SOLAR SYSTEM DESIGN & PPRODUCTION

=  Size: 24 Panels; 5.88 kW DC (~350 Volts, 16.8 Amps)

=  Annual Production: 99% of 6,376 kWh Usage (266 kWh/Panel)

=  Production Over 20 Year Lease: 127,520 kWh

SOLAR SYSTEM SAVINGS 20-YEAR LEASE

=  $44,041; $29,906 + $14,135 assuming a 4.8% annual rate increase

ELECTRIC UTILITY COSTS WITHOUT SOLAR

=  Monthly Payment $113.36 @ 21.1¢/kWh Avg. (11/25/13)

=  Estimated Annual Increase: 4.8%

=  Total Costs (Over 20 Year Lease): $44,041

SOLAR LEASE COSTS (20-Year Custom Plan Option)

=  SolarCity Price: 17.3¢/kWh

=  Annual Increase:  None

=  Initial Payment:    None

=  NY State Tax Credit: $5,000 (-4.1¢/kWh)

=  Monthly Payment $88

=  Total 20-yr Savings: $25,167

GFX SAVINGS (25 to43% of Solar Savings)

=  1^ST Year of 20-Year Lease: $212-$372 (Table B)

=  Total GFX-Savings: $6,244 to $10,956 (20 Year Lease)

=  GFX Cost: $580

=  Estimated Oil Costs: $4.00 /Gal. + 4.8% Annual Increase

Estimated Residential Savings (GFX Model S3-60)
