Battery storage for solar panels

Provide over 70% of your electricity requirement using solar plus battery storage. And keep the lights on if the grid goes down...

Residential solar storage

Why install battery storage?

  • Grid independence: meet 70% of your annual electricity load with solar + storage.
  • Solar PV battery storage stores excess solar for later use.
  • Avoid peak time electricity costs: buy off-peak and store.
  • Standby: emergency lighting / power (optional).
  • Protect against rising electricity prices.
  • Reduce your carbon footprint.
  • Get paid to provide grid balancing services (> 50kW).
  • Off-grid solutions.

Which system?

The best all round residential solar storage product on the market is the Tesla Powerwall 2, a single unit system with a 5kW charger (7kW peak) and 13.5kWh of storage capacity. We are Tesla Powerwall Certified Installers.

We recommend the Powerwall 2 for several reasons:

  • Design and efficiency.
  • Quality control and safety.
  • 10 year warranty.
  • Lowest lifetime cost per kWh.
  • Beautiful design, wall hung or ground-mounted, and weather-proof.
  • Sized to allow off-peak charging as well as storage of excess solar.

Is the Powerwall 2 for you?

Sometimes our customers are looking for solar pv battery storage with less capacity, or bespoke, with increased UPS capability. As well as Tesla, we offer customised Victron based systems (ideal for off-grid), with a range of batteries including Simpli-Phi, LG Chem and Northstar TPPL lead.

Why choose Spirit?

We’re experts in battery storage systems. We’re also passionate about the technology and excited by the tremendous potential it offers to transform the way in which electricity is generated and distributed. We are technology agnostic; we continuously analyse the batteries and chargers available on the market to ensure we are offering our customers best-in-class technology.

It is very important that residential solar storage systems are sized to the time analysed loads of the property. Solar PV battery storage needs to be sized to take account of variability in solar output. We use in-house software to model both the electrical load and the charging and discharging behaviour of a battery system working in combination with solar PV. We will design a battery storage system, with or without PV, to minimise the lifetime cost per kWh of stored electricity. We recommend a home energy monitor / smart meter is installed to monitor the loads prior to sizing the system – click here for more information.

We have designed systems for back-up and off-grid applications and we are well aware of and compliant with the standards applying to power systems for essential services.

We don’t employ pushy salesmen – just technical people, passionate about energy efficiency - who will provide you with a system combining technical excellence and value for money. With systems typically lasting 15 - 20 years, we are here to support you and your system over the long term.

All projects are managed in house and installed by our in house installation team. We operate within a 60 mile radius of Reading, Berkshire.
