Solar generates at around 6p per kWh across the system's 25 year life. UK business grid tariffs sit at 27p and have more than doubled since 2020. evon designs, installs, and monitors commercial solar so the lifetime cost advantage is yours from day one.

Commercial solar panels fix your generation cost for 25 years. You generate power on your own roof at a price you control, the same in year one and year twenty five.

UK business electricity has more than doubled since 2020, now around 27p per kWh, and it keeps climbing. Solar takes that volatility off your budget.

Every commercial solar PV installation is designed, installed, and commissioned by our own team. MCS certified, no subcontracted roof work.

The numbers work. Solar qualifies as plant and machinery, so 100 percent of the spend is deducted from taxable profits in the first year under full expensing. Most systems pay back in three to seven years, then run for the balance of a 25 year life.

Generation cuts your carbon emissions from day one and supports your ESG and net zero reporting.

Commercial solar delivered end to end.

evon delivers commercial solar installations across London and the South East. Every project is designed, installed, commissioned, and monitored by our own team. No subcontracted roof work. A single project manager on site from first survey through to handover.

Everything you need from one solar partner.

MCS certified, RECC member, NAPIT registered, and TrustMark endorsed. Every installation is certified and signed off to standard.

Designed, installed, commissioned, and monitored by our own engineers. No subcontracted roof work. A single project manager on site from first survey to handover.

We size the system to your consumption, not the roof area. Generation, on site use, and export are modelled before design freeze.

We design every system so battery storage can be added now or later. Capacity, inverter and cable routes are planned for it from day one, so adding storage is not a rebuild.

We manage the planning checks, the grid connection application and the structural sign off, so the project is cleared to proceed before we start.

A 25 year system life, a 10 year workmanship warranty, and an annual service visit included. When something needs attention three years in, you speak to the team that fitted it.

Accredited to the highest standard. Every project certified to the highest industry standards from design through to commissioning, signed off in-house by our own accredited team.

Recent solar projects.

From new build apartment blocks to architectural facades and workplace integration. A selection of evon solar installations across London and the South East.

Each project commissioned, signed off, and monitored by our own team. Test pack and MCS certificate handed over on day one.

Fix your power at 6p. The grid sits at 27p.

Commercial solar fixes your generation cost at around 6p per kWh for 25 years, while UK business grid electricity costs about 27p and rises year on year. The spread is yours to keep.

3 to 7 yr
payback

Most commercial systems pay back in three to seven years, then generate for the balance of a 25 year life.

100%
first year allowance

Solar PV qualifies as plant and machinery. Deduct the full cost from taxable profits in year one under full expensing.

Three ways to finance commercial solar.

We work across all three finance routes. Which one fits depends on your tax position, balance sheet appetite, and how long you intend to operate from the site. We run the numbers on all three at site survey. You decide.

Option 01

Outright Purchase

You buy and own the system outright. Fastest ROI of the three routes. Capital out day one, payback in three to seven years, net earning for the balance of the 25 year system life.

Option 02

Lease Agreement

Third party funds and owns the system. Typically no upfront costs. Fixed monthly lease below savings from month one. Asset transfers to you at end of term.

Option 03

Power Purchase Agreement

Third party installs, owns, and maintains. Zero capital outlay. You buy electricity at a fixed per-kWh rate below grid. Agreement transfers with the lease, so tenants can install without a capex event.

Six phases, end to end

We handle every stage from first site visit to lifetime monitoring. Single project manager on site, no subcontracted roof work, no handoffs. Six phases, all our own crew, with a fixed timeline at every stage so you know exactly what is happening and when.

Explore our six phases
Phase 01

Site Survey & Consumption Audit

We start with a roof structural assessment and review the last 12 months of half hourly MPAN consumption. Roof area, orientation, pitch, and shading are measured on site. You receive a scoped design, generation forecast, and indicative pricing within two weeks of first visit.

Phase 02

Design & Finance Proposal

The system is sized to your consumption profile, not your roof area. Generation, on site use, and export are modelled in detail. Payback is run across all three finance routes, outright, lease, and PPA, and you pick the route before design freeze.

Phase 03

Planning, DNO & Insurance

Planning permission checks and permitted development confirmation, DNO G99 notification for systems above 16A per phase, and structural loading sign off for the roof. Insurance assessment and project pack filing all complete before the install crew arrives.

Phase 04

Installation

Single project manager on site from start to finish. No subcontracted roof work. Our own crew, our own scaffolding. Access, deliveries, and works coordinated with site operations to minimise disruption. Typical programme runs 2 to 8 weeks by system size.

Phase 05

Commissioning & Handover

Full electrical test and MCS certification, G99 sign off, DNO notification filed. Handover pack with certificates, warranties, and single line diagram. Monitoring portal login provided so you can see generation from day one.

Phase 06

Monitoring & O&M

Continuous performance monitoring from day one of operation. Annual service visit included. Underperformance flagged and fixed under installer warranty. Generation data feeds straight into your SECR reports for the life of the system.

We are not tied to one brand. We select the right panels, inverters, and battery storage for your roof, your budget, and your generation target.

Installed, then looked after for life.

Every system is monitored from day one. We see underperformance before you do and fix it under warranty. When something needs attention three years in, you speak to the team that fitted it.

ROI

Are commercial solar panels worth it in the UK?

Commercial solar pays back in 3 to 7 years on sites with strong daytime consumption and 7 to 12 years on sites with lower daytime load. Systems generate for 25 to 30 years. Full expensing and VAT reclaim strengthen the short term position.

Cost

How much does a commercial solar installation cost?

UK commercial solar costs £700 to £900 per kWp installed. A 50 kWp system costs £35,000 to £45,000. A 200 kWp system costs £140,000 to £180,000.

Finance

What is a solar PPA and is it right for my business?

A Power Purchase Agreement lets a third party install and own your solar system at zero cost. You buy the electricity it generates at 20 to 40 percent below grid rates across a 15 to 25 year term.

Tax

Does commercial solar qualify for full expensing?

Commercial solar PV qualifies as plant and machinery under UK corporation tax. 100 percent of qualifying spend is deducted from taxable profits in the first year under full expensing.

Timeline

How long does a commercial solar installation take?

Physical install runs 2 to 8 weeks depending on system size and roof access. Planning, DNO notification, and structural sign-off add 4 to 12 weeks up front. Full programme typically 12 to 24 weeks.

Battery

Can we add battery storage later?

Yes. We specify every evon commercial system as battery ready by design. A hybrid inverter handles solar and battery on a single device. Adding storage later plugs in without a re-wire or inverter swap.

Maintenance

What maintenance does commercial solar need?

Modern commercial solar needs minimal maintenance. Annual inspections, occasional panel cleaning, and inverter servicing every 10 to 15 years. evon includes monitoring and an annual service visit on every install.

Performance

How much electricity will commercial solar generate?

A 100 kWp system in southern England generates around 90,000 kWh per year. Northern sites land closer to 80,000 kWh per year. Output drops 0.4 to 0.5 percent per year over the system lifetime.
