How Solar Powered Desalination Works

Solar powered desalination systems utilize solar panels to convert sunlight into electricity, which is then used to power the desalination process. The most common methods of desalination include reverse osmosis and distillation. In reverse osmosis, seawater is pumped through a membrane that removes salt and impurities, producing clean water. Distillation involves heating the seawater to create steam, which is then condensed back into liquid water, leaving the salt behind.

• Solar panels: essential for converting sunlight into electricity
• Reverse osmosis: effective method for removing salt from seawater
• Distillation: process of heating seawater to produce clean water
• Solar Technology Trends: advancements in solar energy for desalination

Example Calculation: A solar desalination plant with a capacity of 100,000 liters per day can save approximately 500 tons of CO2 emissions annually.
