5. FAQ

(1) Which collector is the best value for money?
Rather than looking at just peak efficiency levels when comparing solar collectors, cost per unit of energy produced is much more logical. For example: Although collector A may be 20% more efficient than collector B, if collector A is 30% more expensive, then in fact collector B may be a better choice, as per kWh of energy produced per day it is cheaper. When payback time is of concern, not only price per kWh of the product is important, but also of the end system.

 

(2) Can this solar collectors be used for a large scale hot water production?
Yes. This solar collectors can be connected in series or parallel to provide large scale hot water production for a commercial settings such as a school, hotel or office building. There is really no limit to the size of the system, however collectors must be installed in banks of no more than 150 tubes (in series), otherwise the water may boil.

 

(3) What maintenance of the solar collector is required?
Under normal circumstances no maintenance of the system is required. Due to the shape of the tubes regular rainfall and wind should keep the tubes clean. Should a tube even be broken it should be replaced. This, however, is an inexpensive and easy job. Any "handy" person can install a new tube (while adhering to local health and safety regulations). Sidite solar collectors can operate with several broken tubes, however the efficiency will be reduced slightly.

Q:Is solar collector directly using solar energy?
Most of the solar water heaters are equipped with electric auxiliary heating function, when the rainy weather will automatically start when the electric heating function.
Q:What is the principle of thermal conversion of solar collectors?
The most common solar collectors are non-concentrating flat type collectors. Its heat absorber body is basically flat shape, the area of heat absorption and the lighting area is approximately equal, its structure as shown in Figure (a) is the use of greenhouse effect of non-concentrating type collector. Enriched CO2 in the greenhouse can improve the greenhouse effect. Condenser type collector using the principle of focusing, that is, the use of light reflection and refraction principle, the use of reflectors or refractors to change the direction of the sun, the sun focused on the heat sink in the small area of the heat absorber, increase the unit area Of the radiation intensity, so that the collector to obtain a higher temperature.
Q:Solar collectors and tank water can not cycle what is the reason
Pipe clogged. If the exclusion of the other two cases, then the possibility of a large pipe block, including the pipeline frozen, debris blockage are possible, if the pump is easier to burn the pump, need special attention.
Q:With the tonnage of solar collectors and air to hot water which power consumption
resulting in no hot water in the rain and snow weather; and air to hot water works relative It is not affected by the sunshine, theoretically can be used throughout the year.
Q:How can solar collector system prevent wind?
A solar collector is a device that absorbs solar radiation and transfers heat energy to the heat transfer medium.
Q:Condensation type solar collectors and non-concentrating heaters
Solar collectors can be classified by a variety of methods, for example: according to the type of heat transfer refrigerant, according to enter the mouth of the solar radiation is to change the direction;
Q:Flat solar collector how, flat solar collector working principle introduced
pipe installation, not in the structure of the beam column, the seismic wall of the dark column, the end of the pier at the tube. Through the roof, the wall should be timely embedded casing, to avoid the waterproof insulation has been done on the roof hole
Q:Vacuum tube for solar collectors
Good insulation: heat pipe has a one-way heat transfer characteristics, so that hot water at night will not heat down the heat pipe to the surrounding environment.
Q:Where is the solar collector installed in the building?
There are flat-plate collectors and vacuum tube collectors, as well as medium-high temperature trough collectors in different forms, the installation site requirements are not the same; but generally according to geographical location, towards the basic south.
Q:Flat solar collector is a good blue film, or good black chrome? It is best to specify.
However, the current plating black chrome process, the current density (15 ~ 200A / dm2), the solution conductivity is poor, plating will produce a lot of Joule heat, cooling and ventilation need to maintain normal production. In addition, the black chrome plated in the non-copper pieces, you need to pre-copper, and then plating bright nickel, and finally black chrome, the higher production costs.
