Canadian provinces divide the territory in to vast areas with big differences between the latitude of the southernmost and northernmost locations. As the optimal solar angle mainly depends on latitude, we can't summarize it in one single number.
The town of Nain is the most northern location in Newfoundland and Labrador we have solar calculator reports for at the moment. The optimal angle for power generation is 42 degrees with a very slight 1 degree azimuth rotation. Keep in mind, azimuth offsets up to about 5 degrees are not very detrimential to the total generation. We have the full solar generation report for Nain here.
The southernmost town in Newfoundland and Labrador is St. Shott's. As we travelled south, the optimal solar angle decreased considerably to 33 degrees. At this angle, we calculated that the total solar power generation should be about 102979 kWh of energy for a 100 kWp solar plant. We have reports for 4 more angles to visit the St. Shott's full solar report here.
The usual info box:
Newfoundland and Labrador is a province located on the east coast of Canada. It is the most easterly province in the country, and is composed of two main land masses: the island of Newfoundland and the mainland region of Labrador. The province is known for its rugged, natural beauty, with its rocky coastline, forested interior, and picturesque fishing villages. It is also home to a rich cultural heritage, with a strong tradition of music, storytelling, and art. The provincial capital is St. John's, located on the east coast of the island of Newfoundland.
