Solar Water Heating Project Analysis

Velimir Lackovic, MScEE


Course Outline

In addition to the energy cost savings on water heating, there are several other benefits derived from using the sun’s energy to heat water. Most solar water heaters come with an additional water tank, which feeds the conventional hot water tank. Users benefit from the larger hot water storage capacity and the reduced likelihood of running out of hot water.

Solar water heating project model have been shown in detail. The tilted irradiance calculation algorithm, the calculation of environmental variables such as sky temperature, and the collector model are common to all applications. Energy delivered by hot water systems with storage is estimated with the f-Chart method. For systems without storage, the utilisability method is used. The same method is also used to estimate the amount of energy actively collected by pool systems; pool losses and passive solar gains are estimated through a separate algorithm.

This course is suitable for engineers with a desire to understand the fundamentals of setting solar water heating project. Presented details cover issues related to technical and financial implementation and exploitation of solar water heating systems. Upon successful completion engineers will be able to address solar water heating terms, methods of operation and how to set up detailed technical and financial feasibility model.

This course includes a multiple choice quiz at the end, which is designed to enhance the understanding of the course materials.

Learning Objective

At the conclusion of this course, the student will become familiar with:

Intended Audience

This course is intended for electrical and mechanical engineers.

Benefit to Attendees

Attendee of this course will understand basic solar water heating principles and methods for sizing solar water heaters for particular application. Also attendee will be able to calculate important financial parameters that may indicate feasibility for large scale applications.

Course Introduction

Using the sun’s energy to heat water is not a new idea. More than one hundred years ago, black painted water tanks were used as simple solar water heaters in a number of countries. Solar water heating (SWH) technology has greatly improved during the past century. Today there are more than 30 million m2 of solar collectors installed around the globe. Hundreds of thousands of modern solar water heaters, are in use in countries such as China, India, Germany, Japan, Australia and Greece. In fact, in some countries the law actually requires that solar water heaters be installed with any new residential construction project (Israel for example).

Course Summary

In this course, calculations methods for typical solar water heating project were shown. The tilted irradiance calculation method, the calculation of environmental variables such as sky temperature, and the collector model are common to all applications. Energy delivered by hot water systems with storage is estimated with the f-Chart method. For systems without storage, the utilisability method is used. The same method is also used to estimate the amount of energy actively collected by pool systems. Pool losses and passive solar gains are estimated through a separate calculation method.
