Selling PV Systems! Educating or Misleading Customers?

Selling has many connotations as well as definitions. These fall into two general categories, educating and misleading the potential customer.

How much energy is lost due to inverter clipping when the power form the PV array far exceeds the inverter output rating? And under what conditions do the losses occur?

Today’s interactive inverters allow high PV to inverter size ratios. An example 7.7kW residential inverter allows a PV array STC input rated up to 12.32kW; that is a 160% oversizing. Some utility scale central inverter design allows up to 200% oversizing of the PV array.

There are many elements involved in achieving this perfect design that is just right for the customer. If you know these elements, it makes the goal very attainable. The first one is to provide the customer with  what they want and need; these two may not be the same and the need may sometimes have to stand in for what they want.
