Q: I read on CNN's website last year some company was creating a very cheap type of solar panel, that needs minimal maintenance and and has minimal glare from the sun. And the creator of the project said he one day wanted to cover every rooftop in the US with these solar panels. Seems like a good idea to me but I havent heared anything of it for a long time and I don't know what they are called... any help?: Solar panels are one of the hottest areas in materials research today - from basic science to applied production techniques. There have been major strides in thin-film manufacturing technique as well as silicon technology. There's not a lot of hype about it because solar panel manufacturers don''t really need to advertise yet - they are selling at factory capacity with demand for more. Standard silicon solar panels now sell for around $3 a watt, and grid parity is expected within 5 years. Reference is to the MIT Technology Newsletter, which runs several articles a month on new solar tech.

Q: this solar panel i saw was for 500 dollars(i get a 25% discount)and i was curious will they produce electricity? or just heat?what do they do?is it a good investment?here is a link to the one i would like, no reviews but it looks new to the site.: Solar panels produce electricity. This one isn't very good. $500 for only 80W with such a large panel? It doesn't even come with a battery (car battery) If you're thinking of something to try and run your house off of, you'll need somewhere between 2 to 24 of these panels, plus a voltage converter and other equipment to connect it into the electrical system in your house. If you want something to help charge a cellphone, I guess this would work - if you could get the electrical connections set up properly - but it's still awfully expensive and won't give you a return on investment for somewhere between 5 to 20 years - by which time the panel will need to be replaced, and we'll (hopefully!) have more efficient panels available.

Q: How do solar panel power systems work?: There are two kinds of solar panel power systems, one is on-grid solar power system, the other is off-grid solar power system. The on-grid solar power system: the solar panel convert sunlight into DC electric, and the DC electric is converted into AC electric by inverter, one part supply for the household load, the other supply to power grid. The off-grid solar power system: the solar panel convert sunlight into DC electric, and charge for the battery or supply for the DC load by controller, if have AC load, it need a inverter to convert DC into DC.

Q: I really would like to have my own solar panel, but i don't know how. Most of the panels i have looked at are for car batteries but i'm not sure how this would be able to be transfered into electricity. I'm looking to power things like lamps, a stereo and various chargers for phones and ipods. Please explain to me how i could adapt a solar panel to my uses. Thank you.: Yes, it can. Now what do you expect out of it? It can reduce your electric bill by some amount. That amount depends on how many solar panels you install and how sunny your days are. You have to pretty much cover a roof to get a substantial electric reduction. There are 2 companies where I live that have installed solar panels and covered most of their roofs with them. They've reduced their electric bill by about 30%. It's expensive to do this. Don't expect a fast pay back. In fact you may save more by using solar heating panels for hot water than by using solar electric panels. I think it's cheaper as well.

Q: Can solar panels be installed on a residential community or housing complex?: Yes, solar panels can be installed on a residential community or housing complex. In fact, many residential communities and housing complexes worldwide are adopting solar power as a sustainable energy solution. Installing solar panels in these areas can help reduce electricity costs, decrease reliance on the grid, and contribute to a greener environment.

Q: By best I mean safest places. If I were to install them on my roof am I risking due to damage from weathering? Such as rain or snow. I don't get very high winds around here, nor any natural disasters such as hurricanes or tornadoes. Does anyone have solar panels that have been durable for a long time? Is it worth the investment?: Probably not worth it. Sure, it is a great idea, but it will take decades to get your money back in energy savings. Today's panels are fine for a roof. However, I'd worry a little about the interface (where leaks could occur) especially in a retrofit. They, of course, will need to face south.

Q: I have an inverter and a battery 20 Amperes.Daily sun shine approx. 7 Hours.Do I need to buy anything or should I connect the solar panel to the Battery direct?: connect the solar panel to the Battery direct during the day time that's how it works in ALL situations !

Q: Are solar panels suitable for all types of roofs?: No, solar panels may not be suitable for all types of roofs. The suitability of solar panels depends on factors such as the roof's orientation, pitch, shading, and structural integrity.

Q: Can solar panels be installed on a government building or facility?: Yes, solar panels can be installed on a government building or facility. In fact, many governments around the world are actively promoting the use of renewable energy sources, including solar power, to reduce their carbon footprint and promote sustainability. Installing solar panels on government buildings not only helps in generating clean and renewable energy but also sets an example for the community and encourages others to adopt green energy practices.

Q: i took some solar yard lights apart and put them together in a series. i was told if you take AMPS times VOLTS = WATTS. do you test it with ac volt or dc volts? I tested mine with dc volts and got 4 volts in good sun and had my meter set on Ma or milliamps and got .83 which i am asuming that is .83 of one amp now i took those and multiplied .83 times 4 volts to = 34.03 watts. Is this large enough to charge a car battery in a day? And doese it make a difference for amps on how fast it charges or watts. i also was looking around and found 30 watt panels but had higher amps. I am very interested in building solar panels but i realize i dont know what i need to do to make shur they are big enough. my panel is only 9inch by 0 inch. It seems weird that i am putting out 4 volts: If a car battery contains 50 amp hours of charge at 2 volts, that's 600 watt hours of energy. divided by 34.03 watts, 7.63 hours to charge completely in direct sunlight. You don't want to connect them all in series. You want about 4 or 5 volts to charge a 2 v battery, so you should connect groups in parallel, and connect those groups in series to make your voltage. You'll end up with the same amount of power, lower volts and higher amps. It will work for trickle charging your battery if it's not too far run down.
