Q:Solar Energy - What would these solar panels power?
note breath on the winds excellent answer is one quarter of one percent. See why houses aren't covered in solar panels? it's just not a real answer right now,. the rough rule of thumb is $0 per kWh ( for just the panels) you want to produce. You'd need $20,000 in panels and another 0,000 in controllers and inverters and batteries and who knows how much in installation.
Q:How to connect or use Solar Power Panels?
You will need help with this. Panels may or may not be 24 volt. If you can find a name tag, you can find out from the manufacturer's web site. Some folks hook them all in parallel. Mine are in series, to create 480 volts. the reason for going to higher voltage is to reduce power loss in the wiring. Even then, I used a wire size larger than recommended. The frames want to be interconnected, and wired to ground. The live conductors connect through disconnect switches to an inverter. The inverter is sized to the output of the panels. Where the utility allows net metering, the inverters are connected through a disconnect switch to the grid, which of course also feeds the house. Assuming you are on the grid, you will not need batteries. If outages severely impact you, you can have batteries. Counting against them is that they are costly, and use part of the power you generate, just to keep them charged. If you have batteries, it is usually best to rewire circuits so noncritical circuits are disconnected during outages. Leaving perhaps minimal lighting, fridge, freezer and critical medical circuits. Learn all you can from the Internet (try solar panels), and from the green search box above. Be sure to see if your state has a rebate program, and the conditions which it requires.

Q:Questions about the okorder.com solar panels?
Are there any extra unseen costs? (tools, energy converter, ect). Yes. Batteries or Inter-tie, charge controllers, inspections, wiring, inverter etc. 9. How much is it to get an electrician to hook you to the grid? Call for a quote. 0. Is it better to hook to batteries or the grid? Pros, cons, why? Batteries are expensive and only last several years. Maximum power is limited by the size of the inverter. Grid-tie eliminates the need for batteries but then you have to purchase a very expensive grid-tie inverter.
Q:how can i build my own, cheap, solar panels at home?
electric powered panels are actually not plausible for many persons. they are 2 great skinny layers of polarized cloth. while the solar hits them electrons pass from the st to the 2d layer with an quantity of stress. you are able to no longer reproduction that at abode. What you need to do is setup photograph voltaic heating panels and run them against a Stirling engine. this methodology is many times extra effective than time-honored electric powered panels besides in industry. they have warmth on one element and chilly on the different to generate stress. Hook that to any generator to offer electrical energy. in case you're useful construction a house gadget, weblog approximately it, others will desire to nicely known precisely the way you probably did it.
Q:Solar panels require big initial investment, how can I check if the money I save will be more than that?
Your school spend $0,000 per month or per year?? Photovoltaic (Solar Panel) panels have a really large initial capital investment. If you live in a location (e.g. West Coast Desert, SoCal) where there are many sunny days so you might be able to break even quicker. Also note ,there are state and federal grants that can help ease the capital cost. Energy demand keeps going up so expect our current rates to double. People who have alternative forms like wind and solar will have the advantage when this time comes. Just think of when the US had it's oil crisis in summer of 2008, people with small efficient vehicles such as Prius's didn't feel the price increase like the people who bought cheaper large SUV's.
Q:solar panels disconnected from battery?
Know that solar panels almost always incorporate a blocking diode to prevent a battery from back-feeding through an un-illuminated panel. Know that solar panels are usually connected to a battery via an electronic switching charge controller, not directly connected. Know that when a solar panel is open-circuited (disconnected from everything) it's terminal voltage will rise to almost twice it's nominal voltage. (22V is common for a 2V panel), unless it is stored in total darkness.
Q:Solar panel technology?
Well, you'll want to find the wattage your devices use. Then you'll want to be able to supply that with your solar cells. Plus a fair margin for emergencies. Most of them should have their expected wattage printed on them, but you could also get a meter to measure it. Beyond that, you will want an inverter, and some batteries.
Q:Solar panel connected to battery ??
Try to disassembled a solar powered calculator inside there will be all the materials u need to your project. U can safe all the trouble to trying to find the correct match. After using try to put it back in if not possible it is just a broken calculator, at least u still have a successful science project.
