The CPUC insists it wants people to add batteries to solar systems to help the grid. But it just cut the compensation that households can earn by doing it.
Very few homeowners are going to want to pay even more for tracking. You’d also need more space to accommodate the swing of the array, and it also brings about more consideration for wind loads.
In principle I think it would be ideal to have an easily accessible rooftop with a rooftop terrace so the rooftop space is functionally usable. But then indeed the frames that hold the panels up high enough so you could sit under the panels as they move would have to be rock-solid and thus costly. But quite useful if they could flip 180° when there’s hail (and unconditionally at nighttime). I’m brainstorming… is that crazy talk? Is this something that’s so cost prohibitive that the costs could never be recovered? It obviously wouldn’t be a budget option but some people might be willing to pay more just to have the luxury of extra terrace space.
I’ve heard the down-to-earth lean budget approach is to have the panels on the ground because of the need to periodically quickly cover them up in hail storms and do various other maintenance tasks and adjustments. I don’t have ground space though.
Grid inefficiencies are still present with rooftop systems as well, as excess power is sent back to the grid.
IIUC, feeding the grid is more energy efficient than feeding batteries, which I assume is why you have an assumption of grid-feedback, correct? Alternatively, what about installing an extra big hot water tank so there is never unconsumed power?
Yes, a panel system like that would be very complex and costly, with little additional benefit. If it hails with the intensity to damage panels so often in a certain location, it’d probably be best to look at other generation alternatives.
A hot water tank is still essentially unconsumed power, and likely worse in a warm climate, as heat will leak causing your cooling system to work harder.
