Q: Solar panel experiment ?wat are some experiments with solar panels that has not yet been proven? ideas: Acciona of Spain is actively conducting research in all sorts of alternative energy. I understand they have an experimental solar farm someplace in the desert southwest of the U.S. that is made up of 283,000 panels. I don't know the size of the panels or anything else about the project other than that. 50 years ago it would have been the U.S. conducting leading research in solar energy-especially in the U.S. Southwest.

Q: My washer is 20 volts 60 gz,9.6 amps. The solar panels I am looking at are: Sharp ND-208U Solar Panels (208 Watt) List Price $,479.99 Only $,049.99 Sharp Solar Panels (208 Watt) List Price $,352.99 Only $,040.99 If I buy that will it be enough to run my washer?: Solar panels produce power in proportion to the amount of sun light and inverse proportion to the temperature. To use solar power you will need in addition to the panels a bank of batteries a charge controller and an inverter to convert to 20v. The panel(s) will only be used to recharge the batteries and the batteries connected to the inverter is what is going to run your washing machine. You therefore need to know how long is the machine going to run, how often and how much charging can you expect to get from each panel in order to figure out how many panels you will need and how many batteries. If you do only one load very infrequenly, you will be able to use a smaller battery bank and charge at a lower rate.

Q: Hi. I have been looking into getting solar panals but I only want them for one room. See, we're expanding the house by adding a basement, the basement isn't going to be that big but we wanted to have solar energy for the basement only. Could anyone give me a rough estimate on the cost of solar panals for my basement?: If you're really planning on solar energy, don't waste it on your own consumption. The Hydro company pays you for the energy you put back into the grid....the strange thing is, you buy the power back for less than you sold it, so you actually profit on the power you make! look into this. I wired a nice house for a doctor, and although I didnt supply the solar system, I learned of this concept there. The guy who installed her system charged her around $40,000.00 and the system would never be able to run any large portion of their home. They, of course sold the energy to the utility.

Q: Alright my family and i are buying a new home in Bradford,Ontario, we we thinking about solar panels and had a couple questions:. how much are they each?2. how many will we need to power a single family home(4 ppl)3. where can we find them in ontario?4.how much money do they really save you?5.what kind of energy do they providfe you withand other basic info or a website i can check out would be great!thanks in advance!: I have a system that was installed last year. I have 20 panels which provide me with about 75% of my electricity. I do use less electricity than the average home. I use an average of 45 kwh in the summer, my neighbor uses more than double that. I paid $26K for the system, but I got a $0K rebate from my utility and the US gives a fed. tax credit. I am saving about $2K per year, so it will take just over 6 years to break even. I also have what I think is called net metering, my utility allows my meter to run backwards when I generate more energy than I use, so pretty much the entire time the sun is out in the summer. Having energy efficient appliances, reducing standby energy and using conservative climate control really helps keep my usage down. Weather striping, insulation and clean well maintained systems all help as well.

Q: Can solar panels be installed on ground-mounted structures?: Yes, solar panels can be installed on ground-mounted structures. In fact, ground-mounted solar panel systems are a popular choice for residential, commercial, and utility-scale projects. They offer flexibility in terms of location, orientation, and scalability, making them an ideal option for areas with limited roof space or shading issues. Ground-mounted structures can be customized to optimize solar panel angles for maximum energy production and are easier to install and maintain compared to rooftop systems.

Q: How do solar panels affect insurance rates?: Solar panels can generally have a positive impact on insurance rates. While the installation of solar panels may slightly increase the dwelling coverage, the potential savings on electricity bills and the added value to the property can often outweigh any additional costs. Additionally, some insurance companies offer specialized policies and discounts for homes with solar panels, making it a favorable choice for homeowners.

Q: I need to write a pressuasive essay on why we should use solar panels more than we do. and convince people that their good and stuff.. if u guys could give me some good key reasons why..that would be great.: Right now, the U.S. government and some state governments (like California) are offering subsidies on solar panels for businesses and houses. With these subsidies, anyone infesting in solar power today will have their investment returned in less than 0 years. This means that with these subsidies, solar panels are basically paying for themselves; they're free. In addition, excess power generated on solar panels can be added to the local power grid and, if you're lucky and can set it up with your local power distributor, the power company will pay you for the power you generate. This are just financial reasons. Their is also the reduction of power generated by fossil fuels when using solar power which mitigates climate change.

Q: i'm making a small solar panel powered fan but it cant run the cellphone vibration motor even i have place two x2 solar panel.: this type of solar panel has some few watts. Ah is a quantity (which represent energy) that define the flow of ampere for a period of hour. so, the max instant electric current is 40mA and the max power is 40mA x 3.6 = 0.44 watts but, this value depends of the solar ilumination which the panel is subjected.

Q: how would you build a solar panel: i'd go to the solar panel store and buy one. It would be /0 the cost of trying to build one in my HOME shop.

Q: Hello,What do you all think about the future of solar panels and what role they will play in the near future. There is tons of money being dumped into the industry and demand is slowly rising. Also do you have any favorite solar links to get more info about them?: Solar Panel really isn't any new technology, it was discovered in the early 60s. And as you can see it hasn't progressed all that much. But Developers are saying that within the next five years solar technology will increase dramatically. With more and more people looking for greener and easier forms of energy, there are many looking towards solar. In fact some energy companies are willing to buy the energy that you produce from you. And with new forms of thinner silicon panels, we are looking at a more efficient kind of panels. Unfortunately for us, at the moment thin-film panel silicon isn't as efficient as we are looking for. They are flimsier than the traditional panels and do not contain as much silicon to produce the electricity. But as soon as the demand increases, the production will increase, and if more companies are looking to invest in solar, then there will be more competition, with more competition- we are going to have improved technology, and with more improved technology, the prices will go down. Because at the moment, there is not much of an incentive for solar power. Compared to the Kilowatt- hour produced from coal and other forms of energy, solar does not produce as much. Experts are saying that within the next five years, not having solar panels on your house will be as silly as building a house without plumbing. The future on solar panels looks bright.
