Home solar panel systems with home batteries are being used as backup grid power insurance to help customers understand their energy usage and consumption. The cost of electricity can be significantly reduced if the same kWh costs $0.50 one day, or nearly zero, on another day. This shift in pricing can lead to significant savings. A home battery can be used to stock on electrons when the utility is giving them away, storing them in your battery, and using them when they're priced higher. This gives you more predictability in your monthly budget and more control over an expense that most people consider out of their control. The average homeowner will break even on their installation in about 10 years, with another 10-15 years of energy production still to go. A study found that homes with solar panels installed sold for 5-10% more than comparable homes without solar.
