Q:Mitsubishi Solar Panels For Home Installation: How Much Do The Panels Cost?
Panels will cost in the range of 300-600 dollars for about 00 watts on average ( enough for one large lightbulb to run a few hours a day). The rest of the system needed will cost $2500-$4000. That is for the equipment. Cost for Installation?? Figure about 0 year life on equipment. It will probably never pay back investment, but will cut power usage. You can reduce power usage much more cost effectively buy simply conserving (Hot water temp. down, CFE bulbs, Better insulation, Better windows, Heat/Air a little colder/hotter, Attic ventilation, Geo Thermal heating/colling system). All of these measures will pay back sooner and save power usage. Solar will never pay back without major subsidies from the taxpayers. Particularly if in an area that has many cloudy days. Check it out. The calculations are basic and the facts are available if you really want them. Don't believe any salesmen or Environmentalists. They don't want you to know the facts.
Q:260 watt solar panels on an rv?
It depends on the power you need. There should be a controller between the battery and the solar pv panels.
Q:Cost and energy generated by solar panel?
A little more than 0 watts per square foot, so that size panel would generate 250 watts under ideal conditions, which is noon on a sunny but not too hot day, near the equator. That's about /3 horsepower, or the same power as a man working hard. That is larger than needed to keep the battery of the car charged, unless you plan to run a laptop or something off it at night. The power is also too small to power the car for driving. If it's an electric car, you could get maybe another 2 miles per day out of the car, again, under ideal conditions. An RV store might have an idea of how much installation would cost. They would be accustomed to solar panels for RV's, but probably not small cars. A panel of that size would cost perhaps $500-800 just for the panel.
Q:What are your opinions on solar energy?
It is definitely worth doing your homework to evaluate how much you electricity you want to obtain, what you location will allow, and the availability of state and federal tax credits. I suggest reading about it in a book or e-book. Check out the referenced source on solar calculator for cost and size detailed information, it's fun and informative.
Q:How I can get 300- 500 Wh of energy using Solar Panel?
A short answer is: 500 watt hours can be obtained with a 3 foot by 3 foot photovoltac panel in any 24 hour period with average conditions. Some 24 hour periods will fall far short of 300 watt hours even with the 5*8 foot panel, but a battery that stores several thousand watt hours, will likely give you 300 amp hours 362 days per year, with the 5*8 panel except very unfavorable locations such as Nome, Alaska, USA in December, and January. Nome is quite favorable Spring and Summer if you rotate your panel to keep it facing the sun up to 24 hours per day. Neil
Q:Where can i buy mini (v - 2v) solar panels?
Jameco okorder.com/
Q:Photodiode vs solar panels?
yes. Any semiconductor junction will convert light into electrical energy, just shine a light at an LED (connect LED to voltmeter) and you'll see a small voltage produced (if you configure the meter as an ammeter it will develop a very small current). Solar panels are just VERY large surface photodiodes.
Q:Solar Panel, what is the catch ?
using solar panel in your life, you can save the electricity bill, also you are saving energy for our later generations. If more and more people are using solar energy, the mother earth will become more beautiful.
Q:solar panels, help?
This is pretty much an exercise in knowing units and dimensional analysis. Watts are in Joules/second. So every second a square with the area(meters^2) of meter^2 receives 380 joules from the sun. In your case the square is the solar panel. So find the area of the solar panel in m^2. If you multiply area times intensity you can see that the meters cancel out and you are left with Watts(J/s). Since you want the Joules received in an hour you again multiply by how many seconds are in an hour. Leaving you with joules. What you have now is the total energy, but your solar panel is only 26% efficient, so just multiply by .26 and you will have your energy.
Q:solar panel model HELP!!!!!!!?
There are different types of solar panels. Photovoltaic for electricity, and thermal for heating water, and passive for heating air. So it would help if you would say what type you are going to build. Theere are a lot of videos on you tube on how to make solar panels. use the link below.
