Solar power for your business needs

Review of STEG bills, contracted demand, operating hours and available load profiles. Comparison of PV scenarios and, where relevant, battery storage, taking account of the business’s operational needs.

Review of proposed rooftops, carports or land, access, existing uses and grid connection constraints. Identification of the land and structural checks required with the relevant specialists.

Layout, equipment selection and PVsyst/PVGIS simulations. Analysis of energy yield, losses and degradation; comparison of expected generation with the business’s load profile.

Techno-economic and financial study covering investment, operating costs, expected bill savings, financing and sensitivities. Tariff, consumption and generation assumptions are stated explicitly. Any surplus generation is assessed under the proposed arrangement and applicable conditions.

Consolidation of technical and economic assumptions, comparison of financing options and preparation of the financing package. Support for discussions with financing institutions, which retain responsibility for lending decisions.

Layout and wiring drawings, string sizing, DC cable and protection sizing, voltage-drop calculations and bills of materials suited to the installation.

LV/MV diagrams, AC cables and protection, transformers and substations where required. Consideration of the existing network, earthing, metering and supervisory interfaces.

Module arrangement, assembly drawings and interfaces with supports. Roof capacity checks, structural calculations and civil works are defined with the relevant specialists according to site conditions.

Review of equipment and design against project and grid connection requirements. Preparation of supporting documentation and tracking of deviations; independent inspections and official approvals are separate activities.

Short-circuit calculations, discrimination curves and LV/MV settings. Coordination with the industrial site’s protection systems and assessment of interface protection, according to the selected arrangement.

Technical specifications, tendering and technical and commercial bid evaluation. Clarification of supply scope, warranties, expected performance and constraints when working at an operating site.

Document review, schedule and quality monitoring, site visits and punch-list management within the agreed scope. Coordination of grid connection discussions and interventions with the operator to account for business continuity.

Support for testing and acceptance, punch-list follow-up and metering verification. Preparation of generation and self-consumption monitoring to compare actual results with study assumptions.

Definition of generation monitoring, alarms and performance indicators. Maintenance, warranties and cleaning requirements depend on equipment and site conditions; the scope is specified in the contract.
