DELSOL is a performance and design code that includes optical and economic analyses. An analytical Hermite polynomial expansion/convolution-of-moments method is used to predict flux images from the heliostats in a computationally efficient manner (typically much faster than either MIRVAL or HELIOS). The code accounts for variations in insolation, cosine forshortening, shadowing and blocking, and spillage, along with atmospheric attenuation, mirror and receiver reflectivity, receiver radiation and convection, and piping losses. The code can be used to evaluate the system levelized energy cost and optimize the field layout, receiver dimensions, and tower height based on these costs. The code is written in FORTRAN77, and input to the code is entered via user-specified text files.

SOLERGY simulates the operation and annual power output of a solar thermal power plant. It utilizes actual or simulated weather data at time intervals as short as 3 minutes and calculates the net electrical energy output including parasitic power requirements over a 24-hour day. Factors include energy losses in each component of the system, delays incurred during start-up, weather conditions, storage strategies, and power limitations for each component. The original version of SOLERGY (Stoddard et al., 1987) required that the energy collected by the receiver subsystem be sent to thermal storage. The code was later modified to allow the collected energy to bypass storage for analysis of the Solar One power plant (Alpert and Kolb, 1988). The code is written in FORTRAN77, and input to the code is entered via user-specified text files.
