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

Net Metering!!

Receive 200 kWh credit (in $)

Why - Massachusetts Residential Electricity Prices

35,00 30,00 25,00 20,00 15,00 10,00 5,00 0,00

Why - Solar Incentives in Massachusetts

High electricity prices + Reduced Solar PV Costs + Numerous Incentives = Economical solar projects Incentives

Tax Incentives: Federal (30%) State (15% up to $1,000) Rebates from MassCEC: Typically $2k - $4k Net Metering SREC Sales Low/No money down options

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?

• 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 http://energy.ltgovernors.com/solar-energy-pv-systems-self-generation-make-your-own-power.html

How - Ownership

Ownership Models
