Why I No Longer Recommend Full DIY Solar for Most People

DIY can still be technically possible, but the compatibility and safety risks are high enough that most homeowners should not do it alone.

Over time, too many DIY cases failed not because the homeowner lacked effort, but because the permitting rules, approved equipment lists, and communication requirements between components were more complex than expected.

Some people buy batteries and inverters that cannot legally interconnect. Others discover too late that the equipment cannot talk to each other or that cable choices created safety hazards.

If someone still wants to DIY, professional review is not optional. With 240 V power and battery systems involved, safety has to come before savings.
