I just read the smartflower has a self cleaning feature. It self cleans the panels twice per day.
2.5kw max output.
extimated 6,500kwh/yr
The base Smartflower itself is $39,950 plus installation and shipping charges, and the Smartflower Plus is $65,500 plus shipping and installation. Installation costs vary by difficulty and complexity of each setup, ranging from roughly $3,000 to $7,000
Yea I wouldn't use it just cuz they have different levels of panels (ignoring the price)
they should have some hydraulic lifters per panel to make them all even
definitely need lifetime warranty for that price
