<H2>Summary</H2>
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 homemade battery packs, drill and AA/AAA batteries. This document is unfortunately written from memory, so someone with some electronics knowledge and a multimeter should set things up, so they can spot the errors and omissions in this document.
<p>Martins bodged together Tupperware box, is a retro fit to Earls original system. The Tupperware box controls the charging and discharging of an external lead acid battery. Whereas before, Earls box did not do this and thus risked cooking the battery or completely flattening it. This means that the labels on the Earls well constructed box no longer apply. It may well be a good idea to relabel things.

<p>The system can be made moderately weather proof, but in very windy or wet weather, it should be bought into the relative safety of the stone bridge.

<p>Since 2014, we've found that this current webpage bears no resemblance to what is actually up at topcamp. The following is still updates in progress, notable additions are in bold.</p>

The below is still out of date, but I got shouted at when I said that I was about to change it...
<H2>Setup of solar panels</H2>
Four 12V solar panels are mounted on an aluminium frame, which has been put on some flat limestone, slightly downhill and to the right from the stone bridge. The solar panels are waterproof, but are liable to be being blown over and damaged, hence large rocks must be used to keep it in place. The panels should be orientated pointing into the sun, without any shadows on them. Looking at the panels you can see the individual ~0.6V photo-arrays, each one not getting sunlight reduces the voltage output of the panel. There is also a fifth panel that can be propped against a rock in good weather.
