Mid 2016, Lightsource and EDF Energy joined forces to create a revolutionary renewable energy system and storage system, easily tailored to suit many types of home. This partnership, one of the first of its kind in the UK, combined innovative financial structures with groundbreaking monitoring technology to bring distributed generation to homeowners across the country. Lightsource Labs, a newly formed research and development arm of the company, are constantly working on this and may other projects to advance the solar revolution and change the face of the global energy market.

The solution born of the partnership, named Sunplug, combines solar PV with battery storage and a smart monitoring system, giving customers much more control over their home’s electricity, and the ability to reduce their bills and carbon footprint. Adding storage to residential solar means that more people than ever will be able to generate clean electricity for their homes – gone are the days of having to be at home all day to get the most out of solar.

The lack of storage capabilities in traditional systems meant that solar was rarely a good option for anyone who wasn’t at home during the day – the panels were generating loads of cheap, clean power that the household couldn’t use, because they were busy out and about. As soon as the sun went down, they’d have to run their appliances on expensive grid electricity instead. By introducing storage to solar, Sunplug is changing all that. Adding Sunplug to a home means the household can store their own clean energy to use during peak tariff times, reducing the need to purchase expensive grid electricity and cutting bills even further.

Essentially, the Sunplug solution offers homeowners greater control over their energy consumption. Combining a cutting-edge home battery with an innovative online app, customers can store excess solar electricity for later use, while monitoring how much energy is being generated, used, stored or exported to the grid in real time. Homeowners with Sunplug can generate up to 88% of the electricity consumed by their homes using their solar panels. Sunplug allows customers to understand their energy usage patterns, giving them the chance to make positive behavioural changes to reduce their electricity consumption, inevitably money on their bills.

The solution comes in two different formats: Sunplug Complete and Sunplug Battery. With Sunplug Battery, customers who already have an existing solar PV system can boost the efficiency of their panels with storage and monitoring technology. Sunplug Complete offers customers two ways to get a cutting-edge solar PV system for their home, either having the system installed at no upfront cost and being billed only for the solar electricity they use, or buying the system and receiving the solar electricity for free.
