"Jeremiah and his crew did a fantastic job. They arrived on time, worked very hard in the small hot attic space, did not waste time and were very professional. Jeremiah explained from start to finish what the job entailed. When the job was completed, Jeremiah explained all that was done and wanted to make sure we were completely satisfied before leaving.

NON-PROFIT organization. Save on heating oil with local dealers, all year long. Our Heating Oil Service works like a buyers club or co-op for home heating oil and is available to most households in Massachusetts, Rhode Island, and southern New Hampshire. We use the group buying power of our 11,000 members to negotiate a discounted price per gallon with vetted oil dealers every day of the year. How it works: 1. Enroll in the program and pay your annual membership dues ($25 for a basic 1-year membership). 2. Once you’ve enrolled, we pair you up with one of the oil dealers in our network that meets your delivery, payment, and service preferences. 3. Every time you receive a delivery from your new Mass Energy oil dealer, you get the discounted member price per gallon instead of the price they charge their regular customers. That's it! As a bonus, we'll help you save even more on energy by helping you make smart decisions around energy efficiency and renewable energy upgrades. (Formerly doing business in Massachusetts as Mass Energy and in Rhode Island as People's Power & Light.)

"Always pleasant interactions with staff. You can tell that they are proud of what they do and are genuinely invested in the company’s causes."

SolarFlair works with businesses and homeowners that are interested to reduce their utility bills and their carbon footprint by converting to solar power. We are a licensed and certified solar engineering and design firm with over 10 years of experience in the industry. We do not use subcontractors and have over 200 satisfied clients that are happy to share their SolarFlair experience.

"The original installation process went very smoothly, however,, A few years after the panels were installed, a leak developed at one of the punctures for the panel mounts. we first called back the roofer to see if the leak was not due to the solar mounts, but he confirmed that the leak was indeed right under one of the mounts. SolarFlair came to take a look and applied a product to the interior of the roof which did nothing to stop the leak, they came back and applied roof tar on the outside which again did not stop the leak. this process has been very frustrating for the lack of communication, the slowness and incomplete response to the issue. They've closed out the work each time they've done something before veryifying that the leak has been fixed (it still has not been fixed). The company had taken over 9 months from our inital call, and we still have a leaking roof. we have very little communication from SolarFlair as to what actions they have taken, and what next they could do. it seems clear that part of the roof needs to be replaced to fix the leak."

Energy Efficiency Auditing questions, answered by experts

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours. 

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.
