Electrical-products company Princeton Power Systems makes components for the solar industry - and it will soon demonstrate its technology by putting it into service.
The Princeton, New Jersey-based firm, which makes inverters used in solar installations, is planning to construct a $1.5 million solar power system at its headquarters. The installation will include a 200-kilowatt solar array, but the showpiece of the project may be its energy-storage system.
PPS' solar project includes lithium-ion batteries provided by a Pennsylvania company. Two hundred kilowatt-hours of storage capacity will be provided initially; PPS says it can upgrade to 1 megawatt-hour of storage if need be.
Systems like PPS' should grow common in the coming years, as the need for smart grid-integrated solar and wind arrays becomes acute. Integrating alternative energy into the grid, PPS executive vice president of business development Darren Hammell said, "is possible and cost-effective today, using available technologies."
Indeed, because renewable-energy installations can produce electricity erratically, battery systems may be required to ensure their widespread adoption. If PPS' solar project proves to be a success, more like it could appear on the clean-energy landscape.
