Gasoline used in my car's life (215,000 miles so far) - 25,000 kg. Lithium used in a full electric EV - 10 kg. One is much less than the other. Steel in both kinds of cars - about a ton each.

Electricity for EV to drive 215,000 miles in 22 years (my car's age) - about 72,000 kWh. US solar capacity factor - 24.4% (actual average output divided by rated panel capacity). Average power needed to produce that much power in 22 years: 372 Watts. Rated panel capacity needed: 1.52 KW.

Output per panel: 550W from largest US manufacturer rated at 585W but allowing for power loss as the panel ages. So you need about 3 panels. Panel Mass 34.4 kg x 3 = 103.2 kg. Much less than the car, and 250 times less than ICE gasoline needed.

So there aren't zero side effects, but a lot less.
