- Q: when solar panels have served their purpose, what is done with them?

- Q: Can I add more solar panel let say up to 200 watt and adding two 2 volts battery using the same charges controller and power inverter?
- If you put a black panel on the ground or on your house and don't connect it to anything, it will absorb solar energy (heat) during daylight and release it at night (radiation). Not exactly. Assuming the black panel establishes an equilibrium temperature, it's going to be losing exactly as much heat as it's receiving during the day. Some will radiate out into space, some will conduct or convect into the atmosphere. As a wild guess, maybe 50/50. If you hook up a solar panel in the same place but hook it up to batteries, charge the batteries during sunlight hours and using that energy to electrically heat the home at night. The panels will absorb solar energy during the day but will convert that to electrical energy in the batteries instead of radiating it back into space at night. The panels are only about 4% efficient, so it's the same situation as the pure black panel for 86% of the energy. The remaining 4% will get stored in the batteries and then converted to heat at night. That heat will eventually leak out of the house and warm up the Earth a tiny bit. I think it's much the same situation either way. With the black panel the energy gets radiated / conducted/convected right away. With the solar panel a small percentage is stored and not so much is radiated, mostly conducted and convected. You're partly right as a black panel is going to radiate more into space than a house. But you're taking about maybe some day about 4% of % of the differening radiation/convection/conduction fraction, of the Earth's surface area. Probably not significant.
- Q: Can solar panels be used for powering an airport or transportation hub?
- Yes, solar panels can be used to power an airport or transportation hub. Solar energy can be harnessed through photovoltaic cells in solar panels, which convert sunlight into electricity. By installing a sufficient number of solar panels on rooftops, parking lots, or open spaces in these facilities, it is possible to generate enough clean and renewable energy to meet a significant portion of their power needs. This not only helps reduce carbon emissions and dependence on fossil fuels but also lowers operating costs in the long run. Many airports and transportation hubs worldwide have already adopted solar power as a sustainable energy solution.
- Q: About how much would it cost to purchase and install solar panels for the average American house so that the house can be off the power grid and use the same amount of electricity as it normally does?
- I had a survey of my home and it was estimated at $30K with a 30% rebate from the government. It would take about 5 years to pay back the cost. I elected to go solar water heating instead. 2 panels with piping installed to an 80 gallon electric water heater with an internal heat exchanger. One small photo voltaic panel to run the pump. There is ethylene glycol inside the pipe and it circulates and heats the water. Works excellent. I live in Nor-Cal and we get a lot of sun. I need to comment on another statement that photo voltaic cells cost more energy to produce they generate. Maybe once but not true any longer. {Solar cells and energy payback In the 990s, when silicon cells were twice as thick, efficiencies 30% lower than today and lifetimes shorter, it may well have cost more energy to make a cell than it could generate in a lifetime. The energy payback time of a modern photovoltaic module is anywhere from to 20 years (usually under five)[9] depending on the type and where it is used (see net energy gain). This means solar cells can be net energy producers, meaning they generate more energy over their lifetime than the energy expended in producing them}
- Q: Are photovoltaic cells the same as solar panels?

- Q: Dear Friends, I am very much worried about Global warming, So to contribute something for reducing Global Warming I have decided to use Solar Panels. Can anybody tell me what is the price of these Solar Panels and why people are not using them when they are environment friendly. What are the Pros and Cons of these Solar Panels?
- Solar okorder / And thin film solar panel power stations are about 50-60% cheaper now than solar power was in 2000. But they're still not economic in most places. Mike K's claim that solar panels produce more pollution than 'traditional' power is wrong. Coal is over 900g CO2/kWh, plus loads of pollution. Gas is ~400g CO2/kWh.
- Q: where can i get some solar panels for a camper trailer
- I think this is what your looking for.. For future reference all I did was type in, Camper Solar Panel in google. If this is what you wanted please select me as the best answer.
- Q: I want to get definate instructions on how to make the components and convert my home to solar energy. I know I could hire some one to do this, but frankly I do not have the funds at my disposal to do it. I thought if I could find detailed instuctions I could slowly do it myself (with my husband's help). I have looked into loans for this purpose to no avail. Finding the information on the net could take forever! If anyone knows a site that would give me the information or even a hint on how to start? Any help will be appreciated, but if you have any good links to good information please share them with me..Thanks
- I doubt that you are going to want to learn how to dope your own silicon wafers, add contacts and laminate them into PV panels.? I also doubt that you're going to even want the various chemicals to make e.g. cadmium-based cells anywhere near your house (cadmium is a very toxic metal).? In other words, making your own solar panels is not an at-home project. You can buy solar panels based on cells of several different types.? A link to a Pricewatch-like website for current prices on solar panels is below.? Mounting panels to roofs or pole mounts, running conduit and wires, and installing battery banks and inverters are within the capabilities of skilled laypeople. More data at the links. Edit:? I am reporting all of Agua-Luna's cut-and-paste pieces as spam.? I encourage others to do likewise.
- Q: Can solar panels be installed on mountain huts or lodges?
- Yes, solar panels can be installed on mountain huts or lodges. In fact, mountainous regions with ample sunlight can be ideal locations for solar panel installations. These panels can harness the sun's energy and convert it into electricity, providing a sustainable and reliable source of power for the huts or lodges.
- Q: So I reckon it's time to install some of these bad boys. it's come to point where electricity providers are charging such extortionate amounts that I can definitely see these reaping huge rewards before long. (Okay I might be exaggerating a little - they are pretty costly themselves).The problem is I've read around that they're only fitted to south facing houses? Why so? Why can't they be installed on the rear side of the roof - the side facing the garden? My house is facing north, so the front door leads north. Could I have solar panels installed on the back? (That's basically my question, with a bit of a rant too lol).Cheers.
- You want the panels facing south because that is where they would get the most sunlight throughout the day. If your front door is facing north, then the back of your house would be facing south, right? So put them up in the back where they are facing south...haha wtf..
