No, you don’t need a solar battery, but it is the way of the future.
A battery enables you store the solar energy your roof panels are producing, so you can use it on a rainy day. A battery can also make you completely self-sufficient, providing enough energy for you to get ‘off-the-grid’. Batteries are expensive, but this is one area of solar technology that’s changing rapidly and prices will eventually come down.
Off-grid installations are being used in our area and they are increasingly more financially viable in instances where the cost of installing a new grid connection is prohibitively high. Enova partners with off grid experts who are very experienced in the custom design of off grid systems to give you the very best technical advice if this is what you want to achieve.
