Choosing to go solar is a big step for any homeowner. It’s an investment that should last for decades and it deserves the same level of care you’d put into any major home upgrade. The challenge is that not all solar installers work to the same standard. Some cut corners, some oversell, and some simply don’t have the experience needed to design a system that genuinely works for your home.
At Sheerwater Solar, we’re often asked to fix or replace poorly installed systems, and the same mistakes appear time and time again. Here are the top five to avoid when choosing a solar installer.
A low price can be tempting, but it’s often a sign that something has been compromised. That might be cheaper panels, outdated inverters, a rushed design, or limited aftercare. A well designed system should be built to last, maximise output and be easy to maintain. Paying for quality up front usually saves far more in the long run.
Solar is a specialist field. Your installer should be properly accredited, trained and experienced in designing systems for UK homes. Many issues we encounter come from general contractors offering solar as a side service. A dedicated solar installer understands shading patterns, roof suitability, electrical integration and product compatibility in a way that protects your investment.
Every home is different. Roof angles, shading, energy usage and future plans all affect what your solar system should look like. If an installer offers a standard package without assessing your home in detail, that’s a red flag. A tailored design produces better performance, better efficiency and long term reliability.
Solar is not a fit and forget installation. You should know exactly who to contact if your inverter needs updating, if your monitoring stops working, or if you want to add a battery later on. Strong warranties and clear ongoing support show that an installer is confident in their work and committed to looking after you.
Real experiences from real customers tell you far more than a polished website. Look for installers with consistent, positive feedback and projects in your local area. A trusted name with proven results is often the difference between a smooth installation and years of frustration.
A great installer won’t just fit panels. They’ll design a system that suits your home, explain your options clearly, and be there long after the installation is complete. That’s the standard we work to every day at Sheerwater Solar.
