Setting up photovoltaic (PV) systems requires careful planning, design precision, and systematic execution. In professional engineering and installation workflows, “Solarius-PV” is not a physical brand of physical hardware panels, but rather Solarius PV by ACCA software—a leading BIM-integrated solar design program used to calculate, model, and size grid-connected systems.
Whether you are using specialized design layouts to map your system or implementing a physical setup, here is the complete step-by-step breakdown of how a solar PV installation project is executed from concept to power-on. Phase 1: Planning and Software Design
Before touching a wrench, the entire installation must be simulated to verify structural compatibility and energy yields.
Site Assessment: Document local weather patterns, roof pitch, and structural integrity.
Shading & Radiation Analysis: Input geographic coordinates into software like Solarius PV to trace horizon shading and optimize panel tilt angles.
Component Sizing: Calculate electrical loads to match your solar array capacity with appropriate battery bank sizes and inverters.
Permitting: Secure essential municipal construction permits and utility interconnection approvals. Phase 2: Structural Roof Setup
Once design layouts and single-line diagrams are generated, the physical installation begins on-site with structural framing.
Anchor Placement: Locate roof rafters and securely screw structural mounting brackets or flashing feet into the main beams.
Waterproofing: Apply heavy-duty exterior roofing caulk around all penetrations to guarantee leak prevention.
Rail Alignment: Bolt metal aluminum racking rails horizontally across the mounting brackets.
Leveling: Verify precise leveling and coplanarity across the structural rails to prevent mechanical stress on the modules. Phase 3: Electrical Infrastructure
All high-voltage conversion and management equipment must be positioned and safely wired prior to securing the panels.
Inverter Mounting: Fix your central string inverter or battery-coupled system to a cool, shaded exterior wall or garage space.
Microinverter Installation: If using microinverters instead of a central unit, bolt individual microinverters directly to the racking rails underneath each panel location.
Junction Box Setup: Install outdoor-rated pass-through boxes on the roof to transition raw panel wiring into protective conduits.
Conduit Routing: Run heavy-duty PVC or metal conduit from the rooftop junction point down to the main electrical panel infrastructure. Phase 4: Panel Mounting and Wiring
This step involves handling the physical PV modules and making the live electrical connections.
