The basic condition of operating a solar equipment is to have the Sun shining on it. In case of a solar collector the round shape of the tubes will allow to receive sun from many angle, that is why your collector will work even in grey weather. Basically, the more sun a solar equipment gets the better.
It’s important to place the solar equipment so it gets most sun possible, during the full path of the sun. And where there are no obstacles, like trees, houses or other things shadowing the absorber area, perhaps in the morning or in the afternoon.
Place yourself exactly where the solar equipment should be and bring a compass to get oriented exactly towards South. This is where you want your equipment to point. It’s important your head is in the same level as the absorber area (vacuum tube and/or solar panel). Hereafter turn your head and use below map to see if there are obstacles in the full path of the sun. The fewer obstacles, the more efficient your equipment will be working.
We recommend the angle of your absorber area to be close to 45 degrees. This will optimize the weaker ends of the season.
Hungary’s latitude is 47° 00′ N, above path is based on 45° 00′.
Each vertical line represents the time of the day. Placing your mousecursor within the graphic will show the month and the exact altitude and azimuth angle.
On the left axis the solar altitude angle while on the right axis the optimal angle of your solar equipment is indicated.
