The battle of the solar microinverters is heating up, and here’s one potential Trans-Atlantic match-up. On one side you’ve got U.S.-based Enphase, which has shipped 1 million microinverters at home and is planning an IPO. On Monday the Petaluma, Calif.-based startup announced that it’s invading Europe via France, Belgium and the Netherlands, where its devices have passed Continental standards and are ready to be installed. On the other side you’ve got Enecsys, a British startup with only tens of thousands of European solar rooftops carrying its microinverters, though it claims a big potential advantage in Germany. On Tuesday the startup announced a partnership that allows it to sell in Canada’s Ontario province’s lucrative solar market, its first big landing on North American shores.

SunSil Drives Electronics Deeper Into the Solar Panel
Greentech Media
Sunsil of Denmark has upped the technology ante in the integration of PV solar modules and power conditioning electronics. (...) Microinverters and panel optimizers maximize output for each module; SunSil's design goes a step further and adds their "dynamic microcell controller" at the solar-cell level within the module and addresses this cell variation, as well as panel shading and panel soiling. Maximum Powerpoint Tracking is being done at the cell level and the panel puts out alternating current.
Sunsil takes a backside-contact, 17-percent-efficient solar cell, scribes it with a laser and breaks the cell into sub-cells. Each solar module uses 576 sub-cells, along with 48 DC-to-DC converters. (...) With production help from Dutch firm Eurotron, SunSil is building a 300-watt, 230-volt AC module (ACM) -- one that produces 20 percent to 40 percent more kilowatt-hours per year than a standard module.
Hansen claims inverter efficiency of better than 96 percent, using space-grade components. The end product is guaranteed for 25 years.

Microinverter With 25-Year Warranty From SolarBridge
Greentech Media
SolarBridge Technologies, a developer of power conversion solutions for the solar industry, announced the launch of the SolarBridge AC Module System, a microinverter that enables the industry’s first integrated AC modules with a full 25-year warranty. The company is partnering with photovoltaic (PV) module manufacturers to bring AC modules to market. Kyocera Solar and SunPower are two of these partners. If you're going to build a microinverter integrated with a solar module, it makes sense that the microinverter should rival the lifetime of the panel itself.
As with all microinverters, the SolarBridge product improves energy harvest with the potential for improved reliability and reduced installation costs. The SolarBridge microinverter replaces today’s junction box and is integrated directly onto the back of a solar module during module manufacturing. The SolarBridge microinverter requires a fraction of the bulk capacitance of traditional inverter architectures, enabling the use of long-life film capacitors. This is a component design decision different than that of the leading solar microinverter firm.

PV Inverter Scene Overhauled by Micros and the AC Module
Central inverters may currently dominate photovoltaic installations but a distributed inverter architecture using either micro-inverters or AC-DC solutions is set to mount a growing challenge. See a recent review at RenewableEnergy.com
Some recent developments in this area:Petaluma-based Enphase makes microinverters that increase the efficiency of solar panels. It has sold 400,000 of the microinverters since it started business in 2008. Paul Nahi is its president and CEO. Suntech (NYSE: STP) makes solar power systems for use on homes, businesses and by large industrial and utility customers. It’s based in Wuxi, China. Its local head office is in San Francisco.The two didn’t give financial or other details of this agreement.
National Semiconductor announced today that it is collaborating with Suntech to develop “smart panel” technology, incorporating National Semiconductor’s award-winning SolarMagic™ power optimizer chipset into Suntech solar panels to improve the power output of solar systems. National’s SolarMagic power optimizer chipset enables each solar module to produce the maximum energy regardless of whether other panels in the array are under-performing due to environmental mismatch. The technology enhances the energy harvest of each individual PV panel through a combination of advanced algorithms and leading-edge analog power management circuit techniques. In real-world tests involving shading and mismatch, Suntech modules with SolarMagic power optimizer technology were shown to recoup an average of 50 percent of lost energy, and in some cases captured as much as 75 percent of otherwise lost energy compared to standard panel performance.
