Regular Inspections: The Key to Maintaining Efficiency

Regular inspections of your solar power system are essential in extending their lifespan and ensuring that they function optimally. Conducting frequent check-ups can help you identify any signs of damage, underperformance, or potentially hazardous situations early on, allowing you to act swiftly to address the issue.

We recommend conducting visual examinations every six months to a year. Be sure to keep an eye out for:

1. Signs of damage, like cracks or breakages.

2. Discolouration or warping of the panels.

3. Loose or torn connections in wiring.

4. Evidence of animal activity, such as nesting or burrowing.

If you notice any issues during your inspection, contact a solar panel specialist, like Leoht, to provide professional guidance and repairs as needed.

Cleaning Your Solar Panels for Optimal Performance

Keeping your solar panels clean is essential for maintaining their efficiency. Accumulated dirt, dust, bird droppings, and other debris can limit the amount of sunlight that reaches your panels, consequently reducing their power output. Here are some tips to help you clean your solar panels effectively:

1. Gather the right cleaning tools: Invest in a high-quality soft brush with an extendable handle, a squeegee, and a mild cleaning solution designed specifically for solar panels. Avoid using abrasive cleaners or hard bristles, which could cause scratching or damage to your panels.

2. Choose the right time: Ideally, clean your solar panels early in the morning or late in the evening when the temperature is cooler. This prevents water from evaporating too quickly, leaving streaks or residue on the panels.

3. Safety first: Ensure proper safety measures are in place before cleaning. Wear slip-resistant footwear, use a secure ladder if needed, and ask someone to assist or supervise you during the cleaning process.

4. Gently clean your panels: Lightly wet the panels with your cleaning solution and then gently scrub them with the soft brush. Follow this by using the squeegee to remove any remaining water from the surface, preventing streaks or dirt build-up.

If your solar panels are difficult to access or you're unsure about cleaning them, consider hiring a professional cleaning service to ensure the job is done safely and correctly.

Maintain the Surroundings to Reduce Panel Blockage

To maximise the efficiency of your solar panels, it's crucial to ensure they receive ample sunlight throughout the day. Overhanging branches and obstructing vegetation can cast shadows on your panels, significantly affecting their performance.

Regularly prune any trees or plants that may cause shade, paying particular attention during the spring and summer months when plants grow more vigorously. By maintaining the surroundings of your solar array, you can prevent unwanted shading and maximise your energy generation.

Monitoring Your Solar Panel Performance

Monitoring your solar panel output is an excellent way to identify any potential issues affecting their performance. Some solar power systems come equipped with monitoring software, while others require you to install an independent monitoring system. Regardless of your set-up, regular monitoring enables you to detect any drop in energy production, prompting you to inspect the cause, be it dirt accumulation or technical malfunctions.


The long-term success of your solar power system is highly dependent on regular maintenance, timely cleaning, and ongoing monitoring. By taking care of your solar panels and ensuring their surroundings remain conducive to sunlight exposure, you can effectively boost their efficiency, reduce your carbon footprint, and continue saving on utility bills.

Arming yourself with the right knowledge and adhering to a well-structured maintenance routine will not only guarantee an extended lifespan for your solar panels but also contribute towards sustainable, clean energy generation for years to come.

Remember, prevention is better than cure. By addressing potential issues before they escalate, you can preserve the stellar performance of your solar panels and maximise the return on your investment in green energy.
