- Q: I have a cabin that is way out in the middle of no where, it would cost 000's of dollars to get power to it. If I have a 8,000 BTU air conditioner that runs on 25 volts and 5 amps (or 875 watts)How many solar panels will I need to run this during the day, plus charge the batteries to run it all night? How many batteries would I need
- Unless you have a good charge controller, the battery will never charge, as a lead acid battery requires 5 volts to charge. Ans you don't tell us the capacity of the battery? Is the solar cell only 5 watts? That is amp if it develops 5 volts. Assuming the solar panel is good for 5 watts and 5 volts, that is only amp. so you are charging the battery with amp and discharging it with 5 amps, so how long you can do that depends on the size of the battery. But it will discharge in at most 5 hours with a large battery, and the solar panel will take several days to charge it up again at amp. The best you will be able to do with that 5 amp load is perhaps hour a day, which is 2 watt-hours. The solar panel will be able put back amp for 2 hours at 5 volts, which is 5 watt-hours, which will give you perhaps 2 watt-hours in the battery. .
- Q: Can solar panels be recycled? What about the manufacturing of these panels is it done in an Eco-friendly way?
- All kidding aside, you will possibly desire to do not forget that the White abode is the suited representation of the u . s . to the worldwide. because of fact of this that's equipped so vast and ambitious, and ambitious. image voltaic panels and wind generators will tutor a destructive connotation, form of like antennas on a boarding abode with wires putting down ought to characterize a ghetto to the castles and empires of the worldwide. there is likewise the reason for uninterrupted electricity throughout the time of an attack on the capital, it continues to be a area of the regulations of conflict you recognize. including option potential sources might supply a splash as to how the device works, or no remember if it somewhat is not that way, might come throughout the time of as being hypocritical, or purely for tutor (Like that's not being achieved now...)
- Q: discription how does solar panels save energy
- Solar panels don't save energy, they just utilize a different source of energy. To the extent that it replaces energy from sources which are limited themselves (such as fossil fuels), solar energy does save those resources.* The main benefits of solar energy are environmental in the sense that it is nonpolluting,* but using solar energy doesn't reduce actual power consumption. *Excludes environmental costs of producing the solar panels themselves, but these are much smaller than the environmental benefits of solar vs. fossil fuel (which has infrastructure costs of its own).
- Q: Online stores selling solar photo-voltaic generation kits gives specs indicating the power generation capability of the system. For example, Solar World Grid-Tie Solar Electric System with 245W Panels PV Powered PVP2000 Inverter, .2 to 2.4 kW. This seems to indicate that the system can generate .2 to 2.4 kW. Is that per day? Per month? I'm trying to calculate the return on investment, but can't because I don't know how much power a system such as this will generate in a month.
- As Ed said, that .2 kW is an instantaneous rating in bright sun. The way to do this right is to consult the maps here rredc.nrel /solar/old_data/nsr... to find the number of equivalent sun-hours your location gets per day. Select, Average, Annual, Flat plate tilted south at latitude. A map will come up. For northern California, it shows 5 equivalent sun hours per day, for example. If the system is .2 kW, then .2 x 5 = 6.0 kWh of energy the system will generate per day, on average. That takes into account cloudy days, short winter days, long summer days, everything. The 2.4 kW system would give double that, obviously. But that's an example, based on a specific location. Phoenix would do better, Seattle would do worse.
- Q: Can solar panels be installed on a sloped roof?
- Yes, solar panels can be installed on a sloped roof. In fact, many residential and commercial buildings with sloped roofs have successfully installed solar panels to generate renewable energy. The angle of the slope can affect the efficiency of the panels, but with proper installation and positioning, solar panels can still effectively harness sunlight and produce electricity.
- Q: I'm a student trying to design a mounting structure for solar panels. I'm reading about passive trackers so as to track the sun for optimal energy production; but I am not fully quot;seeinghow it works. Can someone please help explain it to me, or at least send me a link(s) that could help explain it well?THANKS IN ADVANCED!! [and HAPPY HALLOWEEN!!]
- It appears to be relying upon a phase change of liquid to gas to liquid to balance the system and return it to the east in the morning.
- Q: i don't know very much about it, but can you somehow take off the little solar panels off of the outdoor light things and make it so you can hook an outlet up to it and plug in to it like a phone charger for electricity.
- Little solar panels on lights are very low power. The battery in one such may be 0.5 Amp-hours and .2 V ; it may be different but it should be marked on the panel/battery/manual. An outlet in your house is designed to run on 20 V (typically in N. Am.) and they run on alternating current (AC) whereas the panel generates direct current (DC). (If you don't know the difference, do not worry to much but just understand that they are not directly compatible.) You therefore need an inverter to change DC to AC (and lose some although inverters are now very efficient). But the amount of power generated by those panels is still very small. That is why solar lights are low power (just a few watts in most cases). To make things even more irritating, phone chargers do not work off 20 V AC as you are charging the battery and need a low voltage DC -- which is what the solar panel is giving you. It is almost certain that the voltage from the panel will be less than the voltage required for the phone. The charger is mostly cable but there is a black box incorporated and it should say what the voltage and current output are (the input will be 20V). So you should be able to overcome this not by hooking up the panel to a 20V outlet and then plugging the charger in but by hooking up the panel to the phone directly if you can get enough voltage out of the solar panel (or hook up several) and if you fashion a connection device. They already make them -- solar battery chargers and I am sure you can enter that into a search engine and find loads. Typically the panel alone is much more than a solar light -- which shows the relative power requirements.
- Q: Can solar panels be used to power an entire office building?
- Yes, solar panels can be used to power an entire office building. With proper planning and installation, a sufficient number of solar panels can generate enough electricity to meet the energy needs of an office building throughout the day. This can significantly reduce or even eliminate the reliance on traditional energy sources, leading to cost savings and environmental benefits.
- Q: I'm looking for some advice on hot water solar panels. I'm trying to save some money on electricity. A neighbor has been suggesting solar powered equipment for some time now, and I think he's right. It does save quite a bit of money in the long run. They're kind of expensive though, so I'm looking for cheaper alternatives.
- If you are just looking for hot water, you can build your own water pre-heater with copper tubing, mirrors, black engine paint, wood for an enclosure, and glass to cover the enclosure. I have seen plans online but cannot recall just now where. I've included some links below that you might want to check out. Also, you may want to check on tax rebates in your area for using solar. In some areas you can get rebates to pay nearly 00% of the cost. Or search for how to build a solar water heater for a LOT of online sites. One caution, do NOT use water directly from a solar water heater as it can be hot enough to burn your skin.
- 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!
