Solar electric systems receive $1.50 per DC watt for the first 8 kilowatts installed; solar thermal systems receive 50% of the first $5,000 in costs; energy storage receives $0.20 per watt-hour for the first 20 kilowatt-hours.

Energy efficiency services credit equals 35% of the first $10,000 in eligible costs per residence, with services including insulation, weatherization, HVAC upgrades, window improvements, and other measures recommended by a Home Performance Audit.

Requires all solar work to be completed by Mississippi State Board of Contractors-licensed contractors with National Board for Certified Energy Practitioners or equivalent certification; energy efficiency work requires MSBOC licensing and Building Performance Institute certification.

Credit declines by 10% annually beginning one year after enactment and expires after 10 years; any credit exceeding tax liability is refunded by the Department of Revenue within 180 days; credit becomes effective July 1, 2018.
