Investing Home Solar Panels: the Cost vs the Savings
Energy bills have risen significantly and solar panel costs have fallen. But is the investment in home solar panels worth it?
The 0% VAT rate on residential solar panels reduces the upfront outlay, and the Smart Export Guarantee pays you for every unit you generate and do not use. .
This means that for most well-designed home solar PV installations at current energy prices, payback periods fall in the 6 to 10 year range with a system lifetime of 25 years or more.
The financial case is strong. The bigger question is who you trust to install it. The domestic solar market contains a large number of businesses that are better at selling than installing, and that disappear once the job is done. SPI Renewables has been trading since 2009. We install systems, then we are prepared to continue to support you with our aftercare and maintenance services.

What Home Solar Panels Deliver for You
Lower Energy Bills
Export Income
Surplus generation that your household does not use is exported to the grid and earns Smart Export Guarantee payments. SPI helps you register with the most favourable SEG tariff at commissioning.
Energy Independence
What Makes a Good Home Solar Panel Installation
The quality of a solar installation is not visible from the outside. Two systems on identical roofs with identical panels can perform very differently depending on how they were designed, installed and commissioned.
SPI designs every home solar system around the specific property. Roof orientation, pitch, shading analysis, household energy consumption and the homeowner’s priorities all inform the design. We do not apply a standard package regardless of context. We produce honest generation projections based on your actual roof and local irradiance data, not industry averages adjusted to make the sale look better.
Installation is carried out by our own MCS-accredited engineers. We commission the system fully before we leave and set up remote monitoring from day one. If performance drops, we know about it. The aftercare relationship begins at installation, not ends there.
