PV modules
Rail systems and mounting brackets
DC connectors, isolators and containment
Pro-Joy firefighter switches
Inverters and monitoring equipment
AC isolators, switchgear and metering
Unistrut frameworks and specialist roof clamps

All equipment is delivered to site with careful planning for logistics, rooftop access and safe handling.

Commercial Solar Installation

Our installation process follows strict safety protocols and industry-best practices. Your detailed scope is now fully included below.

3.1 Rails & Fixings

Rails are delivered to site in pre-cut bundles and lifted to roof-level storage areas.
Purpose-made brackets clamp directly to the standing seam roof to secure the rails to the structural steel frame.
Rails are spaced to allow two rails per row of modules, creating four secure fixing points per module.

3.2 Modules (Solar Panels)

Modules are delivered on wooden pallets and lifted to roof storage areas by Telehandler due to the absence of roof loading bays.
Each module is placed on the rails and secured using purpose-made clamps fixed to the rail channel with bolts and hand tools.
This process is repeated until the full array is installed. Module DC cables are plugged together using manufacturer connectors to form the required string layouts.

3.3 DC Cabling

Each module includes factory-fitted DC leads with industry-standard connectors. These are linked beneath the panels to create the required string configuration.
DC cables are secured neatly to the underside of the modules using clips and ties to prevent movement and abrasion.
Upon exiting the array, DC cabling is routed on a dedicated cable basket to the building entry point.
Inside the building, the DC cables are enclosed within dedicated trunking for protection and compliance.

3.4 Inverters, Firefighter Switches & Switchgear

Array strings are connected to firefighter switches, installed at appropriate locations.
DC cables are connected using MC4 plugs and terminated using calibrated crimping tools and cable cutters.
All DC terminations into firefighter switches and inverters are completed before final array connections, ensuring no high DC voltages appear in unconnected cables.
Inverters, isolators, meters, trunking and all switchgear are mounted on robust Unistrut frameworks using specialist roof clamps, nuts, bolts and hand tools.

Testing & Verification for Commercial Solar Installations

Before commissioning, our qualified testers complete a full suite of checks, including:

DC Testing

Open circuit voltage (Voc)
Short circuit current (Isc)
Insulation resistance
Polarity checks
Earth continuity

AC Testing

Dead and live tests in accordance with BS 7671
Functional checks for isolators, protection devices and shutdown systems

All isolations are locked off and verified. No live DC work is carried out except controlled testing via approved connectors.

Commissioning

Commissioning begins once the AC supply is fully installed and tested by the electrical contractor.
Dedicated PV string test equipment is used to record string voltage, current, irradiance, and panel/ambient temperature.
After DC testing is complete, the inverter is powered on and taken through its commissioning cycle.
Once configured, inverters are isolated and locked off until formal permission to energise is provided by ISG and the electrical contractor.

This structured approach ensures your commercial solar system is safe, compliant and performing exactly as designed.

Roof Protection Measures

We take great care to protect your building throughout the commercial solar installation:

Materials stored at roof level rest on wooden pallets or boards to distribute weight evenly.
Strict controls ensure no more than approved loads are stored in any one location.
Operatives take care when walking, transporting and installing components to prevent damage to the roof surface.

Protecting your asset is a core part of our service.

Documentation, Certification & Handover

Once installation and commissioning are complete, you receive:

As-installed drawings
Test results and commissioning records
PV module and inverter datasheets
Warranty information
NICEIC certification and MCS documentation (where required)
Operation & Maintenance manuals
Recommended maintenance schedules

This ensures your commercial solar system can be managed safely and effectively over its lifetime.

Commercial Solar Power – Frequently Asked Questions

What is commercial solar power?

Commercial solar power systems use photovoltaic (PV) panels to convert sunlight into electricity for buildings such as offices, retail units, factories, warehouses, schools, hospitals, hotels, and sports facilities.

They help organisations reduce energy bills, demonstrate sustainability, and support Net Zero goals across all sectors.

How much can my business save with solar panels?

Savings depend on your energy usage, roof or site size, and system design. Most organisations reduce their electricity bills by 40–70%. With energy costs rising, solar systems usually pay for themselves in 3–6 years, delivering decades of low-cost, renewable electricity.

We provide full ROI projections as part of every proposal.

Is my building suitable for solar panels?

Most buildings across all sectors are suitable if there’s enough unshaded roof or ground space and structural integrity. Typical installations include:

Flat or pitched roofs on offices, schools, hotels, or leisure centres
Metal, composite, or membrane roofs on factories, warehouses, or retail
parks
Ground-mounted arrays for logistics sites or large campuses

We offer free feasibility assessments to confirm structural suitability, generation potential, and expected savings.

Do solar panels work in the UK climate?

Yes. Solar PV panels generate electricity from daylight, not heat, so they perform efficiently even on cloudy days. Taunton offers excellent solar conditions, making them ideal for commercial solar installations.

How long does a commercial solar installation take?

From initial survey to commissioning, most projects are completed in 4–8 weeks.

Larger or more complex sites, such as manufacturing, logistics, or healthcare facilities, may take slightly longer due to operational considerations.

We manage the full process: design, supply, installation, testing, and grid connection.

What maintenance is required?

Solar PV systems require minimal maintenance. Periodic inspections and cleaning are recommended. Evans Electrical offers annual servicing packages, covering:

Visual and electrical inspections
Inverter testing
Output and performance monitoring

These ensure long-term efficiency and compliance with safety standards.

Can solar panels provide backup power during outages?

Standard grid-tied systems shut down during power cuts for safety. By adding battery storage or a hybrid inverter, your system can supply essential loads during outages — ideal for hospitals, hotels, and manufacturing facilities where uninterrupted power is critical.

Are there grants or incentives for commercial solar?

Yes. Available schemes include:

Smart Export Guarantee (SEG) – earn payments for surplus electricity exported to the grid
Annual Investment Allowance (AIA) – claim full tax relief on installation costs
Regional and sustainability grants – available in Taunton

We help identify and apply for the most relevant funding opportunities.

How long will solar panels last?

Commercial-grade solar panels typically last 25–30 years with minimal performance degradation. Inverters usually require replacement every 10–15 years. Our proposals include long-term maintenance and lifecycle planning.

Can solar integrate with EV charging and smart systems?

Yes. We design fully integrated energy solutions combining:

Solar PV generation
Battery storage
EV charging for fleets and staff
Smart monitoring and building controls

This helps organisations in logistics, retail, offices, hotels, and sports facilities reduce energy costs and carbon footprint.

Do you handle design, installation, and compliance?

Yes. Evans Electrical provides complete turnkey solutions, managing every stage from concept design and DNO application to installation, testing, and commissioning. Our engineers are NICEIC-approved and experienced across commercial, office, retail, manufacturing, industrial, logistics, education, healthcare, accommodation and hotels, and sports and leisure environments, ensuring compliance with BS 7671 and G99 standards.
