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:A question about central a/c and roof solar panels?
if you use solar panels it will make electric to run anything you want . it depends how much they charge to build the solar system if it makes sense, money wise. but if your asking if solar power makes enough electric to power an A/C the answer is , you bet your azz .. but only when the sun shines Nellie
Q:Solar Panels for Home?
You okorder.com The notion of spinning a meter backward has a lot of people plugging in their solar panel via an inverter- but this is a very bad idea and illegal as well- the power company requires a lockout device they control to kill power in their powlines for servicing and repairs- a plugged in solar panel and inverter can cause them injury or death. If you have about 30,000 dollars to invest (cost will vary), and you are going to be staying in your home for at least 0 years, contact your electric power utility as they will have the progams in place to do the installation on your site, and install the needed equipment for you to be legally grid tied. They will also have your paperwork prepared for your tax person come tax time. Most are actually seeking people out to do this, I won't go into details why, but by listening carefully to the power company in their presentation they will indirectly tell you why. Any installation that is intended to be grid tied MUST be approved by the power company and meet their specifications. Too many people are ignoring this last detail.
Q:Calculate solar panel energy output question?
You have the area of the solar panel. You know their efficiency. What you need to know now is the energy (per area) delivered by the sun. The energy delivered by the sun can be found on the internet. Earth ,43 – ,32 W/m² (wikipedia) That is offcourse for your solar panels perpendicular to the ray's of the sun. If they are under an angle you should see what the area of the projecton of your solar panel is on a plane perpendicular to the ray's of the sun. So know you have the intensity W/m² and an area (or effective area). Here you go the energy deliverd by the sun. And 30% of it is what you get out of your panels.
Q:Help with solar panels?
With a small house it may not be necessary to put solar panels in it. The wattage that is needed will not be much of a difference when using electricity.
Q:Is getting solar panels worth it for your home?
There okorder.com/ Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q:Can I plug a solar panel into a wall socket to lower my electric bill?
The other responders have given partial information. The electricity in your house is 20 volts AC and the solar panel will produce DC voltage. If you plugged in the solar panel into the wall, the solar panel would be destroyed, possibly with disastrous results. If you connected the solar panel to a DC to AC inverter, there are also dangers. The solar panel unless very large will not produce enough power to make a lot of AC, for every amp of 20 volt AC, you require more than 0 Amps of DC voltage. So most small solar panels are used to trickle charge a 2 volt battery used in backup situation. The problem is that the house AC and the inverter AC have to be exactly in phase or again you have disastrous results. If they are exactly 80 degrees out of phase, the wires now are carrying 240 volts and you will burn out the inverter, and possibly cause a fire. There are systems that will synchronize an inverter to commercial power so that you can feed the power back to the grid, but these are more complicated. If you want to use the battery and solar panel to run some lights during power failures, then you can connect the light to the common terminals of a switch, but the switch must be a break before make switch, which means that when you throw the switch the common is disconnected from the one source before it is connected to another source. Most AC switches will do this, but make sure.
Q:What is the principle of solar panels work?
Solar power generation There are two ways of solar power generation, one is the light - heat - electricity conversion, the other is the optical - electrical direct conversion.
Q:What are the properties of Solar Panels?
The main property of solar panel is to convert solar energy into electrical energy. Solar panel has been made to convert solar energy i.e. natural energy into electrical energy. A combination of solar cells together forms a solar panel. Solar panel converts solar energy into electrical energy. Solar panel depends on natural and free resource rather than paid resources. Easy to plant. Low cost. Long lasting. Pollution free.
Q:Amount of solar panels needed to run a/c and pool pump?
Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.
