EV Charging
Charging Your EV With Solar: A Real Cost Comparison
How big is the actual cost gap between a gasoline car, a grid-charged EV, and a solar-charged EV per 100 km?

The most common question about EV ownership is how much charging actually saves. The numbers are stark: a gasoline car costs roughly ₺250 per 100 km, while an EV charged from the grid brings that down to ₺85. Charge it with solar power and the figure drops to ₺18 — with solar plus battery, as low as ₺12. That's roughly a 70% cost reduction compared to gasoline.
TFTC Solar packages this savings into two ready-made bundles. The first combines a 5 kWp rooftop solar system, 5 kWh of storage, and a 22 kW Sirius AC Charger EV charging station for a total of ₺271,670. For households with higher consumption or that need to charge more than one vehicle a day, a larger bundle steps up to 10 kWp of panels, 10 kWh of storage (two 5 kWh battery modules), and the same 22 kW charging station for ₺404,970.
The logic is simple: daytime solar production is routed first to the home, then to the battery, then directly to the vehicle as needed. Grid draw drops to a minimum, so both the electricity bill and the "fuel" cost fall at the same time.
