What it Costs
The average 5-kW system costs $22,000 with system design, equipment, and installation2. With financing, the Incentive Rebate, and the Federal Tax Credit, this system can cost even less. Here’s how:
5% off the total cost with the Vermont Small Scale Renewable Energy Incentive Program: This standout “Incentive Program” offers Vermont solar PV and hot water customers a cash rebate of 25 cents per watt of solar capacity (energy generated by the system) installed. Your installer will handle the paperwork, and simply deduct this amount from the overall price of the system. At the current 25 cents per Watt rebate, that is $1,250 off the total cost3.
Another 30% off the total cost with the Federal Tax Credit for solar energy systems: The federal government offers a 30% Income Tax Credit for solar PV and hot water systems to eligible homeowners and businesses with taxable income. This is equal to $6,225, and is in addition to the Incentive Rebate (valid until Dec, 2016).
Then it’s free: After the system is paid off, your electricity will be 90-100% free!
Once I am no longer renting solar is an option I would like to pursue.
