Q:hi so im doing a school project thing and they have a lot of different questions for us that help us decide whether we would rather a city have a nuclear reactor, or solar panel. But i cant seem to get the last 2 questions...help please???so question ........What types of emissions, if any, are produced by each type of generating station? Do these emissions affect human health?question 2.....What are the long term financial costs associated with maintaining each type of generating station?thanks!: There's no standard nuclear reactor, but if we take a GW nuclear plant, it can generate about 8 terawatt-hours/year. A 200 watt solar panel can generate about kilowatt- hour/day, or 365 kwh/year, so that's about 2 million 200 watt solar panels. However, the power output from the nuclear plant is controllable by the operators, where solar panels only operate at full output for a few hours/day (on clear days - less if there's cloud). Therefore, to compare the two, you have to factor in some kind of energy storage or backup which will increase the cost of the solar installation (perhaps by a factor of two or more). Despite claims of solar being cheaper than coal now, when one compares apples to apples (i. e. total energy produced, and controllability) solar is still several times more expensive than coal, and about twice as expensive as nuclear even in the U. S. A gram of U-235 can make usable energy equal to three metric tons of coal. Solar energy production has no hazardous by-products, but manufacture of the panels can involve some very hazardous materials like fluorine (for silicon panels) or cadmium (for CdTe panels). This is part of the reason panel manufacture has gone to Asia - they have fewer environmental regulations and it's easier to dispose of the byproducts of production. DK

Q:I got a really great deal on 2 houses because they were fixer-uppers. I'm living in one and the other I'm renting out. However, the previous owner did everything himself in 950 95, so needless to say, things are not to todays standards. Both houses need rewiring (there are no ceiling lights, few outlets, and mine has two old fuse boxes and the other has a breaker box but it pops the breaker a lot). The only reason they are still functional is because both houses use natural gas for water and heat, so otherwise, they electrical work is getting us by, but who knows for how long. I thought that maybe instead of redoing the electric, that I could just add solar panels to compensate for the small electric boxes. Also, since I would have to hire electricians to do all the work, which would be more cost effective (not including the decrease in utilities since I don't pay the utilities in the rental anyways)?: No. solar panels would not solve your problems and are usually not cost effective. Solar panels will not help to compensate for undersized electrical service. You would still have to upgrade the existing service. Once that is done you should have no problems and all the electricity you need would come from your power company. Have an electrician come out and do an inspection and tell you what all needs upgrading. Solar panels would save you money on the monthly power bill but the cost to install them would be higher than your savings. If it made economic sense to have solar power then everybody would be doing it. That's why you see very few houses with solar panels on top.

Q:Can solar panels be installed on a church or place of worship?: Yes, solar panels can be installed on a church or place of worship. Many religious organizations have taken steps to embrace renewable energy and reduce their carbon footprint by installing solar panels on their rooftops or open spaces. Installing solar panels not only helps to generate clean and sustainable electricity but also serves as a visible symbol of the organization's commitment to environmental stewardship.

Q:I live in Sacramento, CA, and I need some solar panels for a project fo school. They don't have to be very big......just something that I can use as an example.Thanks!: Trees, they have plenty of leaves. You'll probably have to buy an educational kit from Radio Shack or something like that. Maybe break some old solar powered calculators open.

Q:What is the proper diode to use on an 5v 500ma solar panel?: At least a 2 amp diode. rated above the 2 volts that are commonly found on the market. A blocking diode must be able to stop a higher current and voltage than the panel maximum. A diode will work on any voltage and current lower than it rating.

Q:If you were to shine, for example, heat lamps onto the solar panel along with the sun, will the solar panel eventually not work? Or will they produce more light as long as more light is directed onto them.: Solar panels have a upper temperature limit, and it's only a bit more than it would reach in a very bright sunny day near the equator. Start shining heat lamps on it and you will raise it past it's max temperature, and it will die. .

Q:I have a 20 watt solar panel that I want to set up. I need to connect it to the solar controller but do not know what cable to use. I plan on adding more solar panels down the line. What would be the best cable to use?: on the controller, it writes which would be related with image voltaic panel which would be related with battery which would be related with load all of it write on the image voltaic controller. only see the controller

Q:Can solar panels be installed on a shopping mall or retail complex?: Yes, solar panels can be installed on a shopping mall or retail complex. In fact, many commercial buildings have already embraced solar energy as a way to offset their electricity consumption and reduce their carbon footprint. By installing solar panels on rooftops or parking structures, shopping malls and retail complexes can generate clean and renewable energy, leading to cost savings and environmental benefits.

Q:Can solar panels be used in areas prone to hurricanes or earthquakes?: Yes, solar panels can be used in areas prone to hurricanes or earthquakes. However, they need to be properly installed and reinforced to withstand the potential impact. Additionally, in areas prone to hurricanes, it is recommended to have a plan in place to secure or remove the panels before the storm hits to prevent potential damage.

Q:Hello,What do you all think about the future of solar panels and what role they will play in the near future. There is tons of money being dumped into the industry and demand is slowly rising. Also do you have any favorite solar links to get more info about them?: Solar Panel really isn't any new technology, it was discovered in the early 60s. And as you can see it hasn't progressed all that much. But Developers are saying that within the next five years solar technology will increase dramatically. With more and more people looking for greener and easier forms of energy, there are many looking towards solar. In fact some energy companies are willing to buy the energy that you produce from you. And with new forms of thinner silicon panels, we are looking at a more efficient kind of panels. Unfortunately for us, at the moment thin-film panel silicon isn't as efficient as we are looking for. They are flimsier than the traditional panels and do not contain as much silicon to produce the electricity. But as soon as the demand increases, the production will increase, and if more companies are looking to invest in solar, then there will be more competition, with more competition- we are going to have improved technology, and with more improved technology, the prices will go down. Because at the moment, there is not much of an incentive for solar power. Compared to the Kilowatt- hour produced from coal and other forms of energy, solar does not produce as much. Experts are saying that within the next five years, not having solar panels on your house will be as silly as building a house without plumbing. The future on solar panels looks bright.
