Q:What Are Solar Panels Made Of?
Silicon. They have to compete with computer chip makers for the same supply of silicon. As solar panels are becoming more common, the price of computer chips is going up.
Q:How much energy does it take to make, install, and eventually dispose of a solar panel?
Best way to determine that is to find the retail cost of a solar panel and compare it to the retail cost of oil. Assuming similar profit margins a $300 solar panel costs the same to produce as 00 gallons of oil.
Q:How many LED's can I hook up to my mini-solar panel?
You need to answer that by designing circuits to provide each LED with its specific voltage and current requirements, and then see how many you can supply.
Q:Powering my house with solar panels?
Homes vary tremendously in their usage. It will be a factor of 0: between a conservative house, and a heavy use one. To get the answer for your own house, check the electric bills. Also, the answer for the size of solar electric system varies with the location of the house. A Minnesota residence may get only 2/3 or /2 of what an ideal California house gets, even though both are sunny. As a data point, our California house has no air conditioning, no electric heat, no pool, and no big screen TV. We use maybe 5 - 8 kWh a day on average (more in winter, less in summer). We have a 3 kW solar array on the roof, and it roughly keeps up with our usage.
Q:Are our scientists making solar panels all wrong??
There are two basic types of solar panels. ) Thermal absorbers 2) Photovoltaics Thermal absorbers are black in order to convert sunlight to thermal (heat) energy. The whole idea is to capture all of the light with a dark surface, convert it to thermal energy and transfer the energy into your home for water heating or space heating. If you make the surface white or reflective, then the surface will absorb only a small fraction of the available light, hence the efficiency will be very low. In other words, the panel will not produce any heat. Photovoltaic panels produce electricity instead of heat energy. Photovoltaic panels are made from thin slices (“waffers”) of silicon with special coatings on the front and back surface. One of these coatings on the front is an antireflection coating to capture the light and channel it toward the silicon. Underneath the antireflection coating the silicon waffer is coated with other chemicals that convert the sunlight to electricity. The combination of these coatings gives the panel a dark color, usually blue or black. Here's the bottom line. If you want thermal heat or electricity from solar panels, the panels have to capture the light. When that light is captured, the surface appears dark because no light (or very little) light is reflected back to our eyes. It is not possible for a surface to be an efficient absorber, capturing all available light, and at the same time appear white or bright color or reflective to our eyes.
Q:Is there anyone trying to create a cheaper and more efficient solar panel?
The most cost-effective solution, which the vast majority of new installs use today, is solar alongside the regular power company. That way, you need no batteries, and if the solar array isn't producing enough at any given time, you draw from the electric company. When the array is producing more than you need, instead of just throwing that power away, the power company buys it (usually). In short, yes, you will still have an electric bill, but a smaller one. On our house, the electric bill was a little less than $5 a month, with an end-of-year settlement of an additional $2. How much does it cost? Unfortunately, that's like asking how much personal transportation costs. Some people need a van to transport the kids to soccer, some may get by with a motorcycle, others may need only a bicycle. The best thing is to contact a professional installer to get a quote based on your location and electrical usage. Solar electric does not make financial sense in all areas. Our array cost $2,000 but don't use that as a guide. Yours might be 0 times that, or half that, depending on your area and needs.
Q:Does anyone know a company that will make custom solar panels?
okorder.com Other sources available on the first Link also. Wingman
Q:When you get solar panels do you connect them to the grid?
You okorder.com/ as they provide very accurate free solar quotes and break down all the incentives you will be eligible to receive, your estimated annual savings, your payback period, projected IRR, and a cash flow analysis. They taught me everything I know about solar, and I must say they're a great starting point if you're curious about what solar energy is all about.
Q:Solar Panel - Cell Resources and Calculations?
The two wiki links below provide basic explanations that are good starters. They also lead to other information. You do not mention much about the actual project, so I can only guess what level to pitch the answer. In practical situations you will not be able to work out Solar panel performance by a formula, but by looking up the manufacturer's specification (data sheet). From that you have the power in watts that can be drawn from the panel for standard sun which is taken as 000W/m^2 at a standard temperature, usually 25C. Derate the panel for the temperature when it operates in the sun (50-60C).
Q:Question about commercial solar panels?
In my experience working with solar panels, I've found that the panels themselves are robust and can last years. How that energy is transferred from the panel to perform work (sorry for the boffinism) is where the complexity emerges, namely due to the fact solar panels produce DC current, and nearly all of our electrical appliances use AC current. In most cases, solar panels will either send energy through a DC/AC inverter directly to be used for appliances, or stored in deep cycle batteries, then converted to AC using an inverter when the user wants to use his/her appliance. Now to answer your question: the solar panels will be fine, and could conceivably be in fine working order with AC current available IF... and I cannot stress this enough (namely through years of field experience dealing with solar powered scientific instrumentation that was working well and then mysteriously not working)... IF rats and other rodents haven't eaten through the wires. This is probably the most likely reason that a set of solar panels wouldn't be working in your given scenario. Hope this helps, and good luck!!
