During federal Fiscal Years 1982/1983, SERI research in insolation assessment concentrated on Broadband Model Development and Evaluation and Spectral Measurements and Modeling. Other efforts were curtailed because of budget reductions. The most serious impacts of the cuts were the degradation of NOAA's Solar Radiation Network and the loss of new solar radiation data. The need for high-quality data was shown by SERI's evaluation of models used to form the SOLMET and ERSATZ data bases. Comparisons of model estimates with high-quality data show mean bias errors as great as 20%. Particularly, model results were poor for cloudy conditions. Future plans may include revised SOLMET and ERSATZ data bases, using improved models and data collected from 1977 to 1980. Advances in spectral research include development of a simple spectral model (SPECTRAL) and industry development of portable spectroradiometers. SERI has used both to generate spectral irradiance standards and to study the effects of clouds, air mass, and turbidity on solar cell performance. In late FY 1983, SERI began to develop a Solar Radiation Research Laboratory which will collect baseline solar radiation data in support of all SERI research activities. It will also be the site of outdoor tests of photovoltaic devices and other solar energy equipment.
