The Dangers of DIY Solar Installation

Although DIY solar kits are available, they come with numerous challenges and risks that can turn a cost-saving attempt into an expensive mistake.

1. Electrical & Fire Hazards

  • Incorrect wiring or panel placement can lead to electrical fires.

  • Overloaded circuits may cause damage to your home’s electrical system.

  • Poor insulation and grounding can increase the risk of electrocution.

2. Insurance and Warranty Issues

  • Many home insurance policies will not cover fire damage caused by improperly installed solar systems.

  • DIY installations often void manufacturer warranties, leaving you without support if components fail.

  • Non-compliant installations may not meet municipal regulations, leading to fines or required reinstallation.

3. Inefficiency and Performance Issues

  • Improper panel placement can reduce energy generation and system efficiency.

  • Mismatched or low-quality components might not work well together, leading to power losses.

  • Lack of professional calibration can cause underperformance, increasing reliance on the grid.

4. Safety and Legal Compliance

  • Solar installations require compliance with South African National Standards (SANS).

  • DIY installations may not pass municipal inspections, preventing connection to the grid.

  • Incorrectly installed batteries pose serious explosion risks if mishandled.
