Dear Mark,

The Energy Miser #16 January 28, 2008

Two newsletters in a month, this has to be a record.

No, I am not sitting on a beach in the tropics writing newsletters. I am huddled in my cold office, heated only by my computer's power supply and the remaining incandescent bulbs in the house wishing I were sitting on a beach in the tropics. Nevertheless, I am thinking about the sun and all that electricity we are missing out on...

Back in November, we added a Toyota Prius Hybrid to the "fleet" of vehicles. Our Prius is a 2004 with about 75,000 miles on it. With just under three months of use, we are quite happy with the vehicle.

When the weather is warm, it gets over 50 miles per gallon of gasoline. When the weather is cold, it gets about 40 mpg. (How you drive the car matters and Bill gets better gas mileage than I get. It doesn't hurt that his regular car is a Prius and his wife's car is a Prius too.)

We call it a truck because not only do we use it for regular business travel, but with the seats folded down and the roof racks on, we can move quite a bit of equipment.

Keep your eyes peeled for a white Prius with turbine blades, a stack of solar panels, or some rebar on the roof...
Commonwealth Solar - Residential Grants
As I mentioned in the previous newsletter, the Massachusetts Technology Collaborative was about to change the grant structure for solar electric systems. Well the new grant structure has been announced and the changes are most excellent. (Guess the reference and you will get a gold star).

If you are a Massachusetts customer of National Grid, Nstar, Unitil, or any other publicly traded utility, you are eligible for these grants.

Starting with residential systems:

If you recall, we speak of solar systems in terms of their rated peak production capacity. A 2,000-watt system, at any instant, will produce 2,000 watts of power under laboratory conditions. (In the real world, assuming no shade on your panels, true power output is about 80% of rated power.)

Item Grant Amount Comments
Base Grant Amount $2.00 per watt Maximum at 5,000 Watts
Massachusetts Made Equipment Adder - a major component of your system system must be substantially made in Massachusetts. $0.25 per watt We use Solectria Inverters made in Lawrence and/or Evergreen Solar panels made in Marlborough.
Moderate Home Value Adder - if the assessed value of your home is below the median assessed value for your county. $1.25 per watt $350,000 is median home value in Bristol, Suffolk, & Worcester County $400,000 is median home value in Barnstable, Duke, Essex, Middlesex, Nantucket, Norfolk, and Plymouth counties. Valuation based on a recent property tax bill.
Household Income Adder* for household incomes below Massachusetts median household income. $2.00 per watt Massachusetts median household income is $76,296 (1040 Adjusted Gross Income)
Household Income Adder* for household incomes below 120% of Massachusetts mean household income. $1.00 per watt 120% of Massachusetts median household income is $91,552 (1040 Adjusted Gross Income)
Shading Adjustment Sliding scale If a system is estimated to produce less than 80% of capacity, the grant amount will be reduced in proportion to the shading effects.
* Income verification performed by a third party under contract to the Massachusetts Technology Collaborative. New England Breeze will not be party to this information.

Some examples:

You live in Worcester County. Your home is assessed at $300,000. We install a 2,000-watt system using a Solectria inverter. Rebate amount: $2.00 + $0.25 + $1.25 = $3.50, $3.50 x 2,000 = $7,000

You live in Middlesex County, your home is valued at $550,000, we install a 3,600 watt system using a Solectria inverter and Evergreen solar panels. Rebate amount $2.00 + 0.25 = $2.25, $2.25 x 3,600 = $8,100.

And don't forget, If you pay income taxes :-), you are eligible for a state income tax credit of 15% (up to $1,000) of the system cost and a federal income tax credit of 30% (up to $2,000) of the system cost. (Credits are different than deductions, they reduce the tax you pay dollar-for-dollar. Of course, we are not accountants. Please confirm these tax benefits with your tax professional).
Commonwealth Solar - Business Grants
The Business grants are larger than those for residents and are designed to provide system payback time of 5 to 7 years. They are calculated based on system size and a sliding scale that decreases as the size of the system grows.

System Size -> 1kW to 25kW >25kW to 100kW >100kW to 200kW >200kW to 500kW
Base Incentive $3.25/Watt $2.50/Watt $2.00/Watt $1.50/Watt
Massachusetts Made Equipment Adder $0.25 per watt $0.25 per watt $0.25 per watt $0.25 per watt
Public Building Adder $0.50 per watt $0.50 per watt $0.25 per watt $0.25 per watt
In general, the $0.25 per Watt for Massachusetts made equipment benefits the buyer. Therefore, we will always specify Solectria Inverters and/or Evergreen panels unless there is a good financial reason not to.
Ready for a Solar Electric System?
What do you need for a solar electric system? Not Much really. South facing space clear of shade and standard electrical service.

South facing roof - A roof is a great place to put a solar system. Along with the primary benefit of generating electricity, a roof mount system is up and out of the way. It also keeps a large amount of heat off your house. Your house stays cooler and your shingles last longer.

We also have mounting systems for standing-seam metal roofs.

Don't have a south facing roof? Don't worry. There are also ground mount systems. An open, unshaded spot in your yard works as well as a roof. Ground mount systems stand on a pole and can be mounted from 4 to 10 feet above the ground.

Standard electrical service - The solar system plugs into your circuit panel using a normal 240-volt circuit breaker. No room in your circuit panel? No problem. We will add a sub-panel and plug in there.
Finance your Solar Electric System
We now offer financing through our distributor Sunwize Technologies and Meridith Capital Group.

Rates are based on the market and your credit rating. Rate is determined at time of application.

After we have specified a system and estimated its cost, You can apply on-line at Meridith Capital Group.

Turn off the lights, wear a sweater, keep a blanket on the couch, unplug unnecessary appliances, add insulation, take shorter showers, walk instead of drive, ride a bike, group your errands, inflate your tires, grow your own food, eat locally-produced food, recycle, use your most efficient vehicle, get a hybrid vehicle, wash your clothes in cold water, use a clothesline instead of the dryer, print with narrower margins, buy less, use both sides of the page, compost, put computer gear on a power strip and turn it off at night, install a renewable energy system...
