Hello there!
I use Aurora app to create a 3D simulation of a year round of Solar production with different brands and different sizes, if you send me your bill I can even calculate how much would you save and how much cost-efficient will be in your area. .1 ETH per project.
Also can make your CA permit in AutoCAD with all the PV pages ready for printing/plotting in PDF format, this includes Line diagram, CAD drawing of the property from satellite view, placards and current specification certificates and fire rating A paperwork. .1 ETH per project.
