The systems have been extensively instrumented; data are col 1ected each mi nute, averaged over ten mi nutes, and recorded on magnetic tape. The averages are collected via teleph one and archived. The analyses described here were based on averages obtained from four flat-plate systems. The two objectives of the study were (1) to develop equations that could be used to predict future performance and (2) to determine if system degradation were occurring. Equations for power, cell temperature, and de efficiency were developed using linear regression techniques. The results indicate that system power and cell temperature can be determined as a 1inear r e1 at i onship of climatic conditions. However, efficiency cannot be modeled as a linear function.
