Commercial Solar Maintenance - PV & Hot Water

Rayotec Commercial Solar PV

Why Regular Maintenance is Important

Solar panels are a valuable investment into your future and you need to know that you are benefiting from the best return on that investment. As with any other asset, such as company vehicles, regular servicing ensures that your solar energy system is running efficiently and safely and that it will continue to do so for many years to come.

When considering the ongoing health of your solar panels, keep in mind that regular maintenance checks also:

  • Ensure your system is fully compliant with health & safety regulations
  • Maintains the validity of your Manufacturers Guarantee which require regular service checks by accredited specialists
  • Can resolve undetected faults which can influence the efficacy, and therefore savings provided, by your solar array

In addition, for those of you who enjoy the benefits of Solar Thermal Hot Water, regular maintenance checks are essential as:
  • Long periods of stagnation of the system will soon damage components, pipe joints and the solar panels
  • The pressurised, high temperature system can be at risk from undetected faults if they are not identified and resolved
  • The glycol-based antifreeze in the solar transfer fluid has a limited life expectancy. When it ceases to do its job, the freezing of the fluid can cause serious damage to the panels and other major components

Our Services

Rayotec Ltd offer bespoke service packages which are tailored according to the scale and requirements of  your system to ensure that you receive a cost-effective  service that works for you. We generally recommend that  commercial projects receive, at the very least, a basic annual health check. We also have a panel  cleaning service for commercial properties and have a comprehensive service and repair packages. We  cover most areas throughout England and Wales.
