Production description

A solar panel is a collection of solar cells. Lots of small solar cells spread over a large area can work together to provide enough power to be useful. The more light that hits a cell, the more electricity it produces, so spacecraft are usually designed with solar panels that can always be pointed at the Sun even as the rest of the body of the spacecraft moves around, much as a tank turret can be aimed independently of where the tank is going.

A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricityin commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Q:Why are solar panels made from silicon and not magnesium?
One of the primary reasons solar cells are made of silicon is that the bandgap energy of silicon happens to be nearly equal to the energy of visible light, which is the major portion of energy emitted by the sun. Therefore, silicon is the ideal substance to fabricate solar cells with.
Q:solar panels on the house?
Q:How many solar panels do you need on your house to power your heater in winter?
You can get over 5 times the efficiency at lower cost by directly absorbing the heat in a solar water-heating collector. Use the electrical panels for making electricity for stuff that needs it.
Q:Best orientation for my solar panel?
It doesn't make sense to me. I am at latitude 37.7,and my panels face south at about 38 degrees. Yours should be pointed north as you suggest. Being so close to the equator, and in the absence of any better information, an angle of 2 degrees would be appropriate. However, choosing the best angle will greatly to your overall efficiency, so I would try to find a more credible source, How about the folks from whom you buy the panels. They would know precisely. By the way, if you haven't installed the system yet you might consider going to a high voltage system to cut known line losses in the conductors between the panes and the inverter, I did that plus increasing the conductor size over that recommended by the manufacturer. I gained about two percent in efficiency
Q:how efficient are flexible solar panels?
One I got about 3 years ago is about 50% as efficient as a glass panel I got about 0 years ago. Not exactly a scientific study, I know.
Q:How do you install solar panels?
Everyone is looking into renewable energy these days and many are looking to solar energy. The sun gives us a lot of energy that solar panels help us to use for our energy needs. Best of all, this energy is free! All you need to do is install your own solar panel. It is best to install solar panels to a rooftop before the house is roofed.
Q:where can i get a small solar panel to power an outdoor water pump?
Home Depot has several sizes for applications such as yours in the gardening section. Because I am always looking for ways to save money, even in the long run, I was looking at the possibility of solar power for here in SW FL.
Q:DIY home solar panels?
Not worth it unless you can get a fat subsidy. But Congress is working on a bill to provide a significant subsidy, and Oregon may have one as well. A solar plant costs about $0 per watt of installed capacity, and can produce a maximum of two kWh per watt per year -- which is worth about two bits. Without a subsidy, you are better off leaving your money in a savings account.
Q:When I make a solar panel what kind...?
You can make your own solar and wind power for less than $200. You can your power bill by making your own solar panels. You can save thousands of dollars and go green at the same time. 93.9% of the energy that is consumed by US is NOT from renewable sources. The best choices when it comes to home power are solar and wind power. These count for only 0.2% of the energy that is consumed. You can generate your own energy and send it on the power grids. If you don't use all the energy you produce the power company will pay you.
