  • "Update of Earlier Review"

    Reviewed Jan 25, 2019

    After reconsidering, talking with Rebecca and several years of trouble free operation, I thought I should write a new review to offset my earlier negative review. The installation went smoothly and the system has performed as anticipated, At this time Rebecca has been attentive in developing an upgrade to install battery backup. I look forward to working with Waldo again.

  • "Waldo Renewable Caps Project"

    "Waldo Renewable Caps Project"

    Reviewed Jan 14, 2019

    "Extreme Performance" was the energy benchmark for a new single family home in Stonington, Connecticut. Designed from the solar PV array down, the three bedroom, 2.5 bath house is also a Passive Solar design with geothermal heating, Heat Recovery Ventilation systems, a Thermomass® concrete shell and extensive green roofing.

    Waldo Renewable came in on the recommendation of CM John O'Keefe, after the owner had disappointing experiences with the national rooftop solar firms. Mark redesigned the original 10Kw system to 12.15Kw while keeping costs down and the layout clean, then followed with fast and meticulous installation, inverter grid hookup and testing — while wiring an option for future storage batteries.

    What began as a "net-zero capable" home is now a "net-plus" home, and the owners are thrilled. Waldo Renewable Electric LLC should get six stars!

  • "Living Sustainably"

    Reviewed Jan 11, 2019

    Mark and Rebecca of Waldo Renewable lives and work have a consistent ethic - that is to help create a resilient and sustainable world. It is enthralling to meet a company and individuals whose personal and corporate goals are consistent with one another. The residential solar array they installed on my home was done in a professional manner and both Mark and Rebecca were, and continue to be a pleasure to deal with.
