Utility Rate Optimization
Time-of-use versus flat rate, demand-charge exposure, and community solar compared honestly against rooftop solar and against doing nothing.
Utility rate optimization is often the cheapest lever on this whole site, since a time-of-use switch or a scheduling change can cost nothing and still save real money, but only for a household whose usage pattern actually fits the rate plan being pitched. These engines also cover demand charges, community solar as a no-roof alternative to rooftop, and how to separate a bill's fixed fees from the portion any purchase can actually reduce.
