Executive Summary

Led by the developing photovoltaic marketplace (PV), the outlook for inverters employed in Option Energy Resource technology is expected to remain powerful. Business development in this application will be driven by a mixture of government incentives and declining PV module costs. Projected to make up more than 95% of the market, the inverters employed in PV installations, both tiny (1-5kW) and massive (&gt6MW), will far outpace these utilised in either wind or fuel cell applications.

Driven by the want to develop option sources of energy, limit greenhouse gasses and lessen the dependence on foreign energy supplies, the market place forces driving the alternative power resources market differ by region. In Europe, the principal driving forces are feed-in tariffs, which have been successfully utilized in 16 EU nations, most notably Germany, Italy and Spain. In fact, in Europe renewables comprise the fastest-developing segment of the energy marketplace. In North America, as opposed to Europe, the alternative energy sector is driven by a combination of regulations, subsidies and tax incentives and legislation. In contrast, Asia employs a patchwork technique of incentives including subsidies and other government actions. In this region, the primary concentrate on alternative energy is the alleviation of energy shortages and the development of backup and emergency power.

A specifically considerable technological and architectural trend includes the continued improvement of Constructing Integrated Photovoltaic (BIPV) systems. A BIPV technique includes integrating photovoltaic modules into the developing envelope material and power generators. Proof of this can be observed in the number of productive BIPV projects worldwide, ranging from person residential units to massive commercial developments. . The improvement of BIPV systems is also substantial because in buildings, it can play a lot more roles than solely producing electricity. As an instance, Sharp tends to make translucent solar PV panels that incorporate light-emitting diodes (LEDs) to provide illumination as
effectively as energy.

The emergence of technologies developed to address the issue of PV shading is another area of anticipated growth over the subsequent many years. Considered one particular of the greatest challenges facing photovoltaics, a small quantity of shade can lead to disproportionate energy loss of more than 50%. 1 fully shaded cell can decrease a solar panel’s output by as considerably as 75%. In a response to this challenge, a quantity of organizations are establishing merchandise especially made to counter the effects of PV shading in both the residential and commercial sectors.

The move towards transformerless inverters has also produced important strides in the PV business more than the previous many years. In spite of concerns about security, size limitations and the lack of technological maturity, they are considered considerably more effective and can be developed at a much a lot more competitive value. In fact, transformerless inverters continue to advance around the globe and have achieved a international market place share of about 70%. Added developments in inverter technologies include improvements in communications and monitoring and the trend towards longer warranties.

The trend towards far more efficient inverters has also produced considerable progress. In an effort to improve the efficiency of the technology, semiconductor organizations are creating discrete IGBTs, MOSFETs such as CoolMOS as effectively as Silicon Carbide (SiC) devices in power modules and stacks, with the objective of raising solar inverter efficiency to 98 %, and with the purpose of feeding as considerably solar-based electrical energy into the power grid as attainable. A number of semiconductor companies are developing technologies designed to improve efficiency and lessen electricity waste to a minimum.

Despite the efforts of a quantity of government and regulatory bodies worldwide, the goal of interconnection and regulatory standards is nonetheless a work in progress. However, there are
a number of groups operating on electrical interconnection standards with the objective of reducing or removing barriers among distributed generation technologies and the utility grid. A survey completed found that most projects, which includes PV, wind and fuel cells, meet some sort of resistance from the utility firms when they attempt to interconnect with the grid. The high-priced and sometimes hard interconnection requirements presently in location worldwide comprise a essential barrier to the elevated use of option systems. 1 of the far more interesting technologies being created to drive interconnection is the improvement of a “smart grid.” Nevertheless, removing current interconnection requirements is not as easy as changing the policies, and a technique of resolving these barriers is ongoing.

In spite of the attention given to huge multi-megawatt wind farms, which are projected to continue increasing, both in size and quantity of installations, most of the possibilities for inverter manufacturers are in the tiny wind turbine market (

Though the smallest of the three applications presented in this report, fuel cells present an additional crucial opportunity for inverter producers. Eighty percent of the fuel cell
units presently made serve the stationary marketplace in a quantity of capacities, including combined heat and energy (CHP) applications, distributed generation on-site energy and backup power. An particularly essential development is the FCC 07-107 requirement to offer eight hours of emergency backup power at remote terminals or wireless web sites and 24 hours of energy backup at central offices or switch websites. As a result of this FCC requirement, the telecom industry presents a promising growth chance for the fuel cell sector.

In addition, the price of refurbishment and replacement of the existing constructing stock, combined with the new ultra-efficient housing/creating laws such as these described in the European directive (2002/91/EC), contribute to a developing industry for residential micro-combined heat and energy. Fuel cells are an enabling or bridging technology which can let the environmental and efficiency advantages of CHP to migrate into the residential industry. In this respect, fuel cell technologies represent a industry opportunity for the clean generation of electricity and provision of hot water and heating.
