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

Frequently Asked Questions

What our customers most commonly ask us about our Commercial Solar service

  • What information do I need to send Rayotec to get an estimate for an annual solar maintenance?
  • Ideally a schematic and any technical documents you have. It will often be in the building O&M manual. With PV systems the schematic should be located near the inverter. If you have no information please send us the full address and we will assess the site using Google Earth. If you are unsure on what you need to do then you are welcome to contact us and we will be happy to help guide you.
  • How often do commercial solar PV systems need to be inspected?
  • Public buildings, commercial buildings and communal residential systems need to be tested annually. Rented accommodation (single dwelling) will need testing every 5 years.
  • How often do commercial solar thermal / hot water systems need to be inspected?
  • All commercial systems need to inspected annually. This includes public buildings, schools, apartment blocks, offices, factories & warehouses. Single dwellings need to be inspected every 4 years.
  • Are all solar commercial inspections and reports of the same quality
  • We have seen many reports from other companies of a very poor standard. Essential tasks like testing each string, which is included within the MCS solar standards, are omitted to save time and reduce cost. Without these tests there is no way to know whether the system is safe or not.
  • How long should a solar panel last for?
  • Solar PV panels generally have a lifespan of at least 25 years. Their performance will decline slowly with time. Solar heating panels should last for over 20 years if they are regularly maintained and there is good hot water usage in the building.
  • Can my solar PV system still be maintained if there is no access to the roof?
  • The most important tests are done around the inverter where all the strings can be tested. This is normally found in a plantroom, riser or electrical cupboard. The AC and DC isolators are also fitted next to the inverter. If we do have safe access to the roof, our solar engineer will look at the condition of the panels, framework and DC cabling.

Steve Brown

I would just like to say how happy we have been with the service from Rayotec. I was always kept up to date any works taking place, if there was any issues I was informed straight away and then kept in the loop On how things were being sorted. When I called with any questions the phone was answered prompt and if not the right person then a message was passed over and then I received a call back that day. All the staff were polite and friendly. Thank you for being a great company to work with and we look forward for our yearly service to take place very soon.

Rayotec have been working with HR Wallingford ltd at Howbery Park for several years, helping us to continue our aim on reducing our carbon footprint by using Rayotec solar thermal system to heat our hot water requirements. This coupled with Rayotecs after sales service, providing peace of mind for our ongoing maintenance requirements.

Natalie Allen

Mina and the team at Rayotec are a pleasure to deal with. Any communications are always handled politely and promptly and they are always on hand to offer unbiased advice on various systems with an emphasis on customer care. I would recommend Rayotec for any solar needs, be it installation or maintenance.

Good afternoon, we have just completed a new Solar Panel installation for the Environment Agency at Red Kite House in Oxfordshire. The company we used was called Rayotec and can I just say what a pleasure it was working with such a professional company, from start to finish the works were exceptional. We had a install engineer called Paul Elliot who was polite and hard working and his knowledge of Solar heating was second to none. All of the H&S documentation was supplied before works commenced and O&M manuals were issued after completion and handover. Mina Sabba the contracts manager has a very hands approach and kept me supplied with all the answers to any queries I had. Sol Services will be using the company again for any Solar Heating works.

Rayotec have reviewed our solar panel system and disconnected a broken panel. They have been very easy to deal with and provided clear costings and information in advance of their visit. The engineer was very competent, efficient and on time. Everyone I have spoken to at Rayotec has been friendly and helpful, they even found a replacement panel for me on Ebay!

Liam Williams

Use this company for our Commercial solar maintenance sub contractor. So easy to deal with, prompt and have never let me down. Would highly recommend.
