PERFORMANCE
15 SolEngCo - The Solar Engineering Company
The most profitable CSP Project
Is based on a proficiently performed site selection.
Is based on a basic design carefully concerning the
local manufacturing.
Is based on an analyse of conditions of PPA (FiT).
Optimum layout of the solar field
must be carefully evaluated based on the geographic
latitude, the available land of the individual site, its
irradiation profile and the relative cost of the
components.
