What are two technical challenges associated with solar panel roofs integrated with existing electrical supply in Queensland?

1. Lack of space for solar panels on existing roofs
2. Compatibility issues between solar panels and existing electrical systems
3. High upfront cost of installing solar panel roofs
4. Limited availability of skilled technicians for installation and maintenance

The correct answer is 2) Compatibility issues between solar panels and existing electrical systems Integrating solar panel roofs in Queensland faces compatibility issues with existing electrical systems and a high upfront cost.

Explanation:

Technical Challenges of Solar Panel Integration in QueenslandAmong the technical challenges associated with integrating solar panel roofs with existing electrical supply in Queensland, two are particularly significant: compatibility issues and the high upfront cost of installation. Compatibility issues arise because the electrical systems of many existing buildings may not be designed to handle the variable power output from solar panels, necessitating upgrades or added components to ensure that the system functions correctly and safely.

The high upfront cost is also a major barrier, as the initial investment in solar panels and associated storage and conversion equipment can be substantial, though it must be noted that this cost can be offset over time through savings on electricity bills.

Another factor is the intermittency of solar power, which means that solar panels generate electricity in a pattern that does not always match energy demand. This intermittency requires solar energy storage solutions such as batteries, further increasing installation costs. However, despite these challenges, the long-term benefits of reduced greenhouse gas emissions and the potential for long-term savings make solar panels a viable option for many.
