A+ Sun Systems solar tensile structures among the 20 most promising technologies in PV market

Array Changing Technologies

As another year of solar innovations marches on, with exciting new products and models being introduced up and down the supply chain, pv magazine has brought together a jury of industry experts to honor those technologies whose potential is truly Array Changing. Here, we’ve added another 10 innovations to those featured back in June, and tasked our expert jury with deciding on five standout entries from the list.

These select finalists will also qualify as candidates for the inaugural pv magazine Award, which will be given at the end of the year and cover all of the industry’s major segments. First though, a preview of 10 new products added to the list since June.

A+ Sun Systems SunNet Ground mounting system A+ Sun Systems is introducing its SunNet Ground, a steel cable mounting system for ground-mounted photovoltaic plants. It consists of steel wire ropes anchored at the extremities, offering an easy way to increase the tension, and a special hook, which the company states is a breeze to install. Because the modules are suspended on cables, they can cover extremely irregular surfaces such as curved landfills, steep hilly quarries, or agricultural land in which it is undesirable to forfeit land area to mounting structures. The modules can even be suspended over water. In standard ground applications, according to A+ Sun Systems, tensile cable racking offers the opportunity to have much larger spans between posts, reducing installation cost, and resulting in up to 65% weight reduction. Having thin wire rope and few easels under the panels, the racking system optimizes performance of bifacial PV panels. A+ also notes that SunNet Ground can be used with trackers.

A+SunSystems al 7° posto della classifica di PV magazine per sistemi di montaggio innovativi

In booming PV markets it has been observed that the more straightforward locations are invariably the first to be developed. Rep- resenting the low hanging fruit, it leaves behind more difficult sloping land for ground- mounted arrays or more straightforward flat- roof and curved roof commercial applications. Italy’s A+ Sun Systems believes its tensile- steel-wire-rope solution can be applied to such difficult locations in a cost-effective way. The SunNet Ground employs the tensile-rope solution in a way that the company claims reduces the need for expensive soil and site analysis and does not require the use of GPS or laser point equipment.


“Tensile structureis a very smart system,” says Shin Morimoto, the CEO Copia Energy, which has applied A+ Sun Systems’ tensile approach to mounting structures.

The company, based in San Bonifacio in Italy’s north, has supplied three pilot projects in Japan. Working with local EPCs, A+ Sun Sys- tems has supplied one flat roof project with its SunNetRoof system, and two ground-mounted projects on sloping ground.

A+ Sun Systems claims that the use of ram- ming equipment is not required through the application of the SunNet Ground, as the anchor points employ micro piles requiring only light pneumatics drills for the installation. The anchor points employ screw pillars that can be at the end of a 150 to 200 meter row. Beyond that, hammers and pneumatic drills are all that is required for the installation of the PV system.

“A+ Sun Systems’ solar tensile structure is made in flexible steel cable and micro piles,” says Alberto Di Gaetano, a spokesperson
for the company. “This makes it suitable for hilly lands and sloping ground. What’s more, unskilled operators are sufficient to use a jackhammer and install a tensile structure. This overcomes the big lack of skilled labor in Japan.”

The range of A+ Sun System mounting sys- tems, suitable for the burgeoning rooftop mar- ket along with ground-mounted applications, come pre-assembled and at 2 kg/m2 (0.41 lbs/ ft2) are lightweight when compared to more common steel or even aluminum structures.

A+ Sun Systems’ tensile-steel-wire-rope solution SunNet Ground can be applied to difficult locations without using ramming equipment.

A+ Systems says its engineers are available to consult to and support EPCs and installation firms. The range of A+ Sun System solutions are patent pending.

Tensile roof structure

Tensile roof structure

Tensile roof structure Italy-based tensile structure specialists for the solar PV industry A+ Sun Systems last month realized the completion of a new PV plant in Italy with the use of the company’s new SunNet Roof tensile structure. The SunNet Roof installation took just two days to complete and consists of a tensile structure of steel cables that required no ballast and no roof drilling. The installation is located in Milan and comprises a roof divided into two parts. The first part of the roof – home to a 14.4 kW array – was 13 meters long and was fitted with a tensile structure weighing 1.37 kg/m2. The second array, on a separate roof, was a 10.3 kW installation across 23 meters and fitted with a tensile structure of 0.75 kg/m2. A+ Sun Systems’ installers anchored the SunNet Roof tensile structure to the balustrades of the roof with the use of small plugs. No drilling of the roof membrane was required – the installers simply clipped the trestles on to the roof to protect against possible water leakages. The result was an ultra quick installation that is ultra light and suitable for rooftops with limited static load. The structure also enables the panels to pivot, allowing for easy access for maintenance.

Research to slash BOS costs

Research to slash BOS costs

BOS hardware: Fostered in large part by the U.S. Department of Energy’s SunShot program, several new projects are expected to begin commercialization by year’s end with promises of up to 75% combined balance of system cost reduction.

One European manufacturer of mounting systems that is bringing fresh design to the U.S. market is A+ Sun Systems, based in San Bonifacio, Italy. The company’s first high tension wire rope racking system in California will be installed on an unusually shaped roof with limited options for anchor points to support a PV array. “The reason many of our installations win out over conventional racking is not a question of cost but rather mere feasibility,” says Alberto Di Gaetano, the Managing Director of the company. “Considering the savings of our system – no ballast, zero or almost zero membrane drilling, super-fast installation, and one third the weight of traditional mounting systems – an installer can save up to 40% of their total costs,” he says. The A+ design permits arrays over arched roofs, down steep grades of terrain, over obstacles, and they can be attached vertically on structures like silos. For commercial flat roofs with limited static load reserve to support solar panels, the wire rope system has the advantage of imparting little over 10 kilograms of weight per square meter compared to 15 kg/m2 for systems requiring drilling, or compared to over 30 kg/m2 for aerodynamic systems on a 10 degree slope, or to about 65 kg/m2 for systems on a 30 degree slope requiring ballast, the company indicates. Overall, the A+ support system represents only one third of the total PV system weight – with panels representing the other two thirds of the weight. In contrast, the traditional PV racking systems requiring ballast for the sloped roofs can be six times as much weight as the panels, Di Gaetano indicates.

Correction

pv magazine, April 2014 issue, article titled, Research to slash BOS costs, p. 68: Last issue, pv magazine erroneously stated that the A+ mounting system from A+ Sun Systems represented one third of the total PV system weight. We apologize for this error. In fact, the A+ tensile structure represents only one third of traditional mounting system weight, says Alberto Di Gaetano, the company MD, and does not use ballast. These two factors combined allow installation on weak roofs with the advantage of zero (or very little) roof membrane drilling. This is possible on flat, sloped and round roofs.

A growing but volatile market

The German PV market has become less important for the manufacturers of open-land mounting systems. In other parts of the world, however, more large solar farms are being built. The equipment producers are reacting to the changing situation with new systems and savings in materials and assembly costs.

The Italian manufacturer A+ Sun Systems is taking a completely different route. Since the middle of 2012, the startup company has been offering a mounting system in which the modules are placed on steel wire. Systems with a capacity of 500 kW have so far been installed in Italy, reports Alessia Moratti of the Marketing Department. The company is working with the German systems supplier Conergy and is currently expanding its sales operations in Africa, Europe and the Far East.
