FAQs
What types of solar PV systems do you install in Whitwell?
We design and install three main categories of systems: (1) on-grid/“grid-tied” arrays that export surplus electricity to the grid and qualify for Smart Export Guarantee (SEG) payments; (2) hybrid systems that include a lithium-ion battery so you can store excess daytime generation for evening use; and (3) fully off-grid packages for properties without a reliable mains supply. All systems are tailored to your roof size, electricity usage profile and budget, and we only use MCS-certified panels, inverters and mounting hardware to ensure eligibility for incentives and building-control approval.
How much roof space do I need and what orientation is best for solar panels in Whitwell?
A typical 4 kW domestic array needs about 24–28 m² of clear roof with no significant shading between 9 a.m. and 3 p.m. South-facing roofs give the highest annual yield, but east- or west-facing pitches still achieve 85–90 % of a south-facing output, so they remain financially attractive. For flat roofs we mount panels on A-frames set at a 10–15° tilt to maximise production. During the free survey we measure usable area, run a shade analysis and produce a generation estimate backed by industry-standard PV*SOL software.
Will solar panels really work in Whitwell’s weather, and how much can I save?
Yes. Solar PV converts daylight, not just direct sunshine, so it produces electricity even on overcast days common in Derbyshire. A typical 4 kW system in Whitwell generates 3,400–3,600 kWh per year—roughly 70 % of an average household’s consumption. At current grid prices (≈30 p/kWh) you could offset £900–£1,000 annually, plus SEG export earnings of £100–£150. With zero VAT on residential installations and rising energy tariffs, payback periods are now 6–9 years, after which electricity is effectively free for the remaining 15–20 years of the panels’ lifespan.
How long does the installation take and will it disrupt my home life?
For most residential projects the scaffold goes up the day before, the roof-mounting and panel fitting take one full day, and the electrician completes the inverter, battery (if chosen) and consumer-unit connections on day two. We coordinate with you to switch off power for no more than 30–45 minutes while we make final grid connections and perform the MCS commissioning tests. All work is carried out by our own NICEIC-approved team, and we leave the site clean, remove all packaging and submit the Building Control notification on your behalf.
What warranties and after-sales support do you provide?
Our panels come with a 25-year performance guarantee (at least 84 % of rated output at year 25) and a 12-year product warranty. Inverters carry 10- or 12-year warranties, extendable to 20 years, and batteries are covered for 10 years or 6,000 cycles. We include a 2-year workmanship warranty backed by the Independent Warranty Association (IWA) and register every job on the HIES consumer protection scheme. Annual maintenance is optional, but we offer discounted inspection and cleaning packages to ensure peak performance.
Do you help with SEG registration, planning permission and financing?
Absolutely. We prepare and submit the G98/G99 grid-connection paperwork, issue the MCS certificate and guide you through registering with your chosen SEG provider for export payments. Most domestic installations in Whitwell are ‘Permitted Development’, so planning permission is not required; if your property is listed or in a conservation area we can produce elevation drawings and liaise with the council. For funding, we work with specialist green-energy lenders offering £0 deposit loans over 3–10 years, and we can integrate solar into a wider home-energy upgrade package if you are applying for ECO4 or Home Upgrade Grant support.
