Microinverters can Improve Performance under Shaded Conditions more than 12%

Monday, May 14, 2012
The US Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) has released a new repeatable test protocol that simulates real shade conditions and can predict with much greater precision the effects of shade on a solar array.
The new test demonstrated that under heavy shading conditions the use of microinverters instead of typical string inverters can help mitigate the impacts of shade by improving system performance by more than 12 percent.
