SP7, a turning point in the solar tracking industry

Soltec’s single-axis tracker produces 5% higher yield compared to its competitors

Some of the main issues facing energy developers include achieving enhanced project cost-effectiveness and forming a stable relationship with reliable suppliers. Soltec, Europe’s leading solar tracker manufacturer, is well aware of this, which is why it has developed the SF7, a solar tracker that has broken barriers in terms of cost-effectiveness. In fact, anyone who has followed Soltec’s evolution will have seen how cost-effectiveness is one of the main innovation criteria of this company.

SF7 was launched this summer and follows in the wake of its big brother, the SF Utility, offering a higher yield per hectare with even lower material costs and reduced installation time given that it has fewer parts.

Looking at technical details, SF7 is the only tracker with steep-slope tolerance up to 17% on a north-south gradient. By comparison, its main competitor can only withstand up to 10% gradients. The SF7 mounting supports offer the most extensive range of assembly tolerances, perfect when constructing a solar plant on uneven terrain. And with reduced final costs, the SF7 trackers are also ideal for flat sites.

The yield of the SP7 also increases by eliminating all the array gaps, completely covering the upper part of the tracker with PV modules. As a result, the separations between the solar panels on the piles disappear, increasing yield by up to 5% more MW per hectare.

Comparisons with our nearest competitor are inevitable. We have 46% fewer piles per MW, 15% less parts and 58% less screw connections. This all adds up to faster installation. Time is also saved when supplying the units thanks to the Solhub, Soltec’s global factory stock logistics system. Site deliveries are made in packages of trackers ready for distribution in the field with low manpower requirements, plus there is no need for intermediaries between our factories and the client’s plant”, affirms Raúl Morales, CEO of Soltec.

The direct consequence of a solar tracker with fewer piles is that it saves on energy consumption during installation. It also translates into less time for pile driving, lower carbon emissions and less earthmoving works.

SF7 promises to herald a new turning point in the solar tracking industry.
