Top Reasons Kent Companies Are Investing in Solar

Across Kent’s diverse business landscape—whether in manufacturing, logistics, education, or retail—energy is a significant cost. Commercial solar  helps manage this by producing your own power on-site, insulating your operations from volatile energy prices and grid reliance.

1.    Immediate and Long-Term Cost Reduction

Commercial energy prices have soared, with the average rate for medium-sized users increasing nearly 70% between 2022 and 2024. A solar installation gives businesses long-term protection against rising energy costs .

For example, a 50 kW solar array can yield around 45,000 kWh annually, potentially saving £10,000 or more each year. Over 25 years, that equates to a six-figure reduction in operating costs—before factoring in export income or tax incentives.

2.    Stable, Predictable Energy Costs

Solar offers a buffer against fluctuating utility prices. When paired with battery storage, it enables you to store surplus power during the day and use it in the evening, when rates typically spike. With smart systems like Skygate™, usage can be automatically optimised—cutting peak-time charges and boosting ROI.

3.    Meet ESG Goals and Win Stakeholder Trust

Sustainability is no longer optional—it’s a key factor in procurement decisions, investor confidence, and long-term brand value. Businesses are increasingly expected to demonstrate measurable progress toward environmental goals, and solar energy offers a practical, high-impact solution.

A 50 kW commercial solar system can eliminate 15–20 tonnes of carbon emissions each year—the equivalent of planting more than 900 trees. These savings don’t just benefit the planet—they also strengthen your position in supply chains and tender processes that prioritise low-carbon partners.

4.    Ready for Electric Fleet Transition

With electric vehicle (EV) adoption accelerating in the UK, integrating solar-powered EV chargers on-site is a smart move. In 2024, EVs and plug-in hybrids accounted for nearly 40% of all new car registrations—a number set to grow as the 2035 ban on new petrol and diesel vehicles draws closer.

Solar-powered EV charging helps businesses cut vehicle running costs, reduce dependence on the grid, and stay aligned with evolving sustainability regulations and corporate goals.

Is Your Kent Site Solar-Ready?

Most commercial buildings across Kent—from industrial units in Maidstone to schools in Canterbury—are well-suited for solar. Here’s what matters most:

Surface Area and Angle

A 50 kW commercial solar system typically requires around 320 m² of usable, unobstructed roof space. This can vary depending on panel efficiency and layout, but it provides a solid baseline for planning. Flat or low-pitched roofs are not a barrier to solar—angled mounting systems can be used to position panels at the optimal tilt, usually between 30–40 degrees, to maximise sunlight capture.

For buildings where roof space is tight or partially obstructed by vents, skylights, or equipment, high-efficiency panels or split-array configurations can help maximise output within the available footprint. A professional site survey will determine the most effective design for your building’s structure and energy goals.

Roof Positioning and Sun Exposure

South-facing roofs offer the best conditions for solar generation, capturing the most consistent sunlight throughout the day. However, east- and west-facing roofs can still deliver strong performance—often achieving 80–85% of the output of a south-facing array when designed correctly.

Thanks to advances in panel efficiency and intelligent system design, many commercial properties in Kent with non-ideal orientations can still benefit significantly from solar. In some cases, combining east and west arrays can even extend energy production across more daylight hours, boosting self-consumption and reducing grid reliance.

Roof Strength and Condition

Each solar panel adds approximately 18–20 kg to the overall weight of the roof structure. While most modern commercial buildings in Kent are designed to support this load without issue, older or less robust roofs may need additional consideration.

In such cases, a structural survey is important to assess the roof’s load-bearing capacity and ensure the system’s safe installation. Upvolt includes this comprehensive survey in every commercial solar assessment, ensuring that your installation is both secure and compliant with all safety standards.

Do Kent Businesses Need Planning Permission?

For most rooftop commercial solar systems in Kent, planning permission is not required, provided certain conditions are met:

• Panels are installed less than 200mm from the roof surface
• The building is not listed or located in a conservation area or AONB (Area of Outstanding Natural Beauty)

Upvolt’s in-house planning team confirms permissions and handles all necessary paperwork on your behalf.

How Solar Installation Works for Kent Businesses

Upvolt’s turnkey service makes solar installation  simple and disruption-free. Here’s how the process typically unfolds:

1. Initial Consultation: A quick online survey or consultation to review your energy usage, building layout, and suitability for solar. This helps identify potential opportunities and constraints before a more detailed site assessment.
2. Technical Survey: An engineer visits your premises to examine roof structure, shading, layout, and grid connectivity.
3. Custom Design Proposal: You’ll receive a tailored system layout, cost estimate, and projected savings based on your site.
4. Installation: Once approved, installation typically takes 1–2 weeks, scheduled to minimise operational disruption.
5. Commissioning and Training: Your system is tested, connected, and linked to the Skygateâ„¢ platform, giving you live access to performance data, cost savings, and carbon reductions.

Solar System Costs for Kent Businesses

Prices vary based on roof complexity, system size, and whether battery storage is included. Here’s a typical pricing range:

Payback periods typically span 5 to 7 years, after which businesses can enjoy decades of free electricity and additional income from energy exports.

Financial Support and Schemes for Commercial Solar in Kent

Government incentives and tax reliefs  help reduce the cost of commercial solar installations significantly. Here are the key schemes available to Kent businesses:

• Annual Investment Allowance (AIA): Eligible businesses can deduct up to £1 million in capital expenditure, including solar panel installations, from their taxable profits, offering immediate financial relief. AIA is available to all businesses, including sole traders and limited companies.
• Full Expensing and 50% First-Year Allowance (FYA): Full Expensing allows limited companies to deduct 100% of the cost of qualifying solar equipment directly from taxable profits in the year of purchase. If Full Expensing isn’t applicable, businesses can claim the 50% First-Year Allowance on the cost, allowing them to deduct 50% of the cost upfront, with the remainder claimed through standard writing-down allowances.
• Solar Together Kent: A group-buying scheme that allows local businesses and households to access discounted rates (typically 10% and 25%) on solar panel installations and battery storage. Currently open for registration, businesses can register their interest and take advantage of this cost-effective way to adopt renewable energy when the scheme reopens.
• The West Kent Green Business Grant Support Scheme: This scheme offers financial assistance of up to 40% of the total project cost, with grants ranging from £5,000 to £8,000 depending on your business and project type. It helps businesses in West Kent reduce their environmental impact by supporting energy efficiency improvements, including solar panel installations.
• Smart Export Guarantee (SEG): If your solar system generates more electricity than your business consumes, you can sell the excess power back to the grid. Export rates range from 10p to 40p per kWh, depending on the supplier.

These financial incentives significantly shorten the payback period for solar installations and enhance their attractiveness, particularly for larger-scale systems.

Maintaining Your Solar Investment

Commercial solar systems are low-maintenance, but proactive care keeps them running at peak performance for decades.

Professional Cleaning

Over time, pollution, bird droppings, dust, and debris can accumulate on the surface of the panels, obstructing sunlight and reducing efficiency by as much as 10–15%. To maintain optimal performance, it’s recommended to clean your panels once or twice a year, particularly in areas with higher pollution levels or near trees and farms.

Annual Inspection

An annual inspection by a qualified technician is crucial for maintaining system integrity. This check ensures all wiring, mounting, and system components are secure and operating correctly. It’s also an opportunity to detect early signs of wear, corrosion, or other minor issues that, if left unchecked, could escalate into more significant problems, protecting your investment and minimising downtime.
