- Solar is less expensive than retail electricity before incentives in many cases today!
Average cost of system installed in MA over last year = $3.52/W (utility, commercial and residential), which results in an approx. levelized cost of energy of 12.4 cents/kWh over the 25 year warranted life of the system.
- The solar industry employs over 119,000 people – more than the coal industry, and is one of the fastest growing industries in the US.
- $22 of incentives go to the fossil fuel industries for every $1 of subsidies that go to renewable energy.
- Over 70% of the net additions to the world’s electric grids were renewables last year.
- The costs for solar panels have fallen by over 60% in the last year and a half.
- Residential systems in MA typically pay back in 6 years.
Typical 6kW system saves 5 tons of CO2 annually – this is about 18% of the carbon footprint of a typical family in Wellesley (assumes 4 family members, nat. gas heating, 2 cars with 240 miles/mo. and 20.4 mpg, recycles most waste)
- Removing 1 car from the road
- Planting 1 acre of pine or fir forest
- Recycling 1.8 tons of waste instead of sending it to a landfill
Cost of Solar
Avg. residential system size in MA: 6kW (would supply about 2/3 of the average Wellesley home’s electric usage)
Cost for avg. residential system in MA last quarter: $4.41/W, or $26,500
Commonwealth Solar II Rebate: ($2,000)
Federal 30% Investment Tax Credit: ($7,950)
MA Tax Credit: ($1,000)
Net System Cost: $15,500
Annual Electricity Savings @ 12.6₵/kWh: $850
($29,000 over 25 year life of system, assuming 3% annual electric rate growth)
Annual Solar Renewable Energy Certificate (SREC) Income: $1,900 – $3,700 ($19,000 – $30,000 over 10 years)
15% return on investment, about a 6 year payback
Power Purchase Agreement (PPA) – zero cost initial investment, plus buying electricity at lower cost from solar array owner
Solar Lease – zero to minimal cost initial investment, savings on electricity, plus lease payments to solar array owner
How to Start
- See if you have a roof face that faces mostly south
- Check for shading (if no or limited shading at noon in mid-winter you’re probably in good shape)
- Go to www.masscec.com (Massachusetts Clean Energy Center) and search “Finding a Solar Installer” or contact me, Alex Keally – email@example.com, 617-217-1502.

Many walk/run by the Golembewski-Wilson home with little understanding of the true inspiration it is.
Beyond their incredible lawn and gardens, there is so much more.
As the family is passionate about sustainability, they have given careful thought and consideration to their footprint. They have created a variety of systems – as well as some fabulous guests — to benefit their family as well as the environment.
For those that missed them on Sustainable Wellesley’s House Tour, here is a quick synopsis that will have you re-evaluating and tweaking some of the processes in your home.
Some of these ideas you have heard about, and some you havent. For example:
The Doggie Dooley
This In-Ground Pet waste disposal system comes in handy with the family’s 5 rescued dogs. It enables them to contain all their solid waste and allow it to decompose naturally on their property. The Doggie Dooley has been around for 40 years.
The Compost Bins
The family has a 4 bin 4’ x 4’ composting system where they compost all feasible organic material on their property. The compost is then used to supplement their garden beds and top dress the lawn to improve the fertility and soil structure naturally.
The two rain barrels they have on their property are used to collect water to irrigate their nursery stock as well as for their containerized plants.
The family has adopted seven chickens as companions. They have four bantams and three standard chickens. The hens have been a wonderful addition to the family and the property. Not only are they entertaining to watch, but they do a fair share of work as well: they provide the family with eggs, help with insect control (grubs and ticks are some of their favorites), dethatch the lawn while scavenging, and provide nitrogen rich droppings for the compost piles.
This is a composting system that uses worms to turn organic matter into soil. In the winter time when the snow is too deep and the family can not get to their compost piles, they are still able to continue composting with the use of the vermicomposting system.
Many years in the making, the family has created a vegetable garden made up of 11 raised beds. The beds themselves are constructed with a recycled plastic “wood” and allow for intensive agriculture. They utilize vertical trellises to make the most of the bed space. They not only eat out of the garden throughout the summer, but also manage to extend the season a bit with the use of cold frames (harvesting carrots and brussel sprouts in January!). The garden provides more than enough produce for the family, with ample to share with the dogs, chickens, friends, and neighbors.
The family has designated a tiny space inside their back hall to contain their recyclables. Based on the products that the RDF recycles, they created an efficient area to sort and store their recyclables. It takes about a month before the family has to bring the containers to the RDF!
With all organics being composted, and everything possible being reused or recycled, as a family of three (plus their multitude of companion animals), they only generate approximately one kitchen size bag of trash every two to three weeks.
Now its your turn.
What is your green story?
Thanks to the Golembewski-Wilson Family for sharing and inspiring us!
