- Q: I know that if I put solar panels in my home I will get 30% back from the govt. Does that mean if I pay 2K I will get back around a 3K check? Or will my income play a roll where I may not get back as much?
- The energy credits are non-refundable. That means that they only reduce your existing tax liability. If the credit is more than your tax liability, the excess is lost. Examples: If your tax liability is $5,000 and you qualify for a $3,000 non-refundable credit, it reduces your tax liability to $2,000. If you had paid in $5,000, you would get a refund for $3,000. If you had paid in $3,000, you'd get a refund of $,000. If your tax liability was $2,000, a $3,000 credit would wipe it out and the other $,000 would be lost forever. If you had paid in $2,000, you'd get a refund for $2,000. If you had paid in $,000, you'd get a refund of $,000. BTW, check your math. 30% of $2k is not $3,000.
- Q: Can solar panels be used in combination with wind turbines?
- Yes, solar panels can be used in combination with wind turbines. This combination is known as a hybrid renewable energy system. It allows for a more reliable and efficient generation of electricity as the two sources complement each other. Solar panels generate electricity during the day when there is abundant sunlight, while wind turbines generate electricity when there is sufficient wind. By combining these two sources, the system can produce electricity continuously, regardless of the time of day or weather conditions.
- Q: Rated in kilowatts, what is the maximum output of one 8 by 0 solar panel? Assume this solar panel is located at the equator for maximum sunlight.
- 8 by 0 what? inches, feet, meters??
- Q: Can solar panels be used in areas with frequent power outages?
- Yes, solar panels can be used in areas with frequent power outages. Solar panels generate electricity from sunlight, which means they can continue to produce power even during power outages. By installing battery storage systems, the excess energy generated during the daytime can be stored and used during periods of low sunlight or power outages. This allows solar panels to provide a reliable source of electricity in areas with frequent power outages.
- Q: I need to know how solar photovoltaic panels work. Anyone have a good explanation?
- Hey E Girl, photovoltiac panels are pretty simple. They start with a solid block of silicone, and shave thin layers off of them, called wafers. Once you have about 72 of them, you take half of them and dope them with boron, then the other half are doped with phosphorous. Once that's done, they take one each phosphorous and boron wafer, and glue them together with a special conductive epoxy glue, and attach a wire to each wafer. When the two glued wafers are exposed to the sun, a reaction occurs that forces free electrons from the silicone particles from one wafer onto the other, and a voltage is generated between them, about /2 volt to be exact. Once all 36 pairs are glued together, they are wired in series, connecting the phosphourous wafer from one to the boron wafer on the next, and so on. If you start with 72 wafers, you'll have 36 pairs glued together when you are done. At /2 volt each, that makes a 8 volt panel, which is used to charge a 2 volt battery. The charging source always has to have a few more volts than the battery. These 36 pairs of cells are then arranged on some kind of back board, glued down, covered with acrylic glass and mounted in a frame. There are some great websites you can go to for more info, I will list some below. Did you know that there are over 00,000 homes and businesses in the US alone that use some level of solar power to operate their electrical systems? That's good news. We actually live in one of those homes, it is powered by both the wind and sun and heated with solar and wood. I hope this answers your question, good luck, and take care, Rudydoo
- Q: Can solar panels be used in remote areas without access to the grid?
- Yes, solar panels can be used in remote areas without access to the grid. Solar panels generate electricity by harnessing sunlight, and they can operate independently of the grid. This makes them an ideal solution for remote areas where setting up power lines and accessing the grid may be difficult or costly. Solar panels can provide a reliable and sustainable source of electricity in such areas, allowing for various applications like powering homes, schools, clinics, and even small businesses.
- Q: Any opinion on harbor freight solar panels ?
- Yes -- don't buy them. They are low quality solar panels, and the e-z kit they sell produces barely enough power for a lightbulb. The kit they commonly sell is a good child's science fair experiment/project, but do not expect to get your money's worth in solar power. If you are attempting to self-teach yourself on solar panels, this might be a good starting point, if not also a little expensive. But again, do not purchase Harbor Freight solar panels, or their e-z kit. If you are serious about getting into solar panels, there are distributors who will gladly talk to you about what kind of solar panels you will need for a regular house (hint: it is actually a pretty big set of solar panels for even a low power usage home).
- Q: i am working on a project which requires small solar panels. i am looking for ones about 3X4. is there any way i could get these? and where?
- I bought mine from OKorder. They were from a top seller and arrived in better condition than I expected. They are 3 X 6 and have an output of .5 volts .7 watts. You will need other items as well blocking diodes, charge controllers as well as tabbing ribbon and buss wire. Learn about other components you may need at the website below. There is also an OKorder link at the bottom of the page.
- Q: What is the typical warranty period for solar panels?
- The typical warranty period for solar panels ranges from 20 to 25 years.
- Q: Im doing this project on Solar panels and im not so sure what they are!some questions i have are who invented them and what were they invented? If u could know anything on Solar Panels i would love to hear it. Thanks!!!!!!!!!!!!!!!!!!!!!
- Solar Panels are collections of solar cells. These panels basically collect the incoming sun's electromagnetic radiation and convert it into electrical energy. A solar cell is any device that directly converts the energy in light into electrical energy through the process of photovoltaics. The development of solar cell technology begins with the 839 research of French physicist Antoine-César Becquerel. Becquerel observed the photovoltaic effect while experimenting with a solid electrode in an electrolyte solution when he saw a voltage develop when light fell upon the electrode.
