Now is a great time to go solar and harvest the power of the sun. Here is our top ten list of the benefits to installing solar power:

1, When installed, solar energy is free – no resources are consumed 
2, Help to lessen our dependence on heavily polluting coal power stations 
3, Fossil fuels can't last forever, future generations will appreciate the effort 
4, You are gaining energy independence - add battery backup power for even greater energy security 
5, The cost of electricity is only going to rise – insure against that rising cost 
6, Quality solar power and water adds value and appeal to your home 
7, Solar PV systems are easily upgraded in future - aim to make your house a net energy producer! 
8, Solar panels offer a long lifetime of low maintenance service, maybe 30-40 years 
9, Your friends will think you're great! 
10, You'll feel great for doing your bit for the environment!

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 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 market share and a slight increase, and now the market to see the majority of single-crystal silicon cells. Monocrystalline silicon solar cell silicon crystal is very perfect, its optical, electrical and mechanical properties are very uniform, the color of the battery is mostly black or dark, especially for small pieces of small pieces of consumer products.
Q:What is the difference between solar panels and light panels?
The highest conversion efficiency in the laboratory is 24.7%, and the efficiency of the scale is 16%. Polysilicon conversion rate of 14% -15%. Amorphous silicon conversion rate of 12%. Silicon film conversion rate of 9%. Silicon solar cell is the main raw material of silicon, silicon is an extremely rich element of the earth, almost everywhere there are silicon, can be said to be inexhaustible, with silicon to create solar cells, raw materials can be described as no shortage.
Q:Can solar panels be connected directly to motor?
The sun is irradiated on the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region. The electrons flow from the p region to the n region, and the current is formed after the circuit is turned on.
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
3, charge 12V battery when the power is really small, if it is a normal controller, then the equivalent of 18V voltage in the charge, probably 18 x (240 / 30.2) = 143w solar panels.
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:What is the principle of solar panels work?
The sun is irradiated on the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region. The electrons flow from the p region to the n region, and the current is formed after the circuit is turned on. This is the photoelectric effect of the working principle of solar cells.
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,
