Electric ferry ecosystem for sustainable inter-island transport in the Philippines: a prospective simulation for Davao City - Samal Island Route

In this paper, an Efficient Method for PHotovoltaic Arrays Study through Infrared Scanning (EMPHASIS) is presented; it is a fast, simple, and trustworthy cell-level diagnosis method for commercial photovoltaic (PV) panels. EMPHASIS processes temperature maps experimentally obtained through IR cameras and is based on a power balance equation. Along with the identification of malfunction events, EMPHASIS offers an innovative feature, i.e., it estimates the electrical powers generated (or dissipated) by the individual cells. A procedure to evaluate the accuracy of the EMPHASIS predictions is proposed, which relies on detailed three-dimensional (3-D) numerical simulations to emulate realistic temperature maps of PV panels under any working condition. Malfunctioning panels were replicated in the numerical environment and the corresponding temperature maps were fed to EMPHASIS. Excellent results were achieved in both the cell- and panel-level power predictions. More specifically, the estimation of the power production of a PV panel with a shunted cell demonstrated an error lower than 1%. In cases of strong nonuniformities as a PV panel in hotspot, an estimation error in the range of 9–16% was quantified.

Using EMPHASIS for the Thermography-Based Fault Detection in Photovoltaic Plants

As the earth, together with all of its countries and people enlarge its envelope of power options to meet burgeoning energy requirements and progressively rigorous environmental worries, solar power is cropping up as an alluring option. In evolving countries like India where over the population of 300 million still do not have access to electricity; this source of electricity procreation becomes more extensive. Like any other power plant, a solar power plant in operation demands maintenance as well. Also, as the solar power plant gets old, operation and maintenance (O&M) becomes more and more vital for enhancing or keeping up the performance of the plant. This paper has conferred the present scenario of solar power in India. This paper has also enlisted the components of solar system. Various issues that arise in the operation of solar power plant are deliberated. Maintenance strategies in order to overthrow these concerns have also been explained.

Issues and Maintenance of Photo-Voltaic cell based system

P V solar power plants are planned to work for long time, monitoring of plant will ensure a safety and longterm operation. The photovoltaic system degradation of 10% per year in the year 1991 has reduced to 12% for 25 years due to modules manufactured after 2000. Some of the common and basic degradation issues in pv solar plants are discussed in this paper. The adequate maintenance is required for long term operations and increasing performance.
