Q:Solar panels for a small gym outside my house?
Yes you can.. Use it to charge a 2 volt battery then use the battery power to run a 2 volt halogen bulb. Would be much better to power some LED's with the battery -- just as much light but will last longer.
Q:question about solar panels....?
Not many people realise it, but Einstein did not win the Nobel Prize for either Theory of Relativity. He was awarded the prize for his work on the photoelectric effect. i.e. the ability of some materials to take photons of light and turn their energy into electricity. Now, since most of the Sun's UV rays are filtered out by the Earth's atmosphere, else we'd be able to get a sunburn in seconds walking around outside in daylight, I think there is some energy imparted to the solar cells by UV wavelengths of light, but most solar cell materials rely on the wavelengths of electromagnetic radiation we call visible. Plus, I always thought infrared wavelengths conveyed more heat energy than UV rays.
Q:I have a 6v solar panel , but a 3v dc motor doesn't run with that!!!!?
It may be that the power output of your solar panel is not enough to drive the DC motor. It is producing up to 6 volts but it may not be producing many milliamps. LEDs need very little power to work but DC motors often need quite a high current to get them turning. If you can run several solar panels in parallel, you can probably increase the available current. Alternatively, can you expose the existing panel to much more light so as to get it to work at its maximum output? That might work. Good luck with your science exhibition.
Q:how can i optimize power in a solar panel?
first place the panel so it is at right angles to the solar rays. Make sure none of the panel has any shade whatsoever. For best results use motor drives to keep it in that position as the sun moves across the sky. For overall maximum versus time, you need to be near the equator. Solar cells have a high internal resistance, so for maximum power transfer, you need a load of that same resistance. A good charge controller will use DC-DC converters to provide that load. .
Q:solar panels for my home.?
Either you, or someone else, asked this same question yesterday, and the answers given were that it is not possible for us to answer it. The costs depend on where your home is located, what prevailing local labor rates are, how difficult it is to get the equipment to the site, etc, etc. I think one of the answers was that for a 3 bedroom, 2 bath house the cost for all the necessary equipment listed would be in the neighborhood of 20 to 30 THOUSAND DOLLARS. I think that was an underestimate, and that it could be 40 to 50 THOUSAND!!!!! The answerer also pointed out that due to the exorbitantly high costs of the technical equipment that at this time the equipment will wear out BEFORE IT EVER CAN PAY FOR ITSELF IN SAVINGS for on the grid electricity. I agree with that. You need to discuss your wants with 3 or 4, even 5 or 6 LOCAL ELECTRICAL CONTRACTORS to get a reasonably accurate estimate of the costs!!!!!!
Q:how much do solar panels cost and r thay worth buying?
If you want to get money from the power company you will have to basically put in $0k to $20k worth of solar panels. Currently most solar panels that are available to home owners are not all that efficient. I currently have 3 that are 2 foot x 0 foot on my roof that follow the sun and they only power my water heater. Also some states will give you a tax rebate for installing solar power banks on your roof, mainly in the southwest.
Q:Self build solar panel ?
Lithium okorder.com/ For USB power, there are some references you should seek out from the websites of Fairchild, On Semiconductor, Texas Instruments, National Semiconductor, just to name a few. There are others, and if your IPad has the control circuitry for the accurate charging of their batteries, and you just need the USB port to have the right power available, a high compliance regulator such as an LM7805 should do just fine. Spec sheets for that regulator are available through the above mentioned manufacturers websites as well.

Q:Questions about solar panels?
There are several web sites you can search for and they will provide the answer on how big of a PV Solar Array you would need for your house. Several things need to be known, such as square footage of the home, how well the home is insulated, etc. The panels come in all sizes and wattage's depending upon application, so yes they should all fit on the roof. If you have a small roof get PV panels with higher wattage's. Yes, they will work in the northern latitudes but not as efficiently as near the equator. You might need more PV panels to make up the loss in power from the sun hitting at a lower angle. Generally, all you will need to do is periodically clean the glass covering of the PV Panels to get maximum sun light on the PV cells. In my region, near the 45 th parallel, a 600 square foot home with six inch insulated walls and R40 attic insulation can purchase a PV panel system for around $40,000. That includes the equipment to tie it into the power grid and the meter to measure how much you supply the grid during the day and how much you draw from the grid at night when the sun isn't shining. There are tax credits for retrofitting an existing home, but mostly it is new homes being built that are having the PV panel systems installed so the cost is added to the mortgage and the return on the investment is paid off over the life of the System (about 5 to 20 yrs.)
