Do LED lamps ever go bad?What's the life expectancy of solar panels?
ED stands for light emitting diode, an electronic device which turns electric power into light with nearly perfect efficiency. When used in flashlight or othe battery powered lights, they will provide equal amounts of light for 00 times as long as ordinary incandescent light bulbs. Because of there very low power usage, led light are ideal for solar powered lighting systems. They are now made in every form and size, for DC or AC power, for homes, automobiles and outdoor lighting. Although they cost more, the savings from 20 year life expectancy and % power use mean savings of 95% over several years. sunsourcepower
LEDs last approximately 50,000 hours of operation, continuous or non-continuous, it doesn't matter. 50,000 hours. Solar panels will, theoretically, last until the end of time. The support structures will fail long before the panels themselves. Inverters, battery banks, op-amps, transformers, control boards, etc. will all fail long before a solar panel stops making juice.
