I am looking for a way to install light in a shed, approx 6m2.
Have 5m 2W/m LED strip that will be stapled to rafters, they are exposed.
For the battery, I am thinking convenient Ryobi set of **broken link removed** that sells here rather inexpensively. Battery would be pernamently in charger, stepped down to 12V for LED strip.
Charger's DC adapter would be removed and replaced with solar panel + boost regulator.
Expecting one inconvenience, charger is too fast, charging 36Wh battery in 40min, that is 54W, so solar panel would need to be about that size as well, which seems rather ineffective, since the battery can be topped during entire daylight I would prefer if it took 4-6hrs to recharge that battery. Not sure how difficult would it be to fiddle with chargers internals to slow it down.
