I’ve never found it easier to train new hires than with OpenSolar. I think it’s really changing the industry, and a lot of the other players, are struggling to play catch-up, and the support team is amazing. ### 1/5 — Doesn’t work at all *2023-07-22, version 2.11.4* Just shows blank white screen. ??? ### 1/5 — cant open app *2022-10-31, version 2.7.0* I get the see same issues others have mentioned, blank screen apart from “welcome to myenergy” !!!! ### 1/5 — Blank screen *2022-09-25, version 2.5.0* After logging in just get a blank screen which says “welcome to myenergy”. No other options. Same on website. ### 5/5 — Amazing *2022-06-15, version 2.21.0* Just want to say a massive thanks to the Open Solar team, (and Segen Solar for integration) for providing this unbelievable technology and software platform for FREE, I can’t believe it, THANKS so much, this will help small startup solar panel installers like us at switchsolarpv.co.uk to streamline our sales and marketing strategy and provide valuable information to our customers on the spot. (sorry had to add a link) ### 1/5 — Fails to login *2022-04-02, version 2.20.0* Shows the words: My Energy and that’s it. Nothing else. ### 5/5 — What I’ve been searching for! *2022-01-09* This app and platform is what exactly I’ve been wanting in a solar proposal tool! The ability to customize it to your liking and having the ability to sign contracts and order materials all in one app makes it super easy for my Solar sale reps to close more deals faster. The open API and new features being released helps me connect this to my other applications. The best way to experience the app and platform is to reach out to the support team and schedule a demo. ### 5/5 — Great app *2021-11-03* OpenSolar as a solar sales tool is fantastic, and the app is great for in field sales and project management. We use it exclusively. ### 1/5 — Can’t be used without an account *2021-08-05* Can’t be used without an account ### 5/5 — Great app - easy designs and beautiful proposals *2021-07-15* The OpenSolar app makes it really easy to generate accurate solar energy system designs and the proposals are just beautiful. Love that the proposals are interactive so customers can really explore and get comfortable with the purchase on their own. ## Frequently asked questions about OpenSolar ### What is OpenSolar?
