 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.

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:Questions about solar panels?
There are several web sites you can search for and they will provide the answer on how big of a PV Solar Array you would need for your house. Several things need to be known, such as square footage of the home, how well the home is insulated, etc. The panels come in all sizes and wattage's depending upon application, so yes they should all fit on the roof. If you have a small roof get PV panels with higher wattage's. Yes, they will work in the northern latitudes but not as efficiently as near the equator. You might need more PV panels to make up the loss in power from the sun hitting at a lower angle. Generally, all you will need to do is periodically clean the glass covering of the PV Panels to get maximum sun light on the PV cells. In my region, near the 45 th parallel, a 600 square foot home with six inch insulated walls and R40 attic insulation can purchase a PV panel system for around $40,000. That includes the equipment to tie it into the power grid and the meter to measure how much you supply the grid during the day and how much you draw from the grid at night when the sun isn't shining. There are tax credits for retrofitting an existing home, but mostly it is new homes being built that are having the PV panel systems installed so the cost is added to the mortgage and the return on the investment is paid off over the life of the System (about 5 to 20 yrs.)
Q:Have a question about mobile homes and solar panels!!!?
I was in debt up to my eyeballs, and I needed help fast, so I looked to some free online programs. I had tried so many that were scams, but I finally found one legit one! In two months, I paid off $3000 of my debt.
Q:What is the cost of Solar Panels?
That okorder.com
Q:SOLAR ELECTRICITY PANELS DO THEY WORK?
Why of course. Just buying them is the big buzz. Companies are doing thousands if not millions of dollars a month only by selling Solar Panel. I did a little search and I found that it costs 7000$ to install solar panels for an average roof. If you're a hardcore green, then Bon Appétit, I'm not preventing you to buy it. All I'm just saying is that it'll take months if not years to get that money back. It is good for electricity, and I saw it worked on a company building called Better Place, so save the world!
Q:How to make 2V 4.5A solar panel from solar cells?
To increase current, you connect the cells in parallel. But I think you really mean you need 4.5 watts rather than 4.5 amps of current. For an RC car, 4.5 amps would be huge, literally a regular car battery. So I think you mean you need a 2v, 4.5w panel. That would make more sense for an RC car battery. I went on OKorder and bought a 2v, 5 watt panel for about $30.
Q:When I make a solar panel what kind...?
First of all you seem to be talking about making a solar photovoltaic panel instead of a solar thermal panel. Most solar panels will produce DC electricity. Your house uses AC electricity. You can set up the solar photovoltaic panels to send their current to charge a battery bank and then you can tap into that battery bank and send the power to a voltage inverter to change the power to AC. The better inverters will do a better job of this. The system has to be matched and sized properly. If you are not familiar with electrical work you should have someone who is more knowledgeable help or do the work. Good luck with your project.
Q:How do you make a solar panel?
There are many kinds of solar panels. Please specify single crystal, poly crystaline, gallium arsenide, thin film, or water heating solar panel. How much detail do you need? Are you actually making one or just writing a report? If you expect a meaningful answer you need to provide background information.
Q:Could solar panels contribute to global warming?
As far as any albedo effects from solar panels, the entire USA only occupies a little over 2% of the worlds surface, if you painted the USA black, it would have a minimal effect on globally averaged temperatures. The mining of the resources alone required to cover the entire USA with solar panels would devastate the planets ecosystem. . .
Q:where do you get little solar panels?
I bought mine from OKorder. They were from a top seller and arrived in better condition than I expected. They are 3 X 6 and have an output of .5 volts .7 watts. You will need other items as well blocking diodes, charge controllers as well as tabbing ribbon and buss wire. Learn about other components you may need at the website below. There is also an OKorder link at the bottom of the page.
