This article describes work on two projects of the National Energy Efficiency Program NEEP 709300036 and NEEP 271003 titled The Model of Solar Collector for Middle Temperature Conversion of Solar Radiation on Heat, and Development and Investigation on Hybrid Solar Collector for Heat and Electricity Generation, respectively. This first project deals with solar collector that transfer solar radiation in heat in area of middle temperature conversion (at temperature above 100 deg C). During entire year it can realize significant saving of electric energy used for preparation of warm water and in central and district heating. During work on the second project, two hybrid solar collectors, their installation, mathematical model, software, and experimental set-up were designed and realized. The first collector had the photovoltaic panel located above the absorber and the second collector had the panel located on the absorber. For both collectors, the results show that efficiency of fossil fuel replacement is 85%.
