The total current is 6A - not 7. 5A average, not 9A, but 6A limited by the weaker panel. For parallel wiring, mixing different panels is more forgiving (different voltages cause some mismatch but less severe losses).
For charging a 400Ah battery, a recommended solar panel size is approximately 800 to 1,600 watts. This recommendation depends on the daily power requirements and sunlight availability.
As of April 2026, the average solar panel system costs $2. 63/W including installation in Saint George, UT. 4 kW system (the average system size in Saint George, UT), this comes out to about $43,149 before any available incentives, though prices range from $36,677.
Q: What's the installation cost per kWh? A: $150-$300 depending on site accessibility. Q: Are government subsidies available? A: Yes - the PROSOL ELEC program covers 30-45% of BESS costs for solar integrations. Need a customized BESS quote?.
Surface Quality: Inspect the tempered glass for smoothness and any leftover silicone residue, as this can reduce the panel's efficiency. Panels made from broken cells pose safety risks and reduce long-term performance.
