FAQs
How much electricity can a solar PV system in Cosby generate each year?
Cosby receives around 950–1,000 kWh of solar irradiation per square metre annually. A well-oriented 4 kW residential array will therefore generate about 3,400–3,800 kWh per year—roughly 70-90 % of an average UK household’s annual demand. Commercial roofs can scale up proportionally, with a 50 kW system producing roughly 43,000–47,000 kWh each year.
What financial incentives or savings are available for Cosby homeowners and businesses?
1. Smart Export Guarantee (SEG): Your energy supplier pays you for every surplus kWh exported to the grid (currently 4-15 p/kWh, supplier-dependent). 2. VAT relief: Until 31 March 2027 VAT on domestic solar, batteries and installation is 0 %, saving 20 % upfront. 3. Energy-bill reduction: Every kWh you self-consume offsets grid electricity priced at 25-35 p/kWh, typically cutting bills 50-70 %. 4. Accelerated Capital Allowances for businesses: Qualifying commercial installations can write off 100 % of the cost in year one, improving ROI. Typical simple payback in Cosby is 6-9 years for homes and 4-6 years for SMEs.
How long does the installation process take from survey to switch-on?
• Initial remote quote: 1-2 days after you send us your roof details or recent bill. • On-site technical survey: Usually within a week; takes about 90 minutes. • Design, DNO application & paperwork: 2-3 weeks. G98 systems (<3.68 kW per phase) require only post-installation notification; larger installations need pre-approval (G99) which can add 2-4 weeks. • Installation: A typical 4-8 kW domestic array is completed in 1-2 days; a 30-50 kW commercial job usually 3-5 days. • Commissioning & handover: Same day as installation completion. Overall timeline is commonly 3-6 weeks for small systems and 4-8 weeks for larger projects.
Will solar panels work during Cosby’s cloudy winters?
Yes. Modern monocrystalline panels with high-efficiency half-cut cells still generate electricity in diffuse light, albeit at lower output. Expect winter production to be ~15 % of your annual total in December-January and summer production ~35 % in June-July. Annual ROI calculations already factor in seasonal variation, and pairing the array with a battery (3-10 kWh) can raise self-consumption to 70-85 %, maximising benefits even on short winter days.
What maintenance is required and how long do the components last?
Solar PV systems are largely maintenance-free: • Panels: Tempered glass & anodised frames last 30-40 years; manufacturers give 25-year performance warranties (≥80-85 % output). • Inverter: Life expectancy 10-15 years; most warranties cover 10 years and can be extended to 20. • Battery (optional): 10-15-year lifespan with 6-10 k cycles; warranties usually 10 years/70-80 % capacity. • Cleaning: Rain keeps panels clear, but if your roof is shaded by trees or near bird roosts, a professional clean every 2-3 years is advisable. • Monitoring: Our online portal or app alerts you to any performance drop so issues can be resolved quickly.
Is my Cosby property suitable for solar, and what if my roof faces east/west?
Most south-facing roofs between 10° and 45° pitch achieve optimal yields, but east- or west-facing arrays still deliver 80-85 % of south-facing output—often worth the investment. Key suitability factors: • Roof size & shade: We need ~6 m² per kW; avoid chimneys or tall trees casting shadows. • Structure: We inspect rafters for sufficient load-bearing capacity (around 15 kg/m²). • Listed buildings & conservation areas: Planning permission may be required; we handle applications. • Flat roofs: Ballasted or elevated mounting frames provide 10-15° tilt. If roof space is limited, we can explore ground mounts or solar carports.
