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: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 production of solar cells is mainly based on semiconductor materials, its working principle is the use of optoelectronic materials to absorb light energy after the photoelectricity in the conversion reaction, according to the different materials used, solar cells can be divided into:
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:What is the principle of solar panels to convert solar energy into electricity?
scientists have applied solar cells to space technology - communication satellites. At the end of the last century, in the process of human self-reflection, this clean and direct energy form for photovoltaic power generation has become more cordial, Not only in space applications, in many areas also show their talents. Such as: solar garden lights, solar power generation system, the village power supply independent system, photovoltaic pumps (drinking water or irrigation), communication power, oil pipeline cathodic protection,
Q:Single crystal solar panels and polycrystalline solar panels
Monocrystalline silicon cells in the laboratory to achieve the conversion efficiency of 24.7%. Ordinary commercial conversion efficiency of 10% -18%. Monocrystalline silicon solar cells because of the production process problems, generally its semi-silicon ingots for the cylindrical into, and then through the slice -> cleaning -> diffusion knot -> remove the dice -> the production of electrodes -> corrosion around -> Reflective film and other workers made of finished products. General monocrystalline silicon solar cells four corners for the fillet. Monocrystalline silicon solar cell thickness is generally 200uM-350uM thick, and now the production trend is to ultra-thin and efficient direction
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
Pre-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.
Q:What is the principle of solar panels work?
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: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,
