Description
With the rise of solar PV systems in Canada, many engineers are grappling with the complexities of power generation from these evolving technologies. This course covers essential aspects such as solar site assessments, installation techniques, and financial considerations related to design and operations. You will dive into DC and AC system losses, gain insight into the operation of string and utility-scale inverters, and explore project scheduling within the context of utility-scale solar farm projects.

In addition to technical designs, this course offers an in-depth understanding of grid-connected solar farms at both medium and high-voltage levels. Topics include medium-voltage (MV) and high-voltage (HV) distribution, AC collector circuits, substation conceptual designs, and system commissioning. Participants will also address compliance with local utility requirements, ensuring a comprehensive grasp of solar PV system commissioning processes.

By the end of this course, you'll be fully equipped to tackle the complexities of designing and operating solar farms, from understanding civil works and environmental aspects to ensuring regulatory compliance. The course is structured to provide practical knowledge that enhances your ability to integrate solar technologies into grid systems and optimize performance.

Who Should Attend
This course is ideal for engineers, designers, and technical professionals in power generation, solar project management, and electrical system integration.

The practical insights and hands-on knowledge shared throughout the course will benefit electrical designers, project managers, electricians, and operating engineers. Additionally, sales engineers, installation teams, and solar project owners will gain valuable skills to enhance their expertise in PV solar systems.

Furthermore, individuals involved in solar farm development, utility compliance, or integrating battery energy storage systems (BESS) will find this course particularly useful. Those responsible for designing or overseeing medium and high-voltage solar installations are also encouraged to attend.
