SunSil Drives Electronics Deeper Into the Solar Panel

Greentech Media
Sunsil of Denmark has upped the technology ante in the integration of PV solar modules and power conditioning electronics. (...) Microinverters and panel optimizers maximize output for each module; SunSil's design goes a step further and adds their "dynamic microcell controller" at the solar-cell level within the module and addresses this cell variation, as well as panel shading and panel soiling. Maximum Powerpoint Tracking is being done at the cell level and the panel puts out alternating current.
Sunsil takes a backside-contact, 17-percent-efficient solar cell, scribes it with a laser and breaks the cell into sub-cells. Each solar module uses 576 sub-cells, along with 48 DC-to-DC converters. (...) With production help from Dutch firm Eurotron, SunSil is building a 300-watt, 230-volt AC module (ACM) -- one that produces 20 percent to 40 percent more kilowatt-hours per year than a standard module.
Hansen claims inverter efficiency of better than 96 percent, using space-grade components. The end product is guaranteed for 25 years.
