![]() How long do solar garden lights lastĪny device will last as long as it’s weakest component and solar lights are no exception. Typical solar cell output voltage is 1.5V and the l.e.d.s require 1.2V. The better quality solar lights have a solar cell with a higher capacity, say, 600mA to 800mA, and these will perform much better in less than full sunlight. The current limiter is hardly necessary as the solar cell output is very low at between 100mA to 400mA, which means a solar charger isn’t needed.ġ00mA is more than enough to charge the battery. The blocking diode stops current from the battery from feeding back into the solar cell at night-time. ![]() Simple circuit board with blocking diode, current limiter and l.e.d. ![]() There are many types of solar garden lights but they all work in the same way and contain the same basic components: What’s inside a solar light and how does it work? ![]()
