Solar batteries for home energy storage
If you’re concerned your excess solar power energy is going to waste, then it may be time to think about getting a battery storage system installed. That’s exactly what we specialise in.
At Going Green Renewables, we’re passionate about making solar energy accessible for homeowners across Surrey and the UK. Our skilled technicians and affordable solutions offer everything you need to harness the sun’s power, from initial solar panel installation to solar battery storage systems that ensure maximum savings.
Our team will work closely with you to develop the perfect battery storage set-up to complement your existing solar panel system. We use only the best products, including lead-acid and lithium-ion batteries, that are known for their efficiency and durability.
Contact us today, and let us help you get the most out of your solar panel investment.
What are solar batteries?
A solar battery system allows you to take control of the energy generated from your solar panels and reduce the power you consume from grid electricity. Without battery storage, your solar system will generate electricity during daylight hours, and if the amount generated exceeds the power being consumed, then this energy is sent to the grid.
With a solar panel battery storage system, we can capture excess energy and store it for later use when power is required, reducing grid dependence and saving you money on energy bills.
We can install battery storage in your existing solar panel set-up as an AC-connected system. We can do this even if you have existing solar panels on FIT (feed-in tariff) payments. This won’t disrupt the power generated by your solar array and can be installed downstream from the solar inverter and FIT meter. This means you can keep receiving payments while making the most of your excess energy for self-consumption.
How do solar panel battery storage units work at home?
When we generate renewable electricity in our homes, the electricity is either used by the property or supplied to the national grid and used by other properties in the area. This helps lower energy bills somewhat, and the green electricity provided to the grid helps reduce the use of fossil fuels to generate energy, but it doesn’t maximise the self-consumption of solar power in our homes.
By installing a solar panel battery storage system, you can store any excess power generated on good days. This involves using a device to measure the power flow to your home. So, when power is detected flowing towards the grid, the battery will store the excess energy generated. Then, when power flows from the grid to your home, the battery will release the stored electricity. This ultimately reduces your grid energy use and helps you save money on growing electricity bills.
Do you need solar battery storage if you have solar panels?
You don’t need a battery storage system when you install solar PV. However, without batteries, the excess energy from the solar panels will be exported to the grid. Although this energy can receive payments under the Smart Export Guarantee (SEG), this is much lower than you’ll pay for electricity from your own energy supplier.
Our selection of solar battery storage systems for homes
We work with several battery manufacturers to ensure you get the best solar battery storage solution for your home. Each of our trusted manufacturers offers a variety of functions and benefits as listed below:
- Tesla Powerwall – This is an AC-connected battery that provides backup power, has a large capacity, and has excellent software. There is a new hybrid Powerwall 3 due for release this year.
- SolarEdge – These are primarily hybrid systems with a 10KWh capacity for single-phase systems and 4.6KWh for three-phase systems. The main benefits are solar edge optimisation, which allows maximum production from solar panels, and shade management. They have a good monitoring system and a family of storage devices, including smart plugs, hot water diverters, and EV chargers.
- Enphase – This is slightly different from other manufacturers as they are Microinverter manufacturers, offering panel-level optimisation and monitoring. They are a US company that prides itself on safety, reliability, software, and customer support. Their systems are easily expandable, and batteries come in 5KWh units.
- MyEnergi – These batteries come in units with a 5.0KWh battery capacity on a hybrid inverter and an entire family of products, including hot water diverters and EV chargers.

Frequently asked questions about home solar batteries
How many solar batteries are needed to power a house?
Every home is different, which is why we always assess properties before proceeding. Most systems are expandable, so if your energy use increases due to purchasing an EV or installing a heat pump, we can look to increase the size of the system later on.
How much does it cost to add a solar battery to an existing system?
The cost of a battery system will vary depending on the capacity required, which is measured in kilowatt-hours (KWh). Typically, most homes require between 5KWh and 10KWh, but this varies largely depending on the size of the PV system and the property’s consumption. This is why our process involves an initial call so we can better understand your home and energy needs. Call us today to get a quote for your solar battery storage system.
How fast do solar panels charge batteries?
On a good day of solar generation, a battery could be fully charged in as little as 2 hours, but on an overcast day, it could take all day and not be fully charged. We typically size the battery capacity with an inverter that can charge from zero to full within a 4-hour window so you can utilise the cheap overnight energy tariffs.
