2.Advantages of Poly Solar Cells

1). Tire-1 Solar Cells’ Manufacturer Quality Guarantee. With a complete and sophisticated quality government system, our Quality Management have arrived world’s leading place. Customer can receive Tire-1 Cells Maker’s Quality Standard Products.

2). Trusted Warranty. We can supply trusted after-sales service to our customer. If our cells are found not in conformity to the specification of manufacturer, or should the inspected quantity found in shortage, or should the packing found damaged, the buyer has the right to claim to the seller. The claim, if any, should be presented to seller within 30 days after cargo's arrival date to the port, together with related inspection report and photos issued and provided by a reputable independent surveyor such as SGS.

3). World’s Leading Manufacturer Equipment. We imported the newest and leading production equipment from abroad. Advanced equipment can guarantee the stable quality of cells. Auto production line can also save labor cost which will further cut our production cost.

4). Bulk supply: With the production capacity of 500MW, we can produce large quantity every month. This can satisfy most customer requirement.

 

3.Usage and Applications of Poly Cells

Solar cells are often electrically connected and encapsulated as a module.

Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting the semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage.

Connecting cells in parallel will yield a higher current;our solar cells have passed IEC Certification.

With high quality and stable quality. Our Cells can greatly improve the performance of Solar Modules.

Q:How to connect or use Solar Power Panels?
You will need help with this. Panels may or may not be 24 volt. If you can find a name tag, you can find out from the manufacturer's web site. Some folks hook them all in parallel. Mine are in series, to create 480 volts. the reason for going to higher voltage is to reduce power loss in the wiring. Even then, I used a wire size larger than recommended. The frames want to be interconnected, and wired to ground. The live conductors connect through disconnect switches to an inverter. The inverter is sized to the output of the panels. Where the utility allows net metering, the inverters are connected through a disconnect switch to the grid, which of course also feeds the house. Assuming you are on the grid, you will not need batteries. If outages severely impact you, you can have batteries. Counting against them is that they are costly, and use part of the power you generate, just to keep them charged. If you have batteries, it is usually best to rewire circuits so noncritical circuits are disconnected during outages. Leaving perhaps minimal lighting, fridge, freezer and critical medical circuits. Learn all you can from the Internet (try solar panels), and from the green search box above. Be sure to see if your state has a rebate program, and the conditions which it requires.
Q:Solar-Cell-panel help please?
I hope this will help you choose your charge controller / battery charger more effectively. Good luck!
Q:Research Paper on Solar Panels?
I'm a big fan of solar panels, and we even have an array on our house, but I would have a hard time supporting the thesis that solar panels are the best way to go green. Conservation and efficiency are. Using less is better than making more. If someone has the money for panels, but their house is poorly insulated, their money would be better spent on insulation. Pretty much anyone in the solar industry would agree. And solar hot water makes sense over a much wider geographical range than solar electric.
Q:How powerful are solar panels?
We think that powerful solar panels are good . As per their capacity they of-course needed many many solar panels, tks.

Q:Solar panel question?
4 in series for the 48V, a rack of 3 sets wired in parallel to give the current. (total of 2 panels)
Q:any one know about electricity solar panels?
The charger will accept whatever current is necessary from the solar panel up to 7A. It's not like the solar panel will force 2amps into the charger/battery -- the charger will control the current going to the battery. I question whether or not the 2V panel will actually charge the battery, though, because in order to charge a standard lead-acid 2V battery you need to have about 4.5 volts applied to the terminals. Perhaps the charger has a boost circuit -- I don't know without looking at it or knowing the brand/model number, etc. The timer must be 2VDC, but, if you only have a timer that is rated for 20VAC, you can buy a small inverter that will take 2V and supply the necessary 20VAC. An inverter rated for 20 to 50 Watts should be sufficient. These usually cost under US$25. .
Q:How energy-productive are solar panels, compared to natural gas?
Solar thermal in commercial applications is more productive than natural gas, taking in consideration the sun must be out. the reason being is when natural gas is exposed to a heating element(boiler, hot water heater) it loses efficiency. lets say solar thermal can produce a therm of hot water, but that would equal .2 therms of natural gas using an 80 percent efficient boiler. solar being close to 95 percent efficient. No boiler can do that. now when the sun goes down, fossil fuel can beat electrically stored energy, not stored steam energy in a thermal plant for example. but that all depends on efficient steam generators.
Q:how much energy does a 70x70 sq ft area of solar panels collect?
Considering capital outlays, such a system might never recover its initial investment. That's why we don't see such small photovoltaic plants popping up around the country - the economic case isn't there. One of the problems is that you would have to sell your electricity wholesale, at a ridiculously low price like 2 cents / kWh. If you were displacing electricity that you would otherwise use, then the financial case is different. Retail electricity could be 20 cents / kWh, 0 times as much, and you could get your money back over time, and start to make a profit. I've assumed you're in the US, with no special feed-in tarrifs. If you're in a country with a premium rate for solar-generated electricity, the business case could be very different.
