Q:Do solar panels go bad if not used?
I'm answering for conventional silicon solar panels, the only kind I really know. The panels are basically semiconductor, wire, glass, and aluminum housing. The last three, everyone knows have long lifetimes if not exposed to the elements. As for the semiconductor part, the degradation is generally due to exposure to the sun. And even so, some solar panels from the 70's are still working today. Usually, what does them in is failure of a connection due to vibration, degradation of the plastic due to heat, sun, or water exposure, or accidents. The question of how useful the panels would be after 30 years is different, though. I have Germanium transistors from 50 years ago - they're still good, but their specs are really lame by modern standards. And suppose you had a PC from 25 years ago. Original cost, $4000, no hard disk, only runs DOS off a 5 /4 floppy disk. It works great, but except as a curiosity, is it useful? The batteries that most people use to store solar energy are lead-acid. The technology has not changed much in 30 years. If you had such batteries in storage, that had *never* been activated (that it, they were dry, no acid had been added yet), I would not be surprised if they would be fine after that period of time. If the batteries were activated, no, they would not keep. But maybe battery breakthroughs are coming with other chemistries, so those batteries would seem clunky and useless 30 years from now.

Q:Solar panel help please?
Solar water heating is low technology. There are do it your self plans for it all over the internet. There is no electricity involved. Simply laying a garden hose on the ground in the hot Sun can heat the water to really high temperatures. Just have a shutoff nozzle on the hose, turn on the tap and open the nozzle until water comes out and then close the nozzle at the end of the hose. Let the hose full of water sit in the sun for an hour or so and then open the nozzle and feel how hot the water is that comes out. Be careful, because it can be so hot you can get a burn! When the gallon or so that can fit in the hose has all come out and is replaced by other water from the tap, it will feel cold again. Close the nozzle and wait another hour to heat it up again. A solar hot water heater is just a very long coil of pipe in the Sun, maybe with a pump to slowly circulate water from a holding tank so you can make and store more hot water that fits in the hose. Solar electric power is completely different. It uses semiconductor devices called solar cells to make electricity directly from light. Many of solar cells are usually arranged into large panels to make larger amounts of power. In electricity, Watts = Volts * Amps. Battery capacity is usually measured in Amp-hours. Small solar panels are often designed to produce electricity at 2 volts. A 60 Watt, 2 volt panel makes 5 Amps of electric current, because 2*5=60. So if you use it to charge a 2 volt battery with a capacity of 5 Amp-hours it will take hour to charge. A 0 Amp-hour battery would take 2 hours to charge with the same panel.
Q:How much electricity does a solar panel generate?
Actually, there's about 000W per square meter of optical power from the sun. Solar cells cannot collect all of that power though. In fact, most solar panels are only about 5% efficient (though some can be around 20%). So that means a solar panel that is square meter can only provide about 50W, not 000W. And that's only during peak sunlight hours.
Q:How long does it typically take for solar panels to pay for themselves?
The payback period for a solar PV installation is based upon the cost of the installation compared to the savings achieved. Therefore if you installed a modest set of panels yourself, did not need on site electrical storage and did not have any permitting fees but did enjoy rebates you would be doing better than if the installation costs were high, the solar equipment was expensive, you had to purchase storage batteries, it was costly to maintain and permitting was absurd. On the other side of the equation if your electrical use is high, you perhaps own an EV or you can sell power at a high rate then the costs you will be offsetting will be higher and the payback period will be lower. If your electrical use is minimal, there is no time of use metering available the payback period will be higher. Some of the costs you may be offsetting may not be electrical. If you concurrently purchased an EV then you may be offsetting the cost of gasoline which would be higher than electricity. Overall rebates and incentives play a major role. I have seen payback periods as low as 3 years claimed (commercial installation with special city tax breaks) and as long as over 20. A bell curve would probably find most of the installations in the 7 to 5 year category. A solar thermal installation (for hot water, heating and sometimes AC) is far more efficient and most would be in the range of 2 to 8 years.
Q:Parts needed to build a solar panel?
You need to talk to your local power utility to see what they require for you to connect your solar power system into the grid.
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:Will my off the shelf deep cycle battery I purchased at autozone work well with solar panels?
There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
Q:Using a solar panel to make energy?
Small solar panels produce almost no power that matters to anything. A whole square meter may produce 80 Watts when facing the noon sun in Arizona. take that down to 28 Watts in Erie Pa. The 80 Watts can charge a 2 volt battery at about 8 amps times 6 hours, or 48 Amp hours per day in Arizona or perhaps 5 amp hours/day in Erie. The amount of energy you can save declines as the battery is more charged so you need to use up the power stored before you have more to save. To do that charging you need a circuit that will carry 8 amps, including a voltage regulator. So, if your circuit can stand 20 amps the person in Arizona can run 2 square meters of panel. It may seem strange but the same is true for the person in Erie. The person in Erie has to allow for the maximum output of the panel, not the expected average. The person in Erie will occasionally have really clear skies and put out maximum rated amps. The amperage that the batteries can put out at maximum should not be used. That will destroy the battery. One puts a breaker on each output circuit to protect the circuit and a breaker that limits battery output to 20 amps based on a battery rated at 800 amps. That 800 amps is surge capacity. One or two panels does not really justify having this capacity for battery and circuitry. I can think of using it to provide an emergency LED lighting system.
Q:How many solar panels do we need to power the US?
Annual power consumption in the US is approximately .2*0^5 Watt-hours. The average solar panel can generate 80W continuously. We can break up the calculation into parts: .2*0^5 Watt-hours per year 925 hours per year .3*0^ continuous watts 80W per panel 64383566 panels 000 sq. inches average solar panel area 650 million square miles (!!!) To give you a better idea, the total surfacre area of the United States of America is 3 million square miles. The surface of the earth is 96 million square miles. Not even 3 planets full of solar panels would be enough. Maybe it is easier for people to start using electricity more responsibly?
