As an estimate, in a region with 5 peak sun hours, one panel can generate approximately 2.75 kWh per day (550W * 5h = 2750Wh). Annual yield can be accurately modeled using local solar irradiance data.
Are these panels compatible with mainstream string and microinverters?
Yes. The electrical parameters (Voltage and Current) of our painel solar 550w are designed to be fully compatible with major 1500V string inverters from brands like Huawei, Sungrow, SMA, and others, as well as high-power microinverters.
How does half-cell technology improve performance?
Half-cut cells lower the current within each cell string, reducing resistive (I²R) losses. They also make the panel more resistant to partial shading; if one half is shaded, the other can often continue operating near full capacity.
What does the 25-year linear power warranty cover?
We guarantee that the panel will deliver at least 97% of its rated power in the first year. Thereafter, the annual degradation will not exceed 0.55%, ensuring a minimum of 84.8% of original power output by the end of year 25.
Do you provide samples, and what are the payment terms?
Yes, we provide sample panels for qualified B2B clients. Standard payment terms include T/T or LC, with flexible options negotiable for large-volume orders. Contact our sales team for a detailed quotation and sample policy.
