 20w Poly Solar Module With High Efficiency

Solar panel working process

In addition to being the ultimate source of all life on earth, the sun is an infinitely renewable, completely pollution-free source of electricity. Instead of burning fossil fuels dug up from the ground in a big power plant – a very 19th century, industrial age approach, when you think about it – solar panels convert sunlight directly into electricity, with no harmful emissions.

The basic unit of a solar panel is a solar cell, which usually consists of one or two layers of silicon-based semiconductor wafers. When struck by the photons in sunlight, the solar cell generates an electrical charge due to the "photovoltaic effect" – which is a pretty good name, since it produces voltage from photons. The flow of these electrons moves in a steady electrical current from one side of the cell to the other.

Dozens of these PV cells are packaged together into solar modules, which in turn are packaged into solar panels that are mounted on a rooftop and arranged to maximize their hours of exposure to direct sunlight. Because the electricity generated by all those solar cells is direct current (DC), it is then sent to an inverter that transforms the power into the same alternating current (AC) used by the appliances in your home and the local utility electricity distribution grid. Increasingly, these inverters are getting "smart," providing data monitoring for solar installation performance and other grid integration services.

Q:Run a air conditioner off solar panel?
Solar Panels Air Conditioner
Q:Does anyone know a good company to buy solar panels from?
a few months ago there was an article in pop sci about a company that has started to make solar panels at a fraction of the cost of what they used to be by using a printing style process instead of glass panel style they should hit the mass market soon that would be the best bet for a starting point to beat out price problems to allow a competitive edge they also had a article for low wind high power residential windmills for that could help in the alternative fuel push
Q:Wanting to add solar panels to my home?
image voltaic panels can set you back as much as $20,000. A windmill that produces sufficient electrical energy for the abode would be approximately $0,000. Neither gets you off the electrical powered grid. image voltaic in basic terms works while the sunlight shines. At night, you will have not have been given any electrical energy. Wind in basic terms works while the wind blows on the merely right velocity. decrease than 5 mph and you get no capability. If the wind blows too speedy on your windmill, it is going to close right down to maintain from being broken. look to insulation, capability valuable doors and abode windows, an capability valuable air conditioner, landscaping that aspects shade.
Q:What does it mean when a solar panel is 50 watts?

Q:how much money do solar panels cost?
In the US, the average electric cost $.5/kw-hr. $2500 means you are using 6700 Kw-hr/month or 550 kw-hr/day. Since solar panel only make peak kw for about 5 hours per day (in sunny places like (AZ) you will need a 0 kw system. Solar systems cost about $7/watt so your system will cost about $750,000. The government my pay for about $250,000, so be prepared to spend one half a million dollars. You will also spend about $250/month on maintenance of the system. The system will lose about %/year of it's efficiency, so the system will be paid for in 240 months, or 20 years. With in 5 years after the system is paid for, they will have to be replaced, the cost will be another 2 million dollars.
Q:Why are solar panels not that efficient?
I don't remember what number exactly but it's in the single digits. This number represents how efficient solar panels are at capturing the sun's rays and converting it into electricity
Q:Where can I get damaged solar panels?
Check out home power magazine for the list of vender's. Construction companies typically return damaged panels to the distributor or manufacturer for credit. The companies may have an inventory of goods for sale. Also, check out large insurance companies (Nationwide) to see what they do with panels they write off as catastrophic loss when a homeowner or business files a claim. Hope this helps
Q:What can a watt solar panel power?
You can run a lot of things. If you set the system to charge batteries when you are not using anything, they will charge effectively. You can use the system for lighting, LED lighting direct from the battery power is most effient since LEDs are low voltage devices with a very long life span. I replaced a 2 tube flourescent trough with four 5Watt PowerLEDs for example, While I have it on 20VAC at the moment, I can move it to 2 VDC power with ease, and had set it up to run initially on 2 volt sources. There are also many 2 volt appliances as well. You can even convert some of those all in one stereo systems to operate on 2 volts by eliminating the power supply. You will actually use less power by doing so. You will not be able to blow the shingles off the roof unless you add a Class D amplifier to the output, but for most listening, the output is adequate. Some small TV's these days can be run from 2 volt sources, if not directly, then with a buckboost inverter for a laptop. The small TVs only draw about 30 to 45 Watts. Skip the idea of using an inverter, they are not efficient at small loads, and represent additional load on the system. So with a little bit of planning, you can run a lot from that 60 Watt system. You can at least take some bite out of the electric bill for mundane lighting. You can also use them to keep power up on a battery system for lighting in a remote barn. The uses are only limited by your imagination and creativity.
Q:What is the principle of solar panels work?
The sun is irradiated on the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region. The electrons flow from the p region to the n region, and the current is formed after the circuit is turned on. This is the photoelectric effect of the working principle of solar cells.
Q:projector/solar panels help?
Do understand, that a solar panel is slow to pay for itself. Let's say your electric bill was $200 a month ($2400 a year). A solar system would cost perhaps $24,000 so you would actually have paid your first 0 years of electricity in advance when installing the panels. After that 0 years, you start to be ahead financially. It can still be a good idea, but it may not be the quick and cheap solution you were looking for.
