Performance Model
This tab activates
a highly simplified but instructive, hourbyhour solar energy
system performance simulation model called SIMPLESYS. The
development of this model is described in
Chapter 14  Modeling System Performance
PROGRAM SIMPLESYS
 This program, written in JavaScript, uses the equations and concepts
developed in Chapter 14 of this book to calculate the performance of a
highly simplified solar thermal energy system. The model is based on an
instantaneous energy balance and a simple constanttemperature control
system. Simplified analytical models of solar irradiance, collector
performance and heat loss are used so as not to hide the fundamental
energy balance at its core. The techniques used here may be refined to
any level of sophistication required by the user, in order to closer
reflect the system and location of interest. If electrical output is
desired, application of a power conversion efficiency is all that is
needed to obtain this result. To run the program, simply click on
