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:who would win in this battle?
hmmmmm trees would squash em and solar pannels would electric cute em............... :)
Q:what is the volts of 75watts solar panel?
Many of the panels used on homes are designed to produce 2 volts DC. 0 of them wired in a series would produce 20 volts DC. An inverter is used to change the DC voltage to AC. The other aspect of electricity is amperage. With electrical units wired in series the voltage is added. When they are wired in parallel the amperage is added. The Volts x Amps produced will give you the wattage. A wise homeowner will examine their electric bills or the equipment used to determine their demand. They will consult tables that let them know how much sunlight their area receives each year as this will alter the rated performance of the panels. Then they will try and determine how much of the demand they want to fill. 80% may be economical. Then they also want to determine what they will do with excess electricity that may be produced during the summer months of intense sun and how they will supply the shortfall of low sun winter months. From all this they will determine the number of solar panels they need to purchase.
Q:what is solar panel? full description needed?
Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.
Q:Does anybody know if there are any courses for solar panel installation, and/or what trades you need for this?
If you are in the UK, then the Centre for Alternative Technology courses (CAT in Wales) have had some great feedback.. .. A lot of companies are actively recruiting and offer training courses as part of their induction. Have a look at the bigger ones recruiting near you.
Q:How much does it cost a factory to make a solar panel?
First Solar recently announced that their costs to produce panels dropped below $ per watt. I don't know how much of that is accounting tricks. Of course, that doesn't mean that they would sell panels for that price - any capitalistic company is expected to drive the price up to what the market will bear. Crystalline silicon panel producers are coming in at about $2.50/watt right now for the best of them. But again, the selling price is what the market will bear.
Q:Help with Home Solar Panel System?
Himin Solar can help you design and install home solar panel system.
Q:SOLAR Panels?
$8,000 invested at 5% interest would pay you $900 per year for the rest of your life. If you spend $40 per month and would save 25% of that, you would save $420 per year. To be fair, the savings would creep up with the electric rates but this would be off-set by maintenance cost and equipment attrition.

Q:Solar Panel Help, Trying to go green.?
I had a system installed last year and am very happy with it so far. When I was getting quotes from companies we used a 3 year usage history that I was able to get from my utility. I live in an area that allows me to sell back my excess or let my meter run backwards, which really helps reduce costs. The amount of energy you use and can produce will vary during the year. I had monthly usage under 800 kwh and months over 2000 kwh. I have become more aware of my usage and have made adjustments to appliances and habits to cut my usage down. I installed a 3.74 kw dc system. On average in the summer I generate 35 kwh per day and in the winter I averagae around 2 kwh per day, but I've seen days as low as 2kwh. I don't see the benefit to hooking up a system to specifice appliances for 2 reasons. Your a/c doesn't run non stop, so the energy you produce when the system cycles off is lost. You only produce electricity when the sun is shining on the panels. If you have a cloudy day or it is hot after the sun goes down, you will need to still use household energy. My system doesn't zero out my bill, but it reduces it by about 75% in the summer and at least 50% in the winter. My bills were over $200 many months, my highest summer bill was $20 and highest winter bill was $35. My system cost $26K (less than my pool or hardwood floors), I got a $0K rebate from my utility and a $2K federal tax credit. The fed. tax credit has increased this year to 30% of the total installed price. I should break even in 6-7 years and save well over $50K over the life of the panels.
Q:Solar Panel questions...?
the first person is absolutely wrong. A 200 watt panel is $000US. By the time you buy mounting systems, wire, inverters, electric panels, interconnects, labor and permits/inspections, the cost is about $7/watt. if you use 700 kw-hr (please look at the units, you use kw-hr NOT kw) per month that 24 kw-hr per day. in your area, a pv system will supply about 4 hours at peak production of the panels, so you will need 6kw in panels, that's about 30 panel or $42,000 in equipment.
