MECASOLAR launches polar aligned tracker that can drive up to 114.4 kWp with one motor

The new MECASOLAR solar tracker is modular and scalable. In addition, it can be easily delivered and installed (assembled) at the location. -- It has 44 tilted axes on which an area of up to 7,855 sq ft (730 sq m) of PV panels can rotate. -- Increasing output by 30% as compared to a fixed mount system and reducing costs per Wp, it is the most competitive and profitable on the market. -- MECASOLAR will introduce the new product in these international conferences and exhibitions: SOLAR CANADA 2011 (December 5 and 6, Toronto) and INTERSOLAR India (December 14-16, Mumbai).

November 21, 2011. MECASOLAR, a multinational company specialising in the design, manufacture and sale of solar trackers, fixed structures, and foundation screws, has recently launched a new polar aligned tracker, the only PV solar tracker that can drive up to 114.4 kWp with a single controller and motor, thus reducing the costs per installed Wp. This new product allows easy transport and installation because it is fully modular and scalable, which means the final assembly can be done at the location.

This new single-axis polar aligned solar tracker (MS-1EP) by MECASOLAR carries up to 44 tilted axes on a north-south line on which the PV panels rotate. Each axis can carry a total of 2.6 kWp and all of them are interconnected via a transmission bar. One motor can drive up to 730 sq m of PV panels (max. 114.4 kWp).

Its structure is modular and scalable to 10 modules per axis, or 440 modules per tracker. The MECASOLAR polar aligned tracker is astronomically controlled. Backtracking can be used as well, which allows for increased output (+30%) and PR in the installation as compared to a fixed mount system.

MECASOLAR's new product is the result of broad experience in the PV industry and a hard-working R&D team. Competitive advantages include simple modular assembly at the solar installation, easy transport of the tracker's parts, and robust structure made of hot-dip galvanised steel (under ISO 1461 standard) that provides corrosion protection and durability.

The technicians at MECASOLAR explain that the new tracker has been designed to be used with different foundation systems (with or without concrete, via foundation screws), which saves time in assembly and ground preparation too. "Land levelling, which is not permitted by environmental authorities in certain locations, is not required, which reduces work costs and avoids affecting the land," they add.

Foundation screws can be used to fix MECASOLAR's new tracker; for example, MECASCREW, the universal foundation screw the company launched in June 2011. Compatible foundation screws are admitted in the structure as well.

Furthermore, thanks to the axes' simple modular design, they can be used with other PV modules available on the market. In addition, the system requires low maintenance and involves reduced consumption. Also, it has an active wind protection system including an anemometer and a vane to determine the safest position.

Ongoing expansion

Since its establishment in 2005 and the launch of the MS Tracker 10 and MS Tracker 10+ dual-axis trackers, MECASOLAR has been growing steadily. Proof of this are the manufacturing plants set up in Greece (2008), the USA (2009), Italy (2009), and Canada (2010). As a result, the number of solar trackers manufactured in all five plants has risen to 24,000, with 311 MW installed trackers.

The increase in manufacturing capacity and a stronger global presence have led to an enlarged product catalogue after a series of new releases:

December 2008: MS-1E TRACKER 15 and MS-1E TRACKER 15+ single-axis azimuth trackers
February 2009: MS1F/2F/3F-V Vertical and MS1F/2F/3F-H Horizontal fixed structures
June 2009: Improved MS-2E TRACKER 10 and MS-2E TRACKER 10+ 13.16 kWp dual-axis trackers, receiving the Solar Award 2009
June 2011: MECASCREW universal foundation screw for fixed installations in all types of ground
November 2011: New single-axis polar aligned modular solar tracker

The MECASOLAR products are available in all five continents, Europe being their "natural" market, followed by America, Asia, Oceania, and Africa.

Featured Product



You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
