Daily use and maintenance

  • Daily maintenance of solar water heaters

    1. When installing a solar water heater, there may be dust or oil odor in the water supply pipe. When using it for the first time, the faucet can be turned on to remove debris first.
    2. The water stored in the solar water heater should be regularly discharged according to the local water quality conditions, and the drainage time can be selected when the collector is relatively low in the morning.
    3. The surface of the solar water heater is regularly wiped according to the amount of dust falling in the area. It can be self cleaned when it rains, and maintaining a clean surface of the water heater can achieve high heat collection efficiency.
    4. When not using hot water on consecutive sunny days, the temperature of the hot water is very high. When using a solar water heater, please turn on cold water first and then hot water to avoid burns.
    5. The outlet end of the faucet generally has a filter device, and the scale and debris in the water pipe will accumulate in this network. It should be regularly removed and cleaned by oneself to increase the water flow and ensure smooth flow.
    6. In winter, it is common for pipelines to freeze. If it is found that the pipeline has frozen but has not yet cracked, and the temperature rises, it can generally be automatically unblocked. You can also use an electric hair dryer to blow, or wrap a towel around the water pipe, and then slowly pour warm water over it. Do not use fire to bake, tap the pipe, or use boiling water to quickly scald it, as it may cause the pipe to burst. Multiple freezes and blockages can easily cause pipeline cracking, so it is necessary to strengthen pipeline insulation measures.
    7. Solar water heaters require cleaning, inspection, and disinfection every two to three years on average. Users can also do some disinfection work themselves, such as buying some chlorine containing disinfectant and pouring it into the water inlet, allowing it to soak for a period of time, and then releasing it, which can achieve a certain disinfection and sterilization effect.
    8. Solar water heaters require cleaning of the interior of the vacuum tubes for an average of two to three years to prevent scaling inside the vacuum tubes from affecting the heat absorption effect.
    9. If a solar water heater is equipped with a dedicated instrument, attention should be paid to lightning and electricity protection. When lightning strikes, do not take a shower and unplug the electric heating plug.

  • Daily use of solar panels

    As more and more household users install solar photovoltaic power generation systems, more and more people want to know about the maintenance and upkeep of solar panels. The editor has compiled some practical maintenance methods for photovoltaic solar cell modules:

    1. To maintain the cleanliness of the solar panel's lighting surface, if there is dust, a clean wire duster can be used to clean it. If there is dirt that cannot be removed, rinse with clean water and then wipe the water stains dry with a clean cloth. Do not clean with corrosive solvents or wipe with hard objects. When encountering snow, it is necessary to clean it up in a timely manner.
    2. Regularly inspect the metal brackets of solar panels for corrosion, and regularly apply paint anti-corrosion treatment to the brackets. The square array bracket should be well grounded.
    3. During use, it is necessary to regularly (such as 1-2 months) inspect the photoelectric parameters and output power of the solar panel to ensure its normal operation.
    4. During use, it is necessary to regularly (such as 1-2 months) inspect the packaging and wiring connectors of solar cell components. If there is water ingress, discoloration of the battery cells, loose, disconnected, or corroded connectors, timely repair or replacement should be carried out.
    5. For solar panel brackets with polar axis automatic tracking systems, it is necessary to regularly check whether the mechanical and electrical performance of the tracking system is normal.

    This is the method for maintaining solar panels. Doing a good job in the maintenance of solar panels can ensure timely detection and resolution of faults, increase service life and power generation efficiency. When choosing solar panels, it is important to choose an experienced manufacturer with guaranteed quality. Jingtian Power produces a wide range of solar panel specifications and models, suitable for various application fields and complex terrain types. Quality is checked layer by layer, ensuring that every product receives customer recognition and satisfaction. You are welcome to leave a message for consultation or call to negotiate cooperation.

  • What is a photovoltaic energy storage battery?

    Photovoltaic energy storage is an indispensable equipment in independent photovoltaic power generation systems, which can play two major roles: energy regulation and load balancing. At present, photovoltaic energy storage mainly utilizes batteries to convert the electrical energy output from photovoltaic power generation systems into chemical energy for storage in case of insufficient power supply. The commonly used energy storage battery is lead-acid battery.

    Lead acid batteries are widely used due to their universal materials, low prices, stable performance, and safety and reliability. The commonly used models of lead-acid batteries include 2V, 4V, 6V, 8V, 12V, 24V and other series. The commonly used lead-acid batteries are mainly divided into three categories:
    1. Ordinary battery; The electrode plate of a regular battery is composed of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are stable voltage and cheap price; The disadvantages are low specific energy (i.e. the energy stored per kilogram of battery), short service life, and frequent daily maintenance.
    2. Dry charged battery: Its full name is a dry charged lead-acid battery. Its main feature is that the negative electrode plate has a high storage capacity, and can store the electricity obtained within two years in a completely dry state. When in use, only electrolyte needs to be added, and it can be used after 20-30 minutes.
    3. Maintenance-free batteries: Maintenance-free batteries, due to their structural advantages, consume very little electrolyte and do not require the addition of distilled water during their service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self discharge. The service life is generally twice that of a regular battery. There are also two types of maintenance-free batteries on the market: the first type is to add electrolyte at the time of purchase without the need for maintenance during use (adding supplemental solution); Another type is that the battery itself is already filled with electrolyte and sealed when it leaves the factory, and users cannot add any additional liquid at all

    Maintenance-free batteries are currently commonly used energy storage devices in photovoltaic systems, but energy storage devices are still a relatively weak link in the technology of the entire photovoltaic power generation system. Therefore, if not selected properly, it will increase the operating costs of the entire system. So now countries around the world are fully researching how to increase energy storage without increasing costs.

  • Daily maintenance methods for solar courtyard lights

    Solar courtyard lights are one of the most common types of lighting fixtures in villa courtyard decoration. They not only serve as lighting, but also serve to enhance the atmosphere of the environment, increasing the outdoor leisure and atmosphere of the family. So, how to maintain solar garden lights?

    1. Do not hang items on the lamp, such as airing blankets.
    Frequent switching can greatly reduce its service life, so try to minimize the number of switches when using lamps.
    If the lampshade is found to be tilted during use or cleaning, it should be easily corrected to maintain aesthetics.
    4. When adjusting the lampshade, be careful to avoid reflective shadows from the tripod inside the lamp during lighting.
    5. According to the light source parameters provided on the label, replace the aging light source in a timely manner. If the light source is red, black, or black, and the light source does not bounce, it should be replaced in a timely manner to prevent unsafe phenomena, such as burning the ballast.
