The percentages are Google’s own arithmetic over every review it holds, not a sample we assembled. Separately we hold 26 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

    Wow…not sure where to start. Josh and his team are top-notch. From the initial consultation to the final product, we were overwhelmed with this team’s attention to detail. Nuts, bolts, hand-made (marine quality) battery cables, heat resistant cement backer-board, etc, the list goes on…And no wonder he’s sought after in the Marine & RV solarphere! Every aspect of our experience, and communication from start to end, was beyond expectation. They took in our Brinkley Z2900 and turned her into a boondocking goddess! Many thanks to his entire, and dedicated, team for providing us an amazing off-grid

    Josh rewired our boat to accommodate a larger inverter and 3000W of solar, including installing new solar panels, controllers, and the inverter. He also corrected a poor installation left behind by a previous contractor on our Lagoon 450. The project involved completely rewiring the boat’s main electrical system so the inverter could reliably run the air conditioning. His workmanship was exceptionally neat, and the final result was both well organized and safe. Despite the complexity of the job, Josh completed everything on time and stayed on budget. He maintained a consistent schedule through

    I am very happy with my Victron equipment which I purchased via CIS Solar. Josh provided outstanding service by helping me establish what equipment I needed for the DIY project I was kicking off. He is very knowledgeable and has an in depth understanding of the Victron equipment capabilities and integration. Thanks Josh for the service. Top notch Victron dealer!

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

What we don't know

  • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
  • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
  • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
