If rooftop solar panels are installed, there is a demand for harnessing maximum solar output from them. Cleaning keeps the solar panels at maximum efficiency. So how often must solar panels be cleaned? This guide will answer that question while also telling you why it is important to clean your solar panels regularly.
Why Clean Your Solar Panels Regularly?
Nature exposes solar panels to contamination. Dust, leaves, bird droppings, and cuttings of trees can be the most common contaminants. When a cover stands between sunlight and solar panels, energy generation falls. Cleaning ensures they work while energy bills go down.
How Often Should I Clean Them?
This depends on many variables. Some of these are:
- Location: Living in a dusty or polluted area may warrant frequent cleaning.
- Weather conditions: Areas with heavy rainfall might not need manual cleaning, as natural showers may wash off dirt.
- The North versus the South side: If in the vicinity, trees or birds can get attention from debris and droppings.
- Performance monitoring: Monitor your output regularly. If you see a sudden drop in power, it may be time to clean your panels.
General Recommendations for Cleaning Frequency
- Every 6-12 months: Biannual or annual cleanings are generally a good fit for most residential systems.
- More frequently in certain conditions: If there's dirt buildup or loss of efficiency perceived, cleaning should be done every 3 to 6 months.
- After storms or heavy winds: These occasions precipitate more debris onto your panels, so it is time to have an inspection and cleaning.
Do It Yourself or Hire Solar Cleaning Companies?
Cleaning solar panels is an easy task, but safety precautions must be observed in the process. If you feel comfortable while standing on your roof and you have all the necessary tools that are required, basic cleaning can be done by you:
- Soft brush or sponge.
- Rinse with clean water; no chemicals should be used.
- Make sure you consider your safety when working at heights.
However, in the case of thorough cleaning or if the roof proves inconvenient or impossible to reach, hiring professionals would be the best choice. This is where solar cleaning companies are called in, as they hold the technical capability, equipment, and safety gear to carry out the job properly.
Professional Solar Panel Cleaning Advantages
- Good energy output: Clean panels allow maximum solar energy conversion; professionals maximize cleaning.
- Longer life: Less dirt leads to less abrasion and tears over time.
- Saves time: You can save time if you hire them.
- Safety: Professionals deal with high heights and awkward angles safely.
Choosing a Solar Panel Cleaning Company
When selecting a solar panel cleaning company, keep the following in mind:
- Look at the reviews for the company. Also, ask for references to assure yourself of the quality of service.
- Confirm that they use only environmentally friendly cleaning solutions and materials.
- Ask them about their safety practices and the certifications they hold.
- Compare prices and packages and decide what works best for you.
Cleaning of the rooftop solar systems is indeed necessary to maintain efficiency and longevity. Depending on whether you want to do it yourself or want to engage solar cleaning companies, regular maintenance must be kept to ensure the best operation of solar systems for years to come.
