Solar Water Heater Efficiency Calculator

Solar thermal water heating calculators.

Solar water heater efficiency calculator. With yield calculation based on the solar simulation programme design and simulation of a system results. 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. Base model has an efficiency that just meets the national minimum standard for gas and electric water heaters. 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.

Irradiation system yield solar fraction efficiency co savings. Solar hot water system calculator. 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 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 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. Solar energy factors range from 1 0 to 11. You ll receive a tax credit of 1 300 bringing the total cost of your system down to just 3 700.

Select the appropriate fuel type from the drop down menu. California f chart has been designed to calculate solar thermal water heating contributions for built up solar systems. 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 sef is the energy delivered by the system divided by the conventional energy input energy used by the backup heater plus any energy used to power pumps or controllers in the solar water heating system the values range from 1 to 11 with most residential systems having a water heater efficiency of 2 or 3.

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 higher the value the more energy efficient the system. 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. So let s say your solar water heater costs 5 000.

Use the solar energy factor sef and solar fraction sf to determine a solar water heater s energy efficiency. The average efficiency level and fuel cost is provided but can be changed to match your conditions.
