Solar PV Installer In Guildford

System Sizes and What They Cost

We design solar PV systems to match your roof space, your electricity usage, and your budget. The three most common domestic system sizes are:

  • 3kW system (8 panels) Suits smaller homes or limited roof space. Generates approximately 2,400–2,800 kWh per year. Covers 50–60% of typical household consumption.
  • 4kW system (10–11 panels) The most popular size for 3–4 bedroom homes. Generates 3,200–3,800 kWh per year. The sweet spot between cost and output for most families.
  • 6kW+ system (15+ panels) For larger homes, households with high electricity usage, or those adding an EV charger or heat pump. Generates 4,800+ kWh per year.

See our pricing page for current system costs. We give fixed quotes after the free roof survey – no estimates, no hidden extras.

Battery Storage

Without a battery, surplus solar electricity is exported to the grid at a low rate – typically 4–6p per kWh under the Smart Export Guarantee. A battery stores that surplus so you can use it in the evening when you would otherwise buy electricity from the grid at 24–30p per kWh. This increases your self-consumption from a typical 30–40% to 60–80%, which dramatically improves the financial return on your solar investment.

We install three battery brands:

  • GivEnergy The most popular choice for UK homes. Excellent app, modular capacity (add more batteries later), and strong warranty. Our most recommended option.
  • Tesla Powerwall Premium brand with a large 13.5kWh capacity. Sleek wall-mounted design. Good for larger households with high evening consumption.
  • Fox ESS Competitive pricing with solid performance. A good option for budget-conscious installations where value matters most.

Solar and EV Charging in Guildford

If you have an electric vehicle or are considering one, solar and EV charging make an excellent combination. A Zappi charger can automatically divert surplus solar generation to charge your car during the day – free electricity from your roof rather than buying it from the grid at 24–30p per kWh. For a home with a 4kW solar system and a car on the driveway during the day, you could get 2,000–3,000 free miles per year from your roof.

We are both MCS certified for solar and OZEV approved for EV chargers, so we can design and install both as a single project in Guildford. This is more cost-effective than separate installations and ensures the systems work together seamlessly.

How Solar Installation Works in Guildford

The process from enquiry to generating electricity typically takes 4–6 weeks. Guildford is 20 minutes from our Church Crookham base.

  1. 1 Free roof survey We visit your property to assess the roof orientation, pitch angle, shading, structural condition, and available space. We also check your consumer unit and discuss your electricity usage. This takes about 45 minutes.
  2. 2 System design and quote We design a system to match your roof and your usage, and provide a fixed quote covering panels, inverter, battery (if required), installation, and all certification. We include an estimated annual generation figure and payback calculation.
  3. 3 Installation A typical domestic installation takes 1–2 days. Day one: scaffolding, roof mounting system, and panel installation. Day two: inverter, battery, electrical connections, and commissioning. We handle all the electrical work in-house – we do not subcontract.
  4. 4 Grid connection and SEG We handle the DNO (Distribution Network Operator) notification, connect the system to the grid, and help you register for the Smart Export Guarantee so you get paid for surplus electricity you export.
  5. 5 Certification We issue the MCS certificate (required for SEG eligibility), the Electrical Installation Certificate, and the EPC notification. All paperwork handled.

Solar Potential Across Guildford

Guildford is the largest town in our coverage area, about 20 minutes from Fleet. The residential suburbs around Merrow, Burpham, and Stoughton have properties with suitable roof space for domestic solar, and the commercial sector generates demand for commercial solar installations.

Merrow, Burpham, and East Guildford

The 1960s–80s housing has a mix of roof orientations. Many properties have south-facing rear sections suitable for 4kW systems. Good driveways for combining solar with EV chargers.

Onslow Village and Larger Properties

The larger Edwardian and inter-war houses around Onslow Village have substantial roof areas. These properties can accommodate 6kW+ systems and typically have the electricity consumption to justify larger installations.
