Product description

A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.[2] It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.

Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.

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 electricity in 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:How many and what size solar panels would I need?
Solar okorder.com in their survival discussion in the archive, this exact project was discussed at length.
Q:The effect of colored light on a solar panel?
It is based on what the solar panel is made out of. Many of them will generate electric into the NIR region.
Q:Are you a solar panel specialist?
No, just an amateur. I guess that could be called an Enthusiast. I think most people find the topic somewhat interesting, some more than others. Why do you ask?
Q:how much does solar panels cost for you home?
I just got a quote for my place. It came out $8/Watt installed. The quote was for 24 - 20W panels. Dividing the total quoted price by the 24 panels comes out to $,750 per panel. This includes the complete system with the converter and cutoff switch to connect it to the grid. This is also a top-of-the-line system. There are cheaper systems with shorter life spans. My quote was for a system with a 30 year life expectancy. There is a Federal tax credit in 2009 of 30% that will bring the system cost down. There are also nice state tax incentives in CA.

Q:Are solar panels a viable option in IL?
Absolutely you can have solar panels in IL, there Anna. I am from Rochester, NY so I am a little familiar with frequent snowfalls! Plus my In Laws have solar panels and they live just outside of Chicago. (Oak Park sounds familiar, but I cant for the life of me remember the name of their community) Check with your local building department as to what you may have to do to your existing roof, as the panels and its necessary roof bracing can be quite heavy. Add a good Lake Michigan snowfall to an already heavy roof and you could have yourself a big problem! In better news many utilities and states around the country provide financial subsidies and incentives that along with the subsidies from those from the Federal Government greatly reduce the initial cost and speed up the amount of time it takes for you to recoup your initial investment. Solar panels by their very nature are warm, as they absorb the light from the sun. The latitude for IL is such that the solar panels on your roof will be tilted so much that the only way snow can build up is if there such a snowfall on your roof that its accumulation rises above the solar panels. There is no such thing as heated solar panels and you can very easily have solar panels in climates ranging from the Carribean to Northern Canada/Alaska. If you get serious about solar energy give a company called Sun Electronics a call. I know it may sound lame but my in-laws used them for their house and have been quite happy with the outcome. My In laws (at times) are cheap and are not an easy crowd to please.....but again are very happy with their outcome! Good Luck.
Q:Solar panel angle question..?
You did not give the details of how the legs are attached to the panel. I did some calculations on my right triangle analysis application. Based on an assumption that the legs are vertical and attached to the bottom of the panel top, i calculated the legs must be 6.97 inches long. This compares favorably with the 8 inches you quoted. t If my assumption is true, the leg length for a 7 degree angle is 2.925 inches. The configuration, if my assumption is correct, will be a right triangle. The hypotenuse (longest leg of the triangle) is the panel length and the vertical legs are the supports. If my assumption is incorrect, edit your question to detail the support /panel configuration. TexMav
Q:Questions about charging batteries via solar panel...?
Yes, you have it right you need two 2V panels wired in series to give 24V to charge a 24 volt system. But along with the 24V you also want some amperage, otherwise it takes forever to charge. Most of the little chargers are called trickle charges because they only have an amp or two. If you had two 25 watt solar panels putting out 24V you have : watts = volts * amps 50 watt = 24V * x amps x = 2 amps If your battery is say 50 amp hours of storage, then if you are putting in 2 amps it will take you 25 hours of sunlight to power it back up from a dead battery. So the charge time depends on how many amps you are putting in there at 24V A car battery charger typically charges at 0 amps at 2V, so 2 * 0 = 20 watts of power going in there So if you go solar make sure to use a charge controller and a big enough panel to get close to 00 watts for any decent recharge time. The charge controller makes sure that the battery only gets voltage going one way and it least 24V. So if the sun went behind some clouds and the voltage dropped to 20V, the controller shuts off the current until the voltage equals 24V or more
Q:Are solar panels actually efficient?
Solar panels currently hook into the electric grid through a rectifier. If you were not into the grid, you would have a battery bank to use at night time. Wind works the same way, rectifier, and battery bank if you are not connected. There are communities in Europe that are wholly powered by solar now. There are computers that direct the panels into the direct sunlight for maximum efficiency. Look for them to be coming to your neighborhood soon.
Q:How does a solar panel work?
The term solar panel is best applied to a flat solar thermal collector, such as a solar hot water or air panel used to heat water, air, or otherwise collect solar thermal energy. But 'solar panel' may also refer to a photovoltaic module which is an assembly of solar cells used to generate electricity. In all cases, the panels are typically flat, and are available in various heights and widths.
