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 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:Should the value of solar panels be included when appraising a home?
Zillow appraisal is useless and not at all important. If you are selling your home then the solar installation should give you some advantage, depending on how much you are still paying for utilities. The only appraisal that matters is the one a buyer gets to lock in a mortgage. Nothing else matters.
Q:How long does it typically take for solar panels to pay for themselves?
The payback period for a solar PV installation is based upon the cost of the installation compared to the savings achieved. Therefore if you installed a modest set of panels yourself, did not need on site electrical storage and did not have any permitting fees but did enjoy rebates you would be doing better than if the installation costs were high, the solar equipment was expensive, you had to purchase storage batteries, it was costly to maintain and permitting was absurd. On the other side of the equation if your electrical use is high, you perhaps own an EV or you can sell power at a high rate then the costs you will be offsetting will be higher and the payback period will be lower. If your electrical use is minimal, there is no time of use metering available the payback period will be higher. Some of the costs you may be offsetting may not be electrical. If you concurrently purchased an EV then you may be offsetting the cost of gasoline which would be higher than electricity. Overall rebates and incentives play a major role. I have seen payback periods as low as 3 years claimed (commercial installation with special city tax breaks) and as long as over 20. A bell curve would probably find most of the installations in the 7 to 5 year category. A solar thermal installation (for hot water, heating and sometimes AC) is far more efficient and most would be in the range of 2 to 8 years.
Q:What is the anatomy of a solar panel?
You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
Q:how fast does a 25watt solar panel generate power to a battery?
To figure our how many you need, take a look at your power bill. It will tell you how many kilowatt/hours you used during the month. My bill says I use about 2000 kilowatt/hours per month, or about 2000 kwh /30 days=67 kw/h hours per day. That is 67,000 watt hours. To supply that with solar panels, you have to generate at least 67,000 watt hours, but you don't have a full day to do it, since you have to do it while the sun is up. So you put the energy into batteries during the day, so you can use it at night. A 25 watt panel generates about 25 watts when fully illuminated by the sun. If you fully illuminate it for an hour, you get 25 watt hours. If you get 2 hours of sunlight a day, that would seem to imply that I need 67000 watt hours/25 watts /2 hours=45 panels. But for most of the day, the sun isn't hitting the panel fully, so it isn't going to generate the full 25 watts. When the sun is 45 degrees to the side, you only get about 70%. When the sun is 60 deg to the side, you only get 50%. And what do you do on cloudy days? And the shorter days in the winter? To make up for this, you have to increase the number of panels to make up for the loss. So in reality, I might need double this number of panels, for realiable solar power throughout the year. That works out to about 90 panels, or ,250 watts worth for my house.
Q:Does infrared radition occur in solar panels?
- Radiation from the sun is mostly Ultra- Violet. - There are 2 types of solar panels, Solar thermal collectors and photovoltaic cells. - Put simply, photovoltaic cells take the UV rays and produce electricity. - Solar thermal collectors (which is probabl
Q:Why do solar panels stop working?
They really don't stop working unless there is some sort of manufacturers deficiency, where a connecting tab(wire) is broken. Generally their output just decreases over the years. There are plenty of solar panels over 40 years old still producing electricity, which is 0 years past the typical 30 year manufacturers waranty.
Q:i want to light up a building using solar panel what do i need?
The solar panels are made in China because there are fewer environmental regulations and cheap coal power. It takes a lot of energy to melt silicon and there are toxic waste products. It would be three to five times more expensive to make the panels in the US ( three times is just for reprocessing the toxic wastes ). Solar cell made in China are about $2 a watt, perhaps as low as $ a watt but in truth the claims for $ a watt or less solar panels as in thin film solar panels have much lower efficiency and require perhaps ten times more surface area.
Q:Solar Panels for home use?
For a starter you would look at how many watts you use. And how deep in you want to go. 80 watts at 2volts dc is nice.. But getting it to 20 ac. You will need a good inverter, battery's. There is things that you can replace in your house that will run on 2 volts. Lights fans. But to answer your question you would first have to look at what you use or and what you want to change over. I have got 900 watts of panels and 2700 Amp hours of battery's on one system. That will run all my lights computers and TVs Also on this I have converted a ups for the 20 VAC. I have been working on this for 0 plus years with no plans to finish. ( there is no end for what you can do with the power of the sun)
