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 accelerating worldwide growth in grid-tied PV will be driven by a number of
factors including: improved technology, cost reductions, strong deployment incentives,
growing consumer interests, renewable portfolio standards, climate change concerns, and a
host of other policy mandates.

The number of relatively large PV projects feeding power directly to the grid will increase, but
most systems will be deployed in behind-the-meter applications, where the technology
competes with the retail rate of delivered electricity rather than the wholesale cost of energy
supplied by central-station generating plants. In fact, worldwide PV sales have surpassed $10
billion annually and total installed PV capacity is projected to exceed 25 GW by 2011.

As a result of the growing demand for PV, the outlook for inverters used in PV systems is
expected to remain strong. There are a large number of PV system configurations available
and a wide range of inverters on the market. Some models use transformers and some are
transformerless, and many come with sophisticated communications and monitoring systems.

Regardless of the type of inverter used, the system is usually configured in traditional central
inverter architecture. Since the PV industry is constantly evolving, inverter manufacturers
must continually design new products.

Despite the ubiquitous nature of the central inverter system, it has a number of limitations. It
relies on one device (the inverter) that when faulty, brings down the entire system, and its
inherent design means the weakest panel in each string eliminates the benefits of the better
performing PV panels. (The “weakest link” module determines the string current and has a
disproportionate impact on overall PV system performance.)
