Battery Storage
What are the benefits of installing Battery Storage?
Use more of the electricity generated by your PV system
Store excess electricity and use it when you need it
Reduce your electricity bills
Won’t affect your Feed-in-Tarrif
Cut your carbon footprint
Sell excess energy back to the grid using the Smart Export Guarantee
Invest in the future and reduce your reliance on the National Grid
As an MCS accredited Battery Storage Installer we can advise you on the very best battery solution for your home or business. With a battery storage installation you can store your own renewable electricity to use later. You can also benefit from storing grid electricity when it’s cheaper to use at peak times. All of our works are backed by RECC, the Renewable Energy Consumer Code.
Why Battery Systems?
Battery storage allows you to make the most of electricity that you generate by storing it, so that you can use the energy when you actually need it. Battery storage can work alongside a solar PV system, whether retro-fitted to an existing installation or fitted as part of a new installation.
You could store more of the solar power that you generate so you can use it when the sun has gone down instead of drawing on grid electricity from your electricity supplier.
Storage is particularly useful and most valuable economically if you have solar but are out most of the day and can’t use all of your solar power but storage can also be used to draw power from the grid when it is especially cheap.
Battery systems can be grid connected without any other local generation sources, grid connected systems with other local generation or grid independent.
We will take time to understand your energy needs and patterns of use to propose the right storage solutions for you.
Positioning your battery
Batteries can be positioned almost anywhere in your property but an ideal place would be a garage, utility room or storage space where they are unlikely to get disturbed. Ideally we position batteries as close to the main tails and consumer unit as possible to enable communication and monitoring. Batteries can be positioned outside but will require an additional shelter, which we can provide.
Batteries and battery systems can vary considerably in shape, size and weight. The greater the battery capacity, the greater the battery size and weight. Typical domestic systems are around 400-600mm wide and 250mm deep and their height can depend on the number of modules and size of the storage.
Maintaining Battery Storage
A battery’s efficient lifetime depends on the technology and the way the battery is used – significantly on the number of complete full battery charge and discharge cycles that they undergo.
Manufacturers generally give an expected lifetime in years and/or in ‘charge-discharge cycles’. Lithium-ion batteries last longer than lead-acid: you may see a 10-year lifetime expectancy claimed and this is improving all the time. Normally the battery storage system will monitor the battery performance and should give you an indication when your batteries need replacing.
As solar panels can last 25 years or longer, your storage battery is likely to need replacing in the lifetime of your solar system.
Battery Storage systems can provide electricity in the event of a power-cut and can also be used to provide a dedicated supply for specific loads. Battery capacity is described in kilowatt hour (kWh). The size of the battery system that’s right for you will depend on your pattern of use and energy demands. We aim to design a Battery Storage system that achieves 80% self-sufficiency, significantly reducing your grid reliance whilst remaining cost effective.
