Saskatoon church gives solar energy panels stained glass disguise

A new type of stained glass just installed in a Saskatoon cathedral is trying to prove green can also be glorious, combatting the stereotype of ugly, bulky solar panels.

When the Cathedral of the Holy Family needed a new set of stained glass windows, Toronto artist Sarah Hall jumped in with a project she's been working on since 2005 -- one that combines old art techniques with new technology.

Working with engineer Christof Erban, who pioneered the concept of placing a solar cell between layers of glass, Hall's solar-infused masterpiece is a colourful set of three giant windows set atop the Saskatoon church.

The work is called "Lux Gloria," or "Light of Glory," and the largest of the three windows measures 37-feet high by 12-feet wide. The windows -- a display of silver solar cells fused with various colours of stained glass -- simultaneously shade the church, harvest solar energy from outside and block out heat.

While the Saskatoon project is just one example of Hall's work in the field of building-integrated photovoltaics (BIPV) - her first installation went up in Washington, D.C., in 2005 - the Lux Gloria is the first of her pieces that feeds back into a city's electrical grid. She has also worked on two projects in Toronto, one in Vancouver and one in Camas, Washington.

Hall's studio said the embedded solar panels are capable of generating 2,500 kilowatt hours of power, or about 20 per cent of the electricity used per year in the average Canadian household.

SolarEdge Technologies - Solar Inverters, Power Optimizers and PV Monitoring

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
