• Solar module price has dropped 5x in 5 years to under $1 / Watt
• Balance of system costs now dominate. Our system reduces and firms this cost.
• Assured Quality and installation time through process optimization

EZ = easily installed (and uninstalled, if ever necessary) • Modular drop-in PV system
• Workshop assembled – hardware and wiring
PV = PhotoVoltaic aka solar electric (photo = light, voltaic = electricity)

• “EZ-PV” system moves much of the “on-roof” work to the workshop. Actual onsite installation takes much less time. The result is lower cost while ensuring quality control.

A roof (house, barn, etc.) or field with sufficient uninterrupted space to hold the PV modules
Roof can be oriented in directions from due East, through South, to due West (“true” rather than magnetic orientation)
No or limited shade from trees or other obstructions—enough clear view to receive average of 6+ hours sunlight per day
If this is, or might be, your home, give us a call!

“But costs may keep falling. Why shouldn’t I wait a few years?”
Vermont incentive not reliable… Federal tax credit expires 2016… Solarize Norwich incentives Every year you wait is another year you buy electricity
while generating none… Given air pollution, energy security, & climate change
concerns, whether choosing EZ-PV or Solaflect or any other source, if you have the means and the location, you should act.
