System Sizing
Surplus Energy is evaluated to store in the Energy Storage for Increasing Economic Viability.
Results Verification:
Solar Energy System
After completing our modelling and analysis of the renewable system, we collaborated with our industry representatives to verify our findings to ensure we were on the right track. Our selections and area consideration was similar as those identified in their independent study.
System data shared was compared and found to be within an acceptable range, and thus we decided to move ahead with the next stage which was the storage selection and sizing , and the economic analysis of our project.
