Solar Water Heater Efficiency Calculator

So let s say your solar water heater costs 5 000.

Solar water heater efficiency calculator.

Use the solar energy factor sef and solar fraction sf to determine a solar water heater s energy efficiency. The solar fraction generated is based on compliance with the 2013 title 24 building energy efficiency standards and should not be used for any other purpose. The objective of using a solar thermal calculator is to determine the size cost and eventual cost savings of the solar thermal system you will need based on your hot water requirements and access to the sun. The solar energy factor is defined as the energy delivered by the system divided by the electrical or gas energy put into the system.

The solar fraction generated are based on compliance with the building energy efficiency standards and should not be used for any other purpose. The higher the number the more energy efficient. The higher the value the more energy efficient the system. Base model has an efficiency that just meets the national minimum standard for gas and electric water heaters.

Select the appropriate fuel type from the drop down menu. You ll receive a tax credit of 1 300 bringing the total cost of your system down to just 3 700. Future electricity price trends and a discount rate of 3 2 are based on federal guidelines. Annual energy and cost savings are calculated based on the current hot water heater fuel type fuel price and water heater efficiency level.

Solar water heating calculation for built up system the title 24 solar water heating calculator is designed to calculate solar thermal water heating contributions for built up solar systems. Lifetime energy cost is the sum of the discounted value of the annual energy costs based on assumed water heater life of 13 years. The investment tax credit also known as the federal solar tax credit offers a credit equal to 26 of the costs of installing a solar water heater. Solar hot water system calculator.

Solar energy factors range from 1 0 to 11. For calculations of hot water requirement and sizing of solar water heater system a software was designed in india to help any resident to calculate their solar water heating system needs. The average efficiency level and fuel cost is provided but can be changed to match your conditions. The calculator at present is designed to calculate the approximate size of the collector and the storage tank of a solar system for individual residential.

California f chart has been designed to calculate solar thermal water heating contributions for built up solar systems. With yield calculation based on the solar simulation programme design and simulation of a system results.
