How SPI Domestic Renewable Energy Works
What our customers say
-
“Installing solar PV and battery storage has been a game changer for us. We already had an air source heat pump, but rising electricity prices meant our running costs were still a concern. Since the system was installed and properly set up to work alongside the heat pump, we’ve cut our grid electricity costs by around 70%, while keeping the house warm and comfortable all year round.
The advice and support throughout the process were excellent, from sizing the system to explaining how everything works in plain English. The installation was tidy, on schedule and caused minimal disruption. I now feel much more in control of our energy bills and far less exposed to future price rises. I’d happily recommend Justin and his team to any homeowner looking to pair solar and battery storage with a heat pump.”
-
“I’m absolutely delighted with the solar PV and battery system installed on my flat roof. From the first conversation through to commissioning, the service was professional, transparent and well organised. The team clearly understood the technical and design challenges of a flat roof installation and worked with great care to integrate the system neatly with the existing building fabric.
Performance has been excellent so far, with the battery significantly reducing my reliance on grid electricity and giving me much better control over my energy use. Communication throughout was first class, timelines were met, and the site was left tidy at the end of each visit. I would have no hesitation in recommending Justin and his team to clients and colleagues looking for a high‑quality solar and battery installation service.”

FAQs
-
Is my home suitable for renewable energy?
Most homes are suitable for renewable energy systems such as Solar PV and battery storage. However, every property is different, which is why a proper assessment is essential before installation.
During your assessment, we carefully review:
- Roof space, orientation, and shading – To ensure your system receives sufficient sunlight throughout the year.
- Electrical capacity and safety – Including consumer units, cabling, and compliance with current regulations.
- Existing heating systems – To determine suitability for technologies such as heat pumps or integration with solar.
- Your energy usage patterns – Understanding when and how you use electricity helps maximise system performance.
-
How much can I save with solar?
Savings from solar energy vary depending on several key factors, including system size, energy usage patterns, and electricity tariffs. Every building uses energy differently, which is why solar savings are never one-size-fits-all.
-
Will I need planning permission?
Most domestic solar installations fall under permitted development. We’ll confirm this for your property.
-
How disruptive is installation?
Renewable energy installations are typically completed within a few days and are planned to minimise disruption to your home and daily routine.
What to Expect:
Installation times can vary depending on the size and complexity of your system, including:
- The number of solar panels
- Whether battery storage is included
- Any electrical upgrades required
Most work is carried out externally or in plant rooms, garages, or utility areas, meaning disruption inside the property is kept to a minimum.
-
What about warranties and maintenance?
We use proven, high-quality equipment from established manufacturers, all backed by robust warranties to ensure long-term reliability and peace of mind.
While warranties vary by manufacturer and system type, typical coverage includes:
- Solar panels: Performance warranties of up to 25 years
- Inverters: Usually 5–10 years, with extension options available
- Battery storage systems: Commonly 10–15 years depending on usage
- Heat pump systems: Manufacturer warranties typically 5–7 years
We’ll clearly explain all warranty terms as part of your system proposal.
