AES Indiana commercial and industrial customers should consider whether their electric service rate includes a charge for demand (kW). Solar panels may have no impact on monthly demand, since there are periods of darkness, storms, or otherwise low production from solar panels. In addition, solar power can have a negative impact on the overall Power Factor for that service.
