No — and here's the engineering reality: solar today functions almost exactly like it will in 10 years. Panels will get slightly more efficient (they always do), but the difference waiting makes is tiny, while the money lost to your utility every month is real and gone forever. A panel installed today produces power for 25-30+ years either way.
The thing that IS changing fast is the incentive landscape — and it's changing in the wrong direction for waiters. The homeowner federal credit is already gone. The corporate credit programs expire around 2027. Rebate funds like SDCP's are being drawn down right now. Waiting for better panels means paying more for the same sun.
