Are solar panels worth it for Duke Indiana customers?
Yes! For Duke customers in Indiana, adding solar panels can be a worthwhile consideration. Duke no longer offers net metering, however their Excess Distributed Generation Tarriff is also a good option as it does provide the customer with a credit for excess energy generated. This credit is lower than the “retail rate” so you might consider adding battery storage or modifying the system size to maximize how much solar energy is consumed on site rather than sent back to Duke.
Additionally, the availability of the federal tax credit can offset the initial installation costs, making solar more accessible. Furthermore, with Duke’s commitment to expanding its renewable energy portfolio, customers may benefit from a more favorable regulatory environment for solar energy adoption. However, individual circumstances, such as roof orientation, local regulations, and financial situation, should be evaluated to determine the overall value of a solar panel installation.
