Solar Panels in Oban, Argyll and Bute

A 3-4kWp system in Oban typically costs £5,000-£8,000 with 0% VAT included — the zero-rate VAT alone saves around £1,000 compared to the standard 20% rate. Based on Oban's solar yield of 792 kWh/kWp, a 4kWp system generates approximately 3,168 kWh/year, paying for itself in 6-8 years through electricity savings of £887+/yr and Smart Export Guarantee income of 4-6p/kWh. Adding a home battery (5-10 kWh) costs an additional £3,000-£6,000 and also benefits from 0% VAT. We recommend getting at least three quotes from MCS-certified installers to compare pricing and equipment.

Yes. A home battery (typically 5-10 kWh capacity) stores excess solar electricity generated during the day for evening and overnight use. This increases your self-consumption from around 30-40% to 60-80%, significantly reducing your reliance on grid electricity. Batteries currently cost £3,000-£6,000 and also benefit from 0% VAT on residential installations. Most batteries are warranted for 10-12 years and can be retrofitted to an existing solar system. Popular options include the Tesla Powerwall, GivEnergy, and Fox ESS units.

With a cost of £5,000-£8,000 (0% VAT included) and savings of £887+ per year based on Oban's solar yield of 792 kWh/kWp at current electricity rates of 28p/kWh, plus Smart Export Guarantee income of 4-6p/kWh for surplus electricity, a typical solar system in Oban pays for itself in 6-8 years. Argyll and Bute ranks #93 of 102 UK counties, and solar panels are still a strong investment here thanks to longer summer daylight hours and cooler temperatures that improve panel efficiency. After payback, you benefit from 17-22 years of near-free electricity as panels last 25-30 years. Adding a battery extends self-consumption and can reduce payback further if you use most electricity in the evenings. Total lifetime savings typically reach £15,000-£25,000 depending on your usage pattern.

Yes, solar panels generate electricity all year round, including during winter months. While output is lower from November to February, Argyll and Bute still receives usable daylight hours even in December, and panels work from diffused light on cloudy days. With 1,200 sunshine hours per year, the annual generation figure of 3,168 kWh for a 4kWp system in Oban already accounts for this seasonal variation. Cooler winter temperatures actually improve panel efficiency compared to hot summer days. Adding a battery allows you to store daytime generation for evening use when winter daylight hours are shorter.

A typical residential installation takes 1-2 days of on-site work. This includes erecting scaffolding, mounting the panels on roof brackets, wiring, inverter installation, and connecting to your consumer unit. The full process from initial survey to completed installation usually takes 2-6 weeks depending on installer availability and DNO requirements. Your MCS-certified installer handles the DNO notification (G98 for systems under 3.68 kW, G99 for larger systems) and all associated paperwork on your behalf.

Standard grid-tied solar systems shut down automatically during a power cut for safety reasons — this is to protect engineers working on the grid lines. Your panels will resume generating as soon as the grid power is restored. If you need backup power during outages, you can install a hybrid inverter with battery storage that isolates your home from the grid and continues supplying electricity from the battery and panels. This emergency power supply (EPS) feature is available on most modern hybrid inverters and is worth considering if you experience frequent power interruptions.

Yes. East or west-facing roofs still produce 80-85% of the output of a south-facing roof, making them well worth installing. Many installers recommend splitting panels across east and west faces to spread generation throughout the day, which can improve self-consumption and reduce the amount of electricity exported at the lower SEG rate. East-facing panels generate more in the morning, while west-facing panels peak in the afternoon — both align well with typical household usage patterns. Only north-facing roofs are generally unsuitable for solar in the UK.
