What Affects the Cost?

Solar installation costs in Greenwich depend on system size (measured in kW), roof pitch and condition, property orientation, and shading from trees or buildings. Flat roofs typically cost more due to ballasted mounting requirements. Access difficulty, structural reinforcement needs, and whether battery storage is added significantly impact the final price. Material quality, inverter type (string vs microinverter), and installer reputation also influence costs. Greenwich's urban density can add labour complexity, particularly for terraced properties or those with restricted access.

Money-Saving Tips

Request multiple quotes to compare system designs and pricing. Consider a smaller 3–4kW system initially; you can expand later. Ask installers about available government grants, VAT exemptions, and feed-in tariff schemes. Schedule installation during less busy seasons (autumn/winter) for potential discounts. Ensure your roof is in good condition before installation to avoid future remedial work costs.

Frequently Asked Questions

What size solar system do I need for a typical Greenwich home?

Most 3–4 bedroom detached or semi-detached homes in Greenwich benefit from a 4–6kW system, generating approximately 3,500–5,500 kWh annually depending on roof orientation and shading. Terraced properties may suit smaller 3–4kW systems. A professional survey determines optimal sizing for your specific property and electricity usage.

Are there grants or funding available for solar panels in Greenwich?

Yes. The Smart Export Guarantee (SEG) pays you for excess energy fed back to the grid. Some properties qualify for ECO4 funding. Solar panels installed for energy purposes may benefit from VAT exemptions. Always check current government schemes and ask your installer about available incentives before installation.

How long does a typical solar installation take in Greenwich?

Most residential installations take 1–3 days depending on system size and roof access. A 4–6kW system typically requires 2 days. Larger systems, complex roofs, or battery integration may take longer. Your installer will provide a precise timeline during the site survey.

What maintenance costs should I expect after installation?

Solar panels require minimal maintenance. Annual or bi-annual cleaning (£150–£350 per visit) is optional but recommended in London's pollution-prone environment. Inverter replacement costs £1,500–£3,000 after 10–15 years. Most systems come with 25-year panel warranties and 10-year inverter warranties, minimising long-term costs.
