For years, I'd debated whether residential solar would make sense for my home. The math never quite clicked, and I refused to go into debt by signing a $30,000 contract or leasing agreement with a door-to-door solar sales company. It wasn't until the end of 2025 that the market finally forced my hand.

The combination of a steady, upcoming increase in electricity rates, the impending January 1, 2026, expiration of federal tax rebate incentives, and battery tech actually improving in recent years made a far-off "maybe one day" dream into an achievable DIY project. The announcement that a new hyper-scale data center was going in a few towns over made the decision to finally jump in a no-brainer.

Many of my tinkering projects are driven by curiosity. I like to see if I can accomplish a goal without paying as much as expected, and I'm admittedly motivated by the feeling of getting away with an unexpected hack. Channeling a little ingenuity and effort feels like an arrogant middle finger at being told what I have to buy, and nowhere was that feeling more satisfying than in this solar project. If you've been thinking similarly about making the leap to solar power, I know how intimidating it can be. But in my experience, the squeeze was well worth the juice I got in return.

Today a DIY system usually means a fully integrated system from a single Chinese supplier: hybrid inverter, BMS and batteries together. That is no hack, and no major difference (other than price) from what a professional company installs.

Having such a system absolutely raises the price of the house sold. Maybe not a full cost recovery, but enough to not make it a total loss if you end up selling before the usual return of investment period.
