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 tilt 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.

2.3 Mechanical Installation introduction

Solar PV modules usually can be mounted by using the following methods: screws
and clamps.
