Francois Dion<p>The load was a cooler style 12V refrigerator (with a compressor). Each day I took out an item and put in a room temperature item (bottled water, juice etc). During the same period, I consumed 475Ah, a deficit of about 3 amps or 36 watts over 7 days. Not bad especially since the past week was unusually hot, even with the storm cooling things a little.</p><p><a href="https://mastodon.online/tags/solar" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>solar</span></a> <a href="https://mastodon.online/tags/pv" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>pv</span></a> <a href="https://mastodon.online/tags/camping" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>camping</span></a> <a href="https://mastodon.online/tags/overland" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>overland</span></a> <a href="https://mastodon.online/tags/battery" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>battery</span></a> <a href="https://mastodon.online/tags/solarpanel" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>solarpanel</span></a> <a href="https://mastodon.online/tags/Pwm" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Pwm</span></a></p>
Francois Dion<p>After one full week with the solar panel on my vehicle (Tuesday 8am to. Tuesday 8am), I've accumulated 472Ah which is ok I guess for a 200 watts panel that is just laying flat above the bed. I just drove and parked as usual, so a good bit of shade. Weather was a mix of sunny, cloudy and even storm (that took out some trees in the area).

Ch M[ae][iy]e?r 🇪🇺 🖤 🤍<p>Eine <a href="https://digitalcourage.social/tags/Physik" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Physik</span></a> Frage:<br>Dimmbare LEDs werden üblicherweise per <a href="https://digitalcourage.social/tags/PWM" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PWM</span></a> geregelt, Pulsweitenmodulation. Je länger die Pausen im Puls, desto dunkler erscheint die LED, kürzere Dunkelzeiten entsprechen einem helleren Sinneseindruck. Dabei wird die Trägheit des Auges ausgenutzt. Soweit, so logisch.</p><p>Beim Fahrrad-LED-Scheinwerfer ist es ähnlich. Wenn man langsam fährt, dann blitzt die Lampe einmal kurz auf, danach folgt eine Dunkelphase.<br>Wenn man jetzt schneller fährt, dann erscheint die LED als dauerleuchtend.</p><p>Mir ist aber noch nie aufgefallen, dass bei schnellerer Fahrt die Lampe heller erscheint, als bei langsamer Fahrt.<br>Woran liegt das?</p>
