I have a system that was installed in 2014 with 250kWh solar panels. Can remove the older panels that produce 5KW be upgraded to newer solar panels with higher wattage and keep my NEM agreement?

The roof itself may need replacement and need removal and re-installation of the panels: it’s important to have a new and high quality roof as well as high quality mounts and installation.

Any idea of the cost to clean solar panels yearly? Need to factor in all costs to this “ green energy “ considering it takes about 20 years to break even in the cost is it really worth it in the long run? When the panels last 20- 25 years?
