Florida and most dry &#x2F; sunny states having little to no solar panels is pretty damn wild.<p>I know in florida you have janky laws stopping you, but below 10kw it&#x27;s still relatively easy.<p>I have a friend who installed &lt;10kw of solar panels and they&#x27;re now 97% off-grid in hot, wet florida weather with an old low-seer AC, single-pane windows and poor roof insulation which is roughly 60% of the energy usage.<p>The reason they got it is actually not to save money or anything, but to have power when grid goes down after hurricanes.

What&#x27;s the big deal with having a whole liquid cooled workstation, and why is it important information for me to know what this dude&#x27;s hardware is? And seriously, is there something about the rig that is necessary to chew through a dataset with a few million rows?

Would be kinda interesting to see a histogram of the azimuths and&#x2F;or tilt angles.<p>In my native Netherlands I&#x27;d guess to see that peaking at ~south at say 15-30 degrees, with some lower peaks at east&#x2F;west combos.<p>Curious to see what it would be in this dataset.

Pretty cool, although the heatmaps have a little of the &quot;this is just a population density map&quot; effect. <a href="https:&#x2F;&#x2F;xkcd.com&#x2F;1138&#x2F;" rel="nofollow">https:&#x2F;&#x2F;xkcd.com&#x2F;1138&#x2F;</a><p>It would be cool to modify them to be per-capita, although I imagine adjusting arbitrary hexes for population density would be a real challenge.

It&#x27;d be nice if it described up front what kind of information is available per panel.<p>For that matter, I&#x27;d be interested in details of how &quot;a team of researchers including alumni from NOAA, NASA and the USGS&quot; (from the previous article) actually collected the data.

To put this in perspective, China installs around 3x that every single day <a href="https:&#x2F;&#x2F;reneweconomy.com.au&#x2F;just-staggering-china-installs-100-solar-panels-a-second-as-total-pv-capacity-tops-1-terawatt&#x2F;" rel="nofollow">https:&#x2F;&#x2F;reneweconomy.com.au&#x2F;just-staggering-china-installs-1...</a>

look how cheap now, it&#x27;s crazy<p><a href="https:&#x2F;&#x2F;www.aliexpress.us&#x2F;item&#x2F;3256809986804138.html" rel="nofollow">https:&#x2F;&#x2F;www.aliexpress.us&#x2F;item&#x2F;3256809986804138.html</a><p>I&#x27;m old enough to remember Carter putting them on WhiteHouse roof and they were thousands of dollars then (and less efficient)
