Solar Battery Storage Saves You More!
Even the smallest of Domestic Solar Energy Systems can produce more energy than your home needs.
So, you have a choice whether you sell that energy back to the grid or store it in your home for later use. We would always recommend the latter, and not just because we want to sell you a battery, but because it will save you more money.
Energy produced by your solar energy system will always be cheaper than anything you buy from a supplier, so storing for later use is the most sensible thing to do.
You can even fit battery storage if you don’t have solar!

The advantages of solar battery storage
Use solar energy after dark
The most obvious advantage of battery storage for your solar system, is being able to store the energy your panels produce during the day. Then, after the sun goes down, and prices go up, you can use that lovely, clean electricity.
Take advantage of off-peak rates
The solar boom led to the creation of Energy Tariffs called SEGs (Smart Export Guarantee). These tariffs were created for customers to earn money from export, but they also offer different prices for imported energy depending on the time of day or demand. So, you can fill your battery storage when energy is cheap and use it when buying energy is expensive.
Lower your carbon footprint
The more of the energy you generate yourself, the less you are using from the grid. The power from your Solar Energy System is more or less carbon free, the power from the grid is a mix of green energy and not-green energy.
What is battery storage?
It’s exactly what it sounds like – large capacity batteries that will store energy until you are ready to use it.
Most domestic battery storage systems use Lithium-Ion batteries, which are efficient, safe and very cost effective.
With the increase in Electric Vehicles hitting the road, the demands for, and development of, Lithium-Ion batteries has come on in leaps and bounds – which has also had a beneficial effect on the solar industry.

Simply put, to save money. You will always save more by using any energy you generate rather than selling it. Having battery storage means you can use any power your solar panels generate after the sun goes down.
Years ago the answer to this would have been 'That depends how big your solar system is' but these days we'd say, get all you can! You can fill your battery using free power from the sun, or with cheap power from your supplier during off-peak hours.
We would always suggest you follow the manufacturer's guidelines on maintenance for individual installs. That said, solar batteries have no moving parts, come with a 5 -- 10 year warranty and need very little looking after. Your inverter app will help maintain your battery and keep it in good condition. More and more batteries are coming with their own apps too.
Solar batteries need to be close to your inverter so anywhere you can fit them both is the answer. The norm used to be a storage cupboard or your loft. Regulation is discouraging loft installations in the future though. Most modern solar batteries are IP66 rated, meaning they are weatherproof and can be stored outside.
This depends on the system you have, but most inverters allow you to add more than one battery. Not all inverters are compatible with all batteries, so make sure you choose the right kind of inverter if you wish to add batteries in the future.
As solar batteries aren't connected directly to the panels, the simple answer is yes! The inverter is the main controller in a solar system, and that is what the battery needs to be compatible with. Any solar panel will work with your inverter.
This really depends on what you buy, but most solar batteries come with a 5 - 15 year warranty, so you can expect that long out of them. When buying a battery always check the 'cycles'. A cycle is when a battery fully charges and discharges. The average solar battery has 6000 cycles, which is about 2 cycles every day for ten years.
You sure can! The grid produces more energy than we can use at certain times of the day. So, that energy needs to be stored somewhere. Energy companies are happy to sell that energy to customers at a reduced rate and buy it back when the demand is higher. SEGs, or Smart Export Guarantees, are used to facilitate this -- whether you have solar or not.
Why should you invest in battery storage?
Batteries range from 1 kW to 13.5 kW with the average 3-bedroom house home using around 8kW a day here in the UK – so fitting even the smallest battery will save you money.
A 4-kW solar energy system can, potentially, produce around 10 kW on a bright, sunny day. That’s more than enough to run the house, but a lot of that energy is produced when you’re not at home – so why not store it for when you are?
Your inverter will direct any excess energy to your batteries if it’s not being used in the home – or to the grid for export if you don’t have any batteries. The export will earn you pennies an hour if the energy is leaving the home at off-peak time, whereas you can use the energy in your batteries during peak times when you could be paying as much as 27p per kWh.
You can monitor your battery storage operation and optimise the charging cycles via the App for your inverter – so you don’t even have to be at home.
