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:Can solar panels be installed on a data center or technology facility?: Yes, solar panels can be installed on a data center or technology facility. In fact, many data centers and technology facilities around the world have already adopted solar energy as a means of powering their operations. Solar panels can be installed on rooftops, parking lots, or nearby land to generate clean and renewable electricity, reducing the facility's reliance on traditional power sources and lowering its carbon footprint. This not only helps in reducing energy costs but also contributes to a more sustainable and environmentally friendly operation.

Q:Are there any risks of fire associated with solar panels?: Yes, there are some risks of fire associated with solar panels. While solar panels themselves do not catch fire, there have been incidents where electrical components, such as faulty wiring or inverters, have caused fires. However, the risk is relatively low and can be mitigated by proper installation, regular maintenance, and adherence to safety codes and standards.

Q:how does solar panels work?: Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect. The photovoltaic effect arises from the properties of the p-n junction diode, as such there are no moving parts in a solar panel.

Q:Can solar panels be used in areas with frequent thunderstorms?: Yes, solar panels can be used in areas with frequent thunderstorms. While thunderstorms may temporarily reduce solar panel efficiency, modern solar panels are designed to withstand harsh weather conditions, including lightning strikes. Additionally, thunderstorms also bring heavy rainfall, which can help clean the solar panels and improve their performance.

Q:Can solar panels be installed on a recreational vehicle (RV)?: Yes, solar panels can be installed on a recreational vehicle (RV). Installing solar panels on an RV allows for the generation of electricity from sunlight, providing a renewable and independent power source while on the go. This is particularly useful for boondocking or camping in remote locations where access to traditional power sources may be limited.

Q:Can solar panels be installed on a community center or recreational facility?: Yes, solar panels can be installed on a community center or recreational facility. In fact, these types of buildings are often ideal for solar panel installations due to their large roof spaces and high energy consumption. Installing solar panels can help these facilities save on electricity costs and promote sustainable practices within the community.

Q:Solar panels are costly.Do you know any inexpensive way?So that i can make one of my own.: There are a couple other methods under development. One uses a fan inside a cooling tower and a large area covered with black tarps. The heated air can only escape through the cooling tower in the center of the site. The air movement turns the fan blades that spin a generator. Another solar generator uses mirrors that track the sun and focus their energy on a large pipe. I don't recall the contents of the pipe, but the superheated material is used to boil water generating steam to spin a turbine/generator. Neither of these are small scale projects, and are probably far more expensive than what you're looking for.

Q:I have an off-grid 24volt existing system using 8 x 80 watt 2volt, wired at 24volts, mono solar panels with deep cycle batteries,operating now. I have been given a 240 2volt polly cryst. panel. Can I add this panel to existing panels as above. Thank you, dumb solar man: Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!

Q:What is the efficiency of modern solar panels?: The efficiency of modern solar panels typically ranges from 15% to 20%, with some advanced models reaching up to 22%.
