Most ADU projects require a panel upgrade anyway. Bundle both services with Yealpha and save on labor, permits, and coordination — while maximizing your federal tax credits.
Yealpha Construction & Energy is a licensed general contractor serving all of Southern California. We specialize in high-end residential renovations and ADU construction — and now offer complete electrical upgrades, battery storage, and solar installation through our Energy division.
Yealpha built our ADU from foundation to finish. Permitted, on time, and the craftsmanship is exceptional. Highly recommend.
Our bathroom remodel exceeded every expectation. The marble work, the lighting, the fixtures — everything is perfect. Worth every penny.
Had them upgrade to a 200A Smart Panel and install a Tesla Powerwall. The whole process was smooth, permitted, and the team was professional.
We recently upgraded to an EcoFlow Smart Panel 3 with battery backup through Yealpha, and the difference is night and day. The installation was clean and professional, and the team walked us through everything. Now we can monitor and control exactly how our home uses electricity — which circuits run on battery, when to charge, when to draw from the grid. During the last outage our house stayed fully powered. Couldn't be happier with the investment.
