California’s transition to mandatory Time-of-Use (TOU) rates has changed the solar savings landscape. For solar homeowners, understanding these rate structures is crucial for maximizing returns on your investment. The good news? Smart solar design and usage patterns can actually increase your savings under TOU rates.
The basic concept is simple: electricity costs more during high-demand hours (typically 4-9 PM) and less during off-peak times. Solar production peaks during midday, when rates are lower, but smart system design and modern technology help bridge this gap. Our California customers are finding creative ways to maximize savings under these new rate structures.
Battery storage has become increasingly valuable under TOU rates. By storing excess solar production from midday hours, homeowners can power through expensive evening periods without drawing from the grid. The math is compelling—storing solar energy produced at $0.22/kWh to offset evening rates of $0.48/kWh doubles your savings impact.
The seasonal variation in California’s TOU rates creates unique opportunities. Summer peak rates often run 50-100% higher than winter rates, making solar particularly valuable during hot months. Strategic timing of high-consumption activities like pool pump operation, EV charging, and air conditioning can significantly impact your savings.
Real data from our California installations show impressive results. Homes optimized for Time-of-Use (TOU) rates typically save 15-25% more than those on standard rate plans. This optimization often involves simple changes like running dishwashers and laundry during solar production hours and using smart thermostats to pre-cool homes before peak periods.
Electric vehicle owners face unique opportunities with TOU rates. Charging during peak solar production essentially makes your driving fuel-free, while evening charging could cost three times more. Smart EV chargers can automatically optimize charging schedules to take advantage of the lowest rates.
Climate patterns in California align well with solar production. Coastal morning fog often burns off just as rates decrease, maximizing the value of your peak production hours. Inland areas benefit from consistent sunshine during mid-day hours when rates are most favorable.
