Disruptive Technologies Affecting the PV Industry
HTML clipboard
The emergence of disruptive power architectures including microinverters and dc-dc converters will be one of the most important trends in the photovoltaic (PV) market in the near-term. The 75-page first edition of “Disruptive Technologies Affecting the PV Industry, Microinverters and DC-DC Solutions: Economic Factors, Application Drivers, Architecture/Packaging Trends, Technology and Regulatory Developments” is the first report available that details these important trends. ( http://www.bharatbook.com/detail.asp?id=127921&rt=Disruptive-Technologies-Affecting-the-PV-Industry-Microinverters-and-DC-DC-Solutions-Economic-Factors-Application-Drivers-Architecture-Packaging-Trends-Technology-and-Regulatory-Developments.html )
The shortcomings inherent in the central inverter architecture are expected to provide a host of opportunities for several new technologies. In fact, there are a growing number of companies developing products and technology specifically designed to generate more power from the PV panels already on the market. A distributed inverter architecture using either of two specific disruptive technologies, microinverters or dc-dc solutions, are expected to present a significant challenge to the conventional central inverter architecture over the coming years. A significant advantage both of these disruptive technologies have over traditional central inverter technology is the ability to perform maximum power point tracking (MPPT) at the panel level. Due to variation in shading, dirt, and aging of solar panels, individual panel voltages will vary, causing the output voltages of strings of panels to vary.
In addition to improvements in efficiency, the ability to reconfigure PV arrays without additional complex string calculations and improved operational flexibility, another opportunity for both microinverter and dc-dc solutions is the further development and availability of communications systems for both commercial and residential PV systems. Manufacturers of disruptive technologies such as microinverters and dc-dc solutions have picked up on this trend and are incorporating them
The demand for technology to address the problem of PV shading is another area of opportunity for both microinverters and dc-dc solutions. Due to the nature of solar array configuration, small amounts of shade (for example, shading of less than 10 % of the surface area of a PV system) can lead to disproportionate power losses of more than 50%.
One completely shaded cell can reduce a solar panel’s output by as much as 75%, and three shaded cells can decrease 93% of the panel’s output. Common causes of shade include structural objects such as trees, chimneys and dormers, and intermittent debris including falling leaves, bird droppings, dust and clouds passing overhead; unavoidable challenges that cannot be engineered out of an installation. In an effort to promote the use of disruptive technologies such s microinverters and dc-dc solutions, a number of microinverter and dc-dc solutions manufacturers have adopted a strategy of partnerships and alliances within the industry. In fact, a number of solar suppliers and utilities have made either alliances or acquisitions of distributed electronics vendors in what is clearly a validation of the potential for both of these new disruptive technologies.
