<H2>Summary</H2>
<p>Since 2003 the bivy site at the stone bridge has had a number of solar panels and a car battery, which are mainly used for charging lamp battery packs, drill and AA/AAA batteries (and phones). Much bigger flexi solar panels arrived in 2007 and a second, larger, battery around the same time (2009?).</p>
<p>Since 2003 the bivy site at the stone bridge has had a number of solar panels
and a car battery, which are mainly used for charging lamp battery packs, drill
and AA/AAA batteries (and phones). Much bigger flexi solar panels arrived in 2007
and a second, larger, battery around the same time.</p>
<p>The system is actually two independent systems running in parallel.
<p>In 2018 two new PV panels were bought.
These <a href="https://www.jinkosolar.com/ftp/EN-Eagles-270PP-60_rev2014-1.pdf">Jinko JKM270PP-60</a>
beasts are 255W (peak), ~16% efficient and weigh 19kg each. They are glass-fronted, aluminium-framed, and measure 1650 x 992 x 40mm.
The intention is that they will be installed at Steinbruckhohle top camp
and that the light-weight panels already there will be transferred to the Organhohle
bivvy camp. The rest of this text describes the situation
in 2017 before these Jinkos were bought. Also new in 2018 is a new set of 12V sockets (car type). This page will be updated when they have been installed.
<p>The system (in 2017) was two independent systems running in parallel.
<ul>
<li>The Big system uses the three big solar cells on the big wooden frame the big battery and the cable with the (hopfully) obvious connectors on it</li>
<li>The Little system uses the four small aluminium framed solar cells and the smaller battery and the cable with the banana plugs on one end</li>
