without Solar Tracking System

• By Sutrisna Limas

2
Why electricity

• Because it is difficult for human to live without
  electricity.

3
Why solar Thermal?

• Continuous and reliable energy source from the
  sun at certain area.
• No pollution.
• Low operation cost.
• Low maintenance cost.

Why varying beta

• To get maximum radiation of sunlight, at the end,
  we will get better solar system performance.
