Product Description:

Solar panel refers either to a photovoltaic (PV) module, a solar hot water panel, or to a set of solar photovoltaic modules electrically connected and mounted on a supporting structure. A PV module is a packaged, connected assembly of solar cells. Solar panels can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available, based on thin-film cells.

Electrical connections are made in series to achieve a desired output voltage and/or in parallel to provide a desired current capability. The conducting wires that take the current off the modules may contain silver, copper or other non-magnetic conductive transition metals. The cells must be connected electrically to one another and to the rest of the system. Externally, popular terrestrial usage photovoltaic modules use MC3 (older) or MC4 connectors to facilitate easy weatherproof connections to the rest of the system.

Bypass diodes may be incorporated or used externally, in case of partial module shading, to maximize the output of module sections still illuminated.

Some recent solar module designs include concentrators in which light is focused by lenses or mirrors onto an array of smaller cells. This enables the use of cells with a high cost per unit area (such as gallium arsenide) in a cost-effective way.

Q:How to solve this problem? Thanks
At this point, one hand holding the tail of the vacuum tube to hold the tip of the tail, the other hand in the 1/3 vacuum tube, the force should be uniform and keep the direction of force and coaxial nozzle, the vacuum tube is inserted into the water tank pipe hole, this can be inserted into a vacuum tube, the tail support after alignment then pull out, until the vacuum tube and the support to rely firmly, retaining ring close to the outer wall of the water tank.
Q:How to know whether the solar vacuum tube burst
During the day, the temperature rise of the solar water heater is a slow process. To the night, the temperature is slowly cooling. Vacuum tubes do not suffer from severe temperature changes.There are now 47 tubes and a total of 58 tubes. Length is not necessarily the same.First measure the size or bring the broken pipeInstallation is nothing special is to put the pipe into the water tank to poke a little, and then take off the bottom of the pipe support (or the tube out of the tube)Then pull out. Do not throw the silica gel on the top
Q:Solar water heater for a long time how to deal with?
If the home to buy solar energy, temporarily do not have to use it, it is recommended that you use blankets, carpets or quilts cover the vacuum tube to avoid the sun, so there will be no problem.
Q:Solar water heater vacuum tube in the summer without water easily broken
If it weren't for the summer, the temperature would not be higher, not to worry about the problem. In the summer is approaching, we must do a check on the water heater, a maintenance, to increase the service life and life.
Q:Solar vacuum tube can not produce steam
It can be a series of solar collector system in use, which is suitable for high temperature solar thermal power generation device, solar boiler, solar air-conditioning, solar energy, solar greenhouse aquaculture engineering project, large-scale solar biogas engineering application in constant temperature.
Q:The red sun is how much a piece of solar vacuum tube
Solar water heaters unless the tank or stent, the rest can be used in general
Q:What is the solar vacuum tube installation skills?
Since the birth of life on earth, mainly to the sun to provide heat radiation to survive, and since ancient times, people also know how to use the sun to dry objects, as well as the production of food, such as salt and salted fish, etc.. In the case of dwindling fossil fuels, solar energy has become an important part of human energy use, and has been developing. There are two ways to use solar energy, such as photothermal conversion and photoelectric conversion. The broad sense of solar energy also includes wind energy, chemical energy, water, etc..
Q:Solar vacuum tube can be removed once
The water is clean, the vacuum tube and the water tank is connected with a rubber ring, buckle down (if very tight, can be softened with hot water
Q:Solar vacuum tube removal 10Move away from solar energy, vacuum tubes do not know how to dismantle
Recommended to find the installation of manufacturers to help dismantle or find a professional maintenance personnel
Q:How to replace the solar vacuum tube? Looking for someone to change too expensive
The lubricant into the vacuum tube and the water tank in the gap (must be shot in the bottom of the sealing ring, around the shooting). Then put on rubber gloves for the labor (anti vacuum tube rupture hands turn firm) a vacuum tube, go up
