Best alignment depends on the site (latitude) and the desired purpose.
Within Germany, deviations are small.
However, there are large differences between Norway and Italy.
Principally, the following rules apply: The farther South you are, the higher the yield
of horizontal surfaces.
In Berlin, a surface inclined by 30° and facing South will have the highest radiation
over the year, which generates about 100% of the yield possible for this latitude.
c) Freeness from Shadows
No shadow must fall on the solar module. If there is any shadow on the solar module, no power will be
generated. Even partial shadow will lead to a considerable decrease of performance.
Please observe the following.
• Keep the solar panels away from protrusions and balconies
• Avoid shadows cast by trees and buildings
☞
The most frequent sources of shadow are:
- Chimneys, vent connections
- Trees
- Skylight protrusions
d)Power Station
☞
The internal lead accumulator is charged over approx. 3 days at best sun irradiation
at first commissioning. Apart from this, charging time is 2 days at best sun irradiation
(depending on the remaining battery capacity).
• Put the “12V/24V” (9) switch into the 12V position and connect the main connection cable
permanently attached to the solar panel to the “solar panel connection for 12V/DC” (8).
• Where required, an additional lead accumulator can be connected to the “connection for
external 12V lead accumulator” for increased capacity (=longer operational time of con-
nected consumers). The additional lead accumulator must have the same v capa-
city for proper operation and charging.
• Switch on the power station using the “ON/OFF” (5) switch.
• During charging, the “charging” LED is lit (A).
• When the battery is fully charged, the “Charging” LED (12) goes out.
• When the system is working and connected properly, the status LED “Working” is lit (B).
When the battery voltage is too low to supply connected consumers, the status LED
“Working” (B) goes out.
