FAQ:

1. What is the brand of this 300W mono photovoltaic Solar panel?

RISUN, we are the manufacturer of this panel, OEM service is available, as well as wholesale trades.

2. About the glass we use for the front of the panel:

---3.2mm tempered glass , light transmittance up to 95%.
3. Does it meet Europe Standards for Solar Energy ?  
This is TUV approval products, all producing procedure strictly accords with TUV&UL.
4. What is the Efficiency level ?
--- Between 16-18.9% for solar cells.

5. What's the nominal Voltage?

    18V. So it can charge 12V battery. If you need 36V to charge 24V battery, just loose the cable from the solar panel and connect them in series. If you're not sure what to proceed, just contact us.

6. How to make the payment?

 20% advanced in deposit by T/T or L/C, the rest payed after receiving B/L copy.

7. How long is the shipping time?

 5-15 days after receiving deposit by the first available vessel to your country.

Q:What is the principle of solar panels work?
optical - electrical direct conversion method is the use of photoelectric effect, the solar radiation can be directly converted into electrical energy, optical - electrical conversion of the basic device is the solar cell. The solar cell is a device that converts solar energy directly into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode turns the solar energy into electricity. Current. When many batteries in series or in parallel can become a relatively large output power of the solar cell array
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
Because the MPPT controller has a wider input voltage range, it can also convert multiple voltages into current charge and better protect the battery.
Q:What is the principle and structure of solar panels?
solar controller: the role of solar controller is to control the working state of the entire system, and the battery played a charge protection, over discharge protection role. In the larger temperature difference, the qualified controller should also have the function of temperature compensation. Other additional functions such as light control switch, time control switch should be the option of the controller;
Q:How many solar panels have ah?
Classification of solar cells: Currently on the market of solar cells into amorphous silicon and crystalline silicon. Crystalline silicon can be divided into polysilicon and monocrystalline silicon. From the photoelectric conversion efficiency of the three materials is: monocrystalline silicon (up to 17%)> polysilicon (12 ~ 15%)> amorphous silicon (about 5%).
Q:Why can not the solar panel load directly?
Solar panels (also known as solar modules) are the core of solar power systems and the most important part of solar power systems.
Q:What is the working principle of solar panels?
the material is easy to industrial production and material performance and stability.
Q:What is the principle of solar panels to convert solar energy into electricity?
When the light is irradiated on the surface of the solar cell, a part of the photon is absorbed by the silicon material; the energy of the photon is transferred to the silicon atom, so that the electrons are moved and the free electrons are formed on both sides of the P-N junction to form a potential difference. When the circuit is used, the current will flow through the external circuit to produce a certain output power. The essence of this process is the process of converting the energy of the photon into electrical energy.
Q:Solar panels single crystal and double crystal in the rain which is easy to use
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% (July 1, 2004 Japan Sharp market efficiency of 14.8% Of the world 's most efficient polysilicon solar cells).
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.
