Payback time in solar water heater varies. Depending on the family size, the number of consumers who use it in one household. But typically, a 3 year payback with rebates, others may feel of about 5.5 years. For more info, you may visit this site sunbelt-solar.com/ cost.html

It depends how much you pay for it ,here's the thing about solar water heaters .it only cost about $10 a month to heat the water with electricity. but you have hot water any time you want it .solar water heater only works when the sun is up ,so no hot water when you get up in the morning .not till 9 am or so it is only good if you need hot water in the middle of the day

It depends on how much hot water you use. The most efficient use of one is to have solar heater, heat water that is then supplied to hot water heater. If water is hot when it enters the hot water heater it will only use power to keep it hot.

This will vary with the cost of the system. The efficency of the system. The amout of water you will heat vs the amout of water you heated before. The cost per btu (energy cost) of your water heating device you use now, and the future cost of energy if you decide not to swap over. (future cost + increase energy cost) Some of these equations will have to have a swag answer. You probably have not measured the exact cost of energy per gallon of water with your existing system. You probably don't know how much water you actually use. With out these data points, its hard to have a starting point to build an equation. Can you get an accurate measurment of the number of sunlight hours you will have for the next 3 or 4 years or is this going to be based on the last 50 years of data.

If your house is all electric, a standard-electric water heater is about one third of your power bill. An average water heater is rated at 4500 Watts (4.5KW), and uses 4.5 KW for every hour it is in operation. An average home, 3-4 people, uses between 50-75 gallons of hot water per day. The above mentioned water heater will be on for 3-4 hours per day. This equates to about 15 KW used, or 15 KWhrs, every day. If you pay 10 cents per KWhr, this means you're spending about $1.50 per day to heat hot water, or about $45.00 per month. A solar water heater obviously uses the sun to heat the water, which is a free heat resource. When water usage patterns, such as showering/ bathing, and doing laundry are changed to allow for water usage during the daytime, the solar panels will be doing the majority of the heating. On average, this reduces the amount of electricity used by the water heater by about 70%. If you take $45.00 and multiply that by 0.7 (7%), you have your average energy savings. For an average home, this comes out to just over $30.00 per month, or $360.00 per year. If you divide what it's going to cost you to install the system by the annual savings, you'll have your payback time.

Payback time averages between 5 and 10 years just check out efficiency ratings on the internet for various systems
