Solar panels are very durable and the best modules can last 25+ years. Diesel generators and other types of equipment with moving parts are constantly subject to friction and require frequent parts replacement. Not so with solar panels:
- Solar panels convert sunlight into electricity while remaining stationary so their maintenance needs are simpler.
- Portable Power Stations Batteries charged with solar energy also has this advantage over traditional power stations with fuel engines.
In this article, we discuss the maintenance requirements for solar panels and portable power stations.
What Type of Maintenance Do Solar Panels Require?
Solar power generation systems can generate electricity for decades, as long as the following requirements are met:
- Clean the surface of the solar panel regularly. Dust and other particles block sunlight, reducing power generation over time.
- Replacement of system components reaching the end of life before solar panels.
- Replace any solar panels that fail prematurely (in which case the warranty covers you).
How Often Should I Clean Solar Panels?
As a rule of thumb, solar panels should be cleaned at least every six months, but they will perform better if they are cleaned more frequently. If objects such as dust and leaves are allowed to accumulate on the surface of a solar panel, they block some of the sunlight that would normally be converted into electricity. There is no doubt that regular cleaning of your solar generator will help it work better.
Remember, solar panels are only one part of a complete solar system. They are used in conjunction with other equipment that has a short lifespan and must eventually be replaced:
- An inverter is a device that converts the direct current generated by a solar panel into the alternating current required by home appliances. The typical lifespan of a solar inverter is 10-12 years, once it reaches that point it needs to be replaced.
- If you use batteries to store the electrical output of your solar panels, you will also need to plan for replacement. Lead-acid batteries typically last 2-3 years, while lithium-ion batteries last around 5-10 years (depending on manufacturer and brand).
There's also the small possibility that one or more of your solar panels could fail before the end of their useful life, but if you have a solid warranty, that's not a problem. If this happens under warranty, the faulty panel will usually be replaced by the supplier.
Solar panel systems are often equipped with monitoring tools to track their daily power generation, measured in kilowatt-hours (kWh). If you notice a sudden drop in power output, it could indicate a problem with one or more panels.
- Remember that in winter and on cloudy days, it is normal to be less productive because there is less sunlight available.
- However, if your solar system is less efficient than normal on a sunny summer day, you may have a technical issue that needs attention.
You can clean the solar panels yourself, but for larger rooftop installations, a professional cleaning service is recommended. They operate at much higher voltages than portable systems and also involve working at heights.
What's the Best Way to Clean Solar Panels?
When cleaning solar panels, you must avoid using any tools and methods that may cause damage. If a solar panel is damaged by improper cleaning procedures, you could also void its warranty.
Solar panel maintenance is relatively simple when you use the right tools. Here are some suitable cleaning methods that you can use without worrying about damage:
- Clean the solar panels with a hose
- Clean them with a soft brush
- Wipe the surface with a squeegee
- Use a leaf blower
Never clean solar panels with tools that will scratch their surface, such as roof rakes and snow brushes. You should also avoid hot water, especially in winter, as sudden temperature changes can damage your solar panels. Chemical cleaners can also damage solar modules and should be avoided.
While cleaning the solar panels, you can also perform a visual inspection. Look for cracks or any other signs of damage, you can also make sure there are no loose connections or mechanical parts. If you have a fixed solar installation, you should also check the racking system that holds the PV modules in place and make sure there are no loose parts.
Solar Panel Maintenance: Other Advice
When a solar panel is placed in the shadow of other objects, its efficiency is greatly reduced, which is the same effect as dust accumulation. Because the sun's position in the sky is constantly changing, shadows move during the day and throughout the seasons. Vegetation and new construction can also create shadows that weren't there when your solar panels were first installed.
Shading is not a problem with portable solar panels as they can simply be removed. They can be a problem for rooftop solar systems that are fixed in place.
- Branches that cast shadows on solar panels should be pruned.
- When installing other types of rooftop equipment such as network pans and air conditioning units, make sure they do not cast shadows on your solar panels.
The solar panels are designed for all weather conditions, including high ambient temperatures. Solar panels can reach temperatures up to 65℃ (149℉) without damage. However, to be on the safe side, you should avoid cleaning solar panels when they are hot. You should also avoid washing solar panels when they are hot, as sudden drops in temperature from cold water can damage them.
If you own a portable solar panel, you should follow the same instructions provided for the fixed modules: avoid using any cleaning tools and chemicals that could damage its surface. However, portable solar panels are different from rooftop photovoltaics, please follow the manufacturer's manual strictly. Portable solar panels have an added advantage: They can be stored away when not in use, so you can reduce your exposure to dust and dirt. This is not possible with roof-mounted solar panels as they are fixed.
Solar panels are often used as part of a portable power station. Unlike diesel generators, which rely on fuel supplies, solar generators use energy input that is free and available everywhere. In this case, you need to keep some additional maintenance requirements in mind.
- Do not use the power bank near flammable and explosive items. Even a small electrical spark can start a fire or cause an explosion.
- The portable power station should be stored in a clean and dry place. Otherwise, dust and moisture may seep into the device and damage internal components. The portable power station should also be dustproof and waterproof during use.
- Avoid frequent charging and discharging of the power station, as this will shorten the life of the battery. If the power station is allowed to fully charge before each use, it can last longer.
- Do not overload the portable power station. Check the rated power output specified by the manufacturer and make sure not to exceed this wattage when connecting multiple devices to the power station.
- You should read the manufacturer's instructions and follow them carefully. This way, you can avoid electrical failures and extend your product warranty.
Portable power stations should be covered when not in use, but need proper ventilation when charging or discharging. Additionally, portable power stations should not be covered with blankets or stored in enclosed spaces while they are in operation, as their batteries can overheat due to a lack of ventilation. Unlike solar panels, which are designed to run in direct sunlight, batteries inside portable power stations can heat up easily.
If your power bank has not been used for more than 3 months, it is recommended to discharge the battery to 0% and then charge it to 100% to avoid calibration errors caused by long-term non-use.
For long-term storage, please keep the battery power between 30%-60%, and store it in a room with low humidity and no corrosive gas. If the battery is in a low power consumption state for a long time, it may damage the battery and reduce the life of the whole machine.
Technical specifications for portable power stations include battery capacity and how long they can run with different types of electrical equipment. If your portable power station is discharging faster than expected, the battery may be failing.
