Solar Power System Design

I'm in need of a comprehensive solar power system design. I will provide a roof sketch with measurements and orientation as well as my estimated daily power requirement, which exceeds 20 kWh.

Key project components:
- Evaluate and propose the optimal solar power solution based on my location
- Determine the number of solar panels required
- Specify the appropriate inverter size
- Design a battery backup system for 24 hours of operation
- Create a detailed Bill of Quantities (BOQ)

I am primarily installing this system to reduce electricity bills, so cost efficiency is key. I have a preference for Monocrystalline solar panels, so experience with these is beneficial.

Ideal skills and experience:
- Solar power system design and engineering
- Knowledge of Monocrystalline solar panels
- Cost analysis and efficiency optimization
- Ability to create a detailed BOQ
- Experience with roof-based solar installations.
