Smart Solar for a Farnham Home: Maximising ROI and Efficiency

Background:

Our client in Farnham wanted an energy-efficient, future-proof upgrade to their detached property. The homeowners travel frequently and needed a system that would not only reduce their carbon footprint but also work seamlessly when they are away from home. With a strong focus on maximising return on investment and remote control, we recommended an in-roof solar solution with smart energy storage and management.

Project Scope:

• Installation of 16 Solfit 425W in-roof solar panels
• Comprehensive roof refurbishment with new breathable membrane and battens
• Enphase IQ8 AC Microinverters for enhanced safety and efficiency
• GivEnergy All In One 13.5kW battery storage with AC coupled inverter
• Full integration with Octopus Energy for intelligent, automated energy use

‍Installation Process:

The project started with the roofing team stripping the existing roof. A new breathable membrane and fresh battens were installed to ensure the roof was level – a crucial step for fitting in-roof solar panels, as each panel clicks together to form a watertight seal.

Once the roof was prepared, we fitted 16 Solfit 425W in-roof solar panels. These panels are designed to integrate neatly with the roofline, offering excellent performance and a sleek aesthetic finish. For safety and maximum efficiency, every panel was paired with an Enphase IQ8 AC Microinverter. Unlike traditional systems, this design converts DC power to AC at the panel, eliminating the need for high-voltage DC cabling and making it one of the safest in-roof solar setups available.

To capture and store excess solar energy, we installed a GivEnergy All In One 13.5kW battery system with an AC coupled inverter. The battery stores any surplus energy after meeting the home’s immediate load, ensuring power is available even when the sun isn’t shining.

Smart Integration:

With the homeowners often away, it was essential their system could be managed automatically and remotely. Both Enphase and GivEnergy products partner with Octopus Energy, allowing remote control to switch between saving, storing, or exporting energy based on tariffs and usage patterns. This maximises the client’s return on investment while ensuring energy independence.

Results:

• 16 in-roof solar panels provide clean, efficient electricity all year round
• Enphase AC microinverters improve safety and optimise system performance
• GivEnergy battery storage maximises energy usage flexibility
• Automated control via Octopus Energy means the system works to save and earn money even when the homeowners are away
• The solar system can produce up to 5000 watts during peak times, and with the smart battery in place, the home often operates for a full day without drawing any power from the grid.
