Why did the industry move from 600-V to 1000-V solar arrays? The answer is simple: to reduce system costs. The value of increased system voltages is realized in infrastructure savings, reduced installation costs and end-to-end efficiency improvements. That is the same reason the industry is now moving from 1000 volt systems to 1500 volt systems. Learn more about challenges to the step-up, efficiency and cost considerations and why the move to higher voltages is so important to the industry overall.
