Advantages of wall-mounted solar energy for balconies
1. The wall-mounted solar power for balcony is equipped with a pressurized water tank. This water tank can be connected. to tap water, and there will be no problem of traditional solar water supply and the water pressure is 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. Photoelectricity is used together. If there is no sun, electric energy can be used for heating, so you can enjoyhot water in winter without sun.
Disadvantages of wall-mounted solar energy on balconies
1. High price and high installation cost.
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.
The above quotes are taken from the Internet and are for reference only. The achat actual will prevail.
Advantages: 1. Save space, the collector and water storage tank are separated, solving the installation problems of high-rise users;< /p>
2. The collector can be hung on the balcony or exterior wall to reduce wind resistance and look beautiful;
3. The collector is not directly connected to the water. in the duct Instead of contacting, the thermal energy is transmitted to the condensing end through the conductive liquid, and the condensing end conducts the thermal energy into the duct without generating scale
4. The conductive liquid is a professional antifreeze agent, can be used normally under low temperature conditions, and can produce heat in two minutes under the sun
5. uses polyurethane foam as the insulation layer, with better insulation performance;
6. THEWater storage tank is equipped with an auxiliary electric heating system even if the auxiliary system is turned on. when the sun is insufficient, the water heater can be used normally;
7. The water storage tank is made of enamel coating structure, which isolates water and electricity, making it safe and reliable;
8. The whole system is operated under pressure and there will be no storage. The water tank will burn due to lack of water, so it is safer. to use.
Disadvantages: 1. There are some restrictions on the orientation of the building.Requirements;
2. There are certain requirements for the feed water pressure
3. Water heater .
