My friend who was once work as QS for a developer for many years. Due to property demand getting slow in late 2010 and he got retrenched. He had switch to another field and find it better. He feel the property development industry is getting tougher to work because over supply. Many developers actually holding the new projects because afraid of no buyer and once the project started it will incur high cost.

My own view is solar panel demand will grow. Although nowadays has many players in solar panel industry but the demand will certainly grow. EV cars will grow double digit at least for 10 years time and for people who stay landed houses they will likely install solar panel to save cost. And also more and more buildings especially factories are installing solar panel. The renewable energy is a new trend.
