You don't need solar panels to tap into cheap electricity rates - in fact you can get quicker returns without them. With time-of-use tariffs, you can exploit the surplus energy generated during off-peak hours, often when wind farms and renewables flood the grid. In some instances, the National Grid via energy companies, provide additional revenue to home battery owners for providing services to the grid. This could be as simple as, for example, charging your battery at night (8p/kWh) and receiving a payment for providing the grid with power at a time they need it for a much higher rate. Imagine getting paid by the energy companies to power your home, from lights to appliances. It's the ultimate win-win, it's smart, efficient, and puts money back in your pocket. This is the reality of where we now are with battery storage systems for your home.
