Characteristics of Polycrystalline 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. .

Q:How to connect 2 power supplies together? (Solar panels)?
Huh? you should have got something, in full sun, you should have gotten 3 or 4 volts, but milliamps in current. By connecting them pos. to pos., neg to neg,(paralell) it increases the current output. If you connect pos, on one, to neg. on the other, and measure between the remaining pos, and neg. you should have twice the voltage (series). You need 4 volts, but 4 AA's in series is 6 volts. If your going to use the panels to charge the batteries, you'll need a diode in series to prevent discharge during dark conditions, which the LED will work for.
Q:Questions about Solar Panels and Battery back ups.?
Q:Solar Panel Question?
There are 720 hours in a month (30 days) but only about /2 of those are in *full* sun 800 kW hr / 360 hr = 5 kW. 5000 W / 65 W / panel = 30 panels minimum and that's based on full sun during the day (no clouds, rain, etc). Besides an inverter you'll also want a bank of batteries to operate at night. OR, you can get about 35 - 40 panels and sell power back to the utility during the day (meter runs backwards), and use power off the grid at night. Suprise! solar power isn't cheap, is it? Figure on taking advantage of some government and public utility rebates, though to lessen the cost. .
Q:Why only Photo-Voltaic solar panels?
you completely nailed it!! speaking about large buildings, it would benefit one to do a little more research. my company just installed a 640 collecter system on a million sq foot building. it consists of a absorption chiller (which uses no coolant, just water a silica gel beds, runs of the power of its controller, thats it) 27,000 gallon tank. chiller feeds 2 rotation units and 2 large office spaces for heat and cool. payback expected at less than 5 years. we will expand this system another 200 collectors. residential installs, if tax credits used, achieve 5-7 year payback pending domestic hot water only or dhw and space heating. thermal collectors actually produce more energy than pv panels do, therefore more bang for your buck, also as i hope you all know, pv has around 25% eff, thermal has 95%. also to say the tech part is gone, we use flowmeters that calculate carbon offsets, energy saved, money saved etc...all located in a wireless monitor for the consumer to enjoy.
Q:How Can I Reduce A Solar Panels Output To 3volts From 9volts?
Solar panels generate DC power. Changing DC voltage is hard, which is why the power grid is AC voltage. AC voltage can easily be changed with a transformer. To keep the DC power (watts) the same at a lower voltage you need a DC to DC converter. That basically changes the power to AC with an inverter, changes the AC voltage to the new value, then rectifies it back to DC. It is probably hard to find a commercial unit that handles those voltages and then it will be expensive. But I have a simple solution in the special case of a solar panel. Solar panels are made up of smaller solar cells. The basic solar cell has a very low voltage, like half a volt. The panel has many of them connected in series to make a higher voltage. Just cover (shade) some of them and the voltage generated by the panel will be less. Of course that reduces the power. And you may need to experiment with shading different parts of the panel and measuring the result with volt meter.
Q:can I connect my pool pump to a solar panel?
What does the advertisement have to do with your question? Yes; BUT, depending on the pump, you may need several panels and possibly an inverter if it is an AC pump. You will ALSO need at least battery in the circuit to provide a load to the panel.
Q:solar panel inverters?
Stand Alone solar panel inverters function to change direct current (DC) from a battery to Alternating Current (AC). Stand alone inverters, which range from around 00 watts to as much as 8000 watts, are used to power a vast variety of personal or small business projects. Lower watt stand-alone inverters are often used to power laptop computers, whereas high-watt stand-alone inverters could be used to help power an entire household. In order to calculate what class of inverter you need for use with your solar panel, you will first have to determine the maximum sum of all of the Alternating Current loads in your project (or home). How to calculate the wattage you need from your stand-alone solar panel inverter
Q:Does infrared radition occur in solar panels?
Solar panels do heat up. But that's because the radiant energy from the Sun that lies within the infrared (IR) band of energy causes the material in the panels to heat up. And that's the same for any body that has the Sun shine on it. Your face, for example, will heat up while you get a nice tan on the beach. That's due to the heat producing IR radiant energy. Now if those solar panels are supposed to heat buildings etc., that heat produced in the panels when the IR strikes them will be transferred, usually by some fluid, to floors of the rooms to be heated. And as the amount of heat generated by the Sun is proportional to the area of the solar panels, bigger areas of panel will generate more heat than smaller areas. Photoelectric solar panels are another kind. Here the interest is in the visible band of radiant energy from the Sun. Heat, from IR, is still there, but it is not the product sought by PE solar panels. The visible light photons knock off loosely bound electrons from the photoelectric material (typically silicon based) and those electrons are siphoned off as current. That's where the electrical power comes from for buildings using PE solar panels to provide their own electricity.
Q:What if anything has been done to channel light power other than solar panels?
Crikey yes, all these terms should be googleable Solar chimney Solar cooker Passive solar Solar trough Solar water heating Double glazing I'm sure there are more, I thought clothes lines were powered by the wind?
Q:Why do glass covers improve the efficiency of solar panels?
the glass has an anti-reflective coating that helps the panel absorb more light (to convert to electricity) thant it would if the glass were not there. the other purpose of glass is to retain heat and strengthen the panel
