"Solar energy is one of the most abundant and clean energy sources of renewable energy. Due to its unsteady nature, most photovoltaic systems require a solar storage system. Ultracapacitors have proven to be an effective solar energy storage component due to their wide range of input voltages and high power density. This research focuses on characterizing the performance of a PV/UCAP hybrid storage system to meet required household loads at various locations throughout the US as a backup energy source. A calibrated empirical model was developed to characterize system performance. A load profile was designed based on a typical 2 bedroom house with 1200 square feet. Loads were varied for different weather conditions (winter and summer) and different days (work days and weekends). The main reason in considering different weather conditions and days are the use of appliances are not same on every day and the most important thing to be considered is usage of loads will be more in weekends. Similarly, the usage of the loads will be more in winter as heating loads are accounted. So, for accurate load calculations the loads are separated based on the weather and also different days. These loads were identified on an hourly basis based on the type of appliance, hours of operation and watts required during operation. In addition to regular household loads. This model was then applied to meet required loads in multiple locations throughout the United States. This process allows characterization for how the system would perform as a backup power system during various intermittent periods throughout a typical meteorological year at different locations"--Abstract, page iv.
