Product Description:

 

Benefits of Solar Power:

 

Following to RMI, Balance-of-System (BoS) elements, this is, non-module cost of non-microinverter solar modules (as wiring, converters, racking systems and various components) make up about half of the total costs of installations.

For merchant solar power stations, where the electricity is being sold into the electricity transmission network, the cost of solar energy will need to match the wholesale electricity price. This point is sometimes called 'wholesale grid parity' or 'busbar parity'

 

Specifications of Mono Solar Panel

 

Average pricing information divides in three pricing categories: those buying small quantities (modules of all sizes in the kilowatt range annually), mid-range buyers (typically up to 10 MWp annually), and large quantity buyers (self-explanatory—and with access to the lowest prices). Over the long term there is clearly a systematic reduction in the price of cells and modules. For example in 2012 it was estimated that the quantity cost per watt was about US$0.60, which was 250 times lower than the cost in 1970 of US$150.

Real world prices depend a great deal on local weather conditions. In a cloudy country such as the United Kingdom, price per installed kW is higher than in sunnier countries like Spain.

FAQ

 

Q: Do you have the CE, TUV, UL Certification?

A: We’ve already passed all the tests, and any certificate is available.

 

Q: Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other

A: Actually we are only manufacturer of solar panels, but we could try to source them for you in China if you need. We could provide you an optimal system design to instruct you how to install.

Q: What is your warranty system?

 A: For c-Si panel: 25years output warranty for no less than 80% of performance, 10 years output warranty for no less than  90% of performance. Free from material and workmanship defects within 5 years.

For a-Si panel: 20 years output warranty for no less than 80% of performance, 10 years output warranty for no less than 90% of performance. Free from material and workmanship defects  within 2 years.

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:Solar panels single crystal and double crystal in the rain which is easy to use
At present, monocrystalline silicon solar cell photoelectric conversion efficiency of about 15%, the highest reached 24%, which is all types of solar cells in the photoelectric conversion efficiency of the highest, but the production cost is so large that it can not be a large number of extensive And commonly used. 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 working principle of solar panels?
the inorganic salts such as gallium arsenide Ⅲ-Ⅴ compounds, cadmium sulfide, copper indium selenium and other multi-compounds as the material of the battery;
Q:Can cold light make solar panels power
Solar power generation There are two ways of solar power generation, one is the light - heat - electricity conversion, the other is the optical - electrical direct conversion.
Q:Can solar panels be connected directly to motor?
Power supply must be a number of individual battery strings, connected in parallel and tightly packaged into components.
Q:Composition and function of solar panels
Used to bond fixed tempered glass and power generation (battery), transparent EVA material directly affect the quality of the component life, exposure to the air in the EVA easily aging yellow, thus affecting the component's light transmittance, thus affecting the components
Q:Polycrystalline solar panels are good or single crystal solar energy is good
Polycrystalline silicon solar cell production process and monocrystalline silicon solar cell almost, but the polysilicon solar cell photoelectric conversion efficiency will have to reduce a lot of its photoelectric conversion efficiency of about 12% (
Q:The voltage and power problems of solar panels
In general, the charging voltage is 1.5 times the battery voltage as well, that is 12V battery pack, select the 18V solar panels just.
Q:What is the principle and structure of solar panels?
inverter: solar direct output are generally 12VDC, 24VDC, 48VDC. In order to provide power to 220VAC appliances, it is necessary to convert the DC power from the solar power system into AC power, so it is necessary to use DC-AC inverter.
Q:How many solar panels have ah?
But in reality, the need for solar panel power and solar charger to find a balance in the portability. It is generally believed that the minimum power of the solar charger can not be less than 0.75w, and the secondary power solar panel produces 140mA of current under standard light. In the general sunlight generated by the current at 100mA or so, if less than the secondary power charging current is too small,
