With many homes in Bristol having solar panels on their roofs, a lot of electricity is generated but a lot of it is sent back to the grid for very little return. By using a solar battery storage system you can use the electricity that you have generated.
Raise Your Self-Consumption Rate
Without a battery, the average household using solar power to generate electricity will be able to use around 30-40% of the power that is generated. In contrast, when you use a battery to store excess energy generated by your solar panels during the day, you can raise your self-consumption to 70% or more. This is because instead of excess energy being sent to the grid for very little return, it is used to charge your battery instead.
Store Summer Surplus for Cloudy Days
The darker months of the year in Bristol are typically overcast so generation falls in the period from October to February. A battery charged up during the sunnier hours of the day and then used to power your home in the evening is a great way to use displaced grid power and cut your consumption. This could be on a daily basis or on those rare winter afternoons when the sun breaks through the clouds for a few hours and you get a top up charge.

Electricity from the grid is charged at its highest rate during the early evening hours (typically between 4pm and 7pm) and this is how the energy price cap is set to work. So by discharging your battery instead of buying electricity from the grid at these higher rates you will save money in the long run as peak avoidance adds up over the course of a year.
Pair With a Time-of-Use Tariff
There are also time-of-use tariffs that offer electricity at off-peak hours overnight for as little as 7p to 10p per kWh. Using your solar battery storage system to charge up from grid electricity overnight and then using the stored power to power your home during the peak tariff hours in the evening, even on the darkest of winter days when your solar panels are not generating any power, can result in significant cost savings throughout the year.

Track Import and Export Over Time
Most modern battery systems can log Import, Export and Self-Consumption. By viewing your numbers on a monthly basis you can see when you are most independent and also how by making small changes to the way your battery is set up to charge and also your daily habits can squeeze even more use from the power your solar panels are generating.
Small changes to the way your battery charges can have a big impact on how little you use the grid.
