	Summary:		Summary:
	*Total: $1730/yr.		*Total: $1730/yr savings for 2 people if we go electric. For a facility of 24, we may save $15k easily in energy saving mode (50kW system extrapolation) - if 50kW solar is sufficient to run the entire facility. That would be under very efficient operation.
	*How does it compare? $1692 for lowest below - so OSE ~~does~~ the lowest average.		*How does it compare? $1692 for lowest below - so OSE saves in practice as the lowest average from statistics.

	*Note [[Solar Calculations]] imply average capture is 1/6 of the installed peak kilowatt - 4 kWhr/day instead of 24 kWhr/day if the sun were shining 24 hrs per day.		*Note [[Solar Calculations]] imply average capture is 1/6 of the installed peak kilowatt - 4 kWhr/day instead of 24 kWhr/day if the sun were shining 24 hrs per day.

	Perhaps the large 80 gal heater is the way to go as a basic, off-the-shelf unit running on solar. Keep it on only during the hottest sun time. Heat loss of a hot water heater is 1-2.5 kWhr/day - [https://www.viessmann.co.uk/heating-advice/how-long-does-water-stay-hot-in-tank#:~:text=As%20an%20estimate%2C%20the%20water,form%20of%20insulation%20you%20have.]. This means that if it took 4 hours to heat the 80 gallon tank at 9kW - then it took 36kWhr, so daily loss of 2.5 kWhr means it would take 14 days for all heat to be lost? That means, we lost 1/14 50F = 3.5F per day? If we went to 110F, then after 3 days we are still at about 100F!

	'''Summary:''' Grid connection costs are $10k and up, which is thus a budget for going off-grid and not paying any more.

'''Summary:''' Grid connection costs are $10k and up, which is thus a budget for going off-grid and not paying any more. If lifetime cost is considered, you will save $150 for gas/electric, $47 for water per month. About $200/mo or $2400/yr. Avg from govt is $2060/year on utilities, but that includes internet/phone/trash - so the govt average is much lower. Even if we take that - an average household will save 78*2k=$160k on utilities, or $64k on utility bills.
