Q:Can I hook up a Solar Panel to a car battery? Does it matter the kind of car battery?
Those answers are partly correct. You cannot recharge two 2 volt batteries in series with a photovoltaic panel with an open circuit voltage of 8 volts. You possibly over charged your 7.5 AH battery with a 00 watt photovoltaic panel, which can supply 8 amps to the battery with unusually bright sun light = fully charged in one hour. More likely you did not charge the battery for a month or more which killed it. Also discharging below 2.6 volts shortens the life of the battery, or short circuiting the terminals even briefly. Yes a deep cycle sealed lead acid battery rated 2 AH is likely the best unless you buy a 00 amp hour marine battery which weighs about 80 pounds and will take at least two days of bright Sun to fully charge.
Q:Question about using solar panels?
If okorder.com and they ship across the US and Canada.
Q:Do it yourself Solar Panels?
Firstly, forget about making your own PV panels, while you can (if your chemistry is up to it and the home lab well tooled up) make a small PV cell, the efficiency will suck and you will never make enough to produce a reasonable amount of power. What you can do is to build your own solar thermal system to produce hot water (solar thermal makes better sense then PV in most domestic situations anyway), black painted central heating radiators under perspex, rockwool behind, small pump running a water/glycol mix through a heat exchanger controlled by some trivial electronics... Job done. As long as you don't try to run too hot, you can get a hundred watts or so of heat per square meter from such a solar thermal plant. Regards, Dan.
Q:how many solar panels?
If he lives in a sunny area, he should contact a local solar installer about getting a grid-tied solar system to offset his electric bill. It's not necessary to supply all the electricity from solar. The system will work seamlessly right alongside grid electricity, and your father can choose whether to supply 20% of the electricity or 99% by sizing the system appropriately.
Q:Need help with building a project involving solar panels?
Solar panels are designed to be used to recharge a battery or series of batteries, not for direct power. That is the inherent weakness of solar systems. The only way to have it work in low light conditions if to have several cells wired in series and have a voltage regulator to limit the amount of voltage that can be supplied. Other than that, add a battery and a charging circuit that the cell would supply power to.
Q:What do I need to install a 40 watt solar panel?
Whats the size of battery ? The time needed for your 40Watts panel to fully charge a battery depends on the size of battery. Usually battery size is mentioned in Amp-Hours (AH).
Q:Infra-red solar panels?
Solar panels work when the metals from which they are made release electrons when hit by radiation. There is a threshold that, below a certain wavelength/frequency, they do not eject electrons. As frequency increases, more electricity flows. Radio and infrared are the least energetic electromagnetic waves.

Fuselage, solar panels are boring...check out the design considerations for the fuselage of the old SR-7 Blackbird, a really amazing aircraft in its day.
