Why Have an Annual Solar Panel Maintenance Plan?

At Solar Voltaics, we know keeping your solar PV system in the best possible condition is key to its performance and your savings, which is why we offer comprehensive solar panel maintenance packages to safeguard your investment. Whilst our solar energy systems are designed to last for at least 30 years (benefitting from premium materials from reputable manufacturers), your panels should have an annual ‘check up’ to ensure they’re still running as good as new.

Our comprehensive maintenance solutions for homes include monitoring your system remotely and conducting regular site visits to avert any loss in performance and protect your investment in solar power. Even for domestic systems installed by other companies, our approach is to quickly identify and fix any faults, ensuring your system remains a way of reducing your energy bills.

4.2kW system in Chichester

This landlord wanted to have solar on the roof of their rented property to reduce the tenants energy bills. We fitted a PV system and a Solis inverter that would provide an annual generation of around 4700kWh. We also fitted an EV charger to futureproof the house, ready for tenants with electric vehicles.   System

Annual Solar Maintenance Packages from £239

While Solar PV technology is known for its reliability, maintaining scheduled upkeep is key for sustaining optimal output. In the UK, millions of solar systems have been installed on homes for several years, some exceeding the 5-year mark, and while the majority may operate smoothly, irregular checks mean many homeowners might be unaware of their system’s true performance.

If your solar panels are not living up to their potential or have stopped working, you stand to lose free solar energy for your property and the accompanying government Smart Export Guarantee initiative, without any option to recoup lost energy production.

Please note that we currently offer solar maintenance and servicing packages to domestic customers across the South East. To find out more information on our service area, please get in touch with the Solar Voltaics team.

Common Solar Panel Pain Points

Generally, solar panels are pretty low-maintenance because they don’t have many moving parts, but it’s still a good idea to have them serviced. This way, we can spot any potential problems early, keeping your energy generation stress-free.

Drop in Performance

Regular maintenance is crucial for solar panels to avoid a drop in efficiency. The main reasons include the buildup of dirt and debris, shading caused by new constructions or trees growing nearby, or the inevitable wear and tear that comes with continuous use and exposure to outdoor conditions.

Exposure to Safety Issues

Electrical fires and other safety hazards in solar panel systems can arise from problems like faulty wiring, malfunctioning inverters, or damage to the panels. These issues might not show up at first, but can turn into significant dangers if ignored – our solar maintenance plans will ensure your safety.

Increased Repair Costs

Small problems in solar panel systems, such as minor cracks or loose connections, can become big, expensive issues if they’re not fixed quickly. These seemingly minor issues can escalate, leading to substantial damage and high repair costs. Regular maintenance identifies and fixes these problems early.

Did You Know?

Solar panels can lose up to 25% of their efficiency if not regularly maintained.

Frequently Asked Questions

How often should solar panels be cleaned?

Solar panels in the UK should typically be cleaned once or twice a year. The frequency can increase in areas with higher levels of dust, pollen, or bird droppings. Regular cleaning ensures that panels operate at optimal efficiency by removing obstructions that block sunlight.

While rain can naturally clean panels to some extent, it often isn’t enough to remove all debris. Professional cleaning or using a soft brush and soapy water can effectively maintain cleanliness without damaging the panels.

How does weather affect solar panel maintenance?

In the UK, weather conditions can significantly affect solar panel maintenance. The frequent rain can lead to mineral deposits or lichen growth, while winds can bring dust, leaves, and other debris. Winter snowfall can cover panels, drastically reducing their output.

Additionally, temperature fluctuations can cause expansion and contraction in solar panel materials, potentially leading to microcracks. Regular maintenance must account for these weather-related challenges, ensuring that panels are cleaned and inspected to deal with the specific conditions prevalent in the UK.

How do solar PV cells work?

Photovoltaic (PV) cells convert radiation from the sun into electricity.  A typical PV cell consists of a wafer of semi-conducting material, usually silicon, manufactured with two electrically different layers.

When sunlight hits the cell it excites the electrons within the silicon, creating an electric field across the layers and causing a flow of electricity.

Is remote monitoring something you offer?

Remove the worry of monitoring your system. If your system fails without you knowing, you could lose many hundreds of pounds in lost Feed-In Tariff revenue and energy production. Our remote monitoring allows us to measure your generation output every day and contact you promptly if we detect a fault or loss of power.

We will install a replacement generation meter with roaming sim card which transmits your generation data to a central portal where we can monitor performance. We will also complete the paperwork for the meter swap and send it to your Feed-In Tariff licensee. The annual fee covers the cost of the sim contract and the monitoring.

Can bird nesting affect solar panel performance?

Bird nesting under solar panels can lead to several issues. Nests can obstruct air flow and cause panels to overheat, reducing their efficiency. Bird droppings can also block sunlight and corrode the panel’s surface. To mitigate this, you can install bird-proofing measures like spikes or mesh around the panels.

Regular inspections are crucial, especially during nesting season, to ensure that any nests are promptly removed and preventive measures are in place to deter birds from nesting under the panels.

Why is shade a problem for solar PV systems?

Any shade, such as from trees or neighbouring buildings, can have a large impact on the performance of a PV system. Because modules are constructed from a number of PV cells interconnected together, if one cell is shaded it has a knock-on effect that prohibits the whole module from generating electricity.

To work effectively, we recommend that whole PV array needs to be free from shade for the majority of the day.

What are the signs that solar panels need maintenance?

Signs that solar panels require maintenance include a noticeable drop in energy output, visible physical damage like cracks or discoloration, and alerts or error messages from the solar monitoring system. Regular monitoring of energy output can help identify any unusual patterns or drops in efficiency, indicating potential issues.

It’s also important to visually inspect your panels for any signs of damage, especially after extreme weather events. Addressing these issues promptly can prevent further damage and maintain the efficiency of your solar system.

Quick Facts About Solar Maintenance

  • Solar inverters, critical for converting solar energy to usable electricity, typically need replacement every 10-15 years
  • Modern solar systems often include monitoring tools that alert owners to efficiency drops, indicating the need for maintenance or cleaning
  • With proper maintenance, solar panels can last up to 30 years, maintaining about 80% of their original efficiency by the end of their lifespan
  • Most solar panels come with up to 25 year warranty. Regular maintenance ensures warranty conditions are met, protecting your investment
  • A single relatively small commercial roof installation of 30 KW will save over 26 tonnes of CO2 emissions compared to fossil fuels
