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:how to connect a solar panel to a motor?
A solar panel cannot operate a motor by itself. A typical system operates like this: The solar panel is connected to a charge controller which is connected to a battery which is connected to a motor controller which is connected to the motor. All these components must be compatible with each other. So,in other words, you can't run just any old motor with a solar panel.You can buy a system like an electric gate opener which is solar powered.
Q:How effective are solar panels now in N E with our 40+ snowfall this month?
Just As an aside the efficiency of the panels will also be maintained if the panels are cleaned of dust and debris. The maintenance of removing snow and dust is one argument for having the panels on a rack on the ground. Solar Thermal panels are intended to capture the sun's heat. Two types that make hot water are flat panels and vacuum tube collectors. The vacuum tube collectors work better in colder and cloudy areas but their efficiency prevents heat loss that might melt snow. Most of a light snow will fall between them but you are back to maintenance with a heavier snow. Flat panels are less efficient and will melt a light snow off of the panels for a heavier snow you will need the roof rake. The last type of solar panel are solar air panels. These are most often mounted on the side of a house rather than the roof as they are intended to provide hot air to the living spaces. They are essentially like little greenhouses. Unless the snow is building up against the side of the house these should be free from a snow problem.
Q:how much watts can a x2 inch solar panel make?
this type of solar panel has some few watts. Ah is a quantity (which represent energy) that define the flow of ampere for a period of hour. so, the max instant electric current is 40mA and the max power is 40mA x 3.6 = 0.44 watts but, this value depends of the solar ilumination which the panel is subjected.
Q:How much do solar panels usually cost?
Solar panels are currently selling for between $4 and $6 per watt of rated power output. A typical panel that you might install on your roof would be rated for between 00 and 300 watts and therefore will cost between about $400 and around $500 or so. A complete solar power system also needs some other components and will have some installation costs and so the total installed cost of a solar system is typically in the range of $8 - 0 per watt of rated power. Most home sized systems are rated in the 000 to 0,000 watt range and therefore cost between about $8000 and $00,000 dollars to install. Many states offer rebates and tax savings that can reduce this cost by as much as 50%. These systems will typically generate between about $300 and $2500 worth or electricity per year. Solar panels are expected to last between 30 and 50 years and so these systems will likely generate between $9000 and $20,000 worth of electricity over their life time in current dollars. This will vary widely though based on local electricity costs and may well increase greatly in the future if electricity rates rise.
Q:Why are solar panels grid-like?
These grids are required to absorb heat from sun and increasing the energy productivity :)
Q:what is the cost of getting km sq of solar panels?
As They are working on a reactor that makes diesel and electricity concurrently out of coal, biomass or possibly garbage in a non-polluting process.
Q:How can I power 5v or .08 amps in a remote loaction via solar panel.?
Search the web for some of the inexpensive solar Cell Phone Chargers. They can be hooked in series or parallel as needed to get you teh voltage and current needed. The 80mA is not too tough, thats not much current. Suggestion is to use a battery that is constantly trickle-charged by the solar panel. This will assure operation on a cloudy day or at night. Another strange source for solar panels and solar charge systems is, believe it or not, Harbor Freight Tools. they are on the web as well as have stores all over.
Q:Solar panel charging question?
Most solar panels have something called a charge controller on them. This prevents electricity from going backwards from the battery to the panel. Solar panels are rated at 2V but they do put out a little more than that during full sun operation. You didn't specify the size of your battery but it really doesn't matter. It comes down to your consumption of power. If you are only charging the RV battery so it maintains a charge when you don't use it very much, a 5 watt panel is fine. It will charge the battery and keep the small drains on the battery from making it go dead ( the clock radio, the theft deterrent system, etc use power even when RV is off) But if you are using the battery to run things when you are parked, you probably don't have a big enough panel. If you use a 30watt fluorescent light and a 00 watt laptop, you need 30 watts of power saved up every hour in your battery and that's with no inefficiencies. So if your panel puts out 5 watts an hour and you are using 30 watts an hour, you need 30 watts/ 5 watts = 9 hours minimum of charge time to run your stuff for just one hour. You probably need a panel of around a 00 watts to get any meaningful use of your battery. Plus, you never want to run your battery to full drain because it ruins the plates inside the battery. Watts = volts x amps. If you have 2 volts panels, you would charge at 8 amps with a 00 watt panel. This is a good charge rate. Any more than this and you risk warping the plates with too much heat.
Q:how many solar panels will i need?
you silly ! with Solar there is always room for error . you have to build it in to your numbers . solar is full of errors . So you should plan on producing at 3 times what you expect you will need . then you have enough .
Q:what is the best solar panels to buy?
You need an expert to tell you what the best solar panels are, in any case there is a gigantic outlay initially, each solar panel when I bought mine was around $ 600. I only had the two for my caravan, along with two heavy duty deep cycle batteries, they are able to discharge very low without damage to them, I have a small inverter which gives me 000 watts pure sine wave 240 volt. With my small set up I can use a micro wave oven and bread making machine as well as running power tools radio and television. Lighting can be efficient on ordinary 2 volt dc.They are far better than wind power I have tried that as a back up but I found it a waste of time and money most of the time. If you are connected to the mains power any power you don't use can be sold to the power supplier. With the really serious set up you can do anything with your power that you can do with the power suppliers. I set this of mine up to get away from the petrol generaters, I have had my panels for about 5 years and they are putting out the same wattage that they were when I bought them. I have not gone in for it seriously but I was told by someone that their mother had set up a system for $4,OOO and she received a grant of the same amount from the government and she sold her surplus power to the local power supplier. Incidentally I live in Western Australia.
