Customer Testimonial
Richard ireland
The Thermo staff and installation team were most helpful and courteous as the old system was no longer operational. The team arrived on time and, despite the inclement weather, removed the old panels and installed the new, larger system in one day. I have been impressed by how sensitive the new system is in responding to a lack of sun. The final icing on the cake was Jade setting up the ability for me to monitor the inverter readings on my phone.

Which Type of Solar Companies Should You Avoid?
Choosing the right solar provider is important because a low upfront price does not always mean a good-quality installation. Be cautious of companies that:
✔ Make unrealistic savings or performance promises
✔ Pressure you to sign a contract immediately
✔ Do not clearly explain the total system cost
✔ Use poor-quality or unverified equipment
✔ Have unclear warranties or after-sales support
✔ Cannot provide proper installation and accreditation details
✔ Have repeated unresolved customer complaints
✔ Avoid giving a detailed written quote and system specifications
Always compare multiple quotes, check the equipment and warranties, and understand exactly what is included before making a decision.
