What is Time-of-use, or TOU?
TOU is a new billing structure that in most cases, favors your utility. It means electricity will cost you more depending on the time of day you use it. For example, using electricity between the hours of 4 pm and 9 pm will cost much more than it would at 3 am. Unfortunately, rates are highest exactly when people use electricity the most – in the evening. Homeowners and their families will find themselves having to make lifestyle changes to avoid these higher energy costs.
So, why won’t solar alone fix the TOU problem?
Remember how electricity from the utility is cheapest during the day? This also means solar energy that is exported back to the grid is worth much less. Because the sun is not always shining between 5 pm and 8 pm, solar can’t do much to help offset the cost of that high-priced evening electricity. In other words, TOU dramatically decreases the return on investment you get from a solar power system.
What can I do with a Home Battery?
Self-consumption: Don’t want to go fully off-grid, but want to use as much of your own solar power as possible? Store your excess solar power in your battery during the day and use it at night. If there’s energy left over, sell it to the utility. Not enough energy, buy from the utility.
Backup Power: Keep your family safe and comfortable during a blackout. Have a critical piece of medical equipment that must always stay on? A home business that cannot afford to be offline? Whether it’s a few hours or a few days, batteries are the ideal solution.
Time-of-Use Peak Offsetting: For some utility customers, the cost of electricity changes depending on the time of day. In most cases, electricity is most expensive during the evening when solar systems are not producing energy. Time-of-Use Peak Offsetting allows you to buy a battery just large enough to store the electricity necessary to not pull energy from the grid during these expensive “peak” hours.
Time-of-use: For some utility customers, the cost of electricity changes depending on the time of day. In these cases, electricity is most expensive during the evening when solar systems are not producing energy. Installing a battery just large enough to store the electricity necessary to avoid pulling energy from the grid, allows you to avoid purchasing energy from your utility during these expensive "peak" hours.
Going Off-grid: The ultimate expression of Energy Independence. Generate and store your own electricity. Stay physically connected to your utility or completely discontinue service. Protect your family from future energy rate hikes, changes to net metering, or any of the other ways the utility can reach into your pocket.
A Home Battery.
With a home battery, you can avoid buying your power from the utility. Just store your excess solar power for use during the times of the day when electricity costs are at their peak. Now you’re in control, saving money and gaining more independence from your utility!
