# Commercial solar for Chemical & pharmaceutical manufacturing

Chemical and pharmaceutical manufacturers run clean rooms, process equipment, HVAC and controlled environments, often around the clock — a large, steady electrical demand. Funded solar and battery storage cut those costs and add resilience, with no upfront investment.

Precise, controlled production makes chemical and pharmaceutical sites highly energy-intensive: clean rooms, temperature and humidity control, process equipment and continuous HVAC create heavy, constant demand. Almost all on-site solar is consumed immediately.

With strict quality requirements and rising energy costs, a PPA is attractive — a lower fixed rate, no capital outlay, and battery storage that adds resilience for sensitive, controlled processes.

## Why it fits Chemical & pharmaceutical manufacturing

- **Constant, heavy demand** — Clean rooms and HVAC run continuously, so solar self-consumption is very high.
- **Resilience for controlled processes** — Battery storage supports power quality and helps ride through interruptions for sensitive production.
- **Meet sustainability requirements** — On-site renewables support the carbon reporting increasingly expected across pharma supply chains.
- **Own it if you prefer** — A PPA needs no capital, but hire purchase or outright purchase can suit firms wanting the asset and allowances.

## Frequently asked questions

**Can solar and battery support power quality for clean rooms?**

Battery storage helps manage demand and can support power quality and short-interruption resilience for controlled environments. We assess your critical loads and design accordingly.

**Is our roof suitable for a large system?**

Most pharmaceutical and chemical plants have substantial roof area, and the heavy constant demand means the solar is well used. We confirm suitability and structure in a free proposal.

## Funding routes

| Route | Upfront | Payment | Ownership | Maintenance | Accounting | Best for |
| --- | --- | --- | --- | --- | --- | --- |
| Power Purchase Agreement (PPA) | £0 | Fixed rate per kWh | Yours for £1 at end of term | Fully included | Off-balance-sheet (operating cost) | Businesses that want no capital outlay, no risk and no maintenance — just lower bills from day one. |
| Outright Purchase (CapEx) | Full system cost | One-off capital cost | Yours from day one | Optional O&M package | Capital asset | Businesses with capital available that want the strongest long-term return and full ownership. |
| Hire Purchase (HP) | Deposit | Fixed monthly instalments | Yours at end of agreement | Optional O&M package | Asset on balance sheet | Businesses that want to own the system but spread the cost and protect their cash flow. |
| Leasing (Operating / Finance Lease) | Low / none | Fixed rentals (opex) | Return, extend or buy at end | Optional O&M package | Rentals as operating expense | Businesses that want minimal upfront cost and predictable, tax-efficient operating payments. |

**Power Purchase Agreement (PPA)** — Zero upfront. Pay only for the clean power you use.

Pros: No upfront cost or capital outlay; Rate guaranteed at least 30% below the grid; Fully funded, installed and maintained for you; System becomes yours for a nominal £1 at the end.

Consider: A long-term agreement (typically 15–25 years); You don't own the system during the term.

**Outright Purchase (CapEx)** — Own it from day one and keep 100% of the savings.

Pros: Best long-term return on investment; Own the asset and keep every kWh of savings; May qualify for capital allowances / full expensing; No financing or interest cost.

Consider: Ties up capital that could be used elsewhere; You're responsible for maintenance (we can provide it).

**Hire Purchase (HP)** — Spread the cost, own the system at the end.

Pros: Preserve working capital — pay over an agreed term; Own the system outright at the end; Tax-efficient: claim capital allowances and offset interest; Fixed, predictable monthly payments.

Consider: Interest applies over the term; Subject to finance approval.

**Leasing (Operating / Finance Lease)** — Low upfront, predictable rentals as an operating cost.

Pros: Little or no upfront cost; Rentals are typically 100% tax-deductible; Predictable, fixed payments; Flexible end-of-term options.

Consider: You may not own the system at the end (depends on lease type); Subject to finance approval.
