The Solar Solution
To meet the homeowner’s energy needs, we installed a 20-panel solar PV system (9.72kW) designed to make full use of the available roof space while delivering strong long-term performance.
System cost: From £10,495 fully installed
The installation included:
✔️ 1 elevation of scaffolding
✔️ FREE bird guard protection
✔️ Full MCS accredited installation
✔️ Complete DNO registration handled on the client’s behalf
✔️ Installation completed in just 48 hours
This system size is ideal for larger properties with higher electricity consumption. With 130m² of roof space available, the system was able to generate substantial renewable energy while keeping installation straightforward and cost-effective.
The Results
Annual electricity bill before solar: £1,800
Estimated annual saving and benefit: £2,443
This solar PV system doesn’t simply offset the household’s electricity usage. It also generates surplus electricity, allowing the homeowner to benefit from export payments through the Smart Export Guarantee (SEG).
This means the solar system effectively becomes a cash-generating asset, helping the homeowner earn back the cost of the installation while dramatically reducing reliance on the national grid.
What This Means for the Homeowner
Installing solar panels delivers both immediate savings and long-term financial benefits.
Key benefits include:
• Immediate reduction in monthly electricity costs
• Protection against future energy price increases
• Increased property value
• Lower household carbon footprint
• Long-term return on investment
With energy prices expected to remain volatile, generating your own electricity provides a level of financial security that traditional energy supply simply cannot offer.

Why System Size Matters
A 9.72kW solar system is particularly well suited to larger homes with higher electricity demand.
With sufficient roof space, these systems can:
• Generate significantly more electricity
• Reduce grid dependence even further
• Increase export payments
• Improve long-term system payback
For many homeowners, larger systems deliver the strongest long-term financial returns, especially when paired with battery storage.
Energy Security
With energy prices remaining unpredictable, homeowners who invest in solar today are effectively locking in predictable energy costs for decades to come.
A properly sized 9.72kW solar panel system on a 4-bed detached home isn’t simply an upgrade — it’s a long-term financial strategy.
And with MCS-approved installers, full certification, and compliance handled from start to finish, the process is simple, fast, and completely hassle-free.
