Frequently Asked Questions
What Are Solar PV Spares?
Solar PV spares are the replacement parts and supporting equipment used to service and maintain solar systems. They include components such as temperature sensors, which measure heat within the system, alongside diagnostic tools that help installers check performance and pinpoint faults. Sourcing the correct spare keeps a solar installation running accurately and efficiently, and helps restore reliable operation during servicing and repair.
What Products Does City Plumbing Stock in This Category?

- REMS ThermoCam 28 C Set (176030 R4) – a thermal imaging camera set at £990.00 inc. VAT
How Do I Choose the Right Solar Temperature Sensor?
The correct sensor depends on the solar system you are working on and the part you need to replace. It helps to weigh up a few points:
- System make and model – match the sensor to the appliance, as parts are often brand-specific
- Part number – for a like-for-like replacement, the existing part number is the most reliable guide
- Sensor type – confirm the sensor suits the position and function within the system
- Brand – Grant is a trusted name in the trade for dependable renewable spares
If you are sourcing a direct replacement, always check the original part against the system before ordering.
What Is the REMS ThermoCam Used For?
The REMS ThermoCam 28 C is a thermal imaging camera set used to detect and display temperature differences across a surface or system. It gives installers a clear, visual way to identify heat patterns, spot cold spots, and locate faults that are not visible to the eye. On solar and wider heating work, this makes it a valuable diagnostic tool for checking flow, tracing pipework, and confirming that a system is performing as it should.
When Should Solar Temperature Sensors Be Replaced?
Over time, a temperature sensor can wear or fail, affecting how accurately the system reports and controls heat. It is worth considering a replacement when you notice signs such as:
- Inaccurate readings – the reported temperature does not match the system's actual state
- No response – the sensor fails to register or react to temperature changes
- Erratic operation – the system runs too hot or too cold, or behaves unpredictably
- Visible damage – the sensor shows cracks, corrosion, or general wear
Replacing a faulty sensor restores accurate measurement and control, helping the solar installation run safely and efficiently.
Are Solar PV Spares Brand-Specific?
Yes, in most cases. Renewable spares are frequently designed to suit particular systems, so a Grant sensor is intended for the relevant Grant installations. Before ordering, check the make, model, and part number of the system you are working on to confirm the spare is a match.
