Solar Pannel

  • Evaluate Roof Condition: Ensure your roof is in good condition and has enough space to install the panels. The roof should ideally face south (in the northern hemisphere) for maximum sunlight exposure.

  • Shading: Check for potential shading from trees, buildings, or other obstructions. Even small areas of shade can significantly reduce the efficiency of solar panels.

  • Roof Strength: Ensure the roof can support the weight of the solar panels and mounting hardware.​

Inverter

Common Inverter Service and Maintenance Needs:
  • Purpose: To ensure the inverter is operating correctly and efficiently.

  • How: Many inverters have built-in monitoring systems or are connected to online platforms that track performance. Check for any error messages, sudden drops in production, or irregularities in energy output​

Wiring 

DC Wiring (Direct Current Wiring)
  • Function: Carries the DC electricity generated by the solar panels to the inverter.

  • Voltage and Current: The wiring should handle the voltage and current produced by the solar array.

  • Wire Size: The wire gauge must be appropriate to minimize voltage drops and prevent overheating. For solar installations, wire sizes often range from 10 AWG to 4 AWG, depending on the current.​

Wiring (Dc And Ac Cables):

  • DC Cables: Carry the DC electricity from the solar panels to the inverter.

  • AC Cables: Carry the AC electricity from the inverter to the main service panel or breaker box.

  • ​Sizing and Conduits: Wire gauge must be appropriate for the current being carried, and cables should be installed in conduits for protection from weather and physical damage.​

DC Disconnected Switched

Main Service Panel (Breaker Panel):

  • DC Cables: Carry the DC electricity from the solar panels to the inverter.

  • AC Cables: Carry the AC electricity from the inverter to the main service panel or breaker box.

  • ​Sizing and Conduits: Wire gauge must be appropriate for the current being carried, and cables should be installed in conduits for protection from weather and physical damage.​

Net Meter (Bi-directional Meter)

  • DC Cables: Carry the DC electricity from the solar panels to the inverter.

  • AC Cables: Carry the AC electricity from the inverter to the main service panel or breaker box.

  • ​Sizing and Conduits: Wire gauge must be appropriate for the current being carried, and cables should be installed in conduits for protection from weather and physical damage.​

Safety and Protection Devices

  • Fuses and Circuit Breakers: Installed throughout the system to protect against electrical overloads or short circuits.

  • Surge Protection: Protects sensitive equipment (such as the inverter) from electrical surges caused by lightning or grid disturbances.

  • Ground Fault Protection: Detects ground faults and shuts down the inverter or panels to prevent damage or hazards.​
