You may not use all of the electricity that your Solar PV panels generate electricity throughout the day.
At the moment, it is not possible to receive payment for exporting excess electricity to the national grid. So, what can you do with the excess energy?
An ideal solution is to install a storage battery. These compact battery systems store excess electricity produced throughout the day, for use at night.
Battery storage allows you to make even more savings on your electricity bill.
A battery’s efficient lifetime depends on the technology and the way the battery is used. Manufacturers generally give an expected lifetime in years and/or in ‘charge-discharge cycles. We work with manufacturers such as Pylontech, Solarwatt, Sonnen and LG Chem.
There are two ways of linking a battery storage system into a Solar PV system – DC coupling, and AC coupling.
DC coupled batteries take power directly from the solar PV panels, and then feed the power to the inverter to be converted to AC when it is ready to be used.
AC coupled batteries are installed on the grid-side, where the solar PV’s DC has already been converted to AC. A separate inverter converts the AC back to DC for storing in the battery. When the battery discharges, the same separate inverter converts the DC back to AC.
This type of battery may allow other functions besides storing solar PV excess electricity, such as storing cheaper night rate electricity to use during the day.
The eddi water heater automatically diverts excess power to an immersion heater saving money on water heating costs. This is a very low cost solution, and will allow for further savings, especially if you have a well-insulated cylinder.
