This is a long answer. Depend on 1. Location.
2. Facing.
3. Surrounding Structures.
4. Roof Surface.
5. Your energy Consumption.
6. NV Energy Rate Increase.
We got a free estimation and found out according to the current rate it takes 15 years to recover the costs. If everything states the same. In reality, it might take less than that. The warranty is 25 years. |
