Solar panels can cost about $20,000, but some homeowners say they’re worth the investment as energy prices go up

This fall, as John Y.K. Lee realized his electric bill had doubled, he finally decided to invest in solar panels.

For years, the neurosurgeon had thought about installing them on his family’s Havertown, Pennsylvania, home. But he sped up his timeline in the past year.

“All of a sudden there is all this perturbance in the energy market,” said Lee, 50. “I really started getting interested in our energy situation and future. I started investigating what I could do.”
