Q:how much solar panel power do i need?
My guess is that you might discover everything concerning solar power at www.okorder.com.
Q:Hi trying to learn more about Solar panels!?
solar panels collect the suns energy and turns that into electricity that is then stored in batteries. attached to the batteries is another device that takes the power from the batteries and turns it into power you can use in your house. it is a very expensive power alternative.
Q:What factors effect the amount of electricity produced from solar panels?
It depends on what you mean by amount of electricity. Normally that would mean the total energy produced over a given period. In that case, the main factors are ) Efficiency of the solar cells 2) Total irradiation received: incident radiation density times the solar panel area, and the angle of the incident radiation. Item ) is determined by the materials and method of construction of the solar cells Item 2) depends on the location of the panel, both on earth's surface (latitude), time of year, and how the panel is oriented with respect to the horizontal. Altitude of the location can also be a factor. Prevailing weather conditions, number of cloudy days, etc. are important. Independent of these parameters, larger area means more electricity.
Q:Cost and energy generated by solar panel?
A little more than 0 watts per square foot, so that size panel would generate 250 watts under ideal conditions, which is noon on a sunny but not too hot day, near the equator. That's about /3 horsepower, or the same power as a man working hard. That is larger than needed to keep the battery of the car charged, unless you plan to run a laptop or something off it at night. The power is also too small to power the car for driving. If it's an electric car, you could get maybe another 2 miles per day out of the car, again, under ideal conditions. An RV store might have an idea of how much installation would cost. They would be accustomed to solar panels for RV's, but probably not small cars. A panel of that size would cost perhaps $500-800 just for the panel.
Q:Air conditioner 25 volt 5 amps: how many solar panels and batteries to run 24/7?
OK, in addition to the solar panels, you wil need an inverter (DC to AC; 2V t0 20V) capable of delivering 20A continuously and as much as 40A for the compressor starting surge, and a fairly large battery bank capable of delivering something over 2000 watts continuously (losses in the charging and conversion process) as well as the surge. So, if your actual demand is now calculated around 2000 watt/hour, and you need to both run the unit and charge batteries during the daylight hours - and considering that the ideal charging rate for a lead-acid battery is on the order of 0% of its capacity, you will need a huge reserve on the battery section and a huge excess on the solar section to make up for the 5 hours maximum input. So, the average high-quality deep-discharge battery will do about 400Ah @ 2.6V. Which comes to 5040 watts for one hour. For round figures, it will give you 2000 watts for 2.5 hours. You will need a minimum of eight of them just to make your system run for the 9 hours you are anticipating. Given that you do not want to run the batteries to zero each night, a 50% reserve would be a wise investment - comes to now twelve (2) batteries. Now, you will have to make 2000 watts (to run the unit) and also produce and another 8600 (per hour for five hours) watts to charge the batteries for the next night. Again, for round figures, you will need 0,000 watts of solar power, or seventy (70) panels. At ~0 watts/s.f. (00 watts/meter), that comes to about 000 square feet or 00 square meters. Modern non-crystaline panels may reduce this by 20%, or so but no more than that. You will be charging the batteries at roughly 20% of their discharge capacity - which will pretty much cut their service live in half, or so. As the average deep-discharge battery has about an 8-year life span under ideal conditions (and your situation will be far from ideal) you may expect to replace them every four years or so with good care. Much less with no care.
Q:how much money does solar panels save?
What you are really looking for is ROI. Return on investment. If you spend 0K up front how long will it take to recoup that 0k. The answer is too long. Solar panels are not and never have been about saving money. They are about trying to save the planet. So if your school wants to go green then they should do it but the overall cost will be higher.
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:Power tester for solar panel?
Voltmeter.
Q:Where are solar panels used?
Solar panels can be used anywhere in the world. The only requirement is that there is sufficient sunlight to power the solar panels and in many developing countries, solar energy is used to heat water.
Q:Where to get or find information on solar panels?
On my website you can read my story of how my dad made solar panels at home and now he pays nothing to the electric company.
