Tilt your solar panels to 20° facing south in Kyaukpyu. That is the most efficient fixed angle for its latitude of 19.43°. The full breakdown, including seasonal and monthly adjustments, is below.
Today, the most efficient tilt for photovoltaic panels in Kyaukpyu is 22.8°, facing south. At solar noon the sun sits 67.2° above the horizon. Setting your panels to this angle keeps them as close to perpendicular to the sun as possible, which is where they generate the most electricity.
Your photovoltaic panels need to be angled facing south. Kyaukpyu is in the northern hemisphere, so panels catch the most sun facing south.
If you're mounting the photovoltaic panels at a stationary angle, such as on your roof, the most efficient angle is 20°.
If you're planning to change the angle of your photovoltaic panels twice per year, the most efficient angle is 2.9° facing north in summer months and 36.2° facing south in winter months.
When changing the angle of your photovoltaic panels each season, the most efficient angle is 6.4° facing north in summer months and 41.3° facing south in winter months, and 16.7° facing south in autumn and spring months.
If you adjust your photovoltaic panels every month, the table below gives the most efficient angle for Kyaukpyu throughout the year. The shallowest angle is 0.7° in May, and the steepest is 42.8° in December.
| Month | Optimal tilt | Facing | Sun angle at noon |
|---|---|---|---|
| January | 39.5° | South | 50.5° |
| February | 30.6° | South | 59.4° |
| March | 19.8° | South | 70.2° |
| April | 7.8° | South | 82.2° |
| May | 0.7° | North | 89.3° |
| June | 4.0° | North | 86.0° |
| July | 1.0° | North | 89.0° |
| August | 7.6° | South | 82.4° |
| September | 19.6° | South | 70.4° |
| October | 31.2° | South | 58.8° |
| November | 39.8° | South | 50.2° |
| December | 42.8° | South | 47.2° |
The sun angle at noon is how high the sun sits above the horizon at midday. Facing your panels south at the tilt shown for each month keeps them as close to perpendicular to the sun as possible, which is where they generate the most electricity.
It comes out of your latitude. Kyaukpyu sits at 19.43°, which puts the best fixed angle at 20°. Near the equator the midday sun is almost overhead, so panels lie close to flat, around 2°. The further from the equator you are, the lower the sun sits, and the steeper your panels have to stand to face it squarely.
The climb is not one for one. At 30° of latitude the best fixed tilt is about 28°, but at 60° of latitude it is about 46°, not 60°. The optimum flattens off toward the poles because the winter sun is low and much of the light arriving is diffuse rather than direct. Most pages on this site quote a figure PVGIS measured at the place itself; it had no answer for Kyaukpyu, so this one comes from a curve fitted to that measured data instead. See how it compares with tilt equals latitude.
The angle is settled. Here is what is worth checking on the panels themselves:
