Solar Panel Sizing
The number and capacity of solar panels depend on energy requirements, available sunlight, system losses, inverter specifications and installation space.
- Total PV capacity
- Panel voltage and current
- Series and parallel configuration
- MPPT operating range
- Maximum PV input voltage and current
- Roof or ground mounting space
- Expected daily energy production
The solar panels do not necessarily have to have the same wattage as the inverter. The PV array is designed according to the inverter specifications and energy requirements of the system.
