Tilt your solar panels to 44° facing south in Fokino. That is the most efficient fixed angle for this exact spot, measured from satellite records of its sunshine and cloud rather than worked out from latitude. The full breakdown, including seasonal and monthly adjustments, is below.
Today, the most efficient tilt for photovoltaic panels in Fokino is 38.8°, facing south. At solar noon the sun sits 51.2° 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. Fokino 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 44°.
If you're planning to change the angle of your photovoltaic panels twice per year, the most efficient angle is 19° facing south in summer months and 56.8° facing south in winter months.
When changing the angle of your photovoltaic panels each season, the most efficient angle is 15.2° facing south in summer months and 62.2° facing south in winter months, and 39.8° facing south in autumn and spring months.
In Fokino, July is the worst month and generates 63% of what March does: about 106 kWh per kW of panels against 169. Size an array or battery for July, not for March, or it will come up short.
Averaged across the year, panels at the angle above see 5.1 peak sun hours a day. That is the figure to use when sizing an off-grid system, but size it for July rather than for the average, or it will run flat when you need it most.
If you adjust your photovoltaic panels every month, the table below gives the most efficient angle for Fokino throughout the year. The shallowest angle is 19.6° in June, and the steepest is 66.4° in December.
| Month | Optimal tilt | Sun angle at noon |
|---|---|---|
| January | 63.1° | 26.9° |
| February | 54.2° | 35.8° |
| March | 43.4° | 46.6° |
| April | 31.4° | 58.6° |
| May | 22.9° | 67.1° |
| June | 19.6° | 70.4° |
| July | 22.6° | 67.4° |
| August | 31.2° | 58.8° |
| September | 43.2° | 46.8° |
| October | 54.8° | 35.2° |
| November | 63.4° | 26.6° |
| December | 66.4° | 23.6° |
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.
For Fokino it is measured, not calculated. PVGIS, the European Commission's solar radiation model, works through years of satellite records of the sunshine and cloud at this exact coordinate and finds the fixed angle that collects the most light over a whole year. That is 44°.
Latitude sets the starting point, because it sets how high the sun climbs. It cannot see the rest: how cloudy the winters are, how much of the light arrives diffuse rather than direct, and whether hills block the low sun. A rule based on latitude alone gives 38.8° here. Across every city PVGIS has measured, that kind of rule comes out too steep more than eight times in ten. The seasonal, monthly and daily angles above do still come from latitude, because those follow the sun's height through the year, which latitude does determine. How the figures are worked out.
The angle is settled. Here is what is worth checking on the panels themselves:
