❗ De simples panneaux solaires pour faire fonctionner une Tesla

Le post original

In a bold experiment blending DIY spirit with clean tech, a Tesla owner installed flexible solar panels across the roof of his Model 3 and connected them to a portable power station. The goal? To test whether he could achieve completely off-grid charging—without paying a cent for electricity. Surprisingly, the setup worked, showing visible energy gains from sunlight alone, although at a slower rate than traditional chargers. This experiment shines a light on the potential of solar charging for EVs, especially for short commutes, camping, or emergency use. While it’s not yet a practical daily solution for high-mileage drivers, it’s a glimpse of a future where cars generate their own power. As solar tech and battery storage advance, the dream of a truly self-sustaining electric vehicle edges closer to reality. #TeslaDIY #SolarEnergy #OffGridTech #CleanMobility #EcoInnovation

Le fact-check

❗ He’s not going to get very far! Looking at the photo and the size of a TESLA, it seems like this person installed around 3 to 3.5 square meters of solar panels. Based on typical solar panel efficiency, that would generate around 4 kWh after 8 hours of full sun exposure. Given that electric cars use about 14 kWh per 100 km, that’s only enough to drive about 20 km — and only at night, since the car would have spent all day charging. https://fr.automobiledimension.com/modele/tesla/model-3 https://www.kelwatt.fr/guide/panneaux-solaires/rendement-rentabilite We’re still a long way from a truly energy self-sufficient car. The Lightyear 1 — which was actually designed as a solar car — can go up to 75 km on solar power after 8 hours of charging. But it'll cost you a cool €200,000. https://www.autonews.fr/green/actualite/lightyear-one-jusqu-a-710-km-pour-la-voiture-electrique-solaire-99343
