What Stand-Alone Solar PV Systems covers

Stand-Alone Solar PV Systems, taught in Electrical Installation Technology Level 4, covers installing and maintaining solar power that is not connected to the grid. You start with electrical basics: SI units, charge, force, work and power, Ohm's law and calculations of power, current, voltage and resistance. You then read and draw standard electrical symbols and working drawings to find the scope of the installation. Installation covers terminating the solar PV components, then the wiring: cables, joints, cable management, accessories, final circuits, wiring systems and earthing system types. Testing follows: visual inspection, continuity, insulation resistance, polarity and earth resistance tests. The last outcome is maintenance: inspection, recording findings, repairing or replacing faulty components, completing the checklist and disposing of waste.

Careers after Stand-Alone Solar PV Systems

Solar power for homes, shops and farms away from the grid depends on people who can wire, test and keep the system running.

  • Solar installation companies in Kitale - You mount and terminate solar PV components, wire final circuits and earth the system to the design. You are paid as an installer or assistant technician.
  • Off-grid maintenance contractors in Garissa - You inspect and test systems, replace faulty components, fill in maintenance checklists and dispose of waste properly. You earn on service contracts.
  • Electrical contractors in Naivasha - You add stand-alone solar work to your wiring jobs, using drawings, symbols and Ohm's law calculations to size the circuits.
  • Self-employed solar technicians in Kilifi - You install and service small systems, run the continuity, insulation, polarity and earth tests and record the findings for the customer. You earn per installation and per service visit.

Test results and maintenance records are part of the job, not an extra.
