How net metering works

When panels produce more than you use, surplus energy flows to the grid. Your utility credits your account — at retail, avoided-cost, or buyback rates depending on policy.

Solar installation costs in New Hampshire reflect local labor rates, permit fees, and utility interconnection rules. A typical 6 kW system runs $14,140–$24,990 before the 30% federal tax credit, with net cost around $9,900–$17,490.

  • Daytime surplus → bill credits
  • Evening usage → draw from credits
