• It uses a commercially available solar panel made from high efficiency cells. 
• A solarimeter on the frame measures incident radiation.
• The equipment also includes a second lower rated battery. 
• A control module contains the charge controller.
• The panel recharges a choice of two batteries through a charge controller. 
• The frame holds a high performance deep cycling battery in a storage box. 
• The control module has digital displays and shows the panel and battery storage performance. 
• It has indicators to show when the charge controller is in float mode and load cut mode. 
• The charge controller recharges the battery at the correct rate of charge without damage to the battery. 
• The solar panel is on a wheeled, lightweight frame that allows adjustment of panel angle, relative to the sun.
• This allows students to examine the charge and discharge cycle of the system in a typical laboratory session. 

A separate loading unit includes:

• A variable resistive load to show battery performance.
• An inverter to show practical conversion to AC voltages.
• Four switchable lamps to show a practical application.
