Lightweight PV Inverters
Technology Description:
PV inverters convert DC power generated by modules into usable AC power. Ideal Power's initial 30kW 94lb PV inverter reduces the weight of comparable 30kW PV inverters by 90%—reducing the cost of materials, manufacturing, shipping, and installation. With ARPA-E support, new bi-directional silicon power switches will be developed, commercialized, and utilized in Ideal Power's next-generation PV inverter. With these components, Ideal Power will produce 100kW inverters that weight less than 100lb., reducing the weight of conventional 3,000lb. 100kW inverters by more than 95%. The new power switches will cut IPC's $/W manufacturing cost in half, as well as further reduce indirect shipping and installation costs.
Potential Impact:
If successful, Ideal Power would reduce the weight of PV system components by 95%—significantly reducing the cost to manufacture, ship, and install PV systems.
Security:
Lowering the cost of PV systems would help increase the use of solar energy, which in turn would decrease our dependence on fossil fuels and improve U.S. energy security.
Environment:
Solar energy systems create zero harmful emissions while providing energy to homes and businesses, so their widespread use would significantly improve air quality.
Economy:
This project could help position the U.S. as a leader in the power electronics industry.
