For more than a decade, the success of solar as a business has required relatively stable rates and incentives. Unstable incentive structures (expiring incentives, inadequately funded incentive mechanisms, etc.) have been the one of the greatest limiting factors to DG industry growth. Consumers who don’t have confidence that solar savings estimates are accurate won’t commit to contracts, limiting market growth. Similarly, if DG companies are unsure about how long a particular incentive or rate structure will last, they won’t invest to expand their businesses (hiring, capital purchases, etc.).
