Canadian Solar supplied its CS6P-P modules for the PV system and the plant was constructed on the grounds of a Bulgarian food and beverage company Philicon 97.

Philicon 97 project manager Ivan Kalibatsev said the company has compared the offers from various module manufacturers and at the end opted for Canadian Solar and EPC company Solarpro.

"The excellent customer service and high product quality were critical for our success," Kalibatsev said.

"We are very pleased with the result and our expectations have been exceeded. Already in the first month, the power output of the solar system was 15 percent higher than expected."

The solar power plant was connected to the grid in February 2012 and benefits from a feed-in tariff of 0.25 euros per kWh and supports Philicon 97.

Canadian Solar is a vertically integrated provider of ingot, wafer, solar cell, solar module and other solar applications, and it designs, manufactures and delivers solar products and solar system solutions for on-grid and off-grid use to customers globally.
