Q:Solar Panels question?
maybe you ought to ask a solar installer in your area. who knows what the electric rates are. and how much electricity you use. and how much sun there is. and what your electric utility's policy is. and what kind of house you have, and how you use electricity. and what appliances (eg stove) you might convert to electric to take advantage of solar panels. wouldn't that seem to be a good idea?
Q:Advantages and Disadvantages of using solar panels?
Initial cost , space occupied AND DAILY CYCLE (unless through a battery) are the only disadvantages. REST ARE ALL ADVANTAGES
Q:Where do I find solar panels?
Home systems start at $30,000 and go up. There are federal income tax credits to help offset the cost, but you still have to pay up front, more than the average person can afford.
Q:Solar Panels heat absorption?
Solar photovoltaics require light, any kind of light. A torch would work, for example. The effect of concentration depends on the amount of light and the material you're shining it on. In CdTe, warmer temperatures and more intense light may lead to better performance. In silicon I think the opposite is true (I don't know though, I've only done research work with CdTe). It depends on properties of the semiconductor, like its band structure. To get an 'order of magnitude' estimate, you may assume a constant efficiency of solar cell so total amount of light (= area * intensity) largely determines the output in standard operating conditions.
Q:Solar Energy Panel VS. Energy Efficient Bulbs?
It's giving off a good chunk of its energy as light in the range 800-00nm which the solar panel can efficiently harvest into electricity. As a lightbulb though, this energy is being wasted because you can't see light of those wavelengths!
Q:solar panels on housing developments?
Solar Panels in housing developments is not being used because it would add $25,000 to $40,000 to the price of the home. Most people in the USA don't understand that after a few years the solar electric panels will start paying them back. It is not just the upfront cost. People would rather spend that 40K on somthing smart like a new corvette. Which has no pay back at all then something stupid like solar electric and helping themselfs or the rest of the world. So if the builders were to add them to the house people would just buy from another builder and the one adding the solar roof tops would just go broke. The State would have to find a way to credit the buyer or buider enough to make it worth it. Is it not more fun to spend millions on finding out where Anna Smith is going to be barried? Or maybe billions on top of billions on War? If we had spend the money on solar that we have spend on Iraq alone we could have put solar on every roof top in the whole USA and had few billion left over. Think about it.. 200 million people in the USA with three to a home would be 66 million homes. It would have only cost 528 billions dollars to put a kWh Solar Electric system on each house in America. But that would be stupid. War makes more money. We don't want Exxon to go broke do we?

Q:where to find used solar panels?

Q:How big of a solar panel system would I need to get ?
Since you are consuming 500 KiloWatts*hours (.5 MegaWatts*hours) per month on average, you need to find out how many KiloWatts per day, so 500 KWh*h / 30 days = 50 KWh per day. With an average of 2 hours of sunlight per day, or even more conservative of 0 hours of sunlight per day 50 KWh / 2 hours = 4.667 KW solar panel system 50 KWh / 0 hours = 5 KW solar panel system An average solar panel is 200W to 250W, so 5 KW / 200W = 25 solar panels 5 KW / 250W = 20 solar panels Solar panels are currently about $ per Watt, so 5 KW of panels is $5,000 A 5KW inverter that is about $5,000 Other incidentals are about $2,000 Total cost (not including labor) is $2,000 Price per KWh is about $0.0 per KWh for East South Central states. Savings per month is *at least* $50 since there are other charges in your electric bill other than usage that are tied directly to your usage as costs. So $50 / month * 2 months = $,800 per year $2,000 investment / $,800 per year = 6.67 years or 6 years, 8 months to pay off the system. Contact many Solar contractors in your area for competitive pricing of labor and for a more detailed analysis of your home.
Q:Why only Photo-Voltaic solar panels?
Just read some of the other posts and I am surprised at the answers. Solar thermal systems typically have a payback of less than seven years on residential system without the tax break. A complete system can be installed for about 5k or less. Compare that to 20k or more for PV with a fifteen to twenty year pay off. Each home and area is different so a site evaluation must be done for exact figures and pay offs. I am going off my own experience in my above statements Flat panel collectors work well in most areas for DHW. Evacuated tubes often run too hot which works well for some applications or high usage. Heating water is the single greatest energy usage other than space heating and cooling. It often surpasses the two above systems based on its widespread usage(every houshold in USA has one) and its the amount it is used(24/7@365) The amount of energy spent to heat water is by order of magnitude the greatest number out there. Having a solar thermal system providing hot water for a average American household is equivalent to taking 40,000 miles off the freeway in a car every year. The BTU's required to heat the water is huge. So why is this more developed cheaper and more efficient technology behind PV in awareness? Natural Gas the number one choice for heating water is cheap. It's by product is invisible and misunderstood. What I find fascinating is if you look at the increase in Natural Gas vs Electricity you will be surprised by how much it has jumped in the last seven years. It is not talked about nearly as much as electricity It does not get the same level of press that PV does. So in short the answer is cheap Natural Gas prices and public perception of this product have kept it off the list of many that are turning toward the green trend. It is less sexy than watching your meter spin backwards. It is the best improvement at the best cost except for conservation which is and was the most cost effective energy saving that can be employed
