What does commercial solar cost in California?

There is no single number. Commercial solar cost in California depends on whether the array goes on a roof, a carport, or the ground, on system size, and on what your utility interconnection requires. Carports run higher per watt than rooftops; larger systems run lower. MYNT has designed, built, developed, and managed 118 projects, roughly 13 MW, so the honest answer starts with a load-profile analysis, not a rate card.

Why is there no standard price per watt?

Because the structure is most of the job. A rooftop array on sound structural steel is the cheapest install; a carport adds foundations, columns, and steel of its own; ground mounts add civil work. System size moves the number the other way: mobilization, engineering, and interconnection costs spread across more watts as the system grows.

Then the utility weighs in. Interconnection can be a simple application or a service upgrade with transformer work, and you don't know which until the load and site are studied. Any firm quoting a per-watt price before that study is quoting someone else's building.

How do you get a real number for your building?

Start from the meter, not the roof. MYNT models your interval data against your utility tariff first, then sizes the system to the value it can actually capture: self-consumption, demand-charge reduction, and storage arbitrage under NEM 3.0. The output is a project-specific cost and a project-specific return, engineered before a single panel is specified.

That analysis is the first thing we produce, and it's free to start: one conversation, one site walk, one number.
