Q:How to connect 2 power supplies together? (Solar panels)?
Most solar lamps use a single .2V nicd or nimh battery as a back-up supply, so they should be able to generate at least .5V in full sun to allow charging of the battery (you can verify the voltage of a single panel with your DMM) If you have two of these panels, I wouldn't expect them to make more than approximately 3V. The proper connection would be a series connection where the negative of one panel connects to the positive of the other and the remaining positive and negative wires become the outputs. Try this connection and measure again with your multimeter set to DCV and the panels in full sun. If the voltage is not high enough, add a third panel wired with its positive lead to the remaining negative of the first two. This should bring your voltage up another 50 percent.When you wire the panels positive to positive, negative to negative as you already have, voltage will be that of one panel, but current output will double (more amps) If you have many of these panels, you could combine series and parallel wiring to increase voltage and current.
Q:How many Solar Panels do I need?
Everyday I use ,280 kWh 280 kW-hour / 24 hours = 470 kW WOW, that is a very high power level, most homes use an average of .2 kW. My guess is that you mean you use 280 kW-hour in a year, which comes to an average power of .3 kW, typical. Assuming you get, worse case, 6 hours of sun per day, for the first case, 470 kW, each solar panel generates the equivalent of 250 x6/24 = 60 watts, so you would need 470k/60 = 8000 panels For the second case, .3 kw or 300 watts, divided by 60 that is about 20 panels. Depending on where you live, you could need as much as twice that number. Plus you need charge controller, lots of expensive batteries, and an inverter. The big problem is periods of no sun. If you demand continuous power, and you have a period of, say, 24 hours with no sun because of storms, etc, then the number of batteries increases to the hundreds.

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:What minerals are used in making solar panels?
Not minerals. Elements. Silicon. Found everywhere. Group III elements for doping. Group V elements for doping.

Q:Wiring in solar panels?
You okorder.com/ If you are planing to build an off grid system or a grid tie system, it should be wired by an electrician. At the lest by someone that knows what they are doing. If it is a grid tie system you will need the local building inspector to sign the paper work before the public utility will allow you to hook in. To get the inspector to sign off you have to get a permit which requires a lic. electrician.
Q:how many solar panels and what type to power a laptop computer that has to be plugged in when in use?
There okorder.com/ Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q:Does a 50W solar panel generate 540kWh?
running six hours a day doesn't mean much. You need to look at the solar insulation charts for your school's geographical location to come up with a better factor. The easiest number for you to use is sun hours. For example, Washington DC averages 4.23 hours. Do a Yahoo search for sun hours and you should find lots of charts. Solar panels rated at 50W give this output at full sun near noon at full brightness (no clouds). The sun hour factor makes it easy to find the equivalent number of full brightness hours. So, using Washington DC as an example you have: 000 panels * 50W * 4.23 sunhours/day = 634kWh a day on average. You state your school uses 88240kWh/month which is 6274kWh a day. This would mean you need ten times more solar panels since there is no way to get more daylight. Be careful to put in all the units in your formula and cancel them out to make sure you don't end up with a nonsense result. The title of the question would be answered as followed: 50W/000 * 4.23 sunhours/day = 0.63kWh/day or 9kWh per month or 228kWh a year. These are annual averages. If you wanted a specific month, you would need the sun hours for that month. Hope this helps.
Q:where to face solar panels?
Not compass south, but solar south. It's easy to find. Google Find Solar south and you can get directions. Even better are trackers, that will let your panels track the sun all day.
