How to choose a solar panel installer

Choosing the right solar panel installer is crucial for UK homeowners looking to invest in renewable energy. A well-installed solar photovoltaic (PV) system can significantly reduce electricity bills and lower your carbon footprint, but the quality of the installation directly impacts its long-term performance and your peace of mind.

Why choosing the right solar panel installer matters

The benefits of home solar power

Installing solar panels on your home offers a clear path to generating your own clean electricity. This not only contributes to a more sustainable future but can also lead to substantial savings on your energy bills. With the average lifespan of solar panel modules often exceeding 25 years, and many systems continuing to generate electricity for 30-40 years, it's a long-term investment that pays dividends over decades.

Navigating the UK solar market

The UK solar market can seem complex, with numerous installers and technical considerations. The key to a successful solar installation lies less in the brand of panels and more in the expertise of the installer. Poor installation can lead to issues such as roof leaks, faulty wiring, or incorrect system sizing, which can impact performance and even void warranties. Therefore, understanding how to select a reliable and reputable installer is paramount.

Essential criteria for selecting a reputable installer

MCS certification and accreditations

The Microgeneration Certification Scheme (MCS) is the nationally recognised quality assurance standard for small-scale renewable energy installations in the UK, including solar PV. An MCS-certified installer ensures that both the products used and the installation practices meet rigorous industry standards for safety, performance, and sustainability. Without MCS certification, you may miss out on crucial government incentives, such as the Smart Export Guarantee (SEG). Always verify an installer's MCS status on the official register, rather than relying solely on claims on their website.

Experience and track record

Look for installers with a proven history and a strong portfolio of completed projects. An experienced installer will conduct a thorough site survey to assess your roof's suitability, considering factors like orientation, shading, and structural integrity. They should be able to provide case studies or examples of previous installations and references from other clients.

Comprehensive warranties and insurance

A robust warranty package is essential for protecting your investment. You'll typically encounter three types of warranties:

• Product warranty: Provided by the panel manufacturer, this covers manufacturing defects and material flaws, usually lasting 12 to 25 years, with some extending to 30-40 years.
• Performance warranty: Also from the manufacturer, this guarantees a minimum power output over a specified period, commonly 25 to 30 years, ensuring panels maintain a certain efficiency level as they age.
• Workmanship warranty: This is offered by the installer and covers the quality of the installation itself. MCS-certified installers must provide a minimum two-year workmanship warranty, though many reputable companies offer 5 to 10 years. An insurance-backed workmanship warranty offers additional protection if the installer ceases trading.

Customer reviews and references

Independent customer reviews and testimonials offer valuable insights into an installer's reliability and service quality. Look for a strong volume of reviews, as well as a high score, on platforms like Trustpilot. A company's responsiveness to both positive and negative feedback can also indicate their commitment to customer satisfaction.

Detailed quotations and site surveys

A reputable installer will provide a detailed, itemised quotation after a thorough site survey. This quote should clearly break down the costs of panels (brand and wattage), inverter (make and model), mounting system, scaffolding, electrical certification (including Distribution Network Operator (DNO) notification), and any other extras. Avoid quotes that offer a single lump sum without a clear breakdown, as these can obscure hidden costs. The quotation should also include an estimated annual generation figure in kWh, tailored to your property and energy usage, rather than relying on generic averages.

The solar panel installation process: what to expect

Initial consultation and design

The process typically begins with an initial consultation to discuss your energy needs, goals, and budget. This is followed by a site assessment, where a technician evaluates your roof's suitability for solar panels. Based on this, a system design is created, specifying the type and number of panels, inverter selection, and their placement.

Understanding planning permission

In most cases, domestic solar panel installations in England, Scotland, and Wales are considered 'permitted development' and do not require planning permission. However, specific rules apply if your property is a listed building or located in a conservation area. In such instances, you will likely need to seek planning permission and, for listed buildings, listed building consent. It's always advisable to check with your local planning authority to confirm any specific requirements.

Installation and commissioning

While the overall project timeline can span several weeks due to design, approvals, and scheduling, the physical installation of solar panels on your roof is surprisingly quick. For most UK homes, this typically takes one to two days. More complex installations, or those including battery storage, might extend to two days. Once installed, the system is tested, commissioned, and all necessary certification and handover paperwork are completed.

After-sales support and maintenance

Good after-sales support is vital for the long-term performance of your solar system. Enquire about maintenance plans, monitoring services, and how the installer handles any issues that may arise post-installation. While panels are generally robust, components like inverters may need replacing sooner than the panels themselves.

Maximising your solar investment with Fuse Energy

Once your solar panels are installed, Fuse Energy helps you get the most out of your investment. Fuse Energy does not install solar panels or home batteries; instead, it focuses on being the ideal energy supplier for solar-equipped homes.

Smart Export Guarantee and export tariffs

The SEG is a UK government-backed scheme that requires licensed electricity suppliers to pay small-scale low-carbon generators for the electricity they export to the National Grid. Only MCS-certified installations qualify for SEG payments. Fuse Energy provides smart tariffs designed to help you maximise your earnings from any excess solar generation you send back to the grid.

Optimising energy usage with the Fuse app

The Fuse app offers transparent tools to monitor your solar generation and home energy consumption. This allows you to manage your energy usage effectively, aligning it with periods of high solar output to maximise self-consumption and reduce reliance on grid electricity.

Navigating energy usage and tariffs, especially with a new solar installation, can sometimes raise questions. Fuse Energy offers round-the-clock human customer support to assist solar homeowners, ensuring you have ongoing assistance whenever you need it.

Common pitfalls to avoid when choosing an installer

Prioritising price over quality

Choosing an installer based solely on the lowest price can be a costly mistake. A cheaper quote might indicate lower-quality equipment, a lack of essential services, or an installer cutting corners on critical aspects like scaffolding or proper system design. The long-term performance of your solar system hinges on a quality installation, making it wise to invest in a reputable company.

Ignoring contract terms and conditions

Always thoroughly review the contract terms before signing. Pay close attention to what is included in the price, the specifics of the warranties, and any clauses regarding after-sales support or maintenance. Ensure all agreements are in writing and that you understand your rights and obligations.

Failing to understand system performance

A good installer will provide realistic estimates of your system's expected performance, taking into account factors specific to your property. Be wary of installers who make overly optimistic claims about energy savings or generation. Ask how they calculated the payback period and expected output, and query any projections that seem too good to be true.

Conclusion

Selecting a solar panel installer requires careful consideration beyond just the initial cost. By prioritising MCS certification, comprehensive warranties, transparent quotations, and a proven track record, UK homeowners can make an informed decision that secures a reliable and efficient solar energy system for years to come.
