Solar power in Worcester, Massachusetts

National Grid offer an SREC and net metering program to their customers going solar in Worcester. Net metering credits each kWh of unused solar generation at the retail rate for power. 100kWh exported to the grid would eliminate the cost of 100 kWh drawn from the grid at night or on a cloudy day for example. If in a billing month more energy has been sent to the grid than drawn credit is still provided at 1 for 1 to future bills indefinitely. At the end of a 12 month billing cycle remaining credit will be deposited into your account.

Power providers in Massachusetts must source a certain percentage of their energy from rooftop solar creating a market for Solar Renewable Energy Certificates (SRECs). If utilities fail to meet their guidelines they are fined heavily. Each SREC is proof of 1mWh of energy production priced at about $270. A standard 5kW system usually produces about 6mWh per year resulting in a check from national grid of about $1,350. Since the fines for not producing enough SRECs is set to reduce by about $15 per year returns will reduce slightly however, over the life of a 5kW system this would put about $14,000 in your account.

Massachusetts offers a state tax credit of $1,000 or 15% of the total system cost. After deducting the state tax credit and any other rebates 30% of the remaining cost can be claimed as a deduction to federal taxes. The federal solar tax credit has no size limit and gives you the option to use it over several years or all in one year if you wish. Financial incentives like these are very rare to still see and should not be taken for granted.
