Installing Solar in Royal Windsor

Windsor presents unique opportunities and challenges for solar installations. As a royal borough with significant heritage, many properties require sensitive approaches - but that does not mean solar is off the table. Our experience in SL4 postcodes shows that premium all-black systems can complement even the most prestigious properties.

Windsor Solar Panel Costs

Premium property areas typically command slightly higher installation costs due to aesthetic requirements:

  • 3kW System: £5,800 - £7,000 - Suitable for period cottages near the river
  • 4kW System: £7,000 - £8,500 - Popular for Victorian terraces in the town
  • 5kW System: £8,200 - £10,000 - Ideal for larger homes in Clewer and Dedworth
  • 6kW+ System: £9,800 - £13,000 - For executive properties in Old Windsor

Conservation Area Considerations

Much of Windsor falls within conservation areas. Key considerations include:

  • Panel Aesthetics: All-black panels with black frames are essential for heritage settings
  • Roof Position: Installations on rear-facing or non-visible roof slopes typically require no planning permission
  • Listed Buildings: Properties near the Castle may need Listed Building Consent
  • Our Experience: We have completed numerous installations in RBWM conservation areas
