When solar modules are used to charge batteries, the battery must be installed in a manner,
which will protect the performance of the system and the safety of its users. Follow the
battery manufacturer‟s guidelines concerning installation, operation and maintenance
recommendations. In general, the battery (or battery bank) should be away from the main
flow of people and animal traffic. Select a battery site that is protected from sunlight, rain,
snow, debris, and is well ventilated. Most batteries generate hydrogen gas when charging,
which can be explosive. Do not light matches or create sparks near the battery bank. When a
battery is installed outdoors, it should be placed in an insulated and ventilated battery case
specifically designed for the purpose.
Do not install the PV module in a location where it would be immersed in water or continually
exposed to water from a sprinkler or fountain etc.
2.2.3 Tilt angle selection
The tilt angle of the PV module is measured between the surface of the PV module and a
horizontal ground surface (Figure 1). The PV module generates maximum output power
when it faces the sun directly.
Figure1: PV module title angle
For standalone systems with batteries where the PV modules are attached to a permanent
structure, the tilt angle of the PV modules should be selected to optimize the performance
based on seasonal load and sunlight. In general, if the PV output is adequate when
irradiance is low (e.g., winter), then the angle chosen should be adequate during the rest of
the year. For grid-connected installations where the PV modules are attached to a permanent
structure, PV modules should be tilted so that the energy production from the PV modules will
be maximized on an annual basis.
