GreenDrive – Solar Power for Golf Carts

The entire solar system for autarkic power supply of the golf cart consists of the solar module HES-104-350 with frame including the complete charge electronics for 48V lead acid batteries with temperature compensation and LCD display. The display shows the generated energy, the avoided amount of CO2 and other data. It can also show the current values or the total yields.

The solar cells used have a contact-free, dark blue surface and a very high energy conversion of 22%. The base plate with fibreglass reinforcement has an aluminium coloured surface on both sides and is covered with a UV and weather resistant foil on the top. Due to its special construction, the module is semi-flexible, robust and lightweight. The module is fixed on a frame made of brushed stainless steel, which can be attached to various golf cart models.

Power Indicator

The power indicator is mounted underneath of the solar panel. It is rotatable which allows adjustment to the viewing angle.

The device performs regularly precise measurements of the relevant parameters such as charge current, power, temperature, time, etc. The recorded data is processed and stored internally and can be displayed by pressing a button on the LCD display.
