Frequently Asked Questions
Are solar panels worth it in Grantham?
Yes. With electricity prices significantly higher than in previous years and typical returns of 15-20%, solar outperforms most investment options. Grantham receives similar sunshine hours to the wider East Midlands, typically generating around 900-1,000 kWh per kWp installed. Systems commonly pay back in 4-7 years (business) or 6-8 years (domestic), then provide 20+ years of substantially free electricity.
How long does installation take?
Domestic installations typically complete in 1-2 days; commercial projects take 1-4 weeks depending on scale. The full process from enquiry to working system is usually 4-6 weeks, including surveys, DNO applications, and installation.
Do I need planning permission in Grantham?
Most installations fall under permitted development - no planning permission needed. You may need approval if your property is listed, in a conservation area (such as parts of Grantham's historic centre), or if panels project over 200mm from the roof. We handle all planning applications through South Kesteven District Council where required.
Can I get grants for solar in Grantham?
Yes. Businesses can access regional energy efficiency grants and capital allowances. Homeowners benefit from 0% VAT (saving thousands), Smart Export Guarantee payments (5-15p/kWh), and potential ECO4 funding. We help identify and apply for all available funding.
Do solar panels work in cloudy weather?
Yes. Modern panels generate electricity from daylight, not just direct sunshine - producing 10-25% capacity on overcast days. Panels actually perform better in cooler temperatures than in extreme heat, making the UK climate well-suited to solar generation.
