Q: i have to do a science fair project and thought it would be cool to make a solar powered vw bus. i have 2 6volt solar panels to power a dc motor that works off of 9v 2v or 8v. i also bought a 2nd motor because the first wasnt workin for us. this one is a 3v motor. ive had them in the sun but they wont work. please help, thanks: Ok okorder

Q: hi,i have 4 solar panels. I can get 9V 400mA when i wired them parallel. The question is: how can i make a regulator circuit to store power into batteries.: wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .

Q: i have this usb solar panel charger i am building and the solar panel is about 2by .5quot;, so i was wondering if a led light can power it, if so will one be good or would i need more? if so how many?: An LED requires an electric current to power it. A solar panel can most definitely power an LED, but LEDs don't store any power themselves. And solar panels aren't designed to be powered, they are designed to generate electricity. Rethink your premise from the start. It is as if you were asking if the electric wires in your home or community would be powered by the light bulbs and appliances you use.

Q: Can solar panels be installed on concert venues or music festivals?: Yes, solar panels can be installed on concert venues or music festivals. In fact, many venues and festivals are increasingly adopting solar power as a sustainable and renewable energy source. Solar panels can be installed on roofs, canopies, or even on the ground surrounding the venue, providing clean energy to power the event and reduce its carbon footprint.

Q: Can solar panels be installed on water bodies or reservoirs?: Yes, solar panels can be installed on water bodies or reservoirs. This type of installation is known as floating solar or floating photovoltaic (PV) systems. By installing solar panels on water bodies, it maximizes the use of space and offers numerous benefits such as reducing water evaporation, increasing energy production due to the cooling effect of the water, and providing an opportunity to repurpose underutilized water surfaces for renewable energy generation.

Q: Can solar panels be used for powering a concert venue or entertainment center?: Yes, solar panels can certainly be used to power a concert venue or entertainment center. By harnessing the energy of the sun and converting it into electricity, solar panels can provide a sustainable and renewable source of power to meet the energy demands of such large venues. With advancements in solar technology and the ability to store excess energy, solar panels can effectively contribute to reducing carbon emissions and promoting a greener environment for entertainment spaces.

Q: Can solar panels be installed on a government building or facility?: Yes, solar panels can be installed on a government building or facility. In fact, many governments around the world have been actively promoting the use of solar energy by installing solar panels on their own buildings. This helps them reduce their carbon footprint, save on energy costs, and set an example for others to follow in adopting renewable energy sources.

Q: How do solar panels affect my electricity bill?: Solar panels can significantly reduce your electricity bill by generating clean and renewable energy from the sun. By harnessing solar power, you can generate your own electricity, thus reducing reliance on the grid and lowering your monthly utility costs. In some cases, solar panels can even result in net metering, allowing you to receive credits or payments for surplus energy that you feed back into the grid.

Q: i'm making a small solar panel powered fan but it cant run the cellphone vibration motor even i have place two x2 solar panel.: A solar cell's purpose is to generate electricity through the release of electrons from a material that is bombarded by electromagnetic radiation or photons. Most crystalline solar cells are sensitive to visible radiation from 400 - 700 nanometers, which correspond to 3. - .8 electron volts, of the visible region as shown by ACEPT W3 Group (999) and also into the near infrared spectrum. As the wavelength of the electromagnetic radiation increases, the amount of electron volts decreases. This means that infrared radiation has less electron volts than the visible spectrum of light (because it has a larger wavelength than visible light) and ultraviolet and gamma radiation has more electron volts than both the visible spectrum of light and infrared radiation (because they have a smaller wavelength than both infrared and visible light). Abramowitz, M., Davidson, M., Neaves, S. (2003) wrote that all forms of electromagnetic radiation originate from the atom which contain orbiting electrons around its nucleus. When those electrons absorb more external energy than they can contain in order to be stable, the extra energy is released in the form of an electromagnetic wave. That electromagnetic wave contains a magnetic field and an electric field, one offset by ninety degrees to the other along the propagation plane.

Q: I wanna get a solar panel to charge or 2 car batteries. Then connect the battery to a 800watt power inverter so that I can power a tv. Will the 8watt solar panel charge my batteries and around in how long?I just wanna use the panel to charge the batteries, no to use the panel directly with my electronics. Thanks for your answer and help me with that.: welcome to the wonderfull world of solar! you probably have a 2Vdc 8 Watt solar panel, to figure out its charging amps capability we do this equation Watts/Volts=Amps 8watts/2Vdc=.5Amps this is a conservative figure, since solar panel ratings are calculated using winter time sunlight, sunny locations and more daytime hours will give you higher amps. a typical good condition car battery is rated at 40Ah (Amp hours).to find out the charge time, we use the following formula; Amp Hours/Amps=T where T is time in hours 40Ah/.5A=26hours this is charge for a single battery, two batteries will double to over 52 hours. lets compare to charging a battery with your car, a car alternator puts out about 60 amps but usually run about half capacity. 40Ah/30amps=.3Hours! An alternator is far more efficient so charging with a small solar panel is best as an alternative or for low power applications. As far as using an inverter to power a TV, we can calculate how long the battery will last by using the original formula. a typical 9tv will use 70 watts 70watts/2Vdc=5.8A 40Ah/5.8A=6.9hours this figure is by drawing all the power from the battery, voltage inverters have a safety feature that will not let you discharge your battery all the way, so 40Ah battery will power a 9 tv for about 4.5 to 5 hours.
