Q:Do you need to pay for electricity if you have solar panels?
Okay--here it is (without the techie buzzwords!) Solar power has a start up cost--the panels and related equipment. But the amount it cost to operate is virtually zero--pretty much jsut servicing th equipment o keep it working properly--much as you do any other appliance. How much electricity you will still have to buy depends on four things: a) how much your system can produce. If you have a 4000 watt system, you'll still buy a fair amount of power. Abigger one--and you will need less from the power company b) how efficient you (your home and appliances are). The more efficient, the less electricity you use. Obviously, things lie CFL bulbs are very helpful here c) Are you willing to invest in a battery storage system to store electricity from the system for use at night? Right now, that's still pricey. But these are starting to come on th emarket more. If you aren't ready to do tha tnow, you can always add it in later. d) can you sell excess power back to the power company.? In California, the law requires utilities to do this--but its not a universal yet, so it depends on where you are. How this works: you are still hooked up to the power company. Any time you need more power than the solar system produces, yur system jst draws it off the power grid--jsut as always. But--any time you are using LESS than the amount of power your system is producing, the excess automatically feeeds back into the electric grid and a special peter credits you with the power. There are cases wwhere people have goene on a long vacation in California and when they got home, the power company owed them several hundred dollars! You'll need to do some research, price thngs, take your own lifestyle into account, and decide what the best choices for you are. It sounds complicated--and to an extent it is. But the reason is tha tyou have a lot of choices tha tyou can make work to your advantage, instead of jsut writing a fat check to the power company every month!
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:Solar Panel experts...please help.?
Unfortunately, I can't give you a lot of specifics on what you should use. However, I can tell you that the very best system for you simply might not be available to you, in which case it really doesn't matter how good it is. Your best bet would be to talk to a supplier in your area and see what is available, THEN start looking at the differences between those. Unfortunately, solar panels aren't quite to the point of being a common-place product...yet. Another thing to consider would be how old your roof is. You might want to look into the possibility of building-integrated materials if you are in need of a new roof. Talking with somebody who sells the panels in your area will help you understand a lot more than just doing raw research. Get their take on it, then fact check and research what they tell you so you know you're not getting ripped off.
Q:solar panel, dc light help?
No longer just any bulb will work on DC power. Any light bulb that's for 0voltage won't work on DC energy due to the fact that the element has too much resistance for a DC vigor provide to create ample heat to generate mild from the aspect. Nonetheless the do make mild bulbs that are designed to function on a DC energy supply and i might extremely recomend making use of the proper bulb with the proper vigour provide. Purchase some 2volt bulbs to be dependable......

Q:Is there anyone trying to create a cheaper and more efficient solar panel?
The cheapest will be solar paint where you lay down some wires and paint the panel on. Solar roof tiles are also coming along but each tile has to be wired in. Currently the target is $ a watt. The efficiencies of these panels are very low but if the cost is low enough then the efficiencies won't matter. Keep in mind that even fossil fuel is solar power, just solar power captured by photosynthesis millions of years ago, and photosynthesis has a maximum theoretical efficiency of 6.6% with most plants achieving less than % efficiency so even an inefficient solar paint already outstrips our current energy sources in terms of efficiencies. The real problem is the business model. With solar energy you can sell the panels upfront but then what do you do for an income whereas with fossil fuels, you sell every kwh and bill each month.
Q:What do you know about solar panels?
Solar panels are made up of lots of solar cells. They don't give loads of energy. A line goes around the cells and... that's all I know lol
Q:Could solar panels contribute to global warming?
I highly doubt it because they don't trap heat like carbon gas does in the atmosphere. Fossil fuels are literally destroying this planet and could eventually be it's demise it we don't accelerate it's elimination. If we could make the clock turn back to the early 20th century and focused on harnessing the sun and wind instead of burning fossil fuel as a means of transport and energy, we wouldn't even be talking about global warming or air pollutants that contribute to global health every year. The only thing the black panels to is create a darker surface but not much different than natural colors like dark dirt, dark green grass etc.
Q:How do solar panels and their battery backup systems work?
The photograph voltaic panels in straight forward terms produce any potential whilst the sunlight is shining. they can't furnish any potential at night or whilst it somewhat is cloudy or wet. The panels can in straight forward terms can charge to the batteries the surplus potential you're no longer using for the period of the easy sessions. The Battery financial business enterprise ought to be sized such that it will furnish all of the potential whilst the sunlight isn't shining. In some factors the place you have distinctive cloudy days, the battery financial business enterprise ought to be very great. The photograph voltaic panels ought to be sized such that they are going to furnish all of the potential you have chose during sunshine cases, PLUS adequate extra to can charge all of the batteries adequate which you might have potential for the period of the night and cloudy cases. My buddy in Mexico has a stand on my own gadget for his domicile because of the fact there is not any grid potential obtainable the place he lives. He has invested over $50,000 and nevertheless ought to run his back-up generator some. He lives in Sonora desolate tract the place the sunlight shines all of the time. He has sixteen photograph voltaic panels and 24 of those golf cart batteries, plus a 0KW back-up generator. He could elect to have grid potential!
Q:How many wind turbines and solar panels does the world need to replace coal, oil and nuclear power?
There is an abundance of free energy available on this planet. Wave, wind, solar, (underground), and many many others that I can't remember right now. If some of the multi-trillions currently being spent being spent by the US government on defence (and the rest of the planet defending ourselves FROM the US) were re-directed towards exploiting sustainable, long-term energy supplies, then much work would be generated and the cost of energy would drop significantly - in the long run. So, why are we not utilizing these sources of energy? Unbelievably short-sighted right-wing political ideology, that's why! One thing almost never reported about nuclear power, is that there isn't much nuclear power fuel available on this planet. I think I can quite honestly state that when the time comes when we are forced to move from non-renewable to renewable energy production, it will probably be far too late with far too much damage done and the environment will collapse and become incapable of supporting oxygen breathing life-forms. I concluded many years ago that capitalism will probably end all life on this planet one day. Capitalism IS right-wing politics! Do you now see where the problem is coming from?
