Commercial Solar Panels Across Scotland

Yes. We can retrofit battery storage to an existing commercial solar PV system. Batteries allow you to store excess solar generation for use during peak rate periods and can also enable participation in grid flexibility services. Battery storage also qualifies for 0% VAT until March 2027.

Interest-free credit up to £30,000, subject to status. Any finance is arranged and provided by our authorised partners, not by Scottish Energy Efficiency. Contact us for details.

Call us on 0141 230 0198 or fill in our online form. We arrange a no-obligation survey of your premises, then provide a written, no-obligation quote covering system design, price, and timeline.

Yes. The UK government introduced 0% VAT on the supply and installation of solar panels and battery storage, effective from April 2022 until at least March 2027. This applies to commercial as well as residential installations. This relief applies to the full installation including panels, inverters, mounting, and labour.

A 50kWp commercial solar system in Scotland could generate an estimated 42,000–47,000 kWh per year, varying by roof and location. Every unit you generate and use on site is a unit you do not buy from the grid. Actual benefits depend on your consumption profile, roof orientation, and how much solar generation you self-consume versus export. Your survey quote shows estimated figures for your premises.

In many cases, rooftop commercial solar installations fall under permitted development rights and do not require planning permission. However, ground-mounted systems, installations on listed buildings, and projects in conservation areas will typically require planning consent. Systems over 50kW may also have additional planning considerations. We handle all planning applications as part of our service and advise on the requirements during the initial survey.

A G99 application is required for any solar PV system over 16A per phase (approximately 3.68kWp on single-phase). All commercial systems therefore require G99 approval from the local Distribution Network Operator (DNO) before commissioning. The G99 process involves submitting system design details to the DNO for assessment and approval. This can take 8 to 12 weeks. We manage the entire G99 application process on your behalf as standard.

Absolutely. Flat roofs are very common on commercial buildings and are well-suited to solar installations. We use ballasted mounting systems that do not penetrate the roof membrane, preserving your waterproof guarantee. Panels are typically tilted at 10 to 15 degrees on flat roofs, which provides good generation while minimising wind loading. Flat roofs also offer flexibility in panel orientation, allowing us to optimise the layout for your building.

Commercial solar systems require minimal maintenance. We recommend an annual inspection and performance review, plus periodic panel cleaning (typically every 12 to 24 months depending on the environment). Inverters should be checked annually for error codes and firmware updates. We offer commercial maintenance contracts that include annual inspection, performance reporting, cleaning, and priority callout for any faults. This helps maximise generation and lifespan.

Yes. Commercial solar PV installations qualify for the Annual Investment Allowance (AIA), which allows businesses to deduct the full cost of the installation from taxable profits in the year of purchase, up to the AIA limit. We recommend consulting your accountant for advice specific to your business.
