As module prices have fallen—dropping roughly from $4 per watt in 2006 to $0.60 per watt in 2016—the costs for BOS components in general and electrical BOS (eBOS) components in particular have become a larger percentage of installed PV system costs. Moreover, the industry has largely identified and leveraged the low-hanging fruit of eBOS cost reductions, such as increasing the nominal system voltage on nonresidential systems from 600 Vdc to 1,000 Vdc and making widespread use of aluminum rather than copper conductors on large-scale systems. So where will eBOS cost reductions come from next?
By Scott Wiater - Revolutions in financing have cemented solar energy as a mainstay of U.S. energy production in the residential and utility market segments. But one segment of the solar market still struggling to find its footing among finance professionals is the commercial and industrial (C&I) segment.
By Scott Wiater, President - "Despite the sustained and nearly unprecedented growth in solar installations in recent years, current news surrounding SunEdison’s bankruptcy and other underperforming public companies, combined with the state-level utility/solar squabbles over net-metering, has some potential customers nervous about investing in solar."
