Do you own a solar plant? Avoid these 7 mistakes with your rooftop solar

Solar energy is a popular, renewable and environmentally friendly source of electricity. But installing a solar system is complex and requires attention to detail, and some wrong practices can cause serious problems.

1. Poor site selection and component placement

Poor site selection is one of the most common mistakes. The site must receive enough sunlight to generate the desired electricity; shading reduces output and makes the system inefficient. A site that cannot support the panels risks damage or dislodging in bad weather. The solar inverter, the heart of a solar power plant, needs proper ventilation and should not be placed too close to walls or directly under the panels.

2. Selection of components

Choosing the solar inverter is the most crucial step, even though the inverter is only about 10% of the total installation cost. Weigh efficiency, durability and reliability. Wires, panels, AJBs and other components are often standardised technologies, so choose the inverter technology after research and a discussion with your installer about the pros and cons of each brand.

3. Incorrect wiring

Wiring between the panels and the inverter must be sized for the maximum current. Undersized wiring can cause a fire or short circuit, and improper connections make the system inefficient.

4. Inaccurate sizing

Panels, inverter and batteries must match the property's energy needs. An undersized system will not supply enough power; an oversized one costs more than necessary. A professional installer can help. Do not neglect future energy needs, which only increase over time.

5. Not reading the warranty card and user manual

The user manual gives safety information; skipping it may endanger you and others. Installing against the manual’s instructions may also void the warranty, leaving the product uncovered by the manufacturer.

6. Improper mounting

Mount the panels on a strong, sturdy surface so they are not damaged or dislodged in bad weather, and angle the mounting correctly to maximise the sunlight they receive.

7. Neglecting maintenance

Solar panels need regular maintenance to produce maximum power. Dust or debris reduces efficiency, so clean the panels properly, and inspect the wiring and connections regularly.

Conclusion

A solar installation needs attention to detail and should be carried out by a professional. Poor site selection, incorrect wiring, inaccurate sizing, improper mounting and neglected maintenance are common mistakes. Choosing a reputable, experienced installer helps keep your system safe, efficient and reliable.
