ΑRΜΑ SA designed and provides an innovative variable tilt solar mounting system, arma-flex, which is in essence a fixed system, capable of altering its tilt angle electromechanically, as often as needed, without requiring any labor or special equipment. It can be used with any grounding method, single or double pole, earth-screws and/or concrete blocks.
Arma-flex system enables the tilt angle variation by means of 2 threaded tubes, driven into one another, thus, altering the total support leg length. Same row legs extend and shrink in a uniform manner by means of a chain - sprocket mechanism designed to transmit and regulate the motion along each row. The operation is carried out once per row, using a mobile motor system, which can be easily attached to the one end of each. Details are shown below, while 2 short videos demonstrate the operation principal.
Users can change the tilt angle as often as they wish. Possible angles range from 20° to 45°. Other designs are achieveable and can be provided, as required per case. In a typical situation (40° latitude), 2 seasonal adjustments can add about 8 – 10% to the solar yield of the installation. The operation (e.g. for a 100 kW installation) requires about 2 hours non intense work for 1 person. No other equipment is required but a single phase power supply available at the one end of each row.

Even existing fixed tilt installations can be easily modified to use ARMA's arma-flex innovative system. For single or double pole systems, with earthscrews or concrete blocks, made of steel or aluminium, thw modification is convenient, simple and fast, requiring no more that 2-3 working days (for a 100 kW installation) with no need to interrupt operation.
Arma-flex is an ideal add-on for new solar projects and a meanigful, efficient investment for existing ones. Installation can be carried out by our distributors or the EPC team, as required per case.
