@EdLudlow Fix it ASAP otherwise the crack might expand due to temperature differences at night. I have been through this. Simple $10 fix turned into $thousands.
@magali_c My family home in Guj had solar power. Govt gave 50% subsidy (!!!). Total cost after subsidy was 50k for 4KW system. The system reduced our electricity bill by 75%. It would pay for itself in few years.
We lost all panels few months back due to cyclone Tauktae.
