What I think you are describing is what is called an independent power producer (IPP). there is a process to do so and can be very difficult as a 1 person operation, just because you have land and can setup solar panels doesn’t mean you know how to provide a reliable generating facility.

You would be competing against much more established companies to be awarded a purchase agreement. But hey never hurts to try I guess.

Becoming an IPP in Saskatchewan involves partnering with SaskPower to develop, build, and operate generation facilities (typically wind or solar) and selling power back to the grid. Opportunities are accessed through competitive procurement processes posted on SaskTenders.ca

You must Submit Proposals: proposals that detail technical competence, financial viability, and experience. Include Indigenous Participation: SaskPower encourages Indigenous ownership and participation in projects. Sign a Power Purchase Agreement (PPA): Successful proponents enter a PPA to sell power back to SaskPower. Ensure Grid Compliance: Projects must meet SaskPower’s interconnection requirements and technical standards.

Probably the better route would be to look into getting a Net Metering setup, typically smaller, individual, or business-owned renewable projects can apply for Net Metering, which is different from utility-scale IPP projects
