The world's first solar-rechargeable tuner is the TC-1S from TASCAM. The TC-1S charges its battery from a bank of solar cells on the front panel in just 25 minutes, and a USB input is also available for quick-charging. From a full charge, the battery works for six hours of constant use and seven years of standby charge in a dark place. It's wrapped in a shock-proof silicone cover that's available in six colors and keeps the unit protected. The world's first solar-rechargeable tuner is the TC-1S from TASCAM.
