Farming and gardening is, of course, the original use of solar power, but the Maine Organic Farmers & Gardeners Association (MOFGA) went the next step and installed the 21st century evolution: an 11.7kw solar photovoltaic array. This grid-tied system has no moving parts, no batteries, just fifty-two Solon Blue 225 watt panels tied to two inverters that will convert sunshine into electricity for the next several decades.

This 21st century system marks the latest step in the restoration of a 200 year old barn – a true symbol of old tradition meets new technology! This unique and highly visible project was a great opportunity for some video coverage, and in this 7-minute feature we hear from Vernon LeCount from MOFGA and John Luft from ReVision Energy’s Liberty office about the installation and MOFGA’s long-term ambitions about renewable energy.

MOFGA provides year-round services to organic farmers and gardeners, but they may be best known for their big upcoming event: the Common Ground Fair to be held this September 23-25. The fair is the premiere celebration of rural traditions and sustainable living and attracts over 60,000 people each year.

We’ll be there the whole weekend with staff from all three branches. Be sure to keep an eye out for the new PV system as you approach the south parking lot, and talk to us about any questions you’ve ever had about solar, energy efficiency, and green building.

Thanks again, MOFGA, for making a big commitment to sustainable energy, and to Darryl Czuchra Production Services, who went above and beyond in the creation of this video.

The solar electric system on the fire station in Manchester, Maine will provide more than half the power for the building

The Town of Manchester, Maine, has one of the first solar-powered fire stations in the state! Last month we finished installation of a 9.2kw grid-tied photovoltaic array, which will provide over 11,000 kWh of clean energy annually – or roughly half of the power used in the facility.

The Kennebec Journal reported on the project. Keith Edwards writes:

A new array of 44 solar panels atop the fire station is expected to supply about half the electricity the building needs.

“It’s in, it’s making electricity right now,” [Town Manager E. Patrick] Gilbert said of the system.

The system is connected to the power grid, so when it is producing more power than is needed at the fire station, that excess electricity goes into the grid, and the town will get a credit on its bill from Central Maine Power Co. for that electricity.

“Whatever we don’t use dumps back into the grid,” Gilbert said. “There will be good (electricity-generating) days and bad days.”

… Gilbert said the location is expected to allow the panels to work at about 95 percent of their capacity … He said he hopes to ultimately make the system’s monitoring information available on the town’s website.

The project was supported by a grant from Efficiency Maine made possible by the American Recovery and Reinvestment Act.

The 18.3kw solar electric array on Supercuts’ Brewer location is expected to provide 100% of the energy efficient building’s electric loads!

On busy Wilson street in Brewer, perhaps the most striking building is the new Supercuts, which boasts a bold architectural design and a 18.3kw grid-tied solar electric system. According to building owner Carol Epstein, this is all by design.

“I wanted it to be visible, a statement, an advertisement – so everyone could see the panels,” she says in a Bangor Daily News article on the project. “We could have done a flat roof and put panels on a little stand, but we really wanted to show off the panels, so we did this big, pitched roof.”

In addition to making a strong environmental statement, economic conditions were right to make the Supercuts project a reality. With a 30% federal tax grant, accelerated depreciation which amounted to nearly another 30%, and a $2,000 state rebate, the project was reduced to close to a third of its original cost… Add to this a lower than ever cost of installing panels (around $4.5/watt installed for this project), and you have a very powerful case for solar electricity!

David M. Fitzpatrick of the Bangor Daily reported in a special section:

When Epstein Commercial Real Estate entered into talks with Supercuts, Epstein found the company’s vision of energy efficiency a good match for hers, and she and her team took the challenge of creating the new store very seriously. “We looked at their electric bills for three of their typical stores around New England to figure out how much electricity they use,” Epstein said. “We sized the system to that.”

Epstein Commercial Real Estate has been pushing for energy efficiency in several of its properties in the past four years, doing such things as installing energy-efficient lighting inside and outside, increasing insulation, and adding timers and motion sensors. “We’ve really looked at the whole spectrum with heating, lighting, air conditioning, insulation on all our properties,” Epstein said. “I think we’ve put in close to a thousand new lighting fixtures.”

… In addition to the solar panels, the building is very green in its design. It features big windows for plenty of natural light, low-watt fluorescent lighting, supplemental LED lighting, and many other features. As for the solar array, a remote control that looks like an electronic Rolodex allows you to flip through data screens that report the electricity being generated, or what was generated that day, week, month, and so on.

“Our tenant is very excited about it,” Epstein said. “They have a number of SuperCuts all around New England, and … they were designing this building — we were all designing it — to be their showcase in the area for SuperCuts.”

And of course, be sure to check out Supercuts next time you’re in Brewer. ReVision staffers report that nothing feels quite the same as a blow dry when you know the power is from the sun!

The 7.5KW grid-tied solar electric system on Black Dog Car Wash’s Dover location will save the business over $1,400/yr in electric costs.

How do you stand-out in the crowded world of car washes? For Black Dog Car Wash, it’s been dedication to an exceptional customer experience, state-of-the-art-facilities, and a commitment to the environment.

With water and energy conservation, pollution prevention, and biodegradeable soap options already in place, Black Dog decided that clean solar energy was the way to take their new facility in Dover, NH to the next level.

“Solar is Green Technology that our customers can see,” says Black Dog Car Wash’s owner, Jeremiah Gage, “We have been integrating green technology for years, but our customers rarely see these improvements that lie behind closed doors.”

Black Dog’s growth coincided with a great new rebate from the state of New Hampshire: an incentive payment of $1.00 per watt for solar electric systems. Combined with the 30% federal tax credit (which in 2011 can be taken as a treasury grant), Black Dog found they could save over $15,000 – more than half the cost of the system – as well as being eligible to take additional tax credits in the form of accelerated depreciation.

In addition to saving the car wash an estimated $1,440 per year, the system will offset 12,250 pounds of C02 emissions. The new facility also boasts energy efficiency lighting fixtures, which further reduce the facility’s environmental impact.  “We feel [solar] is what a successful business like Black Dog Car Wash should be doing to help reduce our environmental impact,” Gage continues, “Our goal is to integrate solar at all Black Dog Car Wash locations.”

Sun shines down on a set of solar thermal collectors installed on the refurbished Mill at Saco Falls.

Earlier this month music and celebration marked the opening of an old mill building in Biddeford that has been converted into housing units.

The 66 apartments Mill at Saco Falls showcase the greenest type of green building – taking an existing structure and repurposing it, preserving the building material as well as the cultural heritage of the historic structure.

Listen to the MPBN report:

The Portland Press Herald also reported:

[Nathan Szanton of Maine Workforce Housing LLC] said the project entailed maintaining the mill’s historic character while incorporating significant green features. For example, solar panels on the roof that heat water required strategic placing to keep them out of sight, because the modern look of the panels would detract from the historic appearance of the building

The solar thermal panels on the Mill at Saco Falls are arranged so that the street-view of the historic building is not affected – only the consumption of fossil fuels!

The solar array consist of 25 American-made flat plate solar hot panels that will produce more than 1,000,000 Btu’s of energy on a bright sunny summer day.

The solar heated water is pumped into a massive 1,350 gallon storage tank, which is plumbed into the main domestic water feed.

In the summertime, the sun alone will be enough to heat the tank for showers, dishwashing, etc. In the colder months it will serve as a pre-heat for an existing gas boiler.

The high-volume solar thermal system will provide more than half of the building’s hot water needs – saving over 3476 Therms of natural gas annually!

Standing atop the river that made Saco and Biddeford boom towns in prior centuries, the new project is a strong statement to the marriage of tradition and our renewable energy future.

Clean energy advocates in New Hampshire have two big reasons to be thankful this season – the New Hampshire Public Utilities Commission has announced an expansion of the solar hot water rebate available to homeowners and has released the application for their commercial solar hot water and solar electric rebate (PDF).

Here are some details on both programs:

Residential Solar Thermal is Hot

The solar hot water rebate in New Hampshire is tiered based on the performance of the system, which is expressed in MMBTU / year. This consists of a state rebate that ranges from $600-900 and a federal rebate which has been raised from $750 to $2,000.

Here’s what the rebate program looks like for different kinds of systems:

For a typical residential project (2 flat plate collectors which produce ~18.25MMBTU/yr) installed at a cost of around $10,500, the incentives amount to $5,750, well over half the cost of the system!

The rebates are retroactive, as well, so if you recently installed a solar hot water system and qualified for the New Hampshire state rebate, you can expect a holiday gift from the PUC soon.

Rebates Arrive for Business

The solar hot water system for Moat Mountain Brewpub will save the brewery an estimate 520 gallons of oil a year

Equally exciting is the arrival of the much anticipated commercial solar hot water and solar electric rebate.

This program makes $1,000,000 available to solar thermal and solar electric projects for businesses, schools, municipalities, apartment buildings – basically any structure not eligible under the residential program.

The rebates are pretty straightforward:

• Photovoltaic (Solar Electric): $1/Watt up to $50,000 (or 25% of the project cost, whatever is less)
• Solar Thermal rebate: $0.07 per kBTU/year up to $50,000 (or 25% of the project cost, whatever is less)

Like the residential solar hot water program, a RETScreen modeling analysis is used to calculate the kBTU/year performance of the solar hot water systems.  Solar electric is fixed based on the nominal wattage.

Solar Economics are Amazing

The generous rebate makes it extremely attractive to invest in solar if you’re a business.  Let’s take, for example, a medium scale solar thermal project for a business that uses a lot of hot water – a hotel or retirement home, perhaps – and is currently heating that water with oil.

We’ll propose a system of 20 flat plate hot water collectors and several super-insulated tanks that will produce over 182,500,000 BTUs/year of clean thermal energy.  We’ll imagine that the system will save 2,300 gallons of #2 oil per year, a result of both reduced oil use and greatly reducing standby losses of the oil boiler in the summertime.

Assuming this hot water system costs around $100,000 gross to install, the fuel savings alone will pay for the cost of the system within its first decade of operation.

However, now there is an exciting suite of rebates to apply:

$100,000 gross installed cost
($30,000) federal tax credit
($28,900) accelerated depreciation – avoided taxes over 5 years thanks to lowered net income, assumes 34% marginal tax bracket
($12,775) state rebate – $0.07/modeled kBtu/year
$28,325 net investment – less than a third of the total cost of the project!

Within this new context, that same solar hot water system will pay for itself within two years thanks to the fuel savings.

While the wasteful boiler imagined in this formula is a “best case” scenario for solar, the economics work out for businesses of all sizes who are ready to both take an enormous cut out of their carbon emissions and save money while doing it.

Aqua Maine’s new water treatment facility in Rockport uses solar hot water and solar electric systems which will work together to provide over 80,000 kw/hr of energy each year.

The Free Press, today featured our recent project with the Camden and Rockland Division of Aqua Maine.

The new $7.2 million wastewater treatment facility in Mirror Lake in Rockport features both solar electric and solar hot water systems.

The solar systems will work in tandem to provide more than 75% of the needed energy to heat 2,500 gallons of treated lake water to 95° F each day (a feat that requires up to 1,209,300 BTUs in the wintertime!).

According to The Free Press:

The new facility uses more power to push water through the filters, and the microfiltration membranes must be periodically cleaned with heated water. Rick Knowlton, vice president of operations, says, “While the original design of the facility included a large electric heater to warm water for the membrane cleaning process, we knew that this would be a perfect application for a solar thermal system to supplement or reduce the use of the electric heater. Almost 2,500 gallons of warm water will be needed every day, and the solar system being constructed should reduce our purchased electricity by 80,000 kWh every year. It’s one of the larger solar systems installed in Maine.”

Over the first 20 years of its life, the system is expected to save over $210,000 in electric costs. And according to The Free Press, “the power savings have been passed on to the Camden & Rockland Division customers as part of the recent Maine PUC decision on rates.”

Not only will Midcoast Mainers benefit financially from the project, but they can breathe a little easier, too. The solar system will offset roughly 1.27 million pounds of C02 each year, the equivalent of planting over 3,600 trees.

The solar collectors atop L.L. Bean’s flagship store are a visible symbol of their commitment to using sustainable energy whenever possible.

L.L. Bean, the iconic Maine outdoor apparel and equipment retailer, took one more step towards their corporate goal of reducing their greenhouse gas emissions 20 percent by 2012 with the installation of a solar hot water system on their flagship store in Freeport, Maine.

The system consists of 180 evacuated tube solar hot water collectors which heat twin 80 gallon Stiebel Eltron solar hot water storage tanks.

The closed loop system contains non toxic antifreeze which pumps from the tanks to the collectors, where it is heated by the sun, and then back to the storage tank where it passes through a heat exchange coil to heat the domestic hot water supply.

From May to September the array will provide nearly 100% of the hot water used for the flagship store’s employee shower, custodial basins, 2 cafes and 29 sinks.  Beans’ existing propane hot water heater serves as a backup.

“This system can heat enough water on sunny days so that we won’t need to fire up the water heaters in the store,” says George Croston, HVAC Senior Supervisor in Facilities and the project manager for the solar panel installation. “On overcast days and on cold days in the winter, the system will still preheat water so that we’ll use less energy to get it up to the right temperature of 120 degrees F.”

Here is a video of ReVision cofounder Fortunat Mueller (who designed the system) explaining how it works:

L.L. Bean: Showing People Solar Works

“We want visitors to see these solar panels and make the positive connection that L.L.Bean is investing in and promoting renewable energy,” says L.L.Bean Senior Public Relations Representative Laurie Brooks. “The more businesses that make these types of changes, the better. It’s our hope that eventually green technology will become mainstream, and prices for solar technology will become more affordable.”

The solar hot water investment is part of larger environmental stewardship efforts by L.L. Bean, which include upgrading lighting systems throughout the company, converting heating systems to natural gas (from oil and propane) and implementing a corporate energy policy.

“In concert with additional energy efficiency projects, [the solar hot water system] will allow us to achieve our EPA Climate Leaders goal of reducing our greenhouse gases 20 percent by 2012,” adds Laurie. Climate Leaders is a voluntary partnership between industry and government that encourages companies to develop long-term strategies that reduce CO2 emissions.

L.L. Bean has also committed to build all new structures according to the US Green Building Council’s LEED standards and has converted their heavy-duty truck fleet to biodiesel fuel.

You can learn more about L.L. Bean’s environmental commitment on their website.

Making Solar Affordable

L.L. Bean expects to use 850 fewer gallons of propane each year with the new system, resulting in a savings of nearly $1,900 in fuel costs in the first year alone, and more than $51,000 in fuel savings over the warrantied 15-year life of the solar heating system. The system should last much longer than that—the solar panels L.L. Bean installed on the roof of their Taylor Building in the 1980s are still producing hot water for that building’s restrooms and employee showers decades later.

“In addition, use of renewable energy, in concert with additional energy efficiency projects, will allow us to achieve our EPA Climate Leaders goal of reducing our greenhouse gases 20 percent by 2012,” adds Laurie. Climate Leaders is a voluntary partnership between industry and government that encourages companies to develop long-term strategies that reduce CO2 emissions.

The project was made possible in part thanks to an Efficiency Maine Commercial Grant funded by the American Recovery and Reinvestment Act.

The stimulus funding reduced payback projections for L.L.Bean’s new hot water solar system to less than 5 years, with immediate cost savings. 

Next time you visit Freeport, be sure to keep an eye open for the system, which sits to the right of the legendary Bean Boot on the flagship store (on the roof of the camping area).
