Store. Save. Sustain. – The Future of Energy Storage.
What it is
Battery storage refers to the technology that allows for the storage of electrical energy in a chemical form within a battery system, which can be converted back to electrical energy when needed. This technology is crucial for both residential and commercial applications, as it enables the storage of excess electricity generated from renewable sources, like solar panels, during periods of high production (such as daytime) for use during periods of low production or higher demand (such as nighttime or cloudy days).
Battery storage plays a pivotal role in the transition to renewable energy by mitigating the intermittent nature of sources like solar and wind. It ensures a consistent and reliable supply of electricity, even when the sun isn’t shining or the wind isn’t blowing. Additionally, it supports grid stability by providing services such as peak shaving, load shifting, and frequency regulation.
With over 1,200,000 domestic and commercial solar installations in the UK and soaring electricity costs, interest in maximizing self-use of our own free solar electricity is growing rapidly. Battery storage has also leapt forward through electric cars, commercial and home battery storage systems playing their key role in maximising local self-use and Grid balancing. Energy companies have accepted that Grid energy management needs storage when we have intermittent solar and wind power now providing over 40% of UK electricity generation.
We also see our cars and homes turning to electricity with 2.3M electric vehicles in the UK (June 2023) and our homes being encouraged to become electrically heated with the use of Heat Pumps. This logical progression is at last part of the Government’s Energy Strategy to wean us off fossil fuels. This approach has been the bedrock of Carbon Legacy’s objectives for the last 15 years. We have many examples of all electric Super Low Energy homes with measured results of 90% reductions in their energy bills from home solar generation and battery storage. Key to this has been the introduction of the Tesla Powerwall 2 home battery with its world leading reliability and software control.
With nearly 600,000 already installed across the World the Powerwall’s proven ability to be remotely managed by power companies such as Octopus Energy to “Grid Trade” solar power into the wholesale energy market. This turns the PV/home battery system into a mini power station that is both a financially attractive investment and provide protection against rising energy costs. We expect to see more innovative arrangements come to the market this year including the rumoured Tesla Electric power company.
We have revised our range to fit with both existing and new solar PV systems matched to the latest battery management and charger equipment from Tesla, Qcells and Dyness. Follow the links on this page to read more about Hybrid PV inverters, bolt on Battery management/charger systems and then contact us for a tailored solution for your home or building. Please remember it takes careful design, sizing, and selection of equipment to ensure you get a robust and reliable storage solution that will maximise your self-use of free solar electricity. Be wary of cheap batteries not designed for daily cycles of charging/ discharging with poor temperature control as this will lead to premature failure of your storage system.
