Why your solar system size is larger than the inverter?

Hello Solar friends, It's Channel from PurePoint Energy. We have been getting questions from clients about their solar system size and inverter size. "Why is the system size larger than the inverter?', "Is this dangerous?", "Am I wasting power?". I am here to answer all these questions!

Why oversize your system?

• The goal of designers is to ensure maximum energy harvest from each module in the system. By doing so, designers ensure the optimal use of this high-cost system component. 

• By maximizing production per module, designers achieve the optimal specific yield of the system.

• Since a larger array feeding a fixed size inverter will result in greater system annual production, the increased annual energy harvest is spread across the system’s fixed/semi-fixed costs, which include inverters, AC collection system, permitting, interconnection fees, engineering and overhead.

Are you wasting power/ Is this dangerous?

• When the available DC power from a PV array exceeds the inverter maximum power rating, the control logic in the inverter responds by moving the PV array off its maximum power point.
• Limiting power in this manner ensures that excess power is not dissipated as waste heat in the inverter.
• The inverter components are not exposed to this excess power under normal operating conditions.
• NO, it is not dangerous at all!
