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:What is the difference between solar panels and light panels?
Crystalline silicon cell conversion rate, rich in raw materials, is a large-scale commercial production of the battery, but the crystal silicon battery brings the harm can not be ignored. Crystal silicon series of batteries have a "three high more than a" common problem. High cost, high energy consumption, high pollution, byproducts and other shortcomings.
Q:How to charge a Battery with Home Electricity and Solar Panel together?
connect the solar panel to the Battery direct during the day time that's how it works in ALL situations !
Q:How much energy does this particular solar panel produce?
It's virtually impossible to estimate how many panels would be required, without knowing your electrical usage, and where the house is located. I'll give our house as an example, but it could be off by a factor of 0 (not kidding) from yours. We have gas heat, no air conditioning, and no pool. We live in a dry, sunny area of California, and our roof is ideally oriented for panels. We would need 25 such panels, but we are grid-tied. If we wanted to disconnect completely from the electric company, we would need 20% more panels to compensate for battery inefficiencies. So, the estimate is 30 panels. Here are some caveats: ) Air conditioning, especially central air, could double or triple the estimate. 2) An area that gets less sun per year (northern US, for example) would need more panels. 3) Typically, when a house has grid electricity, they keep grid electricity when they get solar panels. It's much cheaper to use both in tandem. 4) That's a horrible price for the panel in the picture. You can find a 200-watt panel for less than that. 5) Other equipment is required besides the panels to run your house off solar. You can read up on it on the internet, or ask a professional solar installer for a free quote.
Q:Nuclear reactors vs. Solar panels?
You should research nuclear reactors and their emissions. Mostly it's waste heat, and if they use a water-based cooling reactor, there can be significant emissions of water vapor. Some might consider the spent fuel an emission too. Waste nuclear material disposal is a problem. Research it. Solar panels have no emissions during operation, but there is some nasty stuff emitted when they are manufactured. 2: Maintenance of solar panels is pretty straightforward: keep them clean, trim overhanging trees, shrubs, etc., check for and clean corrosion, contaminants, etc. regularly. Maintenance of nuclear power plants, so far, is a full time job for many technicians and engineers. The recently developed portable (the size of a shed) nuclear generators claim zero maintenance for 20+ years. That's a big improvement.

Q:Can a solar panel work with an inverter?
There could be a couple of reasons why it isn't working. First, 2V panels actually put out a considerably higher voltage because it is presumed that they will be used to charge a 2Vdc battery. That requires applying a voltage greater than 2Vdc, and usually there is a solar controller that regulates the solar power to the battery. It also has a voltage drop. Look at the first reference reference, and you will see these values for a particular panel: Voc: 2.6V (open circuit voltage) Vmp: 7.2V (voltage at maximum power point) Voc is the voltage the panel produces under standard sunlight and temperature conditions (25°C), with no load applied. As load is applied, the voltage drops (see reference 2). Power is the product of current times voltage, so at one set of conditions (namely at Vmp) maximum power is available from the panel. Your inverter might not be working for either of two reasons: ) it has input protection circuitry that locks out operation when it senses an overvoltage, as in the 2.6V open circuit voltage, or 2) the panel does not produce enough current and the voltage from the panel collapses under excessive load. For example, if you load your inverter to 20W, then nominally the 2VDC input to the inverter must supply 20W/2V/eff = 0A/eff Assuming the inverter has an efficiency of 80%, the input current required is: 0A/.8 = 2.5A A solar panel operating at maximum power would need a rating of about: 2.5A x 7.2V = 25W Is your panel that big? The other option, as mentioned by others, is to charge a battery that runs the inverter. Other nuances: Voc increases as temperature decreases. Sunlight intensity varies (obviously), so the panel may produce less than rated power. The power specifications often are printed on the back side of the panel.
Q:Why are solar panels placed on the roof of houses?
Solar panels are placed on the roof because many times the roof has good exposure to the sun providing the roof is not blocked by trees or something else so that sufficient sunlight wouldn't be absorbed. Also the panels would more likely not get damaged on the roof opposed to being in the yard. If they were mounted on the windows, how could you see? And, the windows could easily break and then what would happen to the panels? Placing the solar panels on the floor would not be practical. A lot of sunlight is needed for the cells to produce electricity and how much goes on the floor? Most roofs are at an angle which could perhaps improve the amount of sunlight the panels would get, and roofs provide a lot of unused space. The roof is the best place. Furthermore, roof solar panels are available now to blend in better with the roof so that they are more pleasing to the eye. Even if you have a small roof, some panels could be placed there provided the roof is not blocked so that the sunlight it gets would be sufficient (about 4 or 5 hours of sunlight a day is needed). And, if you needed addition panels, they could be mounted in your yard as long as the mount was close to your power box and received sufficient sunlight. I applaud your desire to use solar panels. You could possibly save 50 - 90% on your electric bill and help your environment at the same time! A Win - Win situation!!
Q:how to make your own solar panels ?
On my website you can read my story of how my dad made solar panels at home for a little over $200, and now he pays nothing to the electric company.
Q:Im looking at getting solar panels.
Most major cities have construction signs and other public things powered by solar panels. We have parking meter stands, USGS meters, street lights, etc. when these lose efficiency, they need to be replaced. They still work at about 60 percent efficiency. Learn who services these items and ask how to get them at a reduced rate or even for free. Be personable and nice and go to the source physically, not via e-mail. You can get a solar panel to run just about anything
Q:solar panel model HELP!!!!!!!?
There are different types of solar panels. Photovoltaic for electricity, and thermal for heating water, and passive for heating air. So it would help if you would say what type you are going to build. Theere are a lot of videos on you tube on how to make solar panels. use the link below.
