I am doing this rooftop assembly PV for a nameplate capacity of 10 KW , but I always get these errors mentioned in the title, any idea why?
I am all new to this SAM software so please any help is much appreciated.

Thank you
For the Residential and Commercial financial model, a negative NPV indicates that the electricity bill savings are less than the project costs over the analysis period. To make the project economically viable you can try:
Decreasing the installation and/or operating costs.
Increasing the load on the Electricity Load page.
Increasing the energy rates on the Electricity Rates page.
Thank you very much for your answer solved my problem ! , I am also wondering how to include back tracking with this system as I don't see any box to tick for that matter.
