Large grid-tie inverter systems are becoming more prevalent, and export energy credits from feed-in-tariffs help defray the large capital expenditure -- but a sub-par power factor could bring penalty charges from your utility. Gerritt Lee explains the problem and offers a solution.
Small variations in cell parameters can affect the system-level performance of a PV array. National Semiconductor's Ralk Muenster explains how distributed maximum power point tracking (MPPT) enabled by power optimizer technology can solve the panel mismatch problem.
As the result of a memorandum of understanding signed this week, ACCIONA Solar Power and the Clark Energy Group will develop a large-scale solar energy project--the first phase, consisting of five sites that total 500MW--at Fort Irwin in California's Mojave Desert.
Morgan Technical Ceramics has developed fused silica rollers designed for use in solar energy applications.
Spanish photovoltaic engineering and supply company PROINSO has signed a collaboration agreement with Belgian engineering company Nizet to provide modules, inverters, and fixed structures for Belgium’s largest solar farm.
California state officials have signed new legislation for what they call "a model of federal-state initiative and cooperation" for reviewing and applying funding for renewable energy development, in a push to meet a mandated goal of a third of its energy received via renewable sources by 2020.
Jef Poortmans, IMEC's program director for photovoltaics, sat down with PV World during the research center's annual media event in Leuven, Belgium, (Oct. 5-6) to discuss his outlook for organic PV technology.
