Another step towards efficient use of solar energy: decentralized inverters in solar panels.

Enphase Energy came up with efficient DC-AC microinverters located on each panel. The design is more efficient because it better handles partial shading and adds reliability to the overall system.

“There’s been very little question on the benefits of microinverters, but people didn’t think it was possible to get the efficiency levels required. A microinverter must be developed from the silicon level up to make it work efficiently.”

Enphase Energy has been able to improve the DC-to-AC conversion efficiency to around 95 percent, on par with centralized inverters.
