Minimizing the cost per kilowatt-hour for the electric energy provided or maximizing ROI is the main objective of solar power plant design and optimization. Thus, it can be reasonable to accept higher investment cost if, in return, the performance and output rise significantly, or the operating expenses decrease. It may also be clever to sacrifice a little fraction of efficiency if investment costs are then reduced significantly, and LCoE is reduced. Always, it is important to take a holistic approach. To develop an optimal system or product, both, technology, and cost must be taken into consideration. Therefore, performing a techno-economic analysis and optimization is an important part of any successful development and improvement at sbp sonne.
