Solar powered one transistor Pleiades power amplifier


It is possible with just 8mA current consumption at 12V to have world class sound quality.


An example is the Pleiades 2N3053 - Philips AD5046N combination. Operation is in class A ie electrons flowing all the time. See relevant euroelectron post.


If it is made in a box a small solar panel could be on top. Extreme caution should be exercised in the choice or design of the battery charging circuit for safety. And of course a fuse should alway be in series with battery.


The amplifier can be ready anytime charged even under ambient light conditions.  This is a bit unlikely though. As it sounds so nice it may be switched on for most part of a day.
