Place your tongue tip near the roof of your mouth behind your top teeth. Push air through the narrow gap. No voicing.

Americans pronounce solar as SOH-ler (/ˈsoʊlər/). Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "He put solar panels on his roof to generate electricity" or "The milky way is the galaxy that contains our solar system" — more examples below.
Record yourself saying "solar" and play it back. The mic stays on your device — nothing's uploaded.

Place the tip of your tongue against the alveolar ridge just behind your top front teeth, the same contact point as /t/, /d/, and /n/. The difference is what happens to the air: for /l/, you let it flow continuously around the <em>sides</em> of the tongue (that's why /l/ is called a lateral). Turn your voice on the whole time. Lips stay relaxed, no rounding or flaring. For the Dark L variant at the end of a syllable, also pull the back of the tongue up and back toward the soft palate.

Relax your mouth and lift the tongue back and up. Keep the lips neutral.

The textbook way isn't wrong — it's just not how anyone actually says it.
Stress falls on the first syllable, not the others. Stretch SOH — keep everything else short and quick.
Americans use a relaxed retroflex R — the tongue curls back rather than rolling. The R is one continuous sound with the vowel before it, not two separate sounds.
