Q: Can solar panels be used in combination with other renewable energy sources?
Yes, solar panels can indeed be used in combination with other renewable energy sources. Many renewable energy systems today incorporate a mix of solar panels, wind turbines, hydropower, and geothermal energy to maximize efficiency and ensure a reliable and sustainable power supply. This combination of different renewable sources allows for a more balanced and consistent energy generation, reducing reliance on a single source and increasing overall system resilience.
Q: I am trying to built a circuit that will power two USB ports (both 5V and 0.5 amps) from the output of a solar panel that produces 20V at 0.2 amps. I have a voltage regulator that runs at 5v and 0.5 amps but I can't figure out the best way to boost the current up to 0.5 amps before I incorporate the voltage regulators.
The previous answer about wattage is correct, so this is your first problem. Try increasing the number of solar panels by connecting them in parallel. To answer your question about increasing current, a voltage regulator wastes energy to regulate voltage. You need somthing that is not so wasteful, and that is a DC-DC converter. You will need to buy a 20V-5V model. this will give you less voltage but more current than you origionally had with your solar panel. You can alter voltage and current capacity, but you cant increase power (watts) with a DC-DC converter.
Q: Can solar panels be used on boats or RVs?
Yes, solar panels can be used on boats or RVs. In fact, they are a popular choice for these applications as they provide a reliable and environmentally-friendly source of power. Solar panels can help to generate electricity for various onboard systems, such as lighting, appliances, and charging batteries, making them an excellent option for those seeking off-grid power solutions while on the move.
Q: I would like to know of any construction companies, road crews, or any company that uses solar panels in the Tampa area and throws them away. I like to recycle solar panels by repairing and processing what power I can from them. Know any companies that throw out used solar panels? If so, can you provide the name and number?
When you pass a sign- look at the back of it for a name. Often the company that rented them out will have their name on the back. Call them.
Q: I contend:As far as the solar panels causing global warming I'll try to explain. 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). The net heat gain is zero. 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 result is a net gain in earth's temperature.Right or wrong?
As far as it goes, you're right: putting up a big black object increases the total amount of energy absorbed from the sun. But that's only part of the story. If you didn't put up the solar panel, the same radiation would hit the earth. The earth already absorbs 2/3 or so of the energy that comes in (albedo .30), so adding even a perfectly black object increases it only by 50%. But it's not even that much, because most of the extra energy absorbed is converted into electricity. Solar panels are about 0-5% efficient, so half of the extra energy is turned into electricity rather than heat. Eventually it's put to use and turned into heat, but that heat was going to come from somewhere else anyway. (Even if it's just powering your DVD player, it turns into heat just the same as if you were using it to heat your house.) If you dig up a gallon of petroleum or fission a microgram of uranium, that's heat introduced into the earth's atmosphere. And these processes are inefficient: between generation and transmission you lose about 75% of the energy, meaning you've introduced 4 times as much energy into the atmosphere as you've actually used. So with a solar panel, you add extra heat to the earth by about 25% of incoming solar radiation, but you've offset external costs by about 45% of incoming solar radiation. The net effect is to cool the earth. And that assumes that the solar panel itself is perfectly black, which isn't the case. Real commercial solar panels have an albedo of about .35, which makes them more reflective than dirt and considerably more reflective than asphalt shingles, which have .03 albedo. In other words, even if you didn't actually use the solar panels for electricity, they'd be cooling the earth just by reflecting energy back into space more than your regular shingles.
Q: I've been reading up on Solar panels because I think in the long run this would be beneficial in the long run. My Dad had looked into it before passing and had said it was too expensive. How much does it range for getting them placed on the roof and how exactly does that work? I think I remember being told that PGE has incentives and could possibly even end up paying you for having it? What does having panels cover? I know electricity but does it also heat things up? Sorry I'm kinda dee dee dee on this lol. Any and all information would be greatly appreciated. If anyone has solar panels can I get your experiences with them? Thanks!!
There's a few different kinds of solar panels. Some of them are only for collecting heat, they're relatively inexpensive and not a bad deal, though installation can be expensive of course. The most sophisticated of these use some pretty high tech collectors to heat up an antifreeze solution that in turn is circulated through a reservoir (how water heater), to supply the house. Your electric producing solar panels are more expensive. You can go on OKorder and do a search on photovoltaic panels and get a pretty good idea real quick. The panels alone can run you 2 or 3 bucks a watt of output or more, and you may need 3 or 4 thousand watts of output to give you reasonable system for your house, depending on how much electricity you use. Then there's installation, for which you may need a professional electrician and so on. If you want a system incorporating deep cycle batteries then that's another expense, but you don't necessarily need those if you're not planning to take yourself completely off the grid. Not that the systems are really complicated. Some people wire panels together themselves from scrap cell components to save money. Of course you'd need to understand the basic wiring involved for that, and you'd almost certainly be required to retain an electrician to tie any system into the grid itself. Although there is such a thing as a plug in grid tie inverter. This is is a gadget that will take your DC solar panel output and feed it into the standard wiring of your house via an ordinary electrical outlet. You'd still need to understand enough to get the DC voltage right no doubt.
Q: Any opinion on harbor freight solar panels ?
Actually, if you are looking to start slow and inexpensive, they are an economical way to get your feet wet, so to speak. I also tried the make them yourself kits, where you get a stack of cells, a frame and solder and you have to get the glass and assemble it yourself. I combined the Harbor Freight kit with one of those panels. Problems you will run into start with the kit having no inverter and not much information on any kind of power storage, you get to work that out for yourself. I initially wired them to provide all the power for the ceiling mounted lights in a small house, on a totally independent circuit, using 3 car batteries for storage. It worked perfectly, however the code inspector I got from the City could NOT fathom that my system had no connection whatsoever to his grid and would not pass it, even though I showed him the separate breaker box that was not supplied by the line coming into the house for the rest of the power. I finally gave up on him and put the lights back into the main system and use the solar setup to charge cell phones and occasionally power a lamp, as the inverter has plugs right on it. It keeps those car batteries fully charged going on 4 years now, with no issues detected at all.
Q: For example, how many large solar panels would you need to operate a greenhouse with lighting for simulate sun during cloudy weather, a scheduled sprinkle system and other such things?I'm looking for a very in depth answer.
if you are talking electrical solar panels, they are rated in watts they generate in full sun. usually these panels are used in tandem with batteries, so they charge up during the day and the batteries hold a reserve of power for later use. If you figure 8 hours of useful sunlight per day, then a 40 watt panel will light a 40 watt bulb for 8 hours. you can also measure capacity in watt-hours. this would be 40x8 = 320 watt-hours. the general method is to determine how much electricity demand you have over a 24 hour period to get the total watt-hours. then divide that by the watt-hour capacity of one panel to get the number of panels needed.
Q: I've heard that solar panels have back-up batteries for when it is cloudy or rainy that day.. is this true?
There okorder / Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q: Can solar panels be damaged by hail or strong winds?
Yes, solar panels can be damaged by hail or strong winds. Hailstones can cause cracks or fractures in the glass surface of the panels, affecting their efficiency. Additionally, strong winds can potentially dislodge or break the panels if they are not properly installed or secured.
