Q:when we say a solar panel has 20% efficiency, do we mean that it converts 20% of sunlight reaching it into electricity or that it converts 20% of visible light(which is only 7% of sunlight) into electricity?: Sunlight power panels had been the go-to choice for many years. They are among the many oldest, most efficient and most liable methods to produce electrical energy from the solar. Every module is made out of a single silicon crystal, and is more efficient, although more pricey, than the more moderen and less expensive polycrystalline and thin-film PV panel technologies. You can normally appreciate them through their color which is more often than not black or iridescent blue. The silicon crystals have lengthy existence and they may be able to withstand wear and tear with out degrading its workability. Additionally solar is a main source renewable vigour as far as the sunlight method is worried. Sunlight has little influence within the residing creature. So sun panel should be in practice

Q:Are the solar panels on the roof just a gimik to get all the tree huggers to buy it, or are they actually a good, efficent design?: treehuggers already want priuses. the solar panel is meant to run an electric ac system that cool's the prius if the car gets too hot inside. its nice, but personaly, i'd rather have it charge the battery.

Q:Didnt solar panels use to cost around $250,000 5 years ago?: I okorder to register for free and lock in long term costs. The increasing demand and competition is helping reduce costs.

Q:If my school uses 88240kWh of electricity per month and I have 000 50W solar panels running for 6 hours a day, does it mean it will take 88240kWh / {{[(50W x 3600s)*000]/000}kWh x 6} number of hours to generate that much electricity (88240kWh)?: your first question: Does a 50W solar panel generate 540kWh? 540 kW-hr / 50W = 3600 hours it would take that long for the panel to generate that amount of energy. your second question is confused, as you both stipulate the number of hours at 6 hours per day, and you try to solve for the number of hours. 000 x 50w = 50 kW 50 kW x 6 hr/day x 30 day/mo = 27000 kW-hr/mo = 27 MW-hr/mo that is the amount of energy generated. That is nowhere close to 88240 kWh or 88 MW-hr. I would take 7 times more solar panels to generate that much energy. .

Q:Since plants have been populating this earth for the past 475 million years I think they have evolved to gain the most sun with their greenery. If scientists used heat sensors to find the hot spots of trees and trim all of the leaves that don't quot;providefor the plant, then maybe that trimmed tree could be used to become a solar quot;panelquot;. I believe that each individual leaf could be replaced by a small solar panel and the wood of the tree would be wiring that would root all of the solar panels to a generator.: I don't know much about solar power. This does however seem to be a very interesting idea. But I'd imagine that the complexity of building such a structure would be far more difficult that just laying thousands of large panels in an area. The shadow from higher panels may also have an adverse affect on the lower panels. Consider the tiny panels that do provide energy and compare them to a large panel that is easier to make.

Q:Single crystal solar panels and polycrystalline solar panels: Monocrystalline silicon cells in the laboratory to achieve the conversion efficiency of 24.7%. Ordinary commercial conversion efficiency of 10% -18%. Monocrystalline silicon solar cells because of the production process problems, generally its semi-silicon ingots for the cylindrical into, and then through the slice -> cleaning -> diffusion knot -> remove the dice -> the production of electrodes -> corrosion around -> Reflective film and other workers made of finished products. General monocrystalline silicon solar cells four corners for the fillet. Monocrystalline silicon solar cell thickness is generally 200uM-350uM thick, and now the production trend is to ultra-thin and efficient direction

Q:Can solar panels be installed in a community or neighborhood?: Yes, solar panels can be installed in a community or neighborhood. In fact, many communities and neighborhoods have embraced solar energy and installed solar panels on residential and commercial buildings. Installing solar panels in a community or neighborhood can contribute to a cleaner environment, reduce energy costs, and promote sustainable living. Additionally, community solar initiatives allow multiple households to collectively benefit from shared solar installations, making it accessible to a wider range of residents.

Q:i am doing this group project fro school. I would like to know if anybody knows anything about how to read a Spec. Sheet on Solar panels and where I could go to start researching them. Anything would be great!: Rate ,power , voltage and effencicney are four important iterms to choose one battery.

Q:I have made a 5v dc 52watt solar panel and I going to be trying to charger 4 2v dc 55ah batteries. I get about 6 hours of sun on my panel. Spec below, is that a big enough panel to charge the batteries???I have 30 3x6 solar cells wired together Cell Specifications: (Watts): .75 Wp (Amps): 3.5 Imax (Volts): 0.5 V max which is where I got my 5g 52watt max (if math is wrong plz tell me) The Battery type: 2Volt 55.0ah NB Sealed Lead Acid Battery. I am using a mppt solar charger.: Technically, any solar panel can charge any battery, but it would take quite a long time do do so if it is a large battery. If you are aware of the voltage and either amp or watt rating of the unit that is usually used to charge the battery, the solar panel should have a similar power output to that charger to work well. amps and watts are quite similar, and can be converted with this simple formula: W=watts; V=volts; A=amps; W/V=A; V*A=W; When charging batteries, it is always wise to use less amps than needed, and roughly the same voltage as the battery being charged. The less amps used to charge batteries means the battery will take longer to charge but will last a lot longer in the long-term. Your solar panel should be sufficient to charge the battery, but you should test charge it to see if it works well. I recommend using a multimeter to check the batteries voltage every couple of hours. Once the battery reaches 2v, it should be fully charged. You should also check the amps in case they are not at the expected value (take caution when checking amps with a multimeter, when i do it i always end up melting my multimeter leads). The battery should be fully charged from anywhere between 6-48 hours. if it is charging faster, the solar panel has too much power. if it doesn't charge in this time frame, the solar panel is not powerful enough.

Q:I am curious about how much of the energy that a solar panel of a given size and capacity will produce in it's lifetime, and what fraction of that energy was required to produce it in the first place?: The attached link is to an article from the 200 Home Power magazine. In that article the energy payback was found to be between 2 and 4 years. Newer panels are more efficient primarily because the silicon wafers used today are thinner. The silicon cell embodies most of the energy required to make a solar panel. Today most solar panels will produce the amount of energy required to manufacture them in between about 9 months and 2 years depending upon the specific technology used to make it. Solar panels are expected to produce energy for between 30 and 50 years. Therefore it takes around 5% of their total energy production to produce them. Note that these figures depend upon where the panels are installed. Panels in very sunny areas may generate more than 3 times the energy of panels in a cloudier area. Edit - The energy payback meta-study that carbonates references below mention one particular study Alsema (2000), which the authors used as a baseline to come up with their 4 year payback figure. These studies DO NOT assume ideal conditions. The Alsema study assumes an annual an irradiation of 700 kWh/m2/yr. That is the United States average irradiation and does take into account cloudy weather and the like. Under idea conditions the amount of energy collected can be almost twice as much. Albuquerque New Mexico is an example. The figures I mentioned above are recent values reported by several different panel manufacturers with whom I discussed the issue at the 2006 IEEE 4th World Conference on Photovoltaic Energy Conversion held this May. The very long payback times that carbonate highlights are almost certainly wrong. The study he references concludes that paybacks range between 2 and 8 years with 4 years being the most likely. In my opinion payback times are actually a fair bit shorter based on conversations with the manufacturers.
