Overview
Comprehensive Service Overview:
Expll Technologies delivers turnkey solar farm solutions for utilities, IPPs, and corporations. Our end-to-end approach combines cutting-edge technology with financial rigor to maximize your project’s lifetime value:
Site Selection: Advanced GIS tools analyze irradiation, topography, and grid proximity to identify optimal locations. Our team secures land leases with community benefit clauses.
Engineering: We design with bifacial modules + single-axis trackers (yield boost up to 27% vs. fixed-tilt), using PVsyst simulations validated by 15-year historical weather data.
Grid Integration: All plants include hybrid inverters (1,500V DC) and SCADA systems pre-configured for IEEE 1547-2018 compliance.
Financing Support: We prepare bankable feasibility studies with 20-year PPA modeling (LCOE accuracy ±3%) and connect clients with our vetted investor network.
