I got the idea from the <a href="http://loraham.org" class="">loraham.org</a> project. Remove the LED panel and insert the radio node. As in this example ( <a href="https://www.aliexpress.com/item/32856574541.html" class="">https://www.aliexpress.com/item/32856574541.html</a> ), for $12 you get solar, charge circuit battery, "IP65 enclosure and physical mounting. It probably won’t have MPPT, but maybe that can be offset with an extra battery or software geared toward power efficiency. Some of these flood lights are junk, some are decent, YMMV.<div class=""><br class=""></div><div class="">!!Dean</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Jan 16, 2020, at 11:50 AM, <a href="mailto:samuk@disroot.org" class="">samuk@disroot.org</a> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="">Hi all <br class=""><br class="">I've been looking into solar a bit, in the process, I came across this MPPT: <a href="https://www.aliexpress.com/item/4000031728632.html" class="">https://www.aliexpress.com/item/4000031728632.html</a><br class=""><br class="">The 2.9v cutout should mean the battery lasts a reasonable timeframe.<br class=""><br class="">This is the list of bit's I'm going to test for a solar node: <br class=""><a href="https://my.aliexpress.com/wishlist/wish_list_product_list.htm?¤tGroupId=100000018985469&page=1" class="">https://my.aliexpress.com/wishlist/wish_list_product_list.htm?¤tGroupId=100000018985469&page=1</a><br class=""><br class="">It comes to around $70 per node.
