 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:0W solar panel can use on what?
0w Solar Panel Kit
Q:i am asking about the solar panels?
First of all, make sure that you are taking readings in the dark (with the solar panel indoors and covered). 0.433 is a reasonable forward voltage for a Schottky diode. Ideally, it diode should read open one way (possibly OL for your meter), and 0.4 the other way. If it's reading OL both ways, the diode is bad. You can either unsolder it or cut it out and verify that it is bad.
Q:Why are solar panels made from silicon and not magnesium?
Silicon is a very good conducter. Probably the best for electricity.
Q:how much money does solar panels save?
I can tell you for a fact you can save money with solar panels. I have a system. I have a 3.74 kw dc system which cost $26K, I got a $0K rebate from my utility and a $2K fed tax credit. I will break even or get ROI in 6-7 years. My system generates about $2K of energy per year. The benefit of a school is most of the energy will be produced during the time that the students are using the facility so you may see a better return. I still use much of my energy when the sun goes down. All businesses get a 30% fed tax credit when they install a system, and many states offer larger rebates to businesses. There are many factors that will determine the efficiency of the panels, my orientation isn't ideal so that drops my production a little. Shade can reduce the number of hours a panel can produce. The number of hours of sunlight and the number of days it is cloudy can affect production as well. Your utility policies can have an economic impact, not all utilities allow the meter to run backwards or buy back the excess energy you produce, most schools are out of session during the longest most productive days. The biggest problem for solar is the large initial payment, without grants or loans it is unlikely a school would have the money to put up a large system. There is no need to zero out the bill, even a partial system can save money.
Q:so what do you all think about solar panels? are they worth it?
They are absolutely worth it. I had a town house in Boston with solar panel shingles and they were able to supply enough energy for me to feed back the grid-- literally making money off of them. I am building a very large home in the suburbs now and we are doing solar shingles on that. Our contractor estimated that with our geotherm heat pump and energy efficient lighting we should still be able to throw back more energy to the grid all year round! As for leasing it is not worth it. For one thing, most leasing contracts prevent you from selling your energy to the grid yourself but rather they take a cut. But a bigger issue: the government gives you a tax credit on solar panel installations but only if you purchase them! I did the math myself the first time I did solar panels and with the tax credit I saved 25% over leasing. Something else to consider is that with your own panels you can connect a variety of other systems to your home and modify them as needed.
Q:Solar Power Question?

Q:How can a solar panel work for me?
Yes, it can. Now what do you expect out of it? It can reduce your electric bill by some amount. That amount depends on how many solar panels you install and how sunny your days are. You have to pretty much cover a roof to get a substantial electric reduction. There are 2 companies where I live that have installed solar panels and covered most of their roofs with them. They've reduced their electric bill by about 30%. It's expensive to do this. Don't expect a fast pay back. In fact you may save more by using solar heating panels for hot water than by using solar electric panels. I think it's cheaper as well.
Q:Where to get or find information on solar panels?
Many companies are regional, so it is hard to give a specific company name. The best thing to do is look in the phone book for solar contractors. You can buy any size system you want it to offset all or a portion of your bill, there may be rebates and you will be able to receive 30% tax credit if you do it this year. Make sure to get an estimate on how soon you will break even. You will also be able to get a more accurate quote if you know at least year usage history. You should be able to get that info from your electricity provider.
Q:Electricity question about solar panels?
A 500 watt water heater is very small. Most are over 5000 watts. But even a water heater that small would not heat water with a 95 watt solar panel. Inverting the 24 volt to 20 volt would still give you 95 watts of power. A little short of the 500 needed. Sorry. Solar is cool but not practical for large loads unless you install more panels.
Q:Increase Solar Panel Efficiency?
If you have a way to keep silicon panels cool, that really helps. On a hot summer day, our array was down 20% in production. I sprayed a hose to wash the panels, and for a few minutes, the power spiked to 20% ABOVE normal. The usual thing to do is mount the panels exposed to the wind if you can, or at least 8 off the roof otherwise. A few lucky souls with access to free stream water on their property have been known to use water cooling under their panels.
