The detail — housing stock, planning, installer choice — is where this guide goes deep. 4kWp install £6,800–£9,800 Annual generation ~2,760 kWh Annual saving ~£540 Payback 14 yrs ## Is solar worth it in Lerwick? Solar is worth installing in Lerwick for most owner-occupiers with a south, east or west-facing roof of reasonable size — not because Scottish sunshine matches the south coast (it doesn't), but because Scottish module operating temperatures are cooler, Scottish electricity prices are high, and the Home Energy Scotland loan removes the cash-flow barrier. A 4kWp Lerwick install produces roughly 2,760 kWh/year — enough to cover ~45–55% of a typical Scottish household's annual electricity demand directly, with the surplus exported at 15p–30p/kWh under the Smart Export Guarantee. Where the case weakens: heavily shaded rear gardens, listed buildings where Listed Building Consent won't approve street-facing PV, or homes already heated entirely by gas with low electricity baseload and no plans for an EV or heat pump. Lerwick solar at a glance Sunshine hours/year 1100 Yield per kWp 690 kWh Typical 4kWp output 2,760 kWh/yr Estimated 25-yr savings £13,500 Solar suitability 2/5 ## Housing stock in Lerwick Shetland's solar payback is the longest in the UK — but unique summer 'simmer dim' (near-24-hour daylight in June) creates exceptional shoulder-month generation. **Predominant roof type:** Stone-built town centre, modern bungalows. ## Sunshine, irradiance and what to expect from Lerwick roofs Subarctic maritime climate; near-perpetual summer daylight balances low total sunshine hours. A typical south-facing 4kWp installation in Lerwick produces around **2,760 kWh/year** — enough to cover roughly 45–55% of a typical Scottish household's annual electricity demand (Scottish average ~3,400 kWh). With a battery, self-consumption typically rises from 30% to 65–75%. Estimated monthly generation — 4kWp in Lerwick Month Share kWh Notes January 2.5% 69 Low sun, short days February 4.5% 124 Ramp begins March 8% 221 Equinox lift April 12% 331 Strong shoulder May 14% 386 Long daylight June 15% 414 Peak month July 14% 386 Peak continues August 12% 331 Still strong September 8.5% 235 Autumn shoulder October 5% 138 Sharp drop-off November 3% 83 Low output December 1.5% 41 Winter minimum Modelled from PVGIS Scotland-region averages scaled to Lerwick's 690 kWh/kWp yield. May–August delivers ~55% of the full year. ## Lerwick solar prices and system sizing System size Indicative cost (2026) Annual saving Payback 3kWp (~7 panels) £5,304–£7,644 £405 14.4 yrs 4kWp (~9 panels) £6,800–£9,800 £540 14 yrs 6kWp (~14 panels) £9,180–£13,230 £756 13.4 yrs \+ 5kWh battery \+ £2,500–£3,800 \+ £180–£320 — ### What pushes a Lerwick quote up or down Two houses on the same street can see a 20–30% quote spread. The recurring drivers in Lerwick: - **Roof material.** Stone-built town centre, modern bungalows is common locally; that dictates hook type, drill time and whether flashings need bespoke fabrication. - **Storey count & scaffolding access.** A two-storey front elevation with a pavement licence typically adds £250–£450 over a single-storey rear job. - **Consumer unit age.** Pre-2015 boards often need a full changeover or a dedicated Type-A RCBO — budget £220–£420. - **Cable route length.** Long DC runs from a rear roof to a garage-mounted inverter cost £80–£160 in extra cabling and containment. - **Local installer density.** Highlands & Islands postcodes covered by 6+ MCS contractors typically quote 8–12% below single-installer areas. See our full [Scottish solar cost guide](/solar-panel-costs-uk) for line-item breakdowns and what to expect on the quote. ## Battery sizing for Lerwick homes A 4kWp system in Lerwick produces roughly 230 kWh in an average month — but most of it lands during daylight hours when households aren't home. Battery sizing is really a question of how much of that daytime surplus you want to shift into evening use: - **No battery.** Self-consumption sits around 25–30% (773 kWh used directly, 1,987 kWh exported at 15p under Octopus Outgoing Fixed). Simplest install, cheapest upfront, longest payback. - **5 kWh battery.** Self-consumption jumps to ~60% for a typical 2–3 person Lerwick household. Sweet spot for homes without an EV. Adds £2,500–£3,800; typically pays back in 7–9 years and eligible for its own £6,000 HES loan tranche. - **10 kWh battery.** Justified when there's an EV, a heat pump, or evening electric-heating load (common in older tenement and cottage stock). Self-consumption reaches 75–85%; pairs well with Octopus Flux where summer export prices exceed 30p/kWh. - **13 kWh+.** Rarely pays back in Lerwick — the summer surplus fills a 10 kWh battery by mid-afternoon anyway. Only worth it for whole-home backup or off-grid resilience. ## Choosing the right export tariff in Lerwick Once your system is commissioned and you have an MCS certificate, you can pick any UK Smart Export Guarantee tariff — you are not tied to your import supplier. For a 4kWp Lerwick system exporting around 1,380–1,932 kWh/year (battery dependent), the practical choice is between two Octopus tariffs: - **Octopus Outgoing Fixed (15p flat).** Best for households without a battery or with limited daytime flexibility. Predictable, easy to model — typical Lerwick export income £290–£248/year. - **Octopus Outgoing Flux (variable).** Best paired with a battery you can charge cheap and discharge/export at the 4–7pm peak. Well-set-up Lerwick households routinely earn £304–£431/year — but it demands active management. The rule of thumb: no battery → Fixed; 5 kWh+ battery and comfortable with an app → Flux. Switching between them is free and takes ~2 weeks. ## Solar companies and firms covering Lerwick Highly specialist market; very few quotes per enquiry. Lerwick-based contractors typically partner with mainland MCS holders for certification. The solar firms working in Lerwick fall broadly into three groups: established local electrical contractors who added PV, dedicated renewables specialists covering Highlands & Islands, and national installers who subcontract the roof work. Ask directly which of the three you are dealing with — it tells you who will actually turn up. A good sign in any Lerwick quote is that the surveyor has already checked your roof aspect and shading against real irradiance data rather than quoting a generic Scottish average. Anyone promising south-of-England yields on a Shetland roof is overselling. ### How to shortlist solar firms in Lerwick - **Check MCS certification first.** Search the MCS database by the ZE1 postcode to see which solar companies are genuinely accredited to install in Lerwick — certification is required for both the Home Energy Scotland loan and Smart Export Guarantee payments. - **Look for local roof experience.** Ask each firm how many stone-built town centre, modern bungalows roofs they have worked on in Shetland; the answer separates the specialists from the generalists quickly. - **Compare like for like.** Three quotes for solar panel installation in Lerwick should be judged on total installed price, panel and inverter model, warranty length and aftercare — not headline discounts. - **Verify consumer protection.** RECC or HIES membership gives deposit protection and an insurance-backed guarantee if the solar company ceases trading. - **Keep deposits sensible.** Reputable Highlands & Islands installers ask for 10–25% up front, with the balance on commissioning. If you would rather skip the research, we pass your details to just one or two vetted solar panel installers covering Lerwick — chosen for local reputation, not for who pays the most for leads. ## Shetland planning rules for solar Shetland Islands Council; rural and island HES cashback applies.

How long will scaffolding be up at my Lerwick property? For a straightforward 4kWp install on a two-storey Lerwick semi, scaffolding is typically erected the day before roof work, stays up for the 1–2 day install, and is dismantled 1–3 days after commissioning — 4–7 days end to end. Pavement licences (if the scaffold overhangs the public footway) add a 5–10 working day lead time via Shetland Council. 02. What ongoing maintenance will I need to do? Almost none. In Lerwick's wet-and-windy climate, natural rainfall keeps panels within 3–5% of peak output year-round. Budget for one visual inspection every 2–3 years (£80–£150), one inverter replacement at year 12–15 (£700–£1,400) and a battery replacement at year 12–15 if you fitted one (£2,200–£3,800). 03. Can I install solar myself in Lerwick? Technically yes on a single-storey extension or outbuilding, but you lose access to the Smart Export Guarantee, the Home Energy Scotland loan and every serious insurance product — all of which require MCS certification, which can only be issued by an accredited contractor. For any grid-connected install, self-installation is a false economy. 04. Is there a waiting list for solar installers in Lerwick? Lead times in Lerwick follow a seasonal pattern: 3–5 weeks from quote to install in October–January, stretching to 8–14 weeks between March and July when demand peaks. Booking a survey in autumn for a spring install is the single easiest way to shorten the wait. 05. What happens if my Lerwick installer goes out of business? MCS-certified installers in Lerwick are required to carry Insurance-Backed Guarantees (IBG) via HIES, RECC or QANW, which continue to cover workmanship for 10 years even if the company folds. Panel and inverter manufacturer warranties are also honoured directly by the manufacturer, not the installer. 06. How much do solar panel installers in Lerwick charge to fit a system? Installation labour and scaffolding usually account for £1,100–£2,000 of a Lerwick quote, with the remainder in panels, inverter, mounting and battery. That is why the total for a 4kWp install lands between £6,800 and £9,800 depending on which solar company you choose and how complex the roof is. 07. Can you recommend solar companies near Lerwick? We are independent, so we do not sell installations ourselves. We pass each Lerwick enquiry to one or two vetted MCS installers with the strongest local reputation and review record — never a shared lead list — so you get comparable quotes without repeated sales calls. 08. How quickly can solar panel installers start work in Lerwick? Lead times in the ZE1 area typically run 3–5 weeks from quote to install between October and January, and 8–14 weeks from March to July. Booking your survey in autumn is the simplest way to get solar panels fitted in Lerwick before the spring generation season starts. ## Other locations nearby [ Highland Inverness £580/yr · 11.8y payback ](/solar-panels/inverness)[ Highland Nairn £620/yr · 10.9y payback ](/solar-panels/nairn)[ Highland Aviemore £570/yr · 12.4y payback ](/solar-panels/aviemore) Keep reading - [→ Complete Scottish solar guide](/solar-panels-uk-guide) - [→ Solar panel costs broken down](/solar-panel-costs-uk) - [→ Are solar panels worth it in Scotland?](/are-solar-panels-worth-it-uk) - [→ Home Energy Scotland, ECO4 and SEG](/solar-grants-uk) - [→ The installation process step by step](/solar-installation-process) - [→ Maintenance & long-term performance](/solar-panel-maintenance-guide) Solar Advice Scotland Independent Scottish solar advice — costs, savings, Home Energy Scotland loans and trusted local installer guidance.
