[IEEE 2019 IEEE Global Humanitarian Technology Conference (GHTC) - Seattle, WA, USA (2019.10.17-2019.10.20)] 2019 IEEE Global Humanitarian Technology Conference (GHTC) - Analysis of Field Collected Data for a Prototype Photovoltaic System in Nauta, Peru
摘要： This paper describes the field collected data from a prototype photovoltaic power system at the home of the director of JungleMaster Ministries in Nauta, Peru. The system was designed and installed by a team from George Fox University in the summer of 2017. After almost two years of daily usage, the data was used to analyze the current health and functionality of the installation. Additionally, an unexpected issue with the loads and batteries is discussed, with possible causes and potential solutions.

Design of a Photovoltaic System with Ultracapacitor Energy Buffer
摘要： Global concerns over the damage caused to the environment by fossil fuels, as well as the instability of oil prices, has led to an increase interest in alternate electric power generation from renewable sources such as the sun, wind and geothermal energy. Solar energy is produced by solar panels which are made of materials having the capacity to create a flow of electric carriers when exposed to the solar irradiance. The efficiency of these panels depends on the sun light, and they cannot work at their maximum power point independently, hence, requiring Maximum Power Point Tracker (MPPT). This MPPT permits to compensate the changes in irradiance and temperature conditions and variations in load demands which cause power imbalances. As such, a photovoltaic system with supercapacitor energy buffer is designed using Psim software. The system consists of a photovoltaic array, a MPPT, a supercapacitor, and a charge controller which is to effectively balance and regulate power in the system.

[IEEE 2018 International Conference on Information , Communication, Engineering and Technology (ICICET) - Pune, India (2018.8.29-2018.8.31)] 2018 International Conference on Information , Communication, Engineering and Technology (ICICET) - Performance Analysis of Battery for Solar based Wheelchair
摘要： Solar power system derive clean and pure energy from the sun. Solar panels are able to produce energy from the sun rays and convert it into electricity using photovoltaic effect. During this process panel generate no pollution and it is less costly. We have designed the solar based wheelchair for handicapped people. This wheelchair consists of solar panel, battery, charge controller, brushless DC motor. This report contains all the components information related to the solar based wheelchair. The proposed wheelchair system is self-driven so it is very useful for the physically challenged people. This is the best invention in the medical field. Early wheelchairs makes the use of grid supply for recharging batteries. Also the cost of those vehicles was not affordable for the common man. In this case an attempt is made to design a solar based wheelchair at an affordable cost so it can be affordable for the common man. It is useful in both indoor and outdoor activities.

[IEEE 2018 International Conference on Current Trends towards Converging Technologies (ICCTCT) - Coimbatore, India (2018.3.1-2018.3.3)] 2018 International Conference on Current Trends towards Converging Technologies (ICCTCT) - Analysis and Comparison of Charging Time between Battery and Supercapacitor for 300W Stand-Alone PV System
摘要： Among the available energy sources the energy through photovoltaic impact can be viewed as the most fundamental and sustainable resource as a result of the all over, sufficient and sustainability of solar radiant energy. Stand-alone solar photovoltaic system consists of storage device which stores the electrical energy in the form of chemical energy, and transforms this system electricity. Battery due to its low cost and ease of availability becomes one of the most conventional method of energy storage in all other standalone solar systems. Power generation from the solar photovoltaic system is an efficient energy storage business. Among the best energy storage device Super capacitor has a special place. It consist of unique properties that can praise other energy storage technologies. For factors like less charging time and rapid charging Super capacitors performs better than a conventional battery. It also have a better performance characteristics with improved system efficiency, high power density and discharging capability. The examination and comparison of batteries and super capacitor charging time for solar insolation at constant and time varying state is clearly clarified in this paper. It also explains the output voltage and current through load. Matlab/Simulink environment is used to simulate this 300W dynamic model of stand-alone solar PV system.
