Bill Laberge, the founder of Grassroots Solar in Dorset, Vermont, has long been interested in sustainable living. He spent many years producing his own hand-made furniture, raising a family with his wife Lisa, dreaming of living a sustainable home, and even volunteering to work for SolarFest. Things began to change as the children became more grown up and spent less time at home.

We might say some things change and some do not. There were two big decisions to be made. Perhaps the more momentous was about where to live, and the couple decided that the place they loved most was where they were. But the other decision was about sustainability, and it entailed having Solar Pro, of Arlington, Vermont, install a 9.5-kilowatt solar system.

As the new solar system came alive, Laberge decided he wanted to share the experience with friends and neighbors, so he had a party. The party was such a success that the next day he had a new job at Solar Pro.

He worked at Solar Pro for two years, pushing the company to expand to new areas. His employers’ business plan was not the same as his, but they felt there was a lot of room in the market and suggested he might like to have a business of his own. They had trained him, but they did not need to hold him back. And so, in the beginning of 2015, he started Grassroots Solar.

Since that time, he has completed 19 installations. Most of these were solar installations, though there are many types of those, including off-grid and grid-tied, both with and without battery backup. They have installed roof-mounts, ground-mounts and trackers.

One thing that Laberge takes real interest in, however, is storage. He has taken a keen interest in batteries, and has looked deeply into the different technologies that are available. He regards Elon Musk’s announcement of the Tesla Powerwall line as a watershed event, because it made people serious about storage. The interest the Tesla batteries created did not blind him to other manufacturers, however, and he is happy to talk about the pros and cons of such batteries as the Encell, Juicebox, and Aquion.

Laberge’s expertise in off-grid systems has led to his being chosen for some very interesting work. One job that is particularly exciting is the solar and battery system for Emerald Lake State Park, in Dorset, Vermont. This project was announced by Green Mountain Power (GMP) late last summer. The situation was that park’s electric service was provided by a line that went through over half a mile of bad terrain, including marsh and swamp. It required $7,000 to $8,000 of repairs each year, usually because of trees that fell on it, and access slowed work greatly. When the state needed extensive work at the end of the winter, the engineers at GMP did the cost calculations and found that there would be a 20% saving if the park went entirely off-grid, using a solar system with batteries. The Vermont Parks Division loved the idea. And so did Laberge.

Laberge also takes great interest in smart metering and demand response. These, he says, offer both consumers and utilities opportunities to see some real cost savings. Utilities have long had the problem that the wholesale cost of power they had to buy at high demand times was often higher than the retail price they were allowed to charge. Smart metering and demand response allow customers the opportunity to defer use of power when demand is high, putting off consumption until demand and costs are low, saving money for both themselves and the utility. “Businesses that are feeling the burden of Peak Demand charges would help themselves by looking into peak shaving through battery systems,” Laberge has said.

Laberge expects this year or next to bring us to the point the economics of battery backup systems fall to the level that ordinary users can make economical use of them, regardless of whether they have renewable power generating systems. If that is the case, then we are on the cusp of yet another energy revolution.

    Can you do a system that is an emergency one that can power a well pump, furnace, refrigerator and a couple of lights? Can it fit in a small area and about how expensive would it be?

  • As publisher of Green Energy Times, I want to recommend that you look into RELiON batteries. They are probably the most reliable battery backup option out there. I speak from personal experience with them. They have made my living off the grid to be fossil fuel free — even with a small 3.8kW solar system — in fall and winters as cloudy and without solar gain as we have just experienced. My generator has not even come close to having a need to come on. These lithium batteries are awesome and work! No maintenance, no fumes, longevity, worth every penny. And they would work just as good if you are on the grid and want some assurance for the amount of power you seek for emergency situations. Don’t hesitate to look into them: AND they can fit into a small area with no problem!

    I feel quite certain that the folks at Grass Roots Solar could put in a system to meet your needs.

  • Bruce, Yes we can do a system that will take care of all of your essential loads. We need to figure out what those loads are and size the system accordingly. Well pumps typically have a heavy draw so they need a larger inverter than most systems. We also need to see what wattage you need for your furnace etc. I’m happy to provide a worksheet for you to figure all of that out. Email me;
