Solar Panels on Vehicles Can Offset Energy Needs

A European consortium including TNO, Fraunhofer ISE, Sono Motors, and others determined vehicle-integrated photovoltaics can significantly reduce energy consumption. The SolarMoves project analyzed data from 23 vehicle types—from cars to trucks—collecting measurements from 1.3 million kilometers driven. Researchers combined this data with meteorological information from Amsterdam and Madrid to model energy production.

The team calculates a passenger car in central Europe with ample roof space, like an SUV, could generate up to 55% of its energy needs. In southern Europe, this figure rises to roughly 80%. Electric trucks see a potential range extension of up to 15% with this technology.

The study projects that equipping all new vehicles from 2024 to 2030 with VIPV could lower European grid demand by 15.6 terawatt-hours by 2030. However, the consortium notes the actual cost of VIPV remains unspecified, hindering immediate widespread adoption. They advocate for including VIPV in standard vehicle testing procedures to incentivize its use and develop supportive policies.
