Competition from low natural gas prices - Low & medium temperature solar thermal Challenges - CLIMAX
In regions where natural gas based heating is popular, low natural gas prices are making it hard for solar water heaters to compete unless there are liberal incentives.
Lack of awareness of solar thermal applications
Competition from low natural gas prices
Ineffective policies and incentives
No significant cost decreases for solar thermal systems
Competition from heat pumps
Low throughput and long drying times of solar dryers
High cost of active solar dryers
Performance challenges with solar cookers
Timing challenge with solar cookers
