Characteristics of Solar Panel

I Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.

II Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

III EVA and TPT: Using high quality EVA and TPT to prevent destroying and water

IV AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.

V Junction box: Multi function junction box with water proof.

VI Long lifetime: ≥25 years; Less power decrease.

VII Good performance of preventing from atrocious weather such as wind and hails.

VIII Resisting moisture and etching effectively, not effected by geology.

Currently,We have 250w-300w solar panel stocks in Both West and East Coasts made in Vietnam,India,Korea,Malaysia and Japan.Meanwhile,we also arrange production line in Wisconsin,USA.If you're interested,please contact us soon.

Thanks for your time.

Q:thermodynamic question that includes heating water with solar panels?
Here's a typical 4' x 8' collector rating. 40 degree latitude would be a cool climate, so you look at row D, water heating in a cool climate. Probably take the middle rating, mildly sunny day, and it is 0,000BTU per panel per day (it's 9,000 on a sunny day). 38,700 BTU / 0,000 BTU = 3.87, they'd need about 3 to 4 panels. If you used the sunny day number, you'd only need 2, but 3 is more realistic, as it is not always a sunny day.
Q:The effect of colored light on a solar panel?

Q:How do solar panel power systems work?
The panels soak up the energy from the sun and then convert the energy into power, electricity, etc. They can also store a lot of energy so that we still have power on cloudy days. Does that help? Without more info, its hard to get more specific.
Q:How to build a solar panel for lighting/heat source?
Some people that have advanced technical skills can even try to build their own solar panels to save money. In case you decide to go with this option you should know that today is fairly easy to find lot of literature about building your own solar panels which of course makes things easier. Still I would recommend this option to people without advanced technical skills. renewableenergyarticles.blogspot....
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:how much energy does a 70x70 sq ft area of solar panels collect?
This question is too generalized to answer. Are you australia? If so ergon buys the power back at 45cents a KWH which is 3 times what they sell it for.(this is guaranteed for 20years) We have a 2.4kw system and it will take approx 5years to pay itself off. Once carbon trading is in full swing electricity costs are going to go up by 40%, then obviously it will take approx half the time.
Q:Solar Panel Question...?
The best way to find out is to determine the wattage of each piece of equipment you want to use and how many hours you want to use those pieces of equipment. Finally, calculate the total number of Watt-Hours you need at minimum. Then you need to research solar panels or mobile wind mills (they need to be pretty huge to get a decent amount of energy I think, so solar power is probably the way to go). You will need to figure out the efficiency of the solar panels, the size of the array, how you will turn it or if you will turn it at all (to face the sun to get the maximum energy input, or maybe to use mirrors so you don't have to turn it. Once you find a good configuration for your mobile kitchen, you need to calculate if the Watt-Hours you will generate on an average day (with average weather) is enough to power the equipment whose energy requirements you previously calculated. Then you have to keep in mind that some days will have no sun, and you may not be working on some days, but you can still capture sunlight. For each case, a large battery array will be required. If you had a guage on that array, you could also hook it up to the a small generator in case you need immediate power. It's an eco-friendly process, but the initial cost is high and it requires a lot of research and planning. This is why most people do not do it--not because they don't want free energy from the sun, but because it's not easy to start collecting that energy in an efficient way. Sorry I couldn't give you more specific numbers, but a solar panel sales agency should be able to estimate whether or not you could do it (they'd probably set it all up for you too). ^_^
Q:how long does it take for a solar panel to make one watt?
Well, a 5 Watt solar panel running for an average of 2 hours per day, (there will be clouds), will put 5 * 2 = 80 Watt-hours into the battery. Assuming your inverter, (to convert 2 Volts D.C. to 20 Volts A.C.) runs at 00% efficiency, that will only supply power to run the grill for about 22 minutes a day. In the real world, neither the battery nor the inverter will work at 00%, to your actual heating time will be significantly less. If you get about 0 more of those 5 Watt solar panels, that would give you about 50 Watts * 2 hours or about 800 Watt-hours which would more than cover what you want to do. The next problem is getting an inverter which will handle a 700 Watt load. They can be found at auto supply houses and the larger truck stops. (They are popular with semi-drivers.) Note however, that a standard car battery will have to supply about 55 Amps, which means you will have to use some really heavy wire, like # 4 or # 6 welding cables to connect the inverter to the battery to minimize losses. P = 700 Watts E = 3 Volts I = 53.84 Amps R =
Q:Solar Panels, anyone?
Unless you live in an area with a very high UV index, like Las Vegas for example, solar panels are not cost-effective. You definatly should not attempt to install solar power yourself if you intend to power a residence with it (unless you live in a shack). A certified electrician is required in order to connect your equipment to your house's electrical system. It isnt just as simple as a few panels. You need a converter that turns the DC voltage generated into AC. You also need equipment to connect to the metering system for your house. If you want to see if it is cost effective, you will need your electric bills that show usage for a year and the price per kWH. There are a lot of websites that have calculators for solar power systems.
Q:How to connect solar panels to batteries?
You can use them without the regulator . Just make sure you use blocking diodes so the the power does not flow back into the panels . You can get those at radio shack of some electronic store or off OKorder for a few bucks .
