Finance large-scale commercial and industrial solar arrays from £80,000 to £2,000,000+, for warehouses, factories and distribution sites. HP, lease, or refinance
Yes, commercial solars are financed as a standard asset purchase, usually on hire purchase or a lease, with the machine itself acting as the security. UK prices typically run £80,000 to £2,000,000, and most deals are written over 12–84 months with a deposit of around 10–20%. Decisions typically take 24–48 hours. Used machines are financeable too, usually with a shorter term.

Guide prices for sizing a finance agreement, not quotes. Manufacturers in this market mostly price on application, so where a current UK list price could not be confirmed the row describes a specification class rather than naming a model. Your supplier quote is what the agreement is written against.

| Trina Solar Vertex S+ 505W | £150 – £220 per panel | Mono PERC Module |

Solar arrays of this scale generally qualify as plant and machinery for capital allowances, meaning a business can typically set some or all of the cost against taxable profits through the Annual Investment Allowance or other first-year reliefs. The exact allowance available depends on your company's overall capital spending in the year and current HMRC rules, so check with your accountant before finalising the finance structure.
At this scale, the typical buyer is a manufacturer, logistics operator or food producer with a large roof or spare land and a high, fairly constant daytime electricity load, since a big array is most valuable when most of the generation is used on site rather than exported. The investment case usually rests on offsetting a known, sizeable grid bill rather than a fixed payback promise; roof condition, structural survey, grid connection capacity and planning (for ground mount) are the main things that move cost and timeline, and are worth pricing before committing to finance. Retrofitting an existing roof is more common than new-build integration, and roof age is usually the first thing a surveyor checks.
Some specialist lenders consider businesses with imperfect credit histories. You may need a larger deposit or personal guarantee, but options may be available. Fundably may use a soft credit check for matching, which does not affect your credit score. A hard check may happen if you choose to proceed with a lender.
