Solar Taxes And Rebates

Motivating residents to consider installing solar panels can often be a challenge due to prohibitive initial costs. States can help by issuing rebates and tax breaks to their residents. Massachusetts has a tax credit of $1000 or less or no state tax. The state has no overarching rebate program, but local rebates are available to many citizens who wish to purchase private solar. Massachusetts residents have the ability to apply a 100% property tax exemption for the installation of solar panels, which is better than almost all other states. There is currently a 100% sales tax exemption in place for the purchase of solar at a place of residence.

State Level Initiatives

Whether a customer is able to easily purchase electricity options with renewable fuel types is somewhat determined by legislation at the state level. Renewable Portfolio Standards (RPS) encourage or require electric suppliers to generate a percentage of their electricity from renewable energy. The state of Massachusetts makes it necessary for electric providers to produce between 16-24% of their output from renewable fuel sources. In addition, the state has a low income solar program in place to encourage low income households to install solar panels.
