Solar PV

Fully Certified Renewable Installer

Providing confidence in home-grown energy

Solar PV systems convert sunlight into electricity using photovoltaic (PV) cells. These cells are mounted on your roof and produce energy from daylight, not heat, making them effective even in the often cloudy UK climate. The electricity generated is converted from DC to AC by an inverter, which powers your appliances and lighting through your home’s fuse box. 

Any excess energy is automatically exported to the National Grid, ensuring no wastage. During periods of low sunlight or at night, you can still draw energy from the grid, keeping your home or business powered 24/7.

Investing in a Solar PV system with Greenfields not only helps lower your energy bills and carbon footprint but also provides long-term financial savings. Through the Smart Export Guarantee (SEG) and reduced reliance on grid electricity, homeowners and businesses can see a strong return on investment.

All government incentives require MCS-certified products and an MCS-approved installer—Greenfields meets both criteria, ensuring you can take full advantage of these financial benefits.

  1. Smart Export Guarantee (SEG)
    • Generation Savings – By producing your own electricity, you reduce the amount purchased from the grid, leading to lower energy bills.
    • Export Tariff Payments – If your system generates more electricity than you use, the surplus is exported to the grid, and you receive a payment per kWh exported.
  2. Energy Bill Savings
    • By generating your own electricity, you become less reliant on energy suppliers, reducing your exposure to rising electricity prices. The savings depend on your energy consumption, system size, and SEG rates, but homeowners typically see a substantial reduction in bills over time.

A 4kW Solar PV system costing around £5,500 could generate approximately £900 per year in combined energy savings and SEG payments. This means a payback period of approximately 6 years.

The exact ROI will vary based on energy usage, SEG rates, and system efficiency, but Solar PV remains a financially attractive investment for both residential and commercial properties.

We understand that installing Solar PV is a significant financial decision, which is why many of our customers choose to finance their system through loans or financing plans. This allows you to spread the cost while still benefiting from the long-term savings and financial returns that solar energy provides.
