The panel in white

Slovenian solar module maker Bisol has unveiled two new colored PV panels based on the company’s Spectrum product type.

Available in alabaster white and terracotta orange, the two products are claimed to add aesthetic features to the architectural traits of buildings and roofs of various types and styles. “Orange glass matches the shades of Dutch buildings and brick roofs all around the world and maintains the color recognition of the environment,” the manufacturer explained. “White glass is a great solution for seamlessly blending with large surface buildings and maintaining their historic character.”

“The coloring is done on the inner side of the glass, so the color is much more durable and resistant to all weather conditions,” a company’s spokesperson told pv magazine.

The Spectrum module with the colored glass is a 60-cell monocrystalline product relying on 3.2 mm glass with anti-reflective coating and high transparency. It is sold in three versions with power outputs of 190, 200 and 290 W, and an efficiency of up to 11.4% for the white panel. For comparison, the Spectrum modules without the colored glass would have an efficiency ranging from 18.9% to 20.5%.

The panel measures 1,665 × 1,002 x 35 mm and weighs 18.8 kg. The open-circuit voltage is between 40.3 V and 43.5 V and the short-circuit current ranges from 6.00 to 8.75 A. The maximum system voltage for the new product is 1,000 V.

The panel can be used with operating temperatures of between -40 degrees Celsius and 85 degrees Celsius. The operating temperature coefficient is -0.37% per degree Celsius. It features an IP68 enclosure rating and an MC4-compatible connector.

The two modules come with a 25-year output guarantee and a 15-year product guarantee. The manufacturer claims the panels will operate at 85% of their original performance after 25 years.
