A separate electrical permit is also required and is reviewed under the National Electrical Code as adopted by the NH State Building Code. Nashua's Permit Fee Schedule sets the residential building-permit fee at $0.18 per square foot of area affected, plus a $35 filing fee and a $25 Land Use review fee; commercial solar energy systems are billed at $0.65 per $100 of construction cost.

Some RestrictionsHOA Restrictions
New Hampshire does NOT have a statewide solar-access override statute comparable to Colorado, Florida, Texas, or California. The state's solar statutes — RSA 477:49, RSA 477:50, and RSA 477:51 — authorize VOLUNTARY solar skyspace easements that must be negotiated and recorded by the property owners involved, but they do NOT void HOA covenants that restrict solar installations. A Nashua HOA whose declaration or rules prohibit or limit rooftop or ground-mount solar can generally enforce those restrictions absent a separately negotiated solar skyspace easement. Disputes are resolved in Hillsborough County Superior Court under contract and condominium-association law.
