Photovoltaic Array Reliability Optimization
TL;DR: In this article, the authors present a statistical reliability analysis of photovoltaic component design with respect to cell failure, interconnect fatigue, glass breakage, and electrical insulation breakdown, and propose a means of selecting the cost-optimal level of component failures, circuit redundancy, and module replacement.

Abstract: Several statistical reliability studies have been conducted in areas of photovoltaic component design covering cell failure, interconnect fatigue, glass breakage and electrical insulation breakdown. This paper integrates the results from these studies and draws general conclusions relative to optimal reliability features for modules. The analysis is based on designing for specified low levels of component failures and then controlling the degrading effects of the failures through the use of fault tolerant circuitry and module replacement. Means of selecting the cost-optimal level of component failures, circuit redundancy, and module replacement are described.

Proposed method for determining the thickness of glass in solar collector panels
D. M. Moore
- 01 Mar 1980
TL;DR: In this paper, the minimum thickness for simply supported, rectangular glass plates subjected to uniform normal pressure environmental loads such as wind, earthquake, snow, and deadweight was determined by comparing an analytical prediction of the stress in the glass panel to a glass breakage stress determined from fracture mechanics considerations.
