I'm looking for some guidance on solar and potentially wind power solutions for my 900-square-foot home located on an island. Since the environment is coastal, I need a system that can withstand salt exposure. Additionally, the electrical infrastructure here is unreliable, so I'm interested in an off-grid system that also has the capability to connect to the grid when needed. I'm feeling a bit overwhelmed by the options available. Can anyone recommend specific systems they've used or share insights on things they wish they'd known before starting their renewable energy journey?

Before diving in, it's essential to assess your energy needs. Do you have your power bills from the past few years? They can give a really good idea of your consumption. Understanding what you really need versus what you'd like is the first step in finding the right system.
For a coastal environment, consider brands that build equipment for marine use, like Victron. Their gear is designed to resist saltwater. Also, I’d suggest bi-facial or glass-to-glass solar panels since they last longer in salty conditions. As for wind, it's a little tricky—you really need to know your average wind speeds to see if it's even worth it!
If you're flexible with your budget, I recommend looking into a combination of solar panels, battery storage, and a fossil fuel generator. The total cost, including installation, might run between $50,000 to $60,000, but it will give you the power to both connect to the grid and go off-grid whenever you need.
