50 evacuated tube solar heating panels are generally classified as "large-capacity" or "commercial-grade" solar collectors and are suitable for the following locations:
Commercial buildings: such as hotels, hospitals, schools and factory hot water projects .
Large residences: families with multiple people or villas that require heated swimming pools
The installation size of a standard 50-tube solarcollector (φ58*1800mm) is approximately 4216mm x 1955mm, and the total absorber area (Gross Area) is approximately 7.7 square meters.
Each unit weight is approximately 120-130 kg without filling water. After the solar system is filled with water or thermal fluid, additional loads need to be considered for roof bearing capacity
The high-quality solar vacuum tube is made of high borosilicate glass 3.3, which has strong hail resistance (usually can withstand hail attacks with a diameter of 25mm)
Recommended optimal inclination angle for installation and maintenance: It is recommended to install according to the local latitude (usually ± 15 degrees of latitude) to obtain maximum light in winter
50-tube collectors are often combined in parallel. A 2000L hotel system usually consists of 4 groups of 50-tube collectors
Anti-scaling: In areas with hard water, it is recommended to use a heat pipe pressure-bearing solar collector to avoid scaling in the pipe and reducing efficiency.
How much hot water can a 50-pipe system produce every day?
Under standard sunlight, a set of 50-tube solar collectors can usually heat 400-600 liters of water to 55-70°C , If it is used purely for heat collection, its thermal power is enough to support a medium to large family or small hotel with 5-8 people.
If a vacuum tube breaks, will the entire system be paralyzed?
It depends on your system type.
Heat Pipe: No. Because water does not enter the vacuum tube directly, the system will still operate if one is broken, and there will be no water leakage .
All-glass tube type (Water-in-tube): Yes. Because water circulates inside the pipes, broken pipes can cause leaks and must be replaced immediately.
Will it still work in winter with snow or sub-zero temperatures?
Yes. The structure of the vacuum tube is similar to a "thermos", and its vacuum layer can effectively isolate heat loss. In an extremely cold environment of -30°C, it can still generate heat energy as long as there is sunlight .
In addition, the round heat collecting tube helps the snow to slide off automatically.
What are the roof installation requirements for this evacuated tube solar panel?
Load-bearing: The weight of the 50-pipe system can exceed 200kg when fully loaded with water. It is necessary to ensure that the roof structure is strong.
Area: Approximately 8-10 square meters of flat space is required (including pipeline maintenance clearance) . Orientation: In the northern hemisphere, due south is the best orientation, with less impact within 15 degrees east or west.
What is the typical lifespan of a 50-tube collector?
The design life of high-quality collectors is usually 15-20 years . The degree of vacuum inside the vacuum tube is key. If the "getter" coating at the bottom of the tube changes from silver to white, it means that the vacuum has failed and needs to be replaced.
Is it expensive to maintain? What needs to be done?
Very low maintenance.
Cleaning: In dusty areas, flushing the pipe surface with clean water every six months can increase efficiency by about 10%.
Inspection: Before winter every year, check whether the anti-freeze protection (heating tape) of the circulation pipeline is normal to prevent outdoor pipes from freezing and cracking.
Can I use it to heat a swimming pool or for floor heating?
Yes, but 50 tubes is usually too small for a swimming pool. It usually requires multiple sets of 50-tube collectors to be connected in parallel to achieve the desired effect.
Heating: 50 tubes can be used as an auxiliary heat source for underfloor heating systems, significantly reducing gas or electricity bills, but cannot completely replace a boiler due to shorter daylight hours in winter.
Are you considering integrating it with your existing gas boiler or heat pump system?
Looking into integrating a 50 tube solar collector with a gas boiler or heat pump, the main purpose is to use solar energy to preheat domestic hot water to minimize dependence on traditional energy sources, thereby saving energy costs and reducing carbon footprint. This hybrid system requires a dedicated dual-coil water tank and an intelligent control system
Integration with a gas boiler is one of the most common household hybrid solar solutions. The core idea is to let the solar water heating system be responsible for the main heating task, while the gas boiler only provides "supplementary heating" (Boost) when the solar energy is insufficient.
System configuration: You need an insulated water tank with Twin-Coil. The solar loop is connected to the bottom coil, while the gas boiler is connected to the top coil.
Work flow: Solar priority: Cold water enters the bottom of the tank, and antifreeze (usually a glycol mixture) heated by solar collectors passes through the bottom coil to preheat domestic hot water.
Refill on demand: Preheated water flows from the top of the tank. If the water temperature has reached the set temperature (for example, 50°C), it will be sent directly to the faucet; if the temperature is insufficient, the water flow will be directed to the gas boiler for secondary heating to reach the required temperature.
Compatibility: If the home has a traditional boiler with a tank, it is usually easy to integrate. But if it is a Combi Boiler, you need to use a special diverter valve and mixing valve, or replace it with a special model compatible with preheated water, because most tankless boilers cannot handle preheated high-temperature incoming water.
Energy saving effect: According to research, this hybrid system can save 23% to 56% of gas fuel
Integration with heat pump systems
Combining solar collectors with heat pumps is an efficient, fully renewable energy solution that is particularly suitable for underfloor heating.
System configuration: Similar to boiler integration, one or more large hot water storage tanks are also used. Solar energy provides a basic heat source, and a heat pump can use hot water (even low-temperature water) generated by solar panels as one of its heat sources to improve its operating efficiency (COP).
Work flow:
Time-sharing utilization: The solar system mainly produces high-temperature hot water during the day and stores it in the water tank. Working together: At night or on cloudy days, the heat pump starts. The heating efficiency of the heat pump is greatly affected by the external temperature. Using solar-preheated water can increase the inlet water temperature of the heat pump, thereby improving the overall system efficiency.
Space heating: For floor heating, solar hot water can be used directly to heat the floor loop, but a mixed water loop is required to ensure the right temperature (to avoid overheating the floor)
