In Florida, most utilities use a 3-tiered interconnection standard. Each tier has its own size, insurance, and other interconnection requirements and considerations.
Tier 1 – 0 – 10 kW AC (11.6 kW DC) – Residential Tier, no requirement for AC disconnect or homeowners’ insurance in Investor-Owned Utilities (IOUs)
Tier 2 – 10-100 kW (carries insurance and interconnection requirements, including use and transformer size)
Tier 3 – 100-2000 kW (carries insurance and interconnection requirements, including use and transformer size)
IOUs include Duke Energy, Florida Power and Light, and TECO. Contact us to learn more about your business tariffs, rates, and resulting effective solar offset rates and ROI.
