 Our Advantages

Long Service Life
2.High Efficiency Solar Cells
3.Special Aluminum Frame Design
4.High Transmission, Low Iron Tempered Glass
5.Advanced Cell Encapsulation .


Solar System characteristic:
1. All Systems have LCD digital display which allows you to see the system working, (eg) Charge data, System voltage, Daily power consumption and temperature.
2. All type of BPS system both has AC and DC output.
3. All system have automatic switch , If mains power goes off the system will switch automatically over to battery power, When mains power resumes
 the system will switch back automatically. The batteries will resume recharging automatically.
4. All inverters are Pure Sine Wave inverters. This allows the use of Air Conditioners and refrigerators without any problem.
5. Each component has a single chip detector. Assembled by the IPM or IGBT of Mitsubishi
This protects the system from Overloads, Low Voltage and Under Voltage (alarm) Over Heating, Short circuit, Reverse Polarity.
6. Your system can be updated very easily. Just by adding extra components your system will increase power capacity.
7. Battery optional, you can purchase from us or locally.
8. Simple to install, just follow installation instructions.
9. Our System offers Cutting Edge Technology, State of the Art Quality with Greater Functionality than our competitors, at Competitive prices.

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: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: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:Can cold light make solar panels power
permanent, clean and flexible three major advantages of solar cells long life, as long as the sun exists, solar cells can be an investment and long-term use; compared with thermal power, Solar cells do not cause environmental pollution
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:What is the difference between solar panels and light panels?
The production of silicon requires that the stone be heated to become liquid, and the heating becomes gaseous crystals. During the need to burn a lot of fossil fuels and emissions of toxic gases silicon tetrachloride, this material has a corrosive effect on the skin. After pickling, pulling crystal, cut the side, finished a series of processes, more industrial chain. The cost of the finished product is too high. The energy consumption of making a solar cell requires solar cells to be equal in power generation for several years. The cost recovery period is very long.
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: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: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: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,
