Order Focus: Sustainable Energy delivers PV inverters for 1.8MW solar power plant in Czech Republic


Sustainable Energy Technologies has begun deliveries of its solar power inverters to Tejados Industriales de Fotovoltaica (TIF), a leading Spanish EPC company, affiliated with Signet Solar, for a 1.8MW thin-film photovoltaic solar power plant located in the Blizkovice region of the Czech Republic. The Canadian inverter company says the installation marks the first time that its parallel system architecture power devices will be used in a megawatt-scale PV plant.

The solar plant, which is being jointly developed by Signet and Czech project development company BSC-Solar, is scheduled for grid connection before the end of 2009. The Signet amorphous-silicon TFPV modules will be wired in parallel using Sustainable Energy’s patented Paralex solution.

“This order is a testament to the growing appreciation for the value of the Paralex operating system in Europe, not only for rooftop solar PV systems but also for ground-based solar plants” said Robert Bucher, president/CEO of Sustainable Energy. “We are also pleased with our new relationship with the TIF Group, to whom we are supplying inverters for this and other projects.”

Paralex is an operating system architecture enabling thin-film solar modules to be wired in a massively parallel array. The company says that its patented technology allows each solar module to operate independently of any other module in the system, ensuring that every module delivers its maximum power potential while decreasing the impacts of shading, soiling, and other real-world factors.

“We are very pleased to see the Paralex solution in the marketplace and optimized for Signet Solar modules,” commented Klaus Mueller, managing director of TIF. “We believe our Paralex/Signet Solar system will provide a superior performance ratio to any other solution available today.”

“A ‘parallel system architecture’ is a concept that the PV industry has been waiting [on for] some time but until now developments have focused only on standard crystalline-type modules,” he continued. “In our opinion, Paralex is the most economic way to optimize the power output and reap the benefits of parallel architectures.”

Sustainable Energy says it will supply inverters from existing inventory, with first European deliveries of the second-generation units expected to start later this year.

The demand for rooftop solar PV is soaring, driven by falling costs of the technology against energy crises that are gripping countries globally. But while an increasing number of households turn to solar to generate their own electricity, there is now a need for more specialist equipment, technologies and services to ensure the solar transition can reach as many customers as possible. Delivering these is now a major challenge for rooftop solar installers. This webinar will analyse the characteristics of the rooftop solar market, discussing how the products, logistics, installation and servicing of solar systems has evolved in line with consumer demands.
