What Affects the Cost?

The primary cost drivers for solar installation in Farnham include system capacity (measured in kilowatts), roof type and condition, property age and accessibility, and whether integrated battery storage is required. Modern slate or tiled roofs typically cost more to work on than flat roofs. Properties requiring structural reinforcement, electrical upgrades, or planning applications add extra expense. Distance from the installer's base, property orientation, and shading from trees or buildings can also affect design complexity and final pricing.

Money-Saving Tips

Get three detailed surveys to compare pricing and system design. Consider a smaller 4kW system initially rather than oversizing your installation. Investigate government grants, SEG (Smart Export Guarantee) tariffs, and available tax incentives. Bundle installation with battery storage upfront for better package pricing. Choose installers offering MCS (Microgeneration Certification Scheme) accreditation—this unlocks customer protection and government incentive eligibility.

Frequently Asked Questions

What solar system size should I choose for a Farnham home?

A typical 4-bedroom Farnham house uses 3,000–4,000 kWh annually, making a 4–6kW system ideal. A detailed survey accounts for your roof orientation, current consumption, and budget. Undersizing means lower upfront cost but reduced savings; oversizing wastes money on unused capacity. Your installer will model your specific roof and usage.

Do I need planning permission for solar panels in Farnham?

Most residential rooftop installations in Farnham fall under permitted development and don't require planning permission. However, properties in conservation areas, listed buildings, or with planning restrictions may need approval. Your installer should advise before quoting. Permitted development rights simplify timelines and reduce costs.

How long does a solar installation typically take?

A straightforward 4–6kW residential installation in Farnham usually takes 2–3 days on site. Complex jobs involving roof work, structural upgrades, or battery storage integration may take 5–7 days. Weather, building control sign-off, and electrical testing can add time. Most installers schedule the work within 4–8 weeks of agreement.

What should I expect from a solar survey in Farnham?

A professional survey includes roof inspection, structural assessment, electrical compatibility check, shading analysis, and consumption review. The surveyor measures roof angle, orientation, and available space, then models energy production. Expect 1–2 hours on site. Most installers include survey costs if you proceed, or charge £150–£300 as a standalone fee.
