100kW Factory Solar Installation, Greater Manchester

Greater Manchester

Manchester Renewables installed a 100kW commercial solar PV system on a large factory roof in Greater Manchester. Rows of panels run the full length of the building, taking advantage of the expansive flat roof to deliver one of our bigger industrial installations.

At 100kW, this system is estimated to generate around 85,000 kWh of clean electricity per year. For a factory running during daylight hours, that represents a serious dent in the electricity bill — with most of the energy consumed on-site rather than exported to the grid.

Larger systems like this benefit from economies of scale, bringing the per-kW cost down and improving the return on investment. Combined with Enhanced Capital Allowances, the business can deduct the full cost from taxable profits in year one, making the net investment even more attractive.

Common Questions

How much does a 100kW commercial solar system cost?
A 100kW system typically costs between £75,000 and £95,000. Larger systems benefit from economies of scale, often coming in below £900 per kW installed. Most factories see a return on investment within 3-5 years.
How much roof space does a 100kW system need?
A 100kW system requires approximately 500-600m² of roof space depending on panel efficiency and mounting angle. Most medium to large factory roofs have more than enough space.
Can I add battery storage to a factory solar system?
Yes. Battery storage allows you to store surplus solar energy for use during evenings, early mornings, or cloudy periods. It can also help reduce peak demand charges. We can design a combined solar and battery system tailored to your usage pattern.
What happens to excess electricity my factory doesn't use?
Surplus energy is exported to the grid. Under the Smart Export Guarantee, you earn a payment for every kWh exported. However, we size systems to maximise self-consumption — using the energy on-site is always more valuable than exporting it.
