DIY solar projects go sideways for so many reasons
There are tons of crap kits on the internet put together by computer geeks with soft hands that just "move boxes". The stuff is junk, incomplete, and creates more questions and confusion. Speaking to building and safety can be confusing too. The forms can be confusing, the instructions can be short. It can create significant unnecessary delays.
Understanding how permitting, utilities, and inspection actually work takes experience.

I’m Jeff Van Dam — a licensed California solar contractor based in Southern California.
For over 15 years I've been designing, permitting, installing and servicing residential solar systems. Now it's my time to share all of my wisdom to help those who want to install their own system
I’ve worked directly with AHJs, utilities, inspectors, and plan reviewers.
I’ve seen what gets approved, what gets rejected, and why systems fail long before the first panel goes on the roof.
I've seen what equipment is essential, what's not so important, and what to stay away from.
I've installed on every type of roof, residential and commercial. Balasted and ground mounts systems too.
That experience is what I bring to your project — without installing it for you.
This is simply consulting, design assistance, and professional guidance — nothing more, nothing less..
I have several ways to make you confident, your self-installation easier and save you thousands of dollars and weeks of time

Purpose:
This is the emotional hook — subtle, not cheesy.
The solar guy your neighbors ask questions.
The solar guy friends call for advice.
The solar guy who did it right.
Every Pro DIY Solar Package includes a That Solar Guy T-shirt — not as merch, but as a badge.
