Production description

 solar panels that can always be pointed at the Sun even as the rest of the body of the spacecraft moves around, much as a tank turret can be aimed independently of where the tank is going.

A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricityin commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. 


Depending on construction, photovoltaic modules can produce electricity from a range of frequencies of light, but usually cannot cover the entire solar range (specifically, ultraviolet, infrared and low or diffused light). Hence, much of the incident sunlight energy is wasted by solar modules, and they can give far higher efficiencies if illuminated with monochromatic light. Therefore, another design concept is to split the light into different wavelength ranges and direct the beams onto different cells tuned to those ranges.[citation needed] This has been projected to be capable of raising efficiency by 50%. Scientists from Spectrolab, a subsidiary of Boeing, have reported development of multijunction solar cells with an efficiency of more than 40%, a new world record for solar photovoltaic cells.

Q: If you need 9400 watts, 75 amps@ 240V, how many solar PV panels do you need?
75 amps @ 240VDC is 8,000 watts.
Q: Can solar panels be installed on airports or transportation hubs?
Yes, solar panels can be installed on airports or transportation hubs. In fact, many airports and transportation hubs around the world have already implemented solar panel systems to generate clean and renewable energy. These installations not only help reduce the carbon footprint of these facilities but also contribute to their energy self-sufficiency and cost savings.
Q: Any recommendations for companies? Any things to look out for?
There okorder / 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: Is there a material that is capable of absorbing enough UV radiation to make it worth using as a flexible solar cell?Not flexible as in aluminum, but a material such as plastic (polycarbonate).
Yes it depends on the material of the bearings fixed, on the to be Moved pivots!/--Fulcrums/turning points/hinges.etc. but the wiring for commands has to reach them keeping them moveable in unhospitibale temperatures.The heating effect of an electric current is benificial too.
Q: I am looking to wire in some solar panels into my home. I already have plenty of wiring, and some solar panels around. I just need to know what I need to do to wire them into my home so I can lower my electric bill. This past month it was six hundred dollars.Can someone direct me to some information, or tell me how without telling me to hire some guy to come out to charge me thirty thousand dollars to install two or three thousand dollars worth of equipment?
The essentials are to connect the panels in a configuration that matches the inverter. My system has twenty 24 volt panels in series, to an inverter that wants to see 480. They could have been in any series-parallel configuration to match an inverter that used different voltage. I chose the high voltage route to reduce IR losses in the connections. The proper inverter is essential on grid connected systems. It must be able to disconnect from the grid if grid power fails, and to come back on line automatically, and in phase. There has to be a fused disconnect between the panels and the inverter. When connecting to the grid, another fused disconnect is required. My power company was very specific about acceptable switches. Just using a good brand doesn't hack it. Lots of good info on solar panels in the green search box above on this page.
Q: so...do you think an online store dedicated to selling solar panels/systems will be a good business idea? Since green energy is the 'hottest' growing business area recently with usage growing about 30% per annum and investors putting all their money into solar energy, wind farms, biofuel, etc. I think when you sell solar systems online this will be the most appealing business model to the end customer...especially if you offer free installation on orders of say $000.
It's that offering installation that is the problem. Do you have the ability to arrange contractors to install where ever the customer may be? The online store model works best on a drop ship model where once you've shipped the parcel, you're done. Online selling of solar panels would be basically to the DIY crowd and as you've said, most people don't have the skills nor the enthusiasm to install them. The current price per watt installed is about $0 a watt. $ per watt are the organic dye and film solar panels which are horrendously inefficient and require much more square footage and that $ per watt price is before installation. Currently solar depends a lot on government subsidies to be worthwhile. The various green energy technologies (both solar and wind) lack the economics to be anything other than greenwashing and often if you consider the total impact to the environment, they are often worse than fossil fuels and even if the environmental impact of their manufacture is neglected, it's hard to compete with fossil fuels where nature has done all the work of storing solar energy in a convenient hydrocarbon form. Of course, there's still money to be made off people's ignorance. You've already asked this question several times, apparently you're not satisfied with any answers that are counter to your hopes. Why don't you try it and see how far you'll get.
Q: i want to charge my mytouch 3g with solar panel(s) it has a 500mah 3.7v 4.4wh batterieswhat do i need to charge it can i use RadioShack 0.5W Solar Panel 4.5V or RadioShack? W Solar Panel 4.5V
see u have to make ur own ckt for this ur solar panel generate DC if u want to charge ur phine then its convenient way to harge with ur charger for this do this search for net to convert DC-AC convertor since ur charger work on AC so when ur solar panel generate DC it convert into AC that will charge ur phone in ckt u need this thing filter and amp ie the DC voltage come from solar panel 2 DC to AC convertor 3 AMP for AC 4 filter for AC and u are done....... fine ckt from google.....
Q: Im doing a science project and I need to know what gases or liquids a solar panel can make that is not friendly to the environment. Please name all the gases and liquids and explain how they damage the environment. It would be most likely that you will get best answer if you find all the bad things about solar energy and explain why they are bad and how they affect nature. that would be helpful to. Thank you
it is fairly conceivable, despite if the difficulty with this physique of recommendations is the storage of the produced HHO. An 'on call for' technique is plenty safer and less difficult. Hybrid structures are already accessible that boost gasoline financial equipment some 20% to 60%. DIY 'plans' and such are additionally accessible for people who prefer to tinker.
Q: What sort of maintenance is required for solar panels....?
All panels should be cleaned to function best. Brush or wash off dirt and leaves. They should be checked for structural integrity and lack of rust. Solar Thermal panels should be checked for signs of leaks and/or discharge from pressure relief valves. Solar Photovoltaic should be checked for electrical function and grounding.
Q: Can solar panels be installed in areas with high levels of saltwater exposure?
Yes, solar panels can be installed in areas with high levels of saltwater exposure. However, it is important to choose solar panels that are specifically designed for these conditions and are corrosion-resistant. This may involve using materials like marine-grade aluminum or stainless steel for the panel frames, and ensuring proper sealing and coating to withstand saltwater corrosion. Regular maintenance and cleaning are also necessary to mitigate the effects of salt buildup on the panels.
