Return on investment (ROI) analyses of solar photovoltaic (PV) systems used for residential usage have typically shown that at least 10 to 12 years is needed to break even, with this amount varying based on tax credits and reliability. This paper discusses the challenges with the reliability of current solar photovoltaic systems and the key reliability bottlenecks, with a focus on the ROI. The problem...
Growing solar PV energy generation must be coupled with low cost monitoring schemes for its wider uptake. Conventional grid-tied PV systems, deployed generally in the developed countries, are supplemented with information available through weather stations and other established means. However, emerging regions of Africa and South Asia require low cost local monitoring for resource optimization, preemptive...
