Determining the number of solar panels I need for my new 30 amp solar charge controller has had me scratching my head, but I've learned it's actually pretty straightforward once I have some key details about my solar electric system. In this comprehensive guide, I'll walk through the main factors. . System Efficiency Reality Check: Real-world solar systems operate at only 75-85% of their theoretical maximum due to inverter losses, wiring resistance, soiling, shading, and temperature effects. Factor in an 80-82% system efficiency for accurate calculations rather than using nameplate panel. . With 4 hours of effective sunlight, one panel produces: 300W × 4 hours = 1,200 Wh or 1. If your house uses 30 kWh per day, then you need: 30 kWh ÷ 1. That result gives a target system wattage to meet your needs. Provide Location Details: The amount of sunlight your location receives (solar irradiance) affects the efficiency of solar panels.
