Advantages:
1. The wall-mounted solar energy on balcony is equipped with a pressurized water tank. This water tank can be connected to tap water, and there. There will be no problems such as traditional solar water supply. Water pressure is also guaranteed.
2. The balcony wall-mounted solar energy adopts the thermal cycle method, so even if the weather is as cold as minus 30° in winter, there will be no freezing phenomenon. , and the security performance of the system is relatively high.
3. The installation location is convenient. Even if it is installed on the first floor or ground floor, it can supply water to high-rise buildings without any external power devices.
4. Use both photography and electricity. If there is no sun, you can also use electric energy for heating, so you can enjoy hot waterin winter without sun
< p>Disadvantages:
1. The price is high and the installation cost is high. The current price of an ordinary 100 liter. ranges from about 4,000 to 5,000 yuan.
2. The water tank is relatively small. If used by one person, it can only be heated by solar energy. be heated by electricity. The water tank is 120 liters.
3. Regional restrictions are relatively strong. Generally, they are more practical in the south but basically useless in the north.
4. If the weather is too cold, antifreeze must be replenished or replaced regularly, increasing after-sales costs.
5. The installation is complicated, but it is usually installed by workers.
6. The functional efficiency of solar hot water is not very high.
When installing an awning on a balcony, howent install it to extend its life?
Solar panelscan be used through glass, but this will affect some conversion efficiency.
Solar energy is a renewable energy source. It refers to the radiant thermal energy of the sun (see the three modes of propagation of thermal energy: radiation), and its main manifestation is often called solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters.
Advantages of solar energy
(1) Universal: The sun shines on the earth, without geographical restrictions, regardless of land or oceans, whatever the mountains or on the islands. It is available everywhere, can be directly developed and used, is easy to collect, and does not require mining or transportation.
(2) Inoffensif: The development and use of solar energy will not pollute the environment. It is one of the cleanest sources of energy, which is extremely valuable today as environmental pollution becomes more and more serious.
(3) Huge: The energy of solar radiation that reaches the Earth's surface each year is approximately equivalent to 130,000 billion tons of coal, and its total amount constitutes the greatest energy that can be developed in the world today.
(4) Long-lived: generated by the sunAccording to nuclear energy rate estimates, hydrogen storage is sufficient to last tens of billions of years, and the lifespan of Earth is also about billions of years old. In this sense, we can say that the energy of the sun is. inexhaustible.
When installing an awning on the balcony, how to install it to extend its service life?
1. If youIf you want to install a parasol on an open balcony, you must first support the frame. Before supporting, check the frame to make sure it is smooth and free of burrs. Once the frame supports are in place, place the solar panels on the frame with expansion joints between each panel. Press the EPDM rubber strips to the street and secure them with self-tapping screws. The skeleton is placed approximately 1 meter in the middle of the width of the board and secured with self-drilling screws. Finally, use corner codes to fix it on the wall, then place the solar panel inside. At the same time, the edge sealing work should be done well. The boards above the awning are covered in plastic wrap which must be removed once in place.
2. Some awnings installed on the balcony are fixed and more practical. If you choose to shrink it is basically fabric, the quality is relatiVery lightweight and the price is quite cheap. However, relatively speaking, it may not be particularly effective at keeping rain out. If it is windy or rainy, it may fall, which poses certain safety risks. Balcony awnings can use solar panels as the main material, because solar panels are more durable than aluminum-plastic panels, more convenient to construct, and are not easy to fall, blister, fade, etc. after long-term use, so I strongly recommend everyone to choose solar panels.
3. In addition to solar panels, glass fiber reinforced plastics can also be used. Fiberglass reinforced plastic (FRP) is a fiber-reinforced plastic that mainly uses fiberglass as a reinforcing material. It remains very practical, has good resistance to corrosion and has along life expectancy. During the daily use of the battery life panel, special attention should be paid to the maintenance of the battery life panel, and waterproofing can also be carried out at the beginning of construction. This can significantly increase the life of the battery life panel and avoid. various unnecessary costs caused by subsequent replacement and maintenance. When installing, it is best to find a professional construction master to come and install it, so that the quality can be better guaranteed.
4. You can choose glass, solar panels, or durable panels to make your awning. These materials have a long service life, but when choosing materials, you must first understand the brand. Like the pressure-resistant plank blind, it's pretty good. It can also play a very good role in thermal insulation andUV protection, and it can also have a good earthquake resistance effect. Of course, to install the blind, you must first install a frame. The frame can be made of aluminum alloy, and the thickness can be at least 4mm. It can play a good fixing role, and the normal service life can reach more than 4mm. 20 years.
