Solar energy works by capturing sunlight using photovoltaic (PV) panels, which convert sunlight directly into electricity. These solar panels are typically installed on rooftops or open land. The electricity generated can power homes, businesses, or be stored in batteries for later use. If connected to the grid, (Lucelec), excess electricity can be sent back to the utility company, often earning credits through a system called Net Metering. 

Yes, solar energy is becoming increasingly cost-effective. Although the initial installation cost can be high, many people recover this cost within 5 to 10 years through savings on their electricity bills. Currently in St. Lucia there is a credit system through Lucelec called Net Metering. which provides a credit on your utility bill, if your Grid Tied Solar System, produces excess energy and is sent back to Lucelec’s Grid. Over a system’s 25+ year lifespan, solar can provide significant financial savings. 

Solar panels produce less electricity on cloudy days and none at night. However, most systems are either:

Connected to the grid ( Lucelec), allowing you to draw electricity when solar isn’t producing, or equipped with battery storage, which stores extra energy produced during the day for use at night. In either case, modern solar setups are designed to ensure reliable power regardless of weather or time.
