How to choose the right solar panel installer for your business

The UK has seen a surge in solar panel installations as homeowners and businesses look to cut energy costs and reduce their carbon footprints. However, choosing the right solar panel installer is crucial to ensure that your investment delivers maximum benefits. A good installer can mean the difference between years of hassle-free energy savings and ongoing issues with underperforming equipment. This guide will help you with the process of finding a reliable and skilled solar panel installer in the UK.
The importance of a quality solar panel installer
Solar panels are a long-term investment, with systems designed to last 25 years or more. While the panels themselves are important, proper installation plays an equally significant role in their performance and longevity. A professional installer ensures that the system is safe, optimally positioned for sunlight, and integrated seamlessly with your home’s electrical setup. Poor installations, on the other hand, can lead to electrical failures, roof damage, or systems that underperform, resulting in lost savings and costly repairs.
Additionally, quality installation is essential for claiming warranties and adhering to insurance requirements. Manufacturers often stipulate that their equipment must be installed by certified professionals. By choosing a reputable installer, you safeguard your investment and gain peace of mind.
Finding installers in your area
The first step in your search is to identify installers operating in your region. In the UK, you’ll find a mix of national companies and local specialists. Local installers often provide more personalised service and are familiar with the specific challenges and regulations of your area. For instance, they may have insights into common weather-related considerations or local council requirements.
You can start by searching online for solar installation companies near you. Websites such as the Microgeneration Certification Scheme (MCS) directory are excellent resources. Word-of-mouth recommendations are another reliable option. Business associates, friends, or family members who might know of a quality installer can sometimes offer valuable insights and recommendations based on their experiences.
Checking certifications and qualifications
Certifications are a key indicator of an installer’s professionalism and expertise. The Microgeneration Certification Scheme (MCS) is the gold standard for solar installers. Any installer operating under the MCS has been vetted for technical competence and adherence to industry standards. Choosing an MCS-accredited installer is essential, as many financial incentives, such as the Smart Export Guarantee (SEG), require MCS certification.
Beyond MCS, you might also look for accreditation from organisations like the Solar Trade Association (STA). These endorsements demonstrate a commitment to customer service, ethical practices, and ongoing professional development. Additionally, verify that the installer holds public liability insurance and employer’s liability insurance, which protect both your property and the workers involved in the project.
Assessing experience and expertise
Experience is a crucial factor when choosing a solar panel installer. Ask potential installers about their track record and the number of installations they’ve completed. An experienced installer is more likely to have encountered a range of challenges and will know how to handle site-specific issues such as shading, unusual roof structures, or limited space.
Make sure the installer has experience with the type of system you’re planning to install. For example, if you’re considering battery storage or an integrated solar roof, confirm that they’ve handled similar projects before. Additionally, enquire about their familiarity with well-regarded manufacturers, like SolarEdge, and their understanding of local weather conditions, which can impact panel positioning and performance.
Reviewing portfolios of past work
A reputable installer should be able to provide examples of their previous work. Reviewing portfolios can give you an idea of the quality and style of their installations. Pay attention to projects that are similar to your own in terms of property type, roof size, or system complexity. You may also ask for references from previous clients to hear about their experiences firsthand.
Powercor has several examples of large and complex solar installations.
When reviewing past work, look for signs of attention to detail. Neat cable management, well-aligned panels, and robust mounting structures are all indicators of a high-quality installation. Don’t hesitate to ask questions about how they handled specific challenges or customised solutions for unique situations.
Reading reviews, testimonials and awards
Online reviews can provide valuable insights into an installer’s reliability and customer service. Websites like Trustpilot, Google Reviews, and Which? Trusted Traders are good places to start. Pay attention to comments about punctuality, communication, and how the installer dealt with any problems.
While reviews can be helpful, it’s important to approach them critically. Look for consistent patterns in feedback rather than focusing on isolated comments. Be cautious of reviews that seem overly positive or negative, as these might not always be genuine.
Look to see if the installer has won any industry awards. While this doesn’t guarantee quality workmanship, it does imply that the installer is established in their industry with a strong reputation.
Understanding pricing and quotes
The cost of solar panel installation in the UK varies depending on system size, complexity, and location. When comparing quotes, look beyond the bottom line. A good quote should break down costs for equipment, labour, and additional services such as scaffolding, permits, or monitoring systems. It should also clearly state any potential extra charges.
Beware of quotes that seem unusually low, as these may indicate subpar equipment or rushed installations. Conversely, higher quotes may reflect the quality of the equipment being used – so it’s always worth enquiring further.
Evaluating warranties and after-sales support
Warranties are a critical component of your solar investment. A trustworthy installer should offer guarantees on both equipment and workmanship. Equipment warranties typically range from 10 to 25 years, covering the solar panels, inverters, and batteries. Workmanship warranties, on the other hand, protect against installation-related issues and usually last for 1 to 10 years.
After-sales support is equally important. Ask the installer about their approach to maintenance and whether they offer annual servicing. Knowing you can rely on your installer for future support adds an extra layer of security.
Assessing customer service
The quality of customer service you receive during your initial interactions can be a good predictor of your overall experience. A professional installer should respond promptly to your enquiries, explain their processes clearly, and answer your questions patiently. Look for companies that prioritise transparency and are willing to discuss potential challenges upfront.
Compliance with local regulations
In the UK, solar panel installations must comply with local council regulations and building codes. A good installer will handle compliance on your behalf, ensuring that all necessary permits are obtained and that your system adheres to planning requirements. This is particularly important if you live in a listed building or a conservation area, where additional restrictions may apply.
Pre-installation site assessment
A thorough site assessment is a crucial step in the installation process. The installer should visit your property to evaluate factors like roof orientation, shading, and structural integrity. This allows them to design a customised system that maximises energy generation while addressing any potential challenges. Avoid installers who skip this step or offer quotes without visiting your property.

Solar panels for business

Solar Panels for Business
With the world increasingly focused on sustainability and reducing carbon footprints, more businesses in the UK are turning to renewable energy solutions, particularly solar panels. Solar energy provides an excellent way to reduce energy costs, enhance sustainability credentials, and build resilience against fluctuating energy prices. For businesses of all sizes, from warehouses to office buildings, solar panels represent a smart investment for long-term efficiency.
In this article, we explore the benefits of installing solar panels for business, how they work, and what to consider when deciding if solar is right for your organisation.
Why Consider Solar Panels for Business?
As energy costs rise and environmental awareness grows, businesses are under pressure to find sustainable and cost-effective energy sources. Solar panels are one of the most viable solutions for the following reasons:
• Cost savings: Solar panels can significantly reduce energy costs by generating electricity on-site. Businesses with high-energy consumption, such as factories, warehouses, and sports stadiums, benefit the most, often achieving considerable savings within just a few years of installation.
• Energy independence: With solar panels, businesses can reduce dependency on the national grid and stabilise their energy expenses. This independence is particularly valuable in a market where energy prices fluctuate unpredictably.
• Sustainability and brand image: Companies that adopt green initiatives, such as solar energy, show a commitment to sustainability. This commitment can enhance brand reputation, attract environmentally-conscious clients, and demonstrate leadership in corporate responsibility.
• Financial incentives: The UK government offers various incentives and grants to encourage businesses to adopt solar energy. These can include the Smart Export Guarantee (SEG), which compensates businesses for excess energy they supply to the grid, potentially improving the return on investment for solar installations.
How Solar Panels work for Business Applications
Solar panels, also known as photovoltaic (PV) panels, convert sunlight directly into electricity. Here’s a basic overview of the process:
• Sunlight absorption: PV cells within the solar panels absorb sunlight, generating a flow of direct current (DC) electricity.
• Conversion to usable Power: An inverter converts the DC electricity into alternating current (AC), which is the form of electricity used by most businesses and appliances.
• Storage and usage: For businesses looking to operate around the clock, battery storage systems can be integrated to store excess energy generated during the day for use at night or during peak hours.
• Grid connection: If connected to the national grid, businesses can sell any excess electricity back to the grid, potentially earning revenue through schemes like the SEG.
The combination of solar panels and battery storage solutions can help many businesses achieve near self-sufficiency in energy, with minimal reliance on external electricity sources.
Advantages of Solar Panels for Commercial Properties
• Lower operating costs: Solar panels reduce monthly energy bills, allowing businesses to allocate saved funds to other priorities or to reinvest in energy efficiency upgrades.
• Enhanced property value: Commercial properties with solar installations often see an increase in property value. Buyers and tenants are increasingly willing to pay a premium for energy-efficient properties.
• Reduced carbon footprint: By shifting to solar energy, businesses can lower their greenhouse gas emissions, a vital factor in achieving the UK’s goal of net-zero carbon emissions by 2050.
• Long-term reliability: Solar panels have a long lifespan, typically 25–30 years, with minimal maintenance. For businesses, this means stable, predictable energy generation over decades.
• Flexibility for various business types: Solar installations are adaptable for many types of commercial properties. Large roof spaces on warehouses, offices, and retail centres can maximise solar panel installations, while even smaller businesses can benefit from compact or ground-mounted systems.
Key Considerations before Installing Solar Panels for your Business
Investing in solar technology requires careful planning and consideration. Here are key factors to take into account:
• Energy consumption patterns: Understanding your business’s energy needs and usage patterns will help determine the size of the solar system required. Businesses with high daytime energy consumption, for instance, can benefit more from solar as it aligns with peak production times.
• Roof space and orientation: The size and orientation of the roof on your commercial building affect solar panel placement and efficiency. South-facing roofs capture the most sunlight in the UK, but there are options for east-west facing installations that can capture sunlight throughout the day.
• Upfront costs and financing options: Although solar technology has become more affordable, the initial investment is still substantial. However, many financing options, such as leasing arrangements, power purchase agreements (PPAs), and government grants, can help manage costs.
• Return on investment (ROI): Solar panels typically have a payback period of 5–10 years depending on energy savings and government incentives. It’s essential to calculate potential savings and compare them to the upfront costs to ensure a positive ROI.
• Battery storage needs: Battery systems increase the ability to use solar power during non-daylight hours, which is crucial for businesses operating outside of typical daylight hours. Batteries do add to the upfront cost but can enhance energy independence and reduce reliance on the grid.
