Solar Energy Incentives: Rebate vs. Portfolio Energy Credits Comparison
State Rebates and Portfolio Energy Credits or PECs (also called Solar Renewable Energy Certificates or SRECs in many states) have been fundamental in the development of the Solar industry. The rebate seems like a no-brainer- a couple of thousand dollars off the total project cost of your system can make or break a deal when it comes to Solar. But – what are you giving up by taking this rebate? Below are some tips on making the decision to take the rebate or keep your PECs from an expert on the subject.
In Nevada, NV Energy is currently offering a rebate of $0.40/watt for rooftop solar installations*. This amounts to $1,000 to $3,000 for an average-sized system. Nevada opened up this rebate with the intention of leaving it open until all the money in the State fund has run out. As more people sign up for the rebate the amount offered ($0.40/watt) will decrease, giving you a smaller incentive for the same size system.
When you accept the NV Energy rebate you hand over your PECs to NV Energy. One PEC is equivalent to 1 kWh of generation from a qualifying renewable energy source. As your solar system continues to generate energy, you will accumulate PECs that have value at NV Energy.
NV Energy uses these PECs to meet state standards for renewable energy production (Nevada’s Renewable Portfolio Standard or RPS requires NV Energy to be 25% renewable energy by 2025). In the past, NV Energy has paid out $300 to $800 for an average size system for a single year of generation. Over the life of your system, it’s clear that you can earn more money back from PECs than from the rebate. The issue with PECs (or if you’re into economics – an interesting issue) is that it’s a market-based policy, meaning that it’s based on supply and demand so getting money back every year is not guaranteed.
