  • 7. 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
  • 8. Is There Enough Sun In MA?

  • 13. 13 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
  • 14. 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
  • 15. 15 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
  • 16. 16 Aerial photos 4. 1. 2. 3. 5.
  • 17. 17 What adds costs to an installation? Structural • Reinforce Rafters • Split Arrays/ Multi Roof • Metal Roof • Steep Roof Electrical • Service Change • Supply Side Tap Other • Ground- mounted System • Data Acquisition System • Extended Warranty • Increased shading  Common Cost Adders
  • 18.  Introduction  Solar PV Basics  Solar PV Incentives and Economics Outline
  • 19. High electricity prices + Reduced Solar PV Costs + Numerous Incentives = Economical solar projects Solar Incentives in Massachusetts www.house-power.com/blog/wp-content/uploads/2009/12/iStock_000009001180XSmall.jpg Incentives Tax Incentives: Federal (30%) State (15% up to $1,000) Rebates from MassCEC Net Metering SREC Sales Low/No money down options
  • 20.  Quarterly funding blocks  $1.5 million available  Residential, commercial, non- profit & public solar PV systems ≤ 15 kW  Rebate capped at 5 kW  Proposed rebate ranges from $1,250 to $3,500 for 5kW system  Rebate covers ~5% of Installed Cost Commonwealth Solar II Rebate Program Block 19 Rebate Levels ($ per watt (DC @ STC)) Base Incentive $0.25 PLUS: Massachusetts Company Component Adder $0.05 Moderate Home Value Adder OR Moderate Income Adder ≤ 120% of MA median income (only residential projects eligible) $0.40 Natural Disaster Relief Adder $1.00 Go to www.MassCEC.com/solar to learn more.
  • 21. MassCEC Rebate Program (cont.) County Property Value Berkshire, Franklin, Hampden, and Hampshire ≤ $300,000 Bristol, Suffolk, Worcester ≤ $350,000 Barnstable, Duke, Essex, Middlesex, Nantucket, Norfolk, and Plymouth ≤ $400,000 Income Category Income Levels Individual Income ≤ $75,810* Domestic Unit Income ≤ $95,420* Moderate Home Value Adder Criteria * 120% of median household income as determined by the US Census Bureau Moderate Income Adder Criteria
  • 22.  Experienced Installer  Minimum Technical Requirements  Equipment must meet certain standards  Required warranties − Panels have 20 year warranties − Inverters have 10 year warranties − 5 year workmanship warranty  80% of optimal system production MassCEC Rebate Program (cont.)
  • 23. 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
  • 24. 24 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
  • 25.  Outright purchase  Third party ownership Ownership Models
