Hospital distributed photovoltaic system component prices

The investment cost of distributed PV consists of the cost of PV modules, balancing system cost (BOS), and soft cost. The cost of PV modules is determined by raw material costs, notably silicon costs, cell processing/manufacturing costs and module assembly costs .

The costs associated with integrating PV into bulk power and distribution systems are both commonly referred to as “grid integration” costs; however, in general, modeling the cost of each of these systems involves distinct challenges.

The cost of PV modules is determined by raw material costs, notably silicon costs, cell processing/manufacturing costs and module assembly costs . At present, for conventional distributed PV projects, the cost of investment is roughly 6.5 yuan/W. Fig. 8 gives a detailed breakdown of the cost of investment.

The total cost over the service life of the system is amortized to give a levelized cost per year. In the PV System Cost Model (PVSCM), the owner's overnight capital expense (cash cost) for an installed PV system is divided into eight categories, which are the same for the utility-scale, commercial, and residential PV market segments:

Except 100% grid-connected mode, the IRR of distributed PV power plants in three areas is higher than 8% which has shown good economic benefits. As subsidies continue to fall, the technology and cost performance of distributed photovoltaic (PV) determines the progress of its grid parity.

The initial costs of PV–diesel–battery and diesel–battery systems are $2,418 and $879, respectively. Net present cost of PV system is $13,523 and diesel system is $20,515. Results show that hybrid PV–diesel–battery energy system is more economical and environmentally friendly energy system for remote healthcare centre.
