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 change solar tube
First put the water in the solar energy is not in each pipe and the water tank where there is a silicone rubber ring
Q:Solar vacuum tube what color is good
This type of consumer discrimination method of vacuum tube:1, the naked eye, the general tube and the appearance of the three high tube is dark blue, purple tube appearance is dark red2, in the sun from the tube to see, ordinary tube partial blue, three high tube partial red, purple tube is very red (pictured above)
Q:Solar energy is good or good vacuum tube
The tubes of the solar energy are vacuum, the purple tube is coated with purple,
Q:The water in the vacuum tube of the solar water heater is not available
That's true。 If you really want to use, you can slightly on some water, cold water mass, hot water light, you can put the tube hot water out of the. Be careful not to put too much water, otherwise the water will be cool.
Q:How to dismantle the vacuum tube of solar water heater
The vacuum tube, the tail tail tail pipe exposed (vacuum tube metal bracket bottom hold vacuum tube), the lower part of the vacuum pipe slightly upwards to lift off the tail exhaust pipe at the top, then counterclockwise turn pull down to seize the vacuum tube.
Q:Service life of solar vacuum tube
The whole vacuum tube, life in 15 years, the whole vacuum tube, no leakage, the diameter of 102MM, is the future direction of the heat collector, there are also some say 102MM tube tube do not go, but remember that the internal structure is not the same as the true vacuum tube is blue heat absorbing German imports of copper the whole structure, copper, vacuum thermal conductivity is 1000 times at room temperature.
Q:Solar vacuum tube is broken, how to change?
Determine the length and diameter of the original pipe, to the store to buy a solar energy as the specifications of the tubes, the rubber ring is sheathed on the pipe, the pipe with detergent, nozzle to be inserted into the water tank, and the pipe base head on the support bracket, fixed ring, OK.
Q:What are the types of tubes in the solar vacuum tube?
It can be divided into two kinds: full glass solar vacuum collector tube and glass metal solar vacuum collector tube
Q:How to distinguish the good and bad of the solar vacuum tube?
1: the comparison of the lighting area, the lighting area is good (thick pipe, tube length)2: lighting efficiency (light and heat conversion efficiency), you can ask the manufacturers, vacuum tube absorption and emission ratio, the general absorption ratio of 0.95, less than the reflection ratio of less than 0.05!
Q:How to remove the solar water heater?
Don't worry, now teach you how to dismantle:Because the vacuum tube quality is uneven, can not guarantee the process of demolition of glass tube will not be broken, so you must remember to wear gloves, a little thick cotton gloves, detergent and lubrication to smear some water pipe, and then hold the hands from the lower end of the vacuum tube tube, adjust the angle of push to the inside of the tank straight hole hard, a good grasp of the intensity, feeling suddenly stabbed, then left around, under the lubrication of joints, spinning slowly pulled out, until the pull of vacuum tube. How the feeling of such a wretched thing, huh, huh!
