Now Offering Solar Canopies: A Beautifully Designed Structure that Harvest Sunshine

ReVision Energy now offers the installation of timber-framed solar structures, similar to this one located at Vermont-based solar installer Suncommon (a fellow B-Corp). These beautiful and flexible structures are weather-tight, spacious, and feature unique bi-facial solar panels, meaning they are able to absorb reflected solar energy from ground surfaces to increase their overall efficiency. The… Read more

Solar Panels and Solar Inverters: The Tools that Drive Solar PV

ReVision Energy has been installing solar electric (also, photovoltaic, or PV) arrays in Maine, New Hampshire, and Massachusetts since the early days of the industry, when collector sizes were very modest and systems were truly only suited for remote locations where grid connections were not possible.  We’ve witnessed the introduction of grid-connected solar electric systems, which… Read more

Solar + Batteries Vs. Generators: Batteries are Increasingly Competitive

ReVision Energy is pleased to announce that as of October 2016, we are a Tesla Energy Certified Installer, meaning we are authorized to install the Tesla Powerwall and Tesla Powerwall 2. This certification adds to our extensive and diverse experience designing and installing advanced energy storage systems from Sonnen, Pika Energy and Adara, as well… Read more

Battery Storage (supplemented by solar) vs. Generator

Our mash-up: solar-powered battery storage vs. a home standby generator. NOTE: the cost of solar is not included in the chart below. This is intended to help a solar customer who is weighing home standby power options with whether to add on a battery pack, or get a fossil-fuel powered generator. While there are some… Read more

2016 Update: The Many Ways to Go Solar

Stunning progress in solar technology has positioned humankind to make the quantum leap from fossil fuels to clean energy in the coming decade, just as the advent of the automobile enabled the radical transition from the horse and buggy to cars a century ago. The 75% decline in cost of solar electric panels over the… Read more

Energy Independence = Solar + EV + Heat Pump + Battery

Phil Coupe, one of ReVision’s co-founders, leads this inaugural (and occasional) column offering perspectives from ReVision Energy’s leadership team as they look at our progress in transitioning New England to a clean energy economy and the opportunities and challenges ahead. Abandoning gas stations has been one of the more liberating experiences of my lifetime (rivaled… Read more

Library in Lovell, ME Powers Up with Solar and JuiceBox Battery Backup

ReVision Energy was grateful for the opportunity to partner with JuiceBox Energy for the installation of an 8.1kw solar electric array paired with a next-generation 8.6kWh lithium-ion battery system at the historic Charlotte Hobbs Memorial Library in Lovell, Maine. The project was the first JuiceBox battery storage system installed in the Northeast and was made possible with a… Read more

Most of the recent attention being paid to residential and… Read more

How Mitsubishi Mini Split Heat Pumps Work

Air source heat pumps are a highly efficient form of electric heating, that work on the same concept as your home’s refrigerator or a window air conditioner running in reverse. Rather than heating air molecules with electricity, they extract heat that already exists in outside air and move it into your home. This is possible even at temperatures well below zero. In heating mode, refrigerant is pumped through the outdoor unit, where it absorbs heat. The hot refrigerant is then pumped through the indoor air handler, where it releases the heat into the home. In summer, the unit works in reverse, extracting heat from the home and moving it outside, providing ultra-efficient cooling. Since the heat pump moves heat, rather than creating it, it is much more efficient than traditional electric heating systems, and in fact has an overall efficiency of 250%. Read more
