Servicing & Maintenance

New energy Solutions Ltd provide domestic maintenance for Solar PV,

Thermal Thermodynamic and hot water systems all over the UK

Solar PV

We are constantly receiving calls from property own-ers, interested in solar panel servicing, after the solar panels on the roof of their home have a reduction in performance due to damage or ware and tear. This can sometimes mean expensive repairs/replacements, however a lot of the time it’s a simple clean or small repair.

Has your system been checked?

Its ideal to have your system diagnostically checked every 2/3 years to check that all the panels and inverter are working correctly.

Besides keeping your system healthy and your invest-ment safe, there are actually cost saving benefits to servicing your PV. Inverter servicing and module cleaning will prevent the amount of solar power generated by your system from slipping below what it should be.

This is a relatively inexpensive maintenance check compared with what you may lose over many years

Thermodynamics

Thermodynamics is the most recent solar technology to be brought to the UK market. In the early days there was not that many experience installers, so unsurprisingly the system broke down, then with the added problem of getting them fixed.

Fitted correctly the Thermodynamics runs 365 days a year and is capable of operation day and night and will operate in temperatures as low as -18̊ C.

As a result of the simple, sustainable product design, thermodynamic water heating systems need little maintenance. Since the refrigerant fluid circulates in a closed cycle, and does not degrade over time, so there is no need for refuelling. However if you suddenly lose hot water then there is obviously a leak or the compressor has failed.

Most people will call out the plumber who cant fix the issue. Usually needs a fully qualified F-Gas engineer who is experienced with the systems.Infrequent check-ups—once or twice every 3/5 years—may be beneficial to keep the system up and running in the long run.

The water tank that is connected to the system should be maintained as any other water tank: depending on the hardness of the water, it needs to be flushed every few months down to once a year. This should be done to pre-vent limescale build-up.

The thermodynamic panels themselves may be cleaned once in awhile.

Thermodynamic water heating is an excellent way of re-ducing your bills and your carbon footprint.

Solar Thermal

Due to the high operating temperatures of solar panels, the heat transfer fluid requires replacing every two years. During every service visit we measure the consistency of the fluid and will replace it if necessary without additional cost. This ensures maximum protection for your system pipe work, pump and solar panel manifold.

We provide a full service and repair which includes a replacement of the heat transfer fluid. We carry spare solar pumps, solar expansion vessels , controllers , pressure relief valves and sensors. We can also source any broken or faulty tubes.

Typical faults

  • Faulty pumps
  • Controller issues
  • Faulty sensors
  • Leaking joints: Air locks or (very rare)
  • Expansion vessel perforated

Our initial start will be to inspect the Pump and operation.

Then sensors, pressure relief valve, expansion vessel and the
pressure settings. Pressure test the system and a visual inspection
on the panels.

We can service and maintain all types of systems.

Flat plate and evacuated tube systems.

Solar panels work by allowing light into the solar cells. The more light that hits a panel, the more power it will generate. Due to the upwards angle of solar panels, they are more prone to bird droppings and a build-up of general dust and dirt that does not wash off with just rain. This reduces the amount of light hitting the panel and reduces its output. As the projected energy figures claimed by solar panel manufacturers and installers are based on the optimum performance of clean solar panels, this build-up of dirt can adversely affect the panel’s ability to meet those projections. So it is important to clean solar panels in order to protect and maintain your investment.

Regular solar panel cleaning will also help you to make the most of the government feed-in tariff.

While solar panel cleaning in the UK is relatively new, in other parts of the world solar panel cleaning has been around for a long time. Early adopters of the technology soon realised that if their solar panels were not cleaned regularly, they would not run at their optimum perfor-mance. There has been study in the U.S. suggesting solar panel cleaning is not necessary in some of their climate, but it is proved that solar panel cleaning is necessary in the UK.

If you consider that your windows are vertical and the rain should wash most of the dirt and dust off, but we still have to clean them. Your Solar panels are on an angle so they are likely not to wash all the residue off, creating a slow build up and lowering the efficiency.

Rainfall will take care of most of it but not all – we advise having them cleaned every 2-3 years, this cost will obviously impact on you PV income but usually not as much as having inefficient system.

How much money would it cost me to neglect solar panel cleaning?

It is reasonable to assume that solar panels can loose 15-30% of their efficiency if not cleaned properly. This literally means that they will generate 15-30% less electricity, which you now will have to source from the utility company at their price rates. This easily adds a couple of years extra on the payback time.
