This is an amazing tool & failsafe if it works as described!
No solar yet, but I love this for manual backup when power is out. It will refill your pressure tanks and thus your entire home has water in a power outage. Adding solar is possible. https://simplepump.com/

I love mine. Have had it for about 6 years. Never one issue. Engineer 775 does some great work with them and also shows how to add solar. https://youtube.com/@engineer775
