JWST isn’t in Earth’s shadow - it orbits around L2 (approximately perpendicular to the Sun-Earth axis) at a radius comparable to the Earth-Moon distance. JWST has a huge solar array used to power the electronics on-board. Even if it was stationary at L2, Earth wouldn’t completely shield it from the Sun - the point is too far from Earth/the Sun so large for it to. There is a nice animation on https://webb.nasa.gov/content/about/orbit.html https://webb.nasa.gov/content/about/orbit.html
