Photovoltaic solar panels are sensitive and will produce an electric current when exposed to almost any sunlight. Even on overcast days when there is very little direct sunlight the charger often picks up enough diffuse light to produce a charge. The intensity of the current produced by the battery charger can be maximized by optimizing the tilt angle of the panel in relation to the sun. In the northern hemisphere panels should face true south while in the southern hemisphere panels should face true north. The following chart indicates the angle above the horizon the panel should point for optimum efficiency.

Optimum Tilt Angles for PV Panels with Respect to Latitude

Which direction is true north?

True north points in the direction of the north star Polaris. All longitude lines are true north lines.
