Understanding the Data
The solar performance chart for Colombo illustrates sun hour availability throughout the year, highlighting the peak months. During these months, energy production potential is maximized, benefiting solar appliance usage.
Cost & Savings Outlook
At the country's typical rate of $0.050/kWh, solar can offset a meaningful share of electricity costs for homeowners and businesses considering solar installations.
How It Compares
Compared to Lagos and Accra, both rated 'Average', Colombo's 'Good' solar potential rating indicates a stronger opportunity for effective solar energy generation, benefiting from higher annual sun hours.
Installation Considerations
Given Colombo's latitude, solar panels should ideally be installed with a tilt angle of about 10 to 15 degrees to optimize energy collection throughout the year. Proper angle adjustment can also account for seasonal sun path changes and maximize energy potential during peak months.
Local Incentives
Check local and national incentive programs, which vary by country and region, to see how they might support solar energy development in Colombo.
Seasonal variation in sunlight is minimal in Colombo, primarily due to its tropical geography. However, it's important to consider that energy production may dip slightly during the monsoon season, which typically occurs in May and June.
In a tropical climate like Colombo's, solar panel efficiency can be influenced by higher average temperatures. While this may result in a slight decrease in output under extreme heat conditions, the abundant sunlight generally compensates by providing ample energy generation opportunities.
