EVALUATION OF SOLAR ENERGY FACILITIES AT REST AREAS IN OHIO. FINAL REPORT

Solar power, as a potential source of energy in public highway rest areas, was evaluated for Ohio. In this study two highway rest areas with solar water heating and photovoltaic, emergency lighting systems were instrumented and monitored over two years. The instrumented sites are located in the northeast and southwest regions of the State. They are two typical facilities out of 17 installations presently operating in Ohio. To evaluate performance, the solar energy system was modeled with a computer simulation and compared to actual field measurements. The computer model, adjusted for weather conditions in Ohio, is provided for any future installation design. Economic comparisons were made between solar hot water systems and conventional systems using life-cycle analysis. Results from instrumentation show that for a 20-year design life, the solar hot water systems were 9% and 22% more economical than conventional systems for the northeast and southwest sites, respectively. For the year the systems provided 52% and 72% of energy used to heat water. Solar contribution was low in the winter (4%) but almost complete (90%) in the summer.
