Solar PV and Battery Storage

Solar PV and battery storage is a smart energy solution that lets you harness the sun’s power, cut electricity bills, and store excess energy for when you need it most. Instead of relying on the grid, you generate and use your own clean electricity—even at night or on cloudy days. With the UK’s Smart Export Guarantee, you can even sell surplus energy back to the grid, making your system work for you. It’s a cost-effective, eco-friendly, and future-proof way to power your home or business!

What is Solar PV and Battery Storage?

Solar photovoltaic (PV) systems use solar panels to convert sunlight into electricity. Battery storage allows homes and businesses to store excess solar energy for later use, rather than sending it back to the grid. This is particularly useful in the UK, where sunlight levels vary throughout the year.

How It Works

  1. Solar Panels Generate Electricity
  • PV panels absorb sunlight and convert it into direct current (DC) electricity.
  1. Inverter Converts Electricity
  • An inverter converts the DC electricity into alternating current (AC), which is used by household appliances.
  1. Energy Usage & Storage
  • The generated electricity is used to power appliances first.
  • Any surplus energy is stored in the battery instead of being sent back to the grid.
  1. Using Stored Energy
  • When solar generation is low (e.g., at night or on cloudy days), the battery releases stored energy.
  • If the battery runs out, electricity is drawn from the grid as usual.
  1. Grid Interaction
  • Homeowners can sell excess energy back to the grid through the Smart Export Guarantee (SEG), earning money from unused electricity.

Benefits of Solar PV and Battery Storage in the UK

  1. Lower Energy Bills
  • Reduces reliance on expensive grid electricity.
  • Allows you to use stored energy during peak price times.
  1. Energy Independence & Security
  • Protects against power outages and price increases.
  • Reduces dependence on fossil fuels and energy suppliers.
  1. Environmental Benefits
  • Cuts carbon emissions by using renewable energy.
  • Supports the UK’s net-zero carbon goals.
  1. Maximising Solar Energy
  • Ensures solar power is available even when sunlight is limited.
  • Reduces waste by storing and using more self-generated electricity.
  1. Financial Incentives & Increasing ROI
  • The Smart Export Guarantee (SEG) provides payments for excess energy fed into the grid.
  • The UK government offers reduced VAT on solar panel installations, improving return on investment.
