Solar energy output is outpacing Pa. mandate

While the sun beat down last week on a $187,000 rooftop solar system on his Chester County barn, Edward Frankel watched his electrical output add up.

Every two minutes, a meter ticked off another kilowatt-hour of power generated by the 150 solar panels Frankel installed last year at his Honey Brook farm.

For every 1,000 kilowatt-hours the system produces, Frankel earns one Solar Renewable Energy Credit - an SREC, the coin of the realm in green energy.

"Almost 37 SRECs," Frankel, a veterinarian, said as he watched the cumulative total on the electric meter climb toward 37,000 kilowatt-hours. "Yes!"

Last year, Frankel was more enthusiastic about SRECs, when utilities paid him more than $300 for each credit. Now a cloud is gathering over his cash flow. The SREC price has crashed to under $100.

Story continues below.

"I think you'd be nuts to build a system in Pennsylvania today," said Frankel, 73. He canceled plans to install a second solar system on his veterinary practice, the Honey Brook Animal Hospital.

Pennsylvania's booming solar industry is going bust.

Attracted by 30 percent federal tax credits and state grants aimed at stimulating pollution-free electricity production, Frankel and thousands of other property owners went solar in the last two years. Taxpayers covered $106,000 of Frankel's 30-kilowatt system, or 57 percent of the cost.

Enthusiasts like Frankel were also counting on receiving solar energy credits for the power they produce to make their projects work. The costs of the credits are paid by electricity consumers rather than taxpayers.

But about 71 megawatts of solar capacity is now in place in Pennsylvania, while a 2004 law requiring utilities to buy a steadily increasing portion of renewable power envisions a demand of only 42 megawatts. The result: SREC prices are falling faster than anticipated.

The solar industry says the market may remain oversupplied for several years unless the legislature steps in. It is lobbying Harrisburg to accelerate the annual increases for solar-power mandates for the next three years.

Legislation introduced by State Rep. Chris Ross (R., Chester) would also ban out-of-state projects from selling their credits to Pennsylvania utilities.

Solar advocates say the changes would not cost consumers very much since solar energy still would make up less than one-tenth of 1 percent of the total power utilities must buy. The bill would also not change the state's target for 2021 that 0.5 percent of electricity must come from the sun.
