SOLAR BATTERIES & POWER RESERVES
Retrofit solar batteries, also known as energy storage systems, are increasingly popular among homeowners and businesses seeking to reduce energy costs and achieve greater energy independence. These systems allow users to store excess solar energy generated during the day for use at night or during periods of low sun exposure. Retrofitting a solar battery into an existing solar PV system typically involves installing a battery unit between the system's inverter and the electrical grid. While this addition comes with upfront costs, it can provide significant long-term savings through reduced reliance on traditional utility providers and potentially even allow for off-grid renewable energy use. Battery technology has also advanced rapidly in recent years, offering systems with higher capacity, improved efficiency, and longer lifespans than earlier iterations. Anglia Solar offers retrofit options tailored to your specific solar PV system, making the process more accessible and user-friendly than ever before.

CAN I HAVE BATTERIES WITHOUT SOLAR PANELS?
We are very pleased to say yes.
Fitting batteries may be the simple answer. Fitting batteries will mean you need to have - or at least move to - a dual electricity tariff whereby you can enjoy, at much reduced night rate, cheaper electricity for a number of hours when you are asleep. Many utility companies offer such dual tariffs. This means you pay a higher price for each unit of electricity you use during the day but during the night a much lower rate when national demand is reduced. During these hours you can charge batteries or a power wall in order to draw on these reserve of cheap electricity during the day, instead of immediately drawing from the national grid at the normal higher priced electricity.
Example:
Day Rate: 53p per kWh Night Rate (during 5 hours per night): 14p per kWh
This represents a saving of 73+%
You can charge your own batteries overnight and they will be all ready to be used from when you get up.

HOME BATTERY STORAGE
Home battery storage systems, also known as residential battery banks, home battery systems, home battery backup or power walls, are an increasingly popular and a practical solution for homeowners who are looking to save money on their energy bills and reduce their carbon footprint. Home battery storage is a technology which allows homeowners to store energy generated by solar panels or wind turbines or simply from the grid during off-peak hours, and use it when they need it. This means that homeowners can rely less on the grid when electricity demand is high, reducing the need for expensive infrastructure upgrades and lowering overall energy costs. Home battery storage systems and residential battery banks are an increasingly popular and practical solution for homeowners which Anglia Solar supply and fit throughout East Anglia, Norfolk, Suffolk, Cambridgeshire and Lincolnshire. Home batteries in Suffolk have already dramatically reduced people's reliance on the grid and one customer had reported his home battery system in Norfolk when linked to his solar panels reduced his grid consumption by over 90% during the Spring, Summer and Winter months. This then leaves the Winter months when topping his home battery pack up over night with cheap-rate electricity allows him to enjoy a much reduced bill.
​
Another advantage of home battery storage is that it can provide a reliable source of backup power. In Norfolk, Suffolk, Cambridgeshire and Lincolnshire, we are able to fit extra technology which allows you to draw power from your batteries in almost all normal power-outage situations. In the event of a power outage, the Anglia Solar system can keep critical appliances and systems running, such as refrigerators, heating and cooling systems, and medical equipment.
​
Further, home battery storage has the potential to revolutionise the way we think about energy consumption and production. As more homeowners adopt this technology, there is an opportunity for a more decentralised energy system. This means that homes, businesses, and even communities can generate and store their own energy, reducing the need for large, centralised power plants and transmission infrastructure. In addition, with the right incentives, homeowners can sell excess energy back to the grid, helping to stabilise the electricity supply and lowering costs for everyone. Overall, home battery storage has the potential to create a more resilient, sustainable, and cost-effective energy system for everyone.
