Simulations
Panel angle and direction
Which way your roof faces and how steep it is both change how much sunlight your panels catch. Turn the compass and set the tilt to see what your roof could produce over a year.

What makes a good roof for solar
- 1 South-facing is best In the Philippines the sun sits slightly to the south for most of the year, so panels facing south catch the most light.
- 2 A gentle tilt works well Because the sun is high overhead here, a low tilt suits most roofs. Around 10° or more also lets rain rinse dust off the panels.
- 3 East and west still work On a gentle roof, east- or west-facing panels lose surprisingly little. Try it above. Steep roofs facing away from the sun lose the most.
Not sure about your roof?
We'll check its direction, tilt and shade on a site visit and design the system around it.
