FAQ

Q1: How do I choose the right solar panel wattage?
A1: Select wattage based on your daily power needs, installation space, budget and system type. 40W-45W panels offer incredible versatility for ultra-compact residential, RV, and DIY off-grid setups.
Q2: What are Voc, Vmp, Isc?
A2: Voc: max voltage; Vmp: optimal working voltage; Isc: max current. Used for safe system matching, wiring, and component selection.
Q3: What is conversion efficiency?
A3: It's the percentage of sunlight converted to electricity. Higher = more power in small spaces. Balance efficiency, space and budget for best value.
Q4: What are the standard dimensions for this solar panel?
A4: For the 40W-45W series, the standard dimensions are 680 x 365 x 25 mm and weight is only 2.6kg.
Q5: What is operating temperature range for solar panel?
A5: -40°C to 85°C (-40°F to 185°F). Efficiency slightly drops in extreme heat; voltage may rise in cold conditions.
Q6: Does power output vary much under different light conditions?
A6: Output peaks in direct sunlight; drops significantly on cloudy days, winter, or with shading. High-quality panels perform better in low light.
