Q:Solar panels for a small gym outside my house?

Q:solar panel design question?
Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
Q:How much do solar panels usually cost?
You can log in alibaba,i purchased about 20000watts 2 years ago and solar panels work efficiency is fairly high. I hope my answer help you !
Q:How to Compare Solar Panels?
The short answer is nobody does. Solar panels just generate electricity and only when the sun is shining. What you can do however is sell the electricity you have generated to your local power company. Computer solar panel for using computer and how much volt support?
Q:Solar Panel Current=Battery Current+Load Current?
complex task. browse in google and yahoo. that could help!
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?
Q:Is it worth installing solar panels on a house that has no South-facing roof?
The answer is NO. We can install PV solar panels to properties that are South East – South West facing. Of course it helps if you are 00% South facing but it’s not the end of the world. In fact I would say that the majority of solar panel installations across Britain are not 00% South facing.
Q:5kw Solar Panel Roof Kit?
This is dependent on sun angle, clear sky, shadow interference, clouds, etc. First if you purchased the PV panels and they are rated for 5 kW, the factory rating is based on a particular incident energy, 000 watts/square meter, 25 degrees C and an AM of .5, reaching the panels. It is more likely that you will not obtain this same level in the open air. If we assume you will get 80%, then the maximum kW would be closer to 4kW. This will be produced during peak, clear days with the panels placed perpendicular to the sun at all times during peak radiance times. When the sun first comes up and later when it is going down, there will be more than the thickness of .5 atmospheres between you and the sun, so the radiant energy hitting the solar panels drops off. Total energy is watts time hours. I would expect you PV system to produce about 750 kW-Hr of energy during a clear summer day at peak solar height. Hope this helps, NewtonLaw
Q:Does a 50W solar panel generate 540kWh?
running six hours a day doesn't mean much. You need to look at the solar insulation charts for your school's geographical location to come up with a better factor. The easiest number for you to use is sun hours. For example, Washington DC averages 4.23 hours. Do a Yahoo search for sun hours and you should find lots of charts. Solar panels rated at 50W give this output at full sun near noon at full brightness (no clouds). The sun hour factor makes it easy to find the equivalent number of full brightness hours. So, using Washington DC as an example you have: 000 panels * 50W * 4.23 sunhours/day = 634kWh a day on average. You state your school uses 88240kWh/month which is 6274kWh a day. This would mean you need ten times more solar panels since there is no way to get more daylight. Be careful to put in all the units in your formula and cancel them out to make sure you don't end up with a nonsense result. The title of the question would be answered as followed: 50W/000 * 4.23 sunhours/day = 0.63kWh/day or 9kWh per month or 228kWh a year. These are annual averages. If you wanted a specific month, you would need the sun hours for that month. Hope this helps.
Q:South facing solar panels?
You want the panels facing south because that is where they would get the most sunlight throughout the day. If your front door is facing north, then the back of your house would be facing south, right? So put them up in the back where they are facing south...haha wtf..
