BURNABY, BC: On the renewable energy front, Day4 Energy Inc. is set to break into the UK solar market with its new solar modules, and Sustainable Energy Technologies has announced significant advances in its power control technology that will translate into lower costs and greater efficiencies for its SUNERGY inverter line.

Day4, a global provider of solar photovoltaic (PV) products based in Vancouver, said it has received Microgeneration Certification Scheme (MCS) status, which allows it to sell its 60MC-I solar PV modules in the UK.


MCS certifies micro-generation technologies used to produce electricity and heat from renewable sources, and is required for end users to benefit from a feed-in tariff (FIT) launched by the UK government in April 2010.

Day4, referring to a recent industry report, said the UK experienced unprecedented growth in solar PV demand with installations reaching an estimated 45 megawatts last year, up from just 4 megawatts the previous year. Demand is expected to exceed 146 megawatts this year.

“Most PV modules are designed to perform well under ideal conditions. The Day4 60MC-I performs exceptionally will in a wide range of conditions – particularly those affecting rooftop installations in the UK,” said George Rubin, president of Day4. “The Day4 60MC-I module featuring Guardian Technology is three times less sensitive to the effects of time-of-day shading from chimneys, trees or buildings – significantly increasing the amount of electricity produced when compared to the performance of conventionally designed modules.”

Sustainable Energy Technologies Ltd. has achieved “significant advances” in the transformer topology for its solar inverter line following more than a year of collaborative research with the Faculty of Engineering at the University of Alberta. Funding was provided through Alberta Advanced Education and Technology.

The SUNERGY manufacturer said the concepts, subject to several pending patents, were validated in production scale prototypes at the its labs in Calgary and development of the first commercial product platform incorporating the new topology and controls is underway with delivery targeted for this year.

The controls will increase peak efficiencies above 97%, which Sustainable Energy said is among the highest in the industry and will lead to reductions in manufacturing costs across a range of power ratings. The transformer topology will also mean lighter weight, smaller platforms for lower power ratings suitable for residential markets later this year.

“We are very excited about the outcomes,” said Brent Harris, chief technology officer and a co-inventor of the company’s technologies. “Not only has the research contributed to achieving our near term commercial goals – namely lower cost and higher efficiencies – we have collaboratively achieved what we believe to be several scientific breakthroughs in transformer design that will open the way to a range of new product opportunities.”

SUNERGY’s parallel architecture achieves maximum energy production by isolating losses from shading, dust coverage and obstructions to panels, adding 5% to 15% more power, said the company.
