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:Solar water heater can be added to the water, some people say that cold water than significant
Can add, add water is not directly added to the vacuum tube, is added to the container, the container will be added to the water and cold water,
Q:Solar vacuum tube bad effect
The vacuum tube is easy to break. Convenient or let the more professional to help you change it.
Q:How to identify the authenticity of the vacuum glass tube solar rain solar vacuum tube
Method of distinguishing true and false:The vacuum tube is the core component of solar energy, like a car engine, a human heart, if the thermal performance of vacuum tube is not up to, not 3 or 5 years, bought solar will become "cold water", is very painful
Q:Classification of solar vacuum tubes
According to the length is divided into 1.2, 1.5, 1.6, 1.8, 2.1, 2.3m, etc.
Q:Solar water heaters are not water in the summer, the sun will not have the water pipe explosion?
Solar energy is generally not a problem, pay attention to the general do not burn, to the solar water to be selected in the morning or evening, avoid high vacuum tube cold water and rupture.
Q:Solar water heater which is the best? How much is the price?
Two, according to your home water quality, climate conditions. The ordinary is inside the pipe on the water, if the water quality is poor or not clear, must choose not to take the water of the heat pipe. Scaling is ten times more difficult to clean. Of course, there is a light tube for the southern rainy days.How much money is really hard to say, because the pipe brand is different, the process is different, the price may be poor 2-3 times.
Q:Is the solar vacuum tube white is a quality problem
Hello, I am a 5 years of experience in the installation of specific technicians
Q:Installation of vacuum tube sealing ring for solar water heater
The barrel edge is sharp, easy to cut the skin, clean up after the new silicone ring front outward sleeve, a fixed point, and then slowly put the other screwdriver part is sleeved on the stainless steel barrel on it
Q:Who knows the solar water heater vacuum tube has a few? Respectively, single tube heat transfer maximum power is much
Currently on the market of the vacuum tube of Trinidad and Tobago, dazzling. Together with the sales staff that is at a loss, I talk about some personal opinions.Three high pipe: should be the first choice, what is the three high tube? Get hot, high temperature, anti - cold, is the three executives, some manufacturers lumenCopper plating, some manufacturers of aluminum tube, copper to a little expensive, from the economic point of view to recommend the use of aluminum tubes, aluminum tubes under the same conditions may be lower than the copper 1,2 degrees, in order to take the temperature of this twice the price I feel uneconomical
Q:How to dismantle the glass tube of solar water heater
The utility model relates to a vacuum tube type domestic solar water heater which is composed of a heat collecting pipe, a water storage tank, a bracket, and other related accessories. The principle of using hot water to float the cold water to sink, so that the water to generate micro circulation to achieve the required hot water.
