The cost of solar PV technology also dropped dramatically.

因为太阳光伏发电的技术成本也面临着同样的状况。

Where there is no public power grid, the PV systems currently operate cost-effectively, due to their low operating costs.

在没有公用电网的情况下，由于系统的低运营成本，就它们当前的表现来看这一系统的成本是可以接受的。

"Also, light levels are currently increasing year on year and so it would be reasonable that the unit cost of PV generation will decrease in the future, " he said.

While the low water use and cost of PV will appeal in the desert kingdom, the fact that solar will be displacing power generated from oil means that even CSP based power will produce cost reductions.
