Replaced the 10 yr old 5W polycrystalline solar panel (L) that was putting out less than 300 mA (originally 480mA) into a 7Ah AGM bettery powering the beacon (barely). Upgraded to a new 100W monocrystalline panel (R) that puts out almost 4 Amps to a deep cycle marine battery to provide power to beacon and other projects. My beacon uses approximately 350mA on full duty cycle.
Beacon Maintenance: cleaned out cooling fan, replaced pico-keyer D cells (average lifespan ~2 years), checked all connections, cables, and breakers.
Here’s to another 5 years!
