Q:How many solar panels do you need to power a house?

Q:Linking multiple solar panels?
It will not hurt the panels to hook multiple ones in parallel (all red or positive wires together, and all black or negative wires together), and connect it to the single port on your charge controller. The more alike the two panels are, the better this will work. With two absolutely identical panels, you should get twice the power. With mismatched panels, somewhat less. This arrangement will not hurt the charge controller, either. The worst that happens is that the controller isn't able to take full advantage of all the power available. By the way, it's not advisable to connect both solar and wind together.
Q:What would happen if a car ran over a solar panel?
Cars and SUVs weigh anywhere from a couple of thousand pounds up to ten thousand pounds. Solar panels are typically not designed to take that sort of weight. So the short answer is that it would crush the solar panel, and certainly damage the photoelectric cells inside it. - Stuart
Q:powering an imaginary city! (need solar panels!)?
Depends upon the technology, but keep in mind that biggest may produce the most output per panel but smaller panels may have a higher efficiency factor and so produce more per sq meter.

Q:How much is the average solar panel?
You are way out of your depth if your report for science class is supposed to be knowledgable. First of all, Solar panels alone will NOT be enough to charge the battery bank, which you don't even mention in your quesiton. Secondly, the only way to have a usable 2 VDC system is to use a wind generator to keep the batteries charged to capacity and, as a plus, they will work at night. A 65 Watt ARCO Solar Panel is about $300 and you need to figure your power by the Wattage Rading for the particular panels . You also need to add in the cost of a 2VDC to 0VAC invertor, monitoring panels etc.... AND... just how big is the ROOF of the house you are planning to use.? This is an area of involved study and it's a bit more than what you are imagining for your high school science class report.
Q:How to maintain a battery with a solar panel?
What I would suggest is that you find a panel that is rated for 00 mA, at any voltage higher than 8 volts. A 2 or even 8-volt panel will do, because the voltage will drop to match the battery. Then I would get a diode to put in series with the panel to prevent the battery from discharging through the panel at night. That's called a blocking diode. At such low currents, a charge controller is not worth it. There is not enough power to overheat the battery, which is principally what a charge controller protects against in a larger system. Be aware that you could also simply plug a trickle charger for the battery into the wall outlet, at a cost of less than a penny a day in electricity.
Q:What do I need to install a 40 watt solar panel?
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!
