What - How Does Solar System Work? Grid-connected projects can apply for Net Metering (utility meter spins backwards)
Why - Net Metering Example System Size – 5kW (5,000 watts) Annual Production ~5,600 kWh Annual Usage Onsite ~7,500 kWh December Produce 150 kWh Use 600 kWh Pay for 450 kWh on electric bill July Produce 800 kWh Use 600 kWh Receive 200 kWh credit (in $) Net Metering!!
Why - Massachusetts Residential Electricity Prices MA US Sources: EIA 2011 Data
High electricity prices + Reduced Solar PV Costs + Numerous Incentives = Economical solar projects Why - Solar Incentives in Massachusetts Purchase Incentive Mass Commonwealth Solar II rebate Residential energy tax credits Production Incentive Net Metering Solar Renewable Energy Certificates (SRECs)
How - 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
How - Ownership Outright purchase Power Purchase Agreement Lease Home Equity Loan FHA Title 1 Home Improvement Loan Local banks may offer different options Ownership Models Financing Options
How - Process for the Customer Energy Audit Site Assessment Contract with Installer Installation paperwork (permits, interconnection, rebates) Installation paperwork reviewed & approved Installation scheduled Inspector( s) sign off on system Installer closes out installation paperwork System is turned on Sign up with an SREC aggregator Apply for tax credits LGHA Design Review
