product description

 

The photovoltaic effect was experimentally demonstrated first by French physicist Edmond Becquerel. In 1839, at age 19, he built the world's first photovoltaic cell in his father's laboratory. Willoughby Smith first described the "Effect of Light on Selenium during the passage of an Electric Current" in a 20 February 1873 issue of Nature. In 1883 Charles Fritts built the first solid state photovoltaic cell by coating the semiconductor selenium with a thin layer of gold to form the junctions; the device was only around 1% efficient.

Following the 1973 oil crisis oil companies used their higher profits to start (or buy) solar firms, and were for decades the largest producers. Exxon, ARCO, Shell, Amoco (later purchased by BP) and Mobil all had major solar divisions during the 1970s and 1980s. Technology companies also participated, including General Electric, Motorola, IBM, Tyco and RCA.[16]

Q:I have a question about solar panels?
But at night where there is no sunlight does all the electricity shut down for the night? Electrical production shuts down, but most solar electric systems have some way of storing power. There are two main types of storage: . Grid tie. Basically this uses the power grid as a virtual battery. You produce extra power during sunlight hours to sell to the grid (other people use it) and you buy power from the grid when the sun doesn't shine. This is usually the most economical system, but whether you save money depends on a lot of things like: cost of installation, location, government subsidies how much you get for the electricity you sell buy. In other words, the details matter. Mostly location, which determines how much sunlight you get, electric rates, and subsidies. 2. Batteries. Usually a large bank of deep cycle lead acid batteries. Usually only used in off-grid systems and the cost of electricity is usually not competitive with grid electricity.
Q:Need isntructions for solar panel diy?
But be aware that building your own panels will cost more than simply buying ready-made ones. This was not always true, but it is today. As you can see, this kind of information is widely available for free. Beware of scam sites that have a slick pitch making unrealistic promises, trying to sell you an e-book or video of the same stuff.
Q:Solar Energy Panels, a good idea?
Yes, but it is still very expensive at the moment. Look into solar leasing where you rent your roof to a company that installs and owns the panels and pays you a portion for surplus energy beyond your usage. I looked into going off the grid a couple years ago and based on our usual consumption it was going to take a $40,000 investment with a 0 year payback for panels, inverter, and storage batteries.
Q:How much do solar energy panels cost?
The okorder.com and read the to build or not to build article. Hope this helps. Dan
Q:How tangible do horseshoe solar panels sound?
Well here would be the problem with a horseshoe panel... Due to its shape, you will get a seriously uneven distribution of solar charge. Since the horseshoe shape resembles a parabolic function, the majority of the electrical photovoltaic cells will be spanned over the larger rise/run, meaning the two ends of the parabolic shoe. A way to combat this is that as it approaches 0 from both sides (0 tangency) is to put a higher concentration of photovoltaic cells in comparison to the two ends on either side. An even better design I would say would not to use a flat panel or even a horseshoe, but instead, use a sphere shape. It's globe-like shape would never need to be adjusted. The side pointing towards the sun would absorb and the remaining 360 degrees of shape would absorb ambient light which can trickle in tons of ambient charge. It is an eyesore but the round shape would be the most efficient. If you think about it, nature is the best example to model. Just look at a tree. It's general tree shape is rounded so that all the leaves can pick up some sort of light throughout the day.
Q:What size and watt solar panel?
I think that typical solar panels are 2'x4' and produce something like 800-000 wh per day. (That's 0.8 - kwh per day.) More in the summer, less in the winter, if they're aimed sort of at the sun. There are newer, more expensive panels that produce more. There are also thin film panels that are less expensive, and probably more sturdy. You then have a couple choices. In a house, you'd have an expensive inverter to connect to the utility power, so you can have power at night when your panels aren't generating anything. In a trailer, you want 2-4-6 deep cycle car batteries to store the power. Then you could have an inverter to convert that power to 20v AC, so you could use normal appliances. Or, you could buy appliances that run on 2 volts DC. Maybe a combination of both. You'll need to figure out how much power you're going to use, so you know how many panels and batteries you're going to need. The calculation is easy. Figuring out how much power you need is hard. You need deep cycle batteries because you can repeatedly charge them way up and run them way down. Ordinary batteries die fairly quickly when you do that.
Q:How many and what size solar panels would I need?

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.
