- Q:what percentage of sunlight is converted into electrical energy in a solar panel?
- Depending on the type of solar panel, any where from 6% to 42.8%.
- Q:I want to put a solar panel(s) on my roof. What components do I need besides the solar panels? solar power controller? wires? How do I hook it into my home's electrical system and about how much electricity could I generate and save? Would the panels pay for themselves over time? Any help will be appreciated. Thank you!
- The first thing that you have to realize is that solar panels only make DC currant. This is used to charge batteries which when hooked to an inverter will make 20 v. AC. You need a large bank of batteries and a heavy duty inverter to power your house. There is also an automatic switch that will send power back to the utility company when you have excess power available. This is not a small project. Really think this out before you invest a lot of money for nothing.
- Q:Can solar panels be used to power a drone?
- Yes, solar panels can be used to power a drone. By harnessing the energy from the sun, solar panels can charge the drone's batteries and provide a sustainable source of power for extended flight times. This is especially beneficial for long-range or endurance missions where recharging options may be limited. Additionally, solar-powered drones offer environmental advantages by reducing carbon emissions and reliance on fossil fuels.
- Q:wondering if i should get them?? not sure if its worth leasing? also anyone know anything about solar city?
- They are absolutely worth it. I had a town house in Boston with solar panel shingles and they were able to supply enough energy for me to feed back the grid-- literally making money off of them. I am building a very large home in the suburbs now and we are doing solar shingles on that. Our contractor estimated that with our geotherm heat pump and energy efficient lighting we should still be able to throw back more energy to the grid all year round! As for leasing it is not worth it. For one thing, most leasing contracts prevent you from selling your energy to the grid yourself but rather they take a cut. But a bigger issue: the government gives you a tax credit on solar panel installations but only if you purchase them! I did the math myself the first time I did solar panels and with the tax credit I saved 25% over leasing. Something else to consider is that with your own panels you can connect a variety of other systems to your home and modify them as needed.
- Q:Solar panels do good more then bad?
- Like any other materials, solar panels need to be manufactured. These components are usually imported, they use energy to produce and transport. However, once you install solar panels, they need little or no maintenance (except cleaning to maintain efficiency) and they use no other resources to produce power. Over their lifespan, they'll produce more energy than was used to be made, so on the whole good for the environment.
- Q:The intensity of sunlight at the distance of the Earth's orbit is 380 W/m2. An Earth-orbiting satellite has a solar panel that measures .35 m by 4.86 m, which converts solar energy to electrical energy with an efficiency of 26%. In one hour, how much electrical energy does the panel produce? Assume that the satellite's attitude control jets keep the panel oriented perpendicular to the incoming sunlight.
- 380 W/m2. An Earth-orbiting satellite has a solar panel that measures .35 m by 4.86 m, which converts solar energy to electrical energy with an efficiency of 26%. In one hour, how much electrical energy does the panel produce? 380 W/m? x .35 m x 4.86 m x 0.26 = 2354 watts energy is watts*time E = 2354 watts x 3600 sec = 847472 Joules or, E = 2354 watt-hours
- Q:what is needed beside the panels and do you need an electrician to hook it up
- A decent installation needs a solar engineer to make sure the panels are aligned to take advantage of all the solar it can get. that or You need to hit the books on solar radiation. online I would try different programs to get the feel. we get less solar radiating in the winter then in the summer. this needs to correctly compensated.
- Q:There are places in the US where it is sunny almost all the time, like the southwest. But if we covered an area of the Sahara with solar panels, the sun exposure with the area would generate enough energy for the whole US at least. Plus, I would imagine it would be a great source of income for those countries.Why isn't this a topic under discussion or even mentioned between countries' governments/in Congress/in politicians' viewpoints?
- In the past, it was not economically feasible to mass produce solar panels. Because the costs associated with making them didn't outweigh the energy saved. But, there has been many recent technological breakthroughs with solar panel technology that makes mass production realistic. Just remember, even though we may have all of this great technology; in order for it to hit the public market, it has to make business sense. This pertains to big energy such as coal, gas, and oil; in the fact that current market sentiment favors green products. This means that since the market really likes green products and ideas, there is going to be a push towards greener sources of energy like solar panels.
- Q:I want to add solar panels to my home. I was looking online and it seems there are so many different kinds! How does it hook up to the electrical grid? How much do I need for a 2000 sf home?
- This is still not a trivial project, although it is getting easier. The usual way to do this is to contact professional installers for free quotes. In the process of getting the quote, you'll learn what considerations go into sizing a solar system. They'll look at your energy usage, and also whether your house has a good, clear, south-facing roof that doesn't get shaded during the day. They'll also look at your electrical panel to see whether they can hook right up, or additional work is needed. There are rumors of companies like Akeena planning to sell panel kits in Home Depot (in areas that Akeena does not directly serve). The idea would be that a pro installer would pick up the kit there, but a highly skilled homeowner might be able to make it work. A permit will probably be required by your jurisdiction, but that's no different than applying for any other construction. And you'll have to inform your power utility in advance, which may or may not be routine, depending on how often people connect solar in your area. If you want to see how we connected our system, a link is below. I did not really save money by doing it myself. That's because pro's can get better prices on the panels, which makes up for the labor cost.
