If you are searching for a solar installer in Reading or across Berkshire, you want an installer that understands the technology, the regulations, and the real return on investment for your home. You also want an installer with a track record. Spirit Energy has installed thousands of solar panels across Reading, Wokingham, Earley, Caversham, Tilehurst, and wider Berkshire. Our installations range from small domestic rooftops to some of the region’s largest commercial solar projects.
Homeowners often find Spirit Energy by searching for solar battery storage installers near me, but they stay with us because of our engineering approach, our transparent design process, and our commitment to long term system performance.
Solar installation requires accurate surveying, shading analysis, and grid checks. We design each system using the same engineering tools we apply on large commercial projects, ensuring consistent performance for Berkshire homes.
Every home is different. Roof shapes, shading, energy usage, EV charging, and export tariffs all impact whether solar makes sense and how the system should be designed.
Our in house team handles everything from DNO applications to structural sign off and commissioning. Our design tools and specialist knowledge are the same ones we use on large commercial installations featured in our case studies. Read this blog to learn about every step of your solar journey with Spirit Energy.
Whether your priority is cutting bills, increasing energy independence, or preparing for electrification of heating and transport, our job is to build a system that performs for the next 25 years.
Battery storage is an important part of many solar installations in Reading, especially for homeowners who want to increase self consumption or protect themselves against power cuts.
That being said it is now a standard consideration for any homeowner installing solar. If you are searching for solar battery storage installers near me, the choice of installer matters even more than the choice of battery.
We have been installing battery storage for ten years, and we were the first company in the UK to install the Tesla Powerwall 3. We were involved in the development of the system, and our technical team produces some of the most detailed Powerwall content available in the UK.
Alongside Tesla, we install Sigenergy SigenStor. Why only these two?
• Both systems are high quality, long lasting, and supported by strong manufacturer warranties.
• They have predictable real world performance across a wide range of UK homes.
• Their software, safety features, and long term support exceed the standards of lower tier batteries.

Tesla has introduced a new rebate for Powerwall systems installed after 1 December 2025. The rebate is £375 per battery, including DC expansion packs. Homeowners can claim up to two rebates per property, giving a maximum saving of £750. The scheme runs until 31 March 2026.
This makes Powerwall 3 even more attractive for homeowners in Reading. A typical installation including the Tesla Gateway comes in at around £7,300 to £7,500 fully fitted. With the rebate applied, this drops to roughly £7,100. Powerwall 3 provides 15 kWh total capacity with 13.5 kWh usable, bringing the price to about £525 per kWh usable capacity. Removing the Gateway reduces the cost further.
Powerwall already compares strongly against competitor systems when you match usable capacity, power output, hybrid functionality, and whole home backup capability. With the rebate in place, the value proposition increases further.
