A new 3.6 kW PV array part and a Deep Energy Retrofit (part of National Grid DER Pilot Program) give a 100 year old farm house an energy efficiency make-over.

What You Need to Know

Description:

Sunpower 3.6 kW PV system includes super efficient panels that allowed for maximized use of small roof space.

Other Benefits:

PV expandable to second roof should we get a plug in car or need to increase system size. Installation included conduit and potential for expansion.

Efficiency or Sustainability Improvements:

Deep energy retrofit of the house (see separate project lisitng) included adding 4" rigid foam to exterior walls, 5.5" foam on exterior of roof and 3-4" of spray foam at the foundation. Also replaced windows with triple-glazed low e windows, and air-sealed house to reach .08 cfm/SF @ 50 PA, to minimize heat loss from air infiltration. Low VOC paints and finishes used on floors/walls/cabinetry.

My Motivation:

#1 Goal: Lower our carbon footprint and use significantly less fossil fuels in an attempt to live more sustainably.

Advice:

Consider your building envelope first, before looking adding renewable energy.

Experience with Installer:

PV Squared was terrific. From the initial assessment to the final walk through, they made the process simple and efficient. They were extremely professional and delivered what they promised.
