In the state of Virginia, citizens who purchase a solar array are eligible for the 30% federal, “Solar Investment Tax Credit.” What this means for you, the consumer, is that if you spend $10,000 on a solar array you will get $3,000 back in tax deductions. Beyond that, there is something called a, “Solar Renewable Energy Credit,” or SREC for short. For every one million watts you produce, or about $115 worth of electricity, you generate one of these SREC’s. States mandate that power companies account for a certain amount of their production through renewable energy and thusly they buy these SREC’s as vouchers for a certain amount of electricity. Currently they are selling for around $45 and are being brokered through Pennsylvania.
