The City Walls and Towers of Luzern - and the llamas with power

Not wanting our August marriage getaway to end quite yet, we stopped in Luzern on our way home, and climbed a few of the city walls' towers, for our first time. 
Please note that the llamas of Luzern have solar panels for their electrical needs. What do you think they use the solar power for? Under-floor heating? Warm water for their showers? Their answering machine? Or maybe a mosquito zapper? (see last photo)
