I'm considering investing in a solar panel system, but I'm unsure how to determine the right size and configuration to meet my energy needs effectively. Can you provide guidance on key factors I should take into account? Specifically, I'd like to know how to evaluate my energy consumption patterns, roof space, and local climate conditions to make an informed decision. Additionally, it would be helpful to understand the different system configurations available and how they align with my requirements. Any insights into the benefits of grid-tied vs. off-grid systems would be valuable as well. Also, could you advise on whether I should include battery storage in my setup? I'm looking for clarification on these aspects to ensure that I make the best choice for my situation.
