Powering up the system Wiring up the enphase monitor The Enphase microinverters comes with a monitoring system called Envoy. This will allow you to see how much electricity you are producing and consuming. You install two consumption meters and one production meter in the main panel and then run those wires to the monitoring system. The meters and the wires […]
Summary Each solar panel produces DC voltage which goes into a separate micro-inverter for each solar panel. The microinverter converts the DC voltage into AC voltage. The micro-inverters are chained together and run into a junction box where it then connects to 14 gauge wires that run to the disconnect switch. Then the wires run from disconnect switch to dual […]
Getting Panels to the Roof The solar panels are 7 feet tall. It would require four people; two at the bottom lifting up the panel and two on the roof to receive the panel. Because of the COVID lockdown I couldn’t have anyone over to help lift the panels to the roof. So I decided to build a solar panel […]
Process Overview In Walnut Creek there is an expedited process for PV systems under 10kw. The expedited process doesn’t require licensed electrician or structural engineer. I submitted my permit application package as one pdf by email. It took 2 days to get an approval email telling me to pay $450 online and sign a couple more forms ( build owner […]

For this project I installed a 2.4kW (7 x 340w), micro-inverter, no battery, on-grid solar system on a flat one-story TPO membrane roof. Working a few hours a week, it took me 6 months from the time I got the solar panels, researching, preparing the permits, building the ladder hoist, installing the flashings, to powering up the system. I received […]
I was looking for a stretch project to broaden my DIY skills and I wondered how difficult it was to install a photovoltaic (PV) system. In the past year I had completed several home improvement and repair projects around the house: replaced backyard patio trellis installed new irrigation system and grass for backyard installed retaining walls and low voltage lighting […]
