The early designs and planning for solar panels date back to the 19th century, with the first solar cell developed by Charles Fritts in 1883, marking the beginning of harnessing solar energy for practical use.

3. Obtaining Permits And Approvals

  • Review the regulations in your local area to determine which permits and approvals are necessary.
  • Submit thorough and detailed permit applications to the relevant authorities.
  • Wait for the approvals, which may require inspections or additional documentation.
  • Once approvals are received, make sure to comply with any conditions specified by the authorities.

4. Roof Preparation

  • Prepare the roof surface by clearing it of any debris, dirt, or obstructions to create a clean installation area.
  • Thoroughly inspect the roof for any damage or weak spots that may require repair before the installation process.
  • Confirm that the roof is structurally sound and capable of supporting the weight of the solar panels and mounting equipment.
  • Determine the optimal location for the solar panels to ensure maximum sun exposure and efficiency.

5. Mounting The Solar Panels

  1. Positioning: Determine the ideal location on your roof with maximum sunlight exposure.
  2. Attachment: Secure the mounting hardware to the roof, ensuring it is waterproof and sturdy.
  3. Frame Installation: Place the solar panels on the mounting structure and secure them in place.
  4. Wiring: Connect the panels to the electrical system, ensuring proper grounding and connectivity.
  5. Angle Adjustment: Set the optimal tilt angle for the panels to maximize energy production.

Fact: The angle at which solar panels are mounted can significantly impact their energy output, with the optimal angle varying based on geographical location.

6. Electrical Wiring And Connection

  • Design the electrical layout and connection of solar panels in compliance with local electrical codes.
  • Install the necessary wiring from the solar panels to the inverter, making sure to create weatherproof connections.
