9.66kW roof-mount solar electric system

This project presented partial shading from tall trees on the southeast side of the property. This micro-inverter based system was designed to offset 75% of the homeowner’s energy usage. Micro-inverters offer several advantages over string inverters:

• Shade Mitigation: Micro-inverters are much better at shade mitigation. With a string inverter if any portion of the array is shaded the whole system will be affected, but with micro-inverters, only the shaded areas are affected – the remaining panels operate at full capacity.
• No single point of failure: When a string inverter fails, the whole system shuts down, but with a micro-inverter failure only that portion of the array is affected – the rest of the system remains operational.
