Hi All,
I have a few questions about solar and would like to know the answers to the following:
1) If one must have distance between the home and the panels, (can't do roof mounted) Which is better longer AC or longer DC run ?
In other words keep the distance between panels and inverter short and a longer AC, OR
Have the distance between the panels and the inverter longer and place the inverter on the house wall
2) For a larger system 10Kw - 20Kw: Which is better micro inverters per panel or a larger Inverter?
3) When using micro inverters per panel, how does one charge the Battery backup? Convert AC back to DC to charge the battery? Seems a waste (due to energy loss during conversion)
Does this then imply micro inverters are best when no battery backup, thus using net metering. Pushing to the Grid when making and pulling from grid when demand exceeds generation
4) Can one have a single 20 kW panel setup with 20 kW battery backup, but then split this into 10 kW + 5 kW + 5 kW inverters and use a single generation for multiple supplies? In other words have a single panel setup and supply 3 houses in a small neighborhood
5) If wanting to (walk, crawl run,) grow over time mainly to break down the up front costs. Can one start with a 10 kW Inverter and then slowly add panels and batteries until one reaches the 10 kW all around (panels, battery and inverter) ?
Thanks in advance (sorry if this should have been individual posts)
