        Q: How do I figure out how many solar panels are needed for off grid solar system?
A: First of all , Running a washer and Dryer would be needed a very huge system alone . Electric stove 's also presumably out of question .  Most people have an unreal expectaion of a ordinary Solar system . One panel ( About 3X5 ft. ) solely can supply about 7ty Watts of power for 6-eight hours on a pleasant sunny day . One panel is costingbout $ 400 dollars was later you also will spend various $ thousands for your Inverter / comptroller . One panel will supply sufficient power for possibly 1-2 lighting bulbs . Each panel will solely provide around 500 Watt-Hours a day on a sunny day .  An average electrical home may use like 50 Kilowatt-Hours per day . That is 50,000 Watt-Hours . It would take 100 Panels . This pretty system would were extremely costly and impracticle for the majority users .  If you wish to go completly solar , you are required forget driers , frost free frig , electricalal heating , Air conditioning , Pumps or any other huge electric loads .  I help my friends work on their systems . It is a community that has no grid power . Everythe first is totallies independant . Most have 12-16 panels , an enormous bank of batteries , including at least a 10KW Generator . These systems cost $ 35,000- $ 40,000 , and still were not able provide any heating or air conditioners without running the generator .  If you wish to assist the environment , just buy what panels and inverter you are able afford , and complementing your power needs , unless you 're ready to drastically change lifestyle when you go completely solar .   Another choice is to get your system free from somebody like the connection below . Here you just paying off the power it produces and be ensured for something like twenty-five years the rate will not change . 

Q: How many solar panels do you need to power a house?
A: Hey Martin , Shane is also possible closes on the number , however , it is all just a guess without learn more about your house and your weather . You see , asking an issue like yours is no various than asking , `` How much gas does it take to run a automobile ? '' It depending on the automobile , the miles it is driven , driving habits , and therefore on . We have a home in the Northern Great Lakes that is absolutely powered by the wind and sun . The solar array 's our primary power source , probably delivering about 80 per cent of our needs , more during the summer . Although our house is little , about one200 squares feet , and relatively efficient , our array fits nicely on the roof of our single automobile carport , perhaps taking up 180 squares feet , nothing roughly the sized of a football field . All of our equipment costs just under $ 15,000 , including such batteries . Todays , if you are able benefiting from net meter in your region - why did n't you need batteries or charging controllers , but you do need utility power . The grid becomes your battery in the present agreement . The only drawback is if the electricity grid goes down for any reason , you solar array goes with it . So you might find yourself in a position where the sun is out , and you do not have accessing to the power in your own solar array . This is feasible to frustrating to new proprietor .   My bestest suggestion is you get a subscription to Home Power Magazine , these people are the only periodical that get into the nuts and bolts of what you 're asking about . There be a few good websites as well , I will list a few below . Do n't be losing your time asking hacks like me online for info , you get answers like football the areas and barrels of money which distort the actual facts . You can reading about people who have done exactly what you 're was endeavouring to do in the magazine articles , verify out providers websites that advertise there and learn an enormous dealing . In the end , you might decide not to get embroiled , and that is fine , but at the very least you will are very well notified .   If you are a handy type and can do certain basic wiring , I would propose you 're starting to by obtaining one panel , are a few golf cart batteries and thereforeme DC breakers and switches and set up your own twelve volt power system . We did 12 years ago , even put twelve volt outlets in all the room . They still work today and are still to be handy for little electronic and lights . If you subscribe to Home Power , you are able go online to their website and look up archive articles from years past . Our house 's even features in one some while ago . Use their searching engine to look up , `` Starting Small First , '' if you wish to see it . I would also suggest going to an energy fair if you are truly interested after looking all this up , these people are enumerated in the magazine as well .   For comparison purposes , I will give you the specs on our homes system you were asking about above . This is the equipment necessary to run our home , with a small assistance from the utility company . Our electrical bills average just under $ 5 a month .

Q: How many solar panels do I need to have 5000 kwh per month?
A: `` Everyday I use 11,280 kWh ``  11280 kW-hour / 24 hours = 470 kW  WOW , that is a extremely high power level , most houses use an averaging of 1.2 kW .   My guess is that you means you use 11280 kW-hour in per year , which comes to an average power of 1.3 kW , characteristic .   Assuming you get , worse case , 6 hours of sun a day , for the firstly case , 470 kW , each solar panel generated by the is equal to 250 x6/24 = 60 watt , so you would require 470k/60 = 8000 panels   For the second case , 1.3 kw or 1300 watt , divided by 60 that is around 20 panels . Depconcluded on wherever you live , you could need as much as twice that numbers .   Plus you need charge comptroller , a lot of costly batteries , and an inverter .   The great problems is periods of no sun . If you demand constant power , and you have a period of , say , 20-4 hours without any sun because of storms , etc was later the numbers of batteries risen to the hundreds .
