Power from the Sun
Every 88 minutes, enough sunlight reaches the Earth’s surface to power the world for a year
Every 112 minutes, more sunlight reaches the Earth’s surface than is stored in all the proven oil, coal, and natural gas reserves in the world

What makes a good site?
http://energy.ltgovernors.com/solar-energy-pv-systems-self-generation-make-your-own-power.html
• Southern exposure •PV panels angled 30˚ – 45˚ • At least 4-6 hours of direct sunlight • Open roof area of ~100 sq ft per 1 kW • Open space for a ground or pole mounted system
![Page 14: Solar 101 - Franklin 8/20/14](https://reader033.vdocuments.mx/reader033/viewer/2022051513/54583dd5b1af9fcf338b53ac/html5/thumbnails/14.jpg)
How Does Solar a PV System Work?
Grid-connected projects can apply for Net Metering (utility meter spins backwards)
Power outage: Inverter shuts down, unless a battery-back up system is installed
![Page 15: Solar 101 - Franklin 8/20/14](https://reader033.vdocuments.mx/reader033/viewer/2022051513/54583dd5b1af9fcf338b53ac/html5/thumbnails/15.jpg)

Shading of Solar PV Systems
Initial site feasibility can be
determined online through
aerial images
A shading analysis should be
performed for each feasible
project site
Solmetric SunEye
Solar Pathfinder

Solar Renewable Energy Certificates (SRECs)
Electricity Pathway • Electrons from all
generation sources are
physically the same
• Cannot be tracked
independently on the
grid
SRECs Pathway • SRECs represent the
“green” attributes of the
renewable generation source
• Utilities are required to
purchase SRECs every year
• 1 SREC = 1,000 kWh
• Verified SRECs ensure
that only one buyer can
claim each SREC
Electricity and SRECs can be, and often are, sold
separately

SRECs (cont.)
Will be able to sell SRECs for 10 years
Likely sell from $285 - $199 per SREC
Work with aggregator or broker to help with the sale
Monthly production reported to MassCEC’s
Production Tracking System (PTS)
SREC II Program began accepting new applications in
early May 2014
