As solar installations proliferate, so grows the need for Princeton Power System’s solution to potentially dangerous power surges on the grid. PPS’s solutions are not aimed at residential rooftop arrays that generate relatively small amounts. But when industrial-sized arrays release large amounts of power onto the grid, a sophisticated way to modulate will be required.

To cite one central New Jersey example, PSE&G is investing $515 million in 80 megawatts of solar arrays in four locations, including Hamilton and Trenton. Yardville Solar Farm, off of South Broad Street in Hamilton, will get 19,000 solar panels on 16 acres, and Trenton Solar Farm, on Brunswick Avenue in Trenton, will get 5,500 solar panels on 5.5 acres.

Together with installations in Flemington and Edison, these projects will produce 80 megawatts of solar, which is enough to power 23,000 homes.

Princeton Power Systems has submitted proposals to PSE&G for solar projects, including Trenton, but the contractors for the above-mentioned and other planned “farms” have not been announced.

As this article goes to press, the owner of the Nassau Park shopping center on Route 1 and Hamilton Marketplace on Route 130, is activating the first five of eight solar installations in New Jersey. SunEdison, based in Beltsville, Maryland, financed the installation, as well as Trenton Solar Farm. Once active, the eight sites will generate 14 megawatts of energy, which — enough to power 4,500 homes — in the first year, according to a press release issued by Developers Diversified Realty, the Ohio-based developer that owns Nassau Park.

The dedication was set for Wednesday, January 20, at 10 a.m.

According to DDR, Hamilton Marketplace will generate 210 kilowatts via two solar arrays, which will feed energy to the 957,000-square-foot retail park. The 1.1 million-square-foot Nassau Park will produce the 120 kilowatts energy via three solar arrays. The energy will be sold by DDR to the stores as an additional source of revenue for the developer.

Princeton Power Systems is not involved in this project, nor any like it, yet. Darren Hammell, executive vice president of PPS, says “We have enough on our plate right now,” but he does not rule out that PPS might one day work with a company such as SunEdison.

SunEdison is mainly a financier of solar projects but neither builds nor supplies hardware. PPS provides hardware for installations capable of generating at least 100 kilowatts — enough to power 10 homes — according to Hammell.
