I still use the SolarABC’s reference map, pulls the ASHRAE data. Good for the US only.
https://energyresearch.ucf.edu/solar-certification/solar-reference-map/ Not record lows, but I have used this for years as the design low temperature for string sizing. They claim the data is outdated, but with climate change I feel safe that the Extreme minimum temperature is likely to only go up 😉 -- Danny Young NABCEP PV Installation Professional #031508-90 VP of Engineering Solar Energy Solutions Lexington | Louisville | Bloomington | Cincinnati | Evansville | Indianapolis 513-448-5176 (mobile) 877-312-7456 (Main Office) da...@sesre.com<mailto:da...@sesre.com> From: RE-wrenches <re-wrenches-boun...@lists.re-wrenches.org> On Behalf Of Christopher Warfel via RE-wrenches Sent: Tuesday, August 22, 2023 1:47 PM To: re-wrenches@lists.re-wrenches.org Cc: Christopher Warfel <cwar...@entech-engineering.com> Subject: Re: [RE-wrenches] Record Low Caution: This email originated from outside SES.

We are designing a project that has very different temperature characteristics than we are used to. Ashrae.org was recommended as a source. Does anyone know where on the site to look?
