Poly Solar Panel 285W A Grade with Cheapest Price


Product description


60 cell multi-crystalline solar module. 40mm natural anodised frame. IP65 rated Jbox, 1m solar cable and a pair of MC4 connectors.TÜV SÜD,SABS ISO 9001:2008 certified.

Nominal voltage refers to the voltage of the battery that the module is best suited to charge; this is a leftover term from the days when solar modules were only used to charge batteries. The actual voltage output of the module changes as lighting, temperature and load conditions change, so there is never one specific voltage at which the module operates. Nominal voltage allows users, at a glance, to make sure the module is compatible with a given system.

Open circuit voltage or VOC is the maximum voltage that the module can produce when not connected to an electrical circuit or system. VOC can be measured with a meter directly on an illuminated module's terminals or on its disconnected cable.

Chemicals such as Boron (p-type) are applied into the semiconductor crystal in order to create donor and acceptor energy levels substantially closer to the valence and conductor bands.

The basis of producing solar panels revolves around the use of silicon cells.[28] These silicon cells are not efficient enough in their current state and can only convert solar energy [29] in to usable power at a rate of roughly 10-20 percent.[30] In order for solar panels to become more efficient, and therefore more useful in the future, researchers across the world have been trying to develop new technology to make solar panels more effective at turning the sun in to energy.[31]

Product feather

solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.

A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricityin commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 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, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Q:Why can not the solar panel load directly?
Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.
Q:What is the working principle of solar panels?
Based on the above considerations, silicon is the most ideal solar cell materials, which is the main reason for solar cells to silicon-based. But with the continuous development of new materials and related technology development, to other village-based solar cells are increasingly showing attractive prospects.
Q:What is the main material for making solar panels?
You can also according to their own needs, according to the power to buy a good package of solar photovoltaic products.
Q:What is the principle of solar panels to convert solar energy into electricity?
optical cable communication pump Station power, seawater desalination system, urban road signs, highway signs, etc. Europe and the United States and other advanced countries will be integrated into the photovoltaic power generation system and remote areas of natural village power supply system into the development of the combination of solar cells and building systems have been formed industry Trends
Q:Single crystal solar panels and polycrystalline solar panels
Monocrystalline silicon solar cells are mainly made of monocrystalline silicon, compared with other types of solar cells, monocrystalline silicon cell conversion efficiency of the highest. In the early days, monocrystalline silicon solar cells occupied most of the market share, in 1998 after the retreat of polysilicon, the market share accounted for second. Due to the shortage of polysilicon raw materials in recent years, after 2004,
Q:What is the difference between solar panels and light panels?
Silicon solar cells are divided into monocrystalline silicon, polysilicon, amorphous silicon, silicon thin film solar cells and several. At present, the world's most widely used solar cells are silicon solar cells, in large-scale applications and industrial production is still dominated by the penetration rate of 90% or more, monocrystalline silicon solar cell photoelectric conversion efficiency of the highest technology is also the most mature.
Q:Can solar panels be connected directly to motor?
Solar panels (also known as solar modules) are the core of solar power systems and the most important part of solar power systems.
Q:Polycrystalline solar panels are good or single crystal solar energy is good
. Since monocrystalline silicon is typically coated with tempered glass and waterproof resin, it is rugged and durable for up to 15 years and up to 25 years.
Q:What is the principle of solar panels work?
light - heat - electric conversion method through the use of solar radiation generated by thermal energy, usually by the solar collector will absorb the heat into the refrigerant refrigerant, and then drive the turbine power generation. The previous process is the light-heat conversion process; the latter process is the thermo-electrical conversion process.
Q:How many solar panels have ah?
However, crystalline silicon (monocrystalline silicon and polysilicon) in the weak light is basically no current generation, amorphous silicon weak light type (in low light energy is rarely). So a comprehensive view, it is appropriate to use monocrystalline silicon or polycrystalline silicon solar cell materials. Second, the choice of solar cells 1, we buy solar cells, the focus is on the power of solar cells, in general, the solar panel power is proportional to the area of ​​solar chips.
