Do you export a lot of energy into the grid, that you could be storing in batteries to offset night use?
If not, the first step might be to upgrade your solar power system so that you have considerable surplus energy. Having more solar generation than you need can have a couple of extra benefits;
- It can help you to produce more on cloudy or rainy days to continue to meet your homes energy usage
- It can help you to charge your batteries quicker, when you have them. More solar panel production = Faster charging. This will again particularly help on cloudy days when there is limited solar power being produced.
How much electricity are you utilising a during night time hours?
This is the main reason for installing a battery. It allows you to store excess energy generated during the day and use it when needed at night. Or it can be used when there are cloudy or rainy days to reduce or eliminate the energy you currently buy from the grid during those times
