Solar PVs to Charge EVs in Auckland: Potential for a Community Based Approach

Abstract

Auckland enjoys 2050 hours of sunshine per year, yet, in the absence of supportive government policies, the solar resource has not been harnessed to its full potential. Auckland Council is committed to a sustainable pathway in mobility and energy consumption, including aiming at 40-50% EV fleet and PV installations powering an equivalent of over 176 500 homes by 2040. The general challenge of combining solar PV with EV investments for most Aucklanders is the mismatched timing of solar output (day time) and vehicle availability for home charging (night time). Technically this could be overcome by smart meters for PV installations at residential buildings and charging points at commercial buildings or work places; with differences between EV load and PV output accounted for. To evaluate the potential for EVs charged by PVs we have used high quality LiDAR data to assess the solar potential in residential and commercial buildings in Auckland and linked that to recent census data on mobility in Auckland. We present the idea of a community based organisation of charging EVs with solar power, whether the solar panels are installed at residential homes or the commercial building where the charging takes place, or both. With this community organised approach - based on people working for the same company, in the same building, or simply using the same car park - some investment and transaction costs, as well as risk, can be shared, battery storage costs avoided and the learned know-how transmitted onwards transforming Auckland towards it’s sustainability targets.
