Which direction should a solar panel be installed in Sri Lanka?

Unlike other regions, Sri Lanka, located close to the equator, enjoys efficient solar energy generation regardless of the panel direction. While the ideal panel orientation is typically south-facing, it’s important to consider the roof’s inclination, which can impact energy generation.

How do I determine the potential capacity of my solar system?

Measuring the available roof space is a crucial step in determining the potential capacity of your PV system. Begin by measuring the unshaded area on your roof where solar panels can be installed effectively. Unlike other regions, Sri Lanka, located close to the equator, enjoys efficient solar energy generation regardless of the panel direction.

How many panels are needed for a home solar system?

Size of a Single Panel Approx: 28 sq.ft Installable Panel Quantity: 10 Panels Required Roof Space: 28 * 10 = 280 sq.ft —————————————- Selecting the right installation capacity for your home PV system is a crucial step toward maximising your solar energy benefits.

Can a roof withstand the load of a solar PV system?

Check if the roof is able to withstand the loading of the solar PV system before commencement of the installation works. The design of a solar PV system mounting structure should allow for thermal expansion and contraction (e.g., thermal breaks and gaps). This is particularly important for large mounting structures.

What is the optimal angle of inclination for a flat plate solar PV module?

The optimal angle of inclination of a flat plate solar PV module is approximately the latitude of the location of installation facing south. Minimum tilt of 10° is recommended to take advantage of self-cleaning during rain events. The mounting structure shall be anchored to the roof structure.

Where should a solar array be tested?

For arrays that have no accessible conductive parts (e.g. PV roof tiles) the test shall be between array cables and the building earth. Where test method 2 is adopted, to minimise the risk from electrical arcs, the array positive and negative cables should be short-circuited in a safe manner.
