Solar energy systems can make university buildings more energy efficient, but there are some big challenges to overcome:

1. High Initial Costs:

   • Setting up solar panels can be really expensive.
   • Solution: The high costs can be lowered by getting grants and forming partnerships.

2. Space Limitations:

   • Many city campuses might not have enough roof space for solar panels.
   • Solution: Use creative designs, like putting solar panels on walls instead of just roofs.

3. Intermittent Energy Supply:

   • The sun doesn’t always shine, which makes solar energy unreliable at times.
   • Solution: Pair solar panels with energy storage systems so there's a steady power supply.

4. Maintenance Issues:

   • Regular care for solar panels can be ignored because of limited budgets.
   • Solution: Create a special fund just for maintenance to help keep the system in good shape for a long time.
