how many 80 watt solar panels are needed to power a ranch style home?

Answer 1

Well, I have a 200 amp load center in my house. 110 volts x 200 amps = 22,000 watts (22 KW).

22,000 / 80 = 275

However, I can get by with the 7KW generator in my motorhome. So, let's say about 88.

That would still leave you enough extra most of the time to charge batteries. You would probably need a backup though in case of several days in a row in the winter of cloudy skies.

Answer 2

OK, at what voltage? An 80 watt panel would be 6-2/3 amps at 12 volts, and 2/3rds of an amp at 120 volts. A typical coffeepot is rated at aboout 1100 watts, which means about 10 amps at 110 volts (simplified math here for approximation, don't write me to correct me). A typical solar powered house uses a large storage battery with low power DC lighting and appliances suitable for battery power. The solar panels charge when the power generated exceeds the demand. Simple in theory, difficult in practice. The charger for the battery to maintain it in good health is very expensive. The battery is also very expensive. Think deep cycle car batteries but several orders of magnitude bigger and also comparatively expensive. I know a guy on the Olympic Penninsula who went off the grid expecting Y2K to be the end of the world. He spent over $30,000 on the equipment. He'll never recoup the expense. OH, and another thing, for some things, you will still need AC power. He had an inverter which converted the 24 volt DC from the battery to 110 AC, another very expensive item. His battery is rated at 24 volts and 500 ampere-hours (I think). That's a lot of battery. With proper care, his cells should have a life of 10 years or more. I think he has 2000 watts of solar panels at 24 volts which gives him a no-load charge current of 80 amps in noonday bright sun in the summer, less on the winter solstice since we're so far north. I am not sure I remember the numbers as this was 8 years ago when I was helping him assemble the parts and such.

There really is no way to easily equate the 110 volt AC house to a solar powered house because the electrical equipment is quite different, sort of like apples and oranges.

Answer 3

Your other answerers are being too complicated. The adverage house uses 1 kilowatt of ac power once the day is adveraged out with loads that can reach 3 or 4 kilowatts some hours. Solar panels produce dc power that has to be converted to AC to work with you normal household grid. To make this work you need an inverter. Inverters use around 40% of the power. So you will need about 1.4 kilowatts from panels.

Now that the very large generalalities are out of the way, understand that you get buy with a lot less dependant on your usage. In addition most people use it to supplement their power, which is much better route to go.

Answer 4

you may run an mind-blowing form of issues. in case you placed the gadget to cost batteries once you at the instant are not making use of something, they're going to value effectively. you need to use the gadget for lighting fixtures, LED lighting fixtures direct from the battery ability is maximum effient because LEDs are low voltage gadgets with an exceedingly long life span. I replaced a 2 tube flourescent trough with 4 5Watt PowerLEDs working example, at an identical time as I truly have it on 120VAC on the 2nd, i will circulate it to twelve VDC ability comfortably, and had set it as much as run initially on 12 volt components. There are additionally many 12 volt home equipment as nicely. it is likewise possible to transform a number of those "multi function" stereo structures to function on 12 volts by removing the flexibility furnish. you will truly use much less ability by doing so. you heavily isn't waiting to blow the shingles off the roof till you upload a classification D amplifier to the output, yet for many listening, the output is sufficient. some small television's at present could be run from 12 volt components, if no longer straight away, then with a buckboost inverter for a working laptop or computing device. The small TVs in basic terms draw approximately 30 to 40 5 Watts. pass the belief of making use of an inverter, they do no longer look to be effective at small plenty, and represent added load on the gadget. So with a touch making plans, you may run plenty from that 60 Watt gadget. you may a minimum of take some chew out of the electrical powered bill for mundane lighting fixtures. you additionally can use them to maintain ability up on a battery gadget for lighting fixtures in a distant barn. The makes use of are in basic terms constrained by your mind's eye and creativity.

Answer 5

100 of them plus a bank of storage batteries would allow you to use power without having to worry about the load very often. Our household has a 8KW cut-out to reduce our supply charges, and it hardly ever cuts out. Of course, most of the time our consumption is way below 8 KW. An average household has an average consumption of 2 or 3 KW.

Answer 7

It depends on the power consumption of the home,
the outside temperature and the homes insulation..

Cmon hippi... Need lot's more info then just that.
