How to calculate the estimated cost and energy efficiency of a Solar Hot Water H - Adelaide

Today, a majority of Australians are using solar hot water heaters to meet their hot water needs. Why not, as his hot water heater is more energy-efficient, saves electricity bills, and is also environmentally friendly. However, it is also true that its original price is quite high and installation charges are not for everyone's budget.

How much money you save on solar heater depends on the following factors:

•Your requirement for water
•Performance of the system
•Geographical location and solar resource
•Available financing and incentives
•The rate of conventional fuels that your water heater would otherwise use.

Once installed, it is estimated that your solar water heater bills can tend to drop by 60 %. And, with the sun as your source of fuel, you will hardly face fuel shortages or price hikes in the future. If you are constructing a new home or going for refinancing, the scale of economies is itself attractive, and that includes the price of a solar water heater across a 30-year mortgage that amounts to between $13 and $ 20 per month. Tax deductions for mortgage interest attributable to solar systems reduce that by about $3 to $5 per month. If you save more than $15 per month on your fuel, the solar investment is immediately profitable. On a monthly basis, you're saving more than you're paying.

Finding the energy efficiency of a solar water heater

You can also utilize the solar energy factor (SEF)and solar fraction (SF) to determine how much is the solar hot water heater's energy efficiency. The solar energy factor is calculated as the solar energy delivered by the system divided by the electrical or gas energy input. The higher the number, the more energy efficient the system is. There are 11 solar energy factors. Systems with solar energy factors of 2 or 3 are in popularity list.
