Over-sizing is become a popular theme in solar power plant design in India as there is an increased pressure to drive down costs in installations. Let us understand the technical benefits and dangers of over-sizing solar arrays.
1. Advantages of Oversizing Solar Arrays
1.1 Higher Yield
As all solar EPCs know, a solar array typically never generates at more than 80% of the nameplate capacity or kWp. Thus a 10 kWp solar array, at any given time in Indian conditions would rarely exceed 8 kWp. Thus if we can connect more than 10 kWp of solar panels to a system with a 10 kVA inverter, the net generation or yield of electricity will ofcourse be higher. (more…)
