We frame it, wire it, and power it.
Van Mierlo Builders and Solar is a licensed California general contractor that does the construction and the energy system — solar, battery storage, panel upgrades and EV charging — under one license, one crew, one point of contact.
Most solar companies subcontract anything that involves a saw. Most builders subcontract anything that involves a conductor. We hold the license for both, which means the roof, the framing, the service panel and the array get planned together instead of argued about later.

The unglamorous work that makes everything else possible — and the most common reason a solar or ADU project stalls.
California's current net billing rules pay very little for the power your array exports at midday, and charge the most for the power you pull back after sunset. That single fact changes how a system should be designed.
Pairing solar with storage lets you hold your own production until the expensive hours, and keeps the lights, the fridge and the well pump running when the utility goes down.
