Q:Can someone tell me if I can run a air conditioner off solar panel?I have a ET-P65420 20Wp solar panel. What do I need to make it work? I am told I will need a Enphase Energy Microinverter M20. Is that true? I am looking to run a 5000 to 8000btu air conditioner to a max of 0000btu air conditioner. I need to cool a 0x30 space. One time I read, I need total watts of panel to match total watts of air conditioner. Then I read, that I do not and can run more watts then what the panel is depending on the inverter and batteries.Can someone tell me what and how to make this work please? More panes or inverter and batteries?: Solar Panels Air Conditioner

Q:I recently bought a house with very old solar panels (about 25 years old) that don't appear to work properly. They are supposed to heat the hot water heater but they don't always work, and recently have staretd leaking. So, I have had them turned off and now we're just using electricity to heat the hot water. My question is, is there any tax credit money (stimulus or otherwise) available for people to (a) repair old solar panels or (b) replace them with new ones? How does the credit work?: Congratulations okorder /

Q:Is there any way to charge my laptop with a solar panel? Is there any panel like that. Or if I work on panels can I do something like that. If you know anything about it, can you just help me? Thanks a lot.: A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.

Q:I want to install solar panels in my roof and most installers don't recommend any particular brand. Do you have experience with any particular brand that has worked for you or anybody you know? Does the brand of the panel make a difference?: You don't say what you are doing. Are you trying to get electricity from them and need solar photovoltaic panels or are you trying to run a heating or hot water system and need solar thermal panels. It is unfortunate that both of these are known as solar panels as they are really two entirely different designs. Currently the solar thermal panels are more efficient and therefore have a quicker pay back period usually measured in lower single digit years while the photovoltaic panels have paybacks that are sometimes more than double that unless you figure in increased property values and state and federal subsidiaries and tax credits where available. Edit: Recent advances make any current investment in photovoltaic panels likely to be obsolete in 5 years. Still someone has to be on the cutting edge. Two currently available technologies are concentrating the sun's rays within the collector on a much small chip area.2 This improves the efficiency and lowers the cost as concentrators are cheaper than chips. The other option is newer chips that accept a wider spectrum of solar energy.3 This has the potential advantage of producing more energy on cloudy days. This may not be so important in your situation. Balanced against cutting edge technology will be the possibility of getting older panels at a less expensive cost. The bottem line will always be pay back period. More panels at a lower efficiency and cheaper price will be just as good as high efficiency at a higher price if the numbers work out. 4 Between two answers here you now have a criteria for selection and some recomendations. Good luck with your project.

Q:I have tried researching on the internet and just cant find any real answer. I know that the amount of electricity produced when taking in the suns rays depends on the placement of the solar panels but I am just looking for ball park figures. Thanks: Ultimately it depends on your utility and the country you're in. In countries like Germany, Spain and the UK, the utilities will pay a higher price for the power you produce then what they sell it to you at. Otherwise, in countries that don't have such arrangements, net metering is best where what you produce is discounted from the amount you buy per month therefore so long as you produce less than you use, you get the full retail rate, otherwise you may get only half the retail rate with some utilities. Obviously, the solar panels are rated and won't produce much more than the rated power, a 4 foot by 2 foot panel would usually be rated at 00 watts but in most situations will produce about 80 watts and would probably cost about $500 US installed. If you assume 8 hours of usable sunshine a day, 70% sunny days, a 25 year service life, monthly billing and 0 cents a kilo watt hour retail rate, you can expect at most a -.67% per annum return on your investment, that's a negative sign out front. Basically without any subsidies, you will lose money on the panel, sure you're get some money every month, about $.34 per month for that 00 watt panel but it won't make back it's money at at a rate of 0.0 per kwh. With subsidies it might be a good investment but it's still not a good deal without subsidies.

Q:Do solar panels require regular maintenance?: Yes, solar panels generally require regular maintenance to ensure optimal performance and longevity. This includes periodic cleaning to remove dirt, debris, and snow, as well as checking for any possible damage or malfunctioning components. Additionally, regular inspections and maintenance by professionals are recommended to identify and address any potential issues or inefficiencies.

Q:Hi, wanting to set up the most basic solar panel system for a cabin in the woods that has enough power to recharge four 2V car batteries during the daytime (i am assuming; we want to run a mini fridge maybe a stove and a few lights at night off the batteries and be able to run it all just off solar during the day) It also needs to be able to power some simple tools during the day... Experience would be absolutely amazing since alot of the info on solar paneling is either really dumbed down, or ridiculously confusing.As of right now I am looking at a 3 panel (45watt in all) solar kit that needs a 300w inverter.... is this sufficient for my power needs? I am just a little perplexed, thanks so much!: ever looked at the light from a 45 watt bulb? it's true that in a cabin, if you're in the right place, you can read from it. however, assuming that you get 6 hours of sun, you can run your light for 4-5 hours. and nothing else. if you're hoping to run a stove, you're going to need several hundred watts. not sure what tools you're thinking of, but i don't know of many that run on 2v DC. (not sure that i know of a stove that runs on 2v DC either, but you can look that up.) for tools, you might want to consider a gas powered compressor and air tools. that'll give you the strength that you need. yes, i know that's not what you were thinking, but pretty obviously you're going to need to do a bit more thinking. even a minifrig is going to use considerably more than 45 watts. and that would be 24 hours a day. remember, a minifrig has considerably less insulation. you can't save much and per pound, it takes more juice.

Q:i'm making a small solar panel powered fan but it cant run the cellphone vibration motor even i have place two x2 solar panel.: Did okorder / . Possibly this could immediately instruct each and every one!

Q:Can solar panels be installed on a rented property?: Yes, solar panels can be installed on a rented property, but it would require the permission of the property owner. It is recommended to discuss the installation with the landlord and reach an agreement on the terms and conditions before proceeding.

Q:I am completely ignorant on this subject. I was just wondering out of curiosity of how many solar panels and equipment that it would take to run a central ac for a 2500 sq ft home and a pump for a medium sized pool. I'm talking running ac for like 8 hours a day to keep around 65-70 degrees and running the pump 24/7. Just looking for a general ballpark answer.: Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.
