610KW Solar PV Array Completed at Trafalgar Drystack, Portchester

Installation of a 610KW solar PV array by Solar Voltaics is completed at Trafalgar Wharf Drystack. The Drystack is home to over 300 motor boats and Rigid Inflatable Boats (RIBs) between 4m and 13m long. Trafalgar Drystack is the largest boat storage facility in Hampshire and the UK. The installation will reduce the electrical demand

Commercial Solar Engineers

Solar PV systems are very reliable, but like most technologies, they still need to be maintained to ensure maximum output efficiency. With our annual solar maintenance plan, you can enjoy peace of mind knowing that your system is in the best possible condition.

Sign up for an annual maintenance plan including a free inspection visit every year and ensure your system is safe, clean and producing its maximum potential generation. Callouts and the first half hour on site are free throughout the year if your system develops a fault (travel costs for sites outside a 30 mile radius of our office and for IOW may apply).

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

Keeping Your Solar Panels Running Smoothly

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 on a regular basis. This way, we can spot any potential problems early, keeping your energy generation stress-free.

Protect Warranty

Many solar panel manufacturers require regular maintenance as a condition of their warranty. Failure to comply with these conditions may void the warranty, leaving you uncovered for any repairs or replacements if needed in the future.

Maximise Efficiency

Regular cleaning and maintenance ensure that solar panels operate at their maximum efficiency. Dust, debris, and other obstructions can significantly reduce the amount of sunlight absorbed by the panels, leading to lower energy production.

Reduce Safety Hazards

Our maintenance plans are crucial for preventing electrical fires and safety hazards that can stem from faulty wiring, malfunctioning inverters, or panel damage in solar panel systems. These problems may not be evident right away but can be significant dangers.

Did You Know?

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

Frequently Asked Questions

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.

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 discolouration, 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.

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 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.

The Business Case

Ensure a Positive ROI

A solar maintenance plan is essential for businesses to ensure their solar systems operate at peak efficiency, avoiding costly disruptions.

Regular inspections and upkeep prevent electrical fires, panel damage, and other safety hazards, extending the system’s lifespan. This proactive approach not only safeguards against potential dangers but also maximises energy savings and investment returns.
