battery storage

Daylight Energy are proud to be one of few companies in the UK approved to install the TESLA Powerwall battery storage system.

The first install in the UK of the long awaited TESLA Powerwall 2 AC. Installed by the renewable solutions company Daylight Energy Ltd. based in Dorset.

powerwall 2

Tesla’s latest home battery system that turns your home’s solar panels into an all day resource – increasing self-consumption of solar – while allowing backup in the event of an outage.

The Powerwall enables more of your home’s electricity use to come from solar, which enhances solar functionality, and reduces energy costs.

The Powerwall 2 is a fully-integrated AC battery system for residential or light commercial use. Its rechargeable lithium-ion battery pack provides energy storage for solar self-consumption, load shifting and backup power.

Powerwall’s electrical interface provides a simple connection to any home or building. Its revolutionary compact design achieves market-leading energy density and is easy to install, enabling owners to quickly realise the benefits of reliable, clean power.

Typical powerwall system

At its most basic, Lithium Ion storage is quite a simple concept, but involves some very high tech equipment. Here’s how it works using the Tesla Powerwall… 

  1. Solar panels convert sunlight to DC (Direct Current) electricity.

  2. Any surplus DC electricity charges the Tesla Powerwall.

  3. The inverter converts the DC electricity to AC (Alternating Current) for use in the home.

how it works

The Powerwall 2 responds to real time changes in home energy use, or can be configured to operate on a set schedule. When configured for self consumption, the Powerwall 2 will actively monitor solar production and home energy usage to autonomously charge and discharge to minimise grid consumption.

When solar panels produce more power than a home needs, the excess solar is sent back to the grid. The Powerwall enables a homeowner to capture and store excess solar energy produced during the day for use at night. The result is greater self-consumption of solar generation and reduced energy costs



Battery technology has come a long way in providing efficient storage solutions for domestic and commercial properties as part of an integrated PV system. The ability to store power generated throughout the day for use in peak demand periods is crucial in decreasing reliance on the grid and protecting against power outages.
