Frequently Asked Questions
Frequently Asked Questions
Are the 20% and 33% solar rules used for UK commercial planning?
No. The 20% and 33% figures you may see online are US roof-coverage heuristics or finance rules, not UK statutory commercial planning tests. UK planning decisions follow the Town and Country Planning (General Permitted Development) Order and local conditions, so assess your site against UK PD rights, roof type, visibility, and heritage status instead.
Do I need planning permission for solar on a commercial property in Manchester or the UK?
Not always. Many commercial solar installations fall under permitted development (PD), which does not require full planning permission, but PD is not automatic. Check whether your roof type, visibility, prior-approval triggers, or heritage status (listed buildings, conservation areas) push the project into full planning permission territory before sizing the array.
What is the difference between G99 and G100?
G99 is the DNO application to connect generation to the distribution network; G100 is the export limitation that ensures your site does not export beyond agreed limits. Both are DNO processes, and both can delay your programme if applications are mishandled.
What is the Smart Export Guarantee (SEG) for UK businesses?
The Smart Export Guarantee (SEG) is a UK scheme that pays businesses for surplus electricity exported to the grid. You must register with a supplier that offers an SEG tariff, and the rate varies by supplier, so tariff shopping matters for your export income line.
Should we install on-site solar or use a VPPA?
Install on-site solar when your roof or land is viable and you want direct bill savings and control. Use a VPPA when your site cannot host generation or you prefer a contract without capital outlay. A VPPA does not replace on-site generation if you have a viable roof; both can sit in a net-zero plan.
Why do some people remove solar panels, and does that apply to UK commercial sites in 2025–2026?
Panel removal stories usually involve poor design, roof issues, or mis-sold residential installations, not a systemic UK commercial problem in 2025–2026. The lesson for commercial buyers is to vet the installer’s survey thoroughness and financial assumptions before committing, not to avoid solar altogether.
How should we choose a commercial solar installer instead of a “top 3 companies” list?
Vet installers on G99/G100 experience, the quality of their financial assumptions, and survey thoroughness. A top-3 ranking does not tell you whether the installer can manage your DNO application or produce a model your board can trust.
What does Bee Solar’s free site survey and financial model include?
The survey covers roof and land suitability, the likely planning route, grid and export implications, and the inputs needed for the financial model. The model shows generation estimates, self-consumption vs export split, cost benchmarks, and a payback range, so you get board-ready evidence without guaranteed figures.
