FAQ

Need Help? RoboMo's Got Answers

How much does commercial solar cost per kW?
DESNZ's 2025/26 data puts non-domestic 10–50 kW systems at a mean of £1,167.29 per kW of installed capacity, across 5,163 installs in Great Britain. DESNZ publishes no band above 50 kW, so larger systems are priced on quotes.
Do I need planning permission for solar on a commercial roof?
Often not in England. Class J of the GPDO allows roof solar on non-domestic buildings within height and edge limits, and the old 1 MW cap was removed in December 2023. Systems over 50 kW need prior approval from the council first. Listed buildings and scheduled monuments are excluded.
Can I put solar canopies over my car park?
In England, Class OA permits solar canopies over non-domestic off-street parking up to 4 m high, at least 10 m from homes, after prior approval of siting, design and glare.
Does my business system need a G99 application?
Almost certainly. G98 only covers up to 16 A per phase. Above that, the installer applies to your DNO under G99 before installation, sometimes through the fast track.
What if the grid cannot take all my export?
An export limitation scheme built to EREC G100 can cap export to what the DNO allows. The scheme must be fail-safe, and it is applied for alongside the G99 forms.
Can a business get paid for exported solar electricity?
Yes. The Smart Export Guarantee covers solar PV up to 5 MW in Great Britain. Suppliers set the rate, which must be above zero, so compare offers.
What is a solar PPA?
A power purchase agreement in which a third party owns and runs the system on your site and you buy its electricity at an agreed price. Kilowatts compares installation quotes and makes no recommendation on PPAs.
Does Kilowatts install commercial solar?
No. Kilowatts UK is a comparison service; independent partner installers survey, price and install, and you contract with the one you choose. Commercial quotes are available UK-wide.
