Commercial & Industrial Solar PV Installations

Commercial & Industrial Solar PV. Designed Around Your Energy Profile.

At QUEST Electrical, we specialise in the design, installation, commissioning and maintenance of commercial and industrial solar PV systems designed to help businesses reduce energy costs, improve efficiency and generate their own renewable energy. As an experienced electrical contractor, we deliver complete solar solutions from initial assessment and system design through to installation, testing and ongoing support.

We primarily install SolarEdge solar PV systems, providing advanced monitoring, optimisation and energy management capabilities to maximise system performance. Our experienced engineers integrate solar PV installations with existing electrical infrastructure, ensuring systems are safely connected, fully compliant and designed around your business's energy requirements.

Whether you are looking to reduce electricity costs, improve sustainability targets, or future-proof your facility with renewable energy technology, we provide tailored solar PV solutions for industrial warehouses, factories and manufacturing facilities.

Case Studies

How a correctly designed commercial solar PV system is matched to a site's real energy profile.

48kWp solar PV installation at Albert Harrison, Meadway, Padiham

A 48.00kWp SolarEdge system using 96 x 500W DMEGC modules, an SE33.3K inverter and 48 x S1000 optimisers – modelled to supply around 45% of the site's annual electricity demand, with 76% of generation consumed directly on site.

View Case Study

Designed Around Consumption

46.09MWh estimated annual production

The array was sized against 77.36MWh of annual site consumption rather than maximising panel count, with modelled inverter clipping held to 0.08% and a 91% performance ratio.

Integrated with Existing LV Infrastructure

Switchgear, distribution and point of connection

Existing LV switchboards, distribution boards, protective devices and cable capacity are assessed before design, so the PV system is never treated in isolation from the installation it connects to.

Frequently Asked Questions

What is commercial solar PV?

Commercial solar PV systems generate electricity from sunlight, helping businesses reduce their reliance on grid electricity and lower energy costs.

Can QUEST design and install commercial solar PV systems?

Yes. QUEST Electrical provides commercial and industrial solar PV design and installation, from initial assessment and system design through to installation and commissioning.

Is solar PV suitable for industrial buildings?

Yes. Industrial solar PV can be particularly effective for factories, warehouses and large commercial buildings with significant daytime electricity demand.

How much can a business save with solar panels?

Savings depend on electricity usage, system size, available roof space and operating hours. A correctly designed solar PV system can significantly reduce the amount of electricity purchased from the grid.

Can solar PV be combined with battery storage?

Yes. Solar PV and battery storage can work together to store surplus energy generated during the day for use when solar generation is lower or electricity demand is higher.

How do I know what size solar PV system my business needs?

System size depends on your electricity consumption, available roof space, existing electrical infrastructure and energy requirements. QUEST can assess your site and design a solar PV system tailored to your business.
