Overcoming Policy Barriers For Rooftop Solar-PV In Hawaii: No Export Islanded Nano-Grid w-Lifestyle Behavioral Changes

Location: 203AB

Aim/Objective: Residential rooftop solar-PV market on Oahu has dropped by 84% since peaking in 2013 with 14K installs because the new policies and programs have created economic barriers to sustain growth and continued deployment. This trend can be reversed with significant economic saving through no export islanded nano-grid operation and everyday lifestyle behavioral changes, achieving and sustaining 100% renewable energy for maximum economic savings.

Methods: Properly optimized hardware and control system equipment for solar energy generation with multiple renewable energy storage and home renewable energy management system and individual learning to be renewable energy conservation minded for the required everyday lifestyle behavioral changes.

Results: Since April 2017 we have achieved islanded nano-grid mode operation with no export using grid-connection as back-up to charge the multi-storage batteries on rainy/cloudy days. After identifying the top 7 energy demand household appliances, lifestyle behavioral changes was required to reduce grid-buy from 48kWh/day to 0.3kWh/day resulting in a yearly electricity cost savings of $4,184/year and renewable energy system pay back of 3.2 years. Today the new policies/programs for residential rooftop solar on Oahu has reduced export credit rate to $0.10/kWh hindering deployment and growth. Therefore we will present our learning over the past 20 months with ideas for new policies to reverse both the utility Duck Curve and the install decline in order to sustain continued deployment of residential rooftop solar-PV and achieve 100% residential renewable energy today by first achieving Islanded Nano-grids (individulal dwellings/structures) then Micro-grids (communities) followed by Milli-grids (town/city) and finally Macro-grids (county) .

Conclusion: We achieved islanded nano-grid operation for residential Hawaii using grid-connection for back-up to charge the multi-storage batteries on rainy/cloudy days. Besides the proper renewable energy equipment each person must learn to be renewable energy conservation minded for everyday lifestyle behavioral changes to sustain 100% renewable energy. New policies and programs are also needed to reverse the decline in rooftop solar-PV deployment and eliminate the utility Duck Curve.
