When planning a DIY off-grid solar setup, most people price out the "Big Three": panels, hybrid inverters, and battery banks, and think they have their total budget figured out. The reality? Balance of System costs, heavy copper wiring, specialized tools, and ground mount prep can easily add thousands to your final bill.

In this Unplugged LIVE replay, Adam and Eric walk through the hidden budget killers that catch DIY solar builders off guard. They cover where you can safely save money, where cutting corners will cost you big time, and the 30% rule: plan to spend at least 30% more than your Big Three components cost.
