Solar energy systems
DMC provides end-to-end solar engineering: site assessment and feasibility from twelve months of utility data, structural and shading analysis, capacity sizing and technology selection, detailed 2D/3D design in PVsyst, AutoCAD or Helioscope, string configuration and single-line diagrams, lightning and surge protection, mounting structures for local wind and seismic loading, bills of quantities, yield simulation and construction supervision.
We provide end-to-end solar engineering: custom system design paired with rigorous on-site supervision. Most solar underperformance is not a technology problem — it is a design assumption that was never tested, or an installation detail that was never checked. We address both.
We do not simply hand over a blueprint. We engineer a system around your actual energy profile, then oversee the construction phase so the installed asset matches the one that was modelled — on time, within budget, and built for the yields we projected.
Site assessment and feasibility study
- Data collection — analysis of twelve months of utility bills to establish real consumption and peak demand
- Structural evaluation — roof structural integrity, tilt, orientation and available ground area
- Shading analysis — 3D modelling of shade from trees, adjacent buildings and obstructions across the year
Conceptual design and capacity sizing
- System sizing — optimal DC capacity (kW) based on load profile and space constraints
- Technology selection — compatible PV modules (monocrystalline or bifacial) and inverter architecture (string or microinverter)
- Storage integration — battery bank capacity where off-grid or hybrid backup is required
Detailed engineering and 3D modelling
- Layout optimisation — precise 2D and 3D electrical and physical layouts in PVsyst, AutoCAD or Helioscope
- String configuration — module strings matched to inverter voltage windows for peak performance
- Electrical design — single-line diagram covering AC/DC disconnects, combiners and main service connections
Safety and compliance engineering
- Protection systems — lightning protection, system earthing and surge protection devices
- Structural calculation — mounting structures engineered for local wind loading and seismic requirements
- Regulatory alignment — designs compliant with local utility grid codes and national electrical standards
Final documentation and bill of quantities
- Procurement list — an exhaustive BOQ covering every component, from modules down to specific cable gauges
- Yield simulation — an authorised generation report projecting monthly and annual kWh output
Construction supervision
Site inspection through mounting, stringing, inverter installation and grid connection; verification of materials against the BOQ; testing and commissioning; and handover documentation.

Common questions
Frequently asked questions
How does DMC size a solar system?
From twelve months of utility bills to establish real consumption and peak demand, combined with a structural assessment of the roof or ground area and a year-round shading analysis. The optimal DC capacity follows from the load profile and the space actually available.
What software does DMC use for solar design?
PVsyst, AutoCAD and Helioscope for layout, string configuration and yield modelling, producing an authorised generation report projecting monthly and annual kWh output.
Does DMC supervise solar installation?
Yes. Supervision runs through mounting, stringing, inverter installation and grid connection, with verification of delivered materials against the bill of quantities, testing, commissioning and handover documentation.
