Where is the best place to plant solar panels?

Could you please elaborate on the factors one should consider when determining the best location for installing solar panels? Is it purely about maximizing sunlight exposure, or are there other crucial considerations such as the angle of the panels, the location's climate, and potential shading from nearby structures or trees? Additionally, are there any regulations or zoning laws that could affect the placement of solar panels on residential or commercial properties? It would be helpful to have a comprehensive understanding of these aspects before making a decision.
