For the 3rd consecutive year, LONGi Solar, a world leading mono-crystalline PV module manufacturer, has been named “Top Performer” in the annual PV Module Reliability Scorecard published by PV Evolution Labs (PVEL) and DNV-GL. This ranking summarizes the results of independent testing conducted as part of PVEL’s Product Qualification Program (PQP) and identifies the PV module models that achieved top performance

The PQP is a unique protocol of tests that generate empirical performance and reliability data, contributing to critical technical due diligence, energy forecasts and financial models utilized by solar investors and project developers. Manufacturers voluntarily participate in the PQP, but only “Top Performers” are eligible for listing in the Scorecard. Manufacturers choose to be recognized in the Scorecard in order to demonstrate the quality of their products to the market.

Testing for reliability and performance

According to PVEL, while IEC and UL certifications are important indicators of module safety, long-term reliability and performance are also important to PV buyers. By extending IEC 61215 sequences and incorporating additional tests, the Scorecard approximates the impact that decades of exposure in the field has on PV modules.

The Scorecard employs four demanding test sequences that stimulate PV modules long-term performance in real world conditions. It is today the most complete publicly available comparison of PV module reliability test results.

LONGi was named “Top Performer” in all four test categories:

  • Thermal cycling.
  • Damp heat.
  • Dynamic mechanical load sequence.
  • Potential induced degradation (PID).

LONGi hallmarks: technology innovations and product quality

India has an outstanding solar potential and has become one of the largest emerging PV markets. However, its solar road gets bumpy from time to time. On July 30 last year, Indian government announced a 25% safeguard duty on imported PV modules, which shocked the solar industry. As a result, India had added a solar capacity of 8,263 MW by the end of 2018, down from 9,782 MW added in 2017.

Yet, India’s rooftop solar continues its growth impressively with YoY growth rate at 66 percent. Under these circumstances, brands from China that focuses on rooftop solar are continuing their expansion across India. Growatt, the Global Top 10 Solar Inverter Supplier has been increasing its investment in India.

We’ve been here in India for over eight years. And we’ve seen through years of strong growth an enormous solar potential of Indian rooftop. One key factor is that the commercial and industrial consumers are paying higher grid tariffs and this is a good incentive for them to get PV systems on their roofs. So we are very optimistic about Indian rooftop solar market in the long term.” said Rucas Wang, Growatt Regional Director. Wang, who is very familiar with the local solar community. And he understands the potential and importance of Indian solar market.

Indian solar market is on top of our list for business growth. We started increasing our investments significantly in marketing and staffing last year. Now we have a team of 24 local sales and service engineers. Service offices have been established in eight major cities to provide on-site service across India. A toll-free service hotline has also been set up as well to provide fast response for our customers.

With continuous investments by leading solar companies like Growatt, Indian rooftop sector will probably become increasingly vigorous in coming years. And if policy and financing support comes in, rooftop installations will take off for sure.

Soltec manufactured its first tracker designed for the mounting of bifacial panels in Chile in 2015 and in 2018 opened a bifacial tracking research centre in California. Such commitment is easy to explain: a bifacial solar tracker harvests energy from both its front and rear side, capturing the sunlight reflected on the ground. And under the right conditions, yield will increase by more than 30%.

The standard features of the SF7 solar tracker from Soltec provide bifacial compatibility due to the higher mounting height, a shadow-free backside and wider service aisles between tracker rows. These features mean that the bifacial modules are further off the ground, reducing the intensity of the shading on the tracker itself while enhancing bifacial gain. It also avoids the main disadvantage of most solar trackers: the axis casting shadows on the backside of the bifacial panel.

The double-width aisles between the SF7 tracker rows help increase the capture of the albedo reflected from the ground and from the solar modules of adjacent trackers. Wider aisles also facilitate the passage of array washing and vegetation control vehicles, thereby reducing O&M costs.

The SF7 Bifacial harvests energy from both its front and rear sides, as it captures the sunlight reflected on the ground beneath the solar tracker. Given the right conditions, energy production increases by more than 30%. The solar tracker from Soltec has recently been supplied for a solar project in the Israeli region of Merhavim and Bnei Shimon. The project has a total capacity of 17 MW, of which 2 MW is produced by bifacial modules. The plant is equipped with a total of 534 units of the SF7 Single-Axis Tracker and 64 units of the SF7 Bifacial.

As Emilio Alfonso, commercial vice-president of Soltec for the EMEA region, explains: “the main challenges of this project stem from the extreme weather conditions inherent to a high altitude, desert location. Logistics created challenges when complying with the works schedule, given its location a long way from urban centres and main roads. Fortunately, our experience allows us to successfully work under this type of conditions”.

Pioneers in bifacial tracking

Soltec is a pioneer in bifacial tracking. By 2015 it had already manufactured the first tracker specifically designed to be mounted with bifacial panels for a plant located close to the La Silla European Southern Observatory in Chile. This 1.72 MWp PV plant is for experimental purposes and represents the innovation, research and development invested, making the La Silla solar tracking plant an exceptional project.

Promoted by the Italian developer Enel Green Power, with Soltec responsible for its installation and design, this plant is located on the fringes of the Atacama Desert, in the region of Coquimbo. The site stands at an altitude of 1,800 metres and covers half the energy demand of the European Southern Observatory. Its location is no coincidence for an experimental installation of this type, given that the clean atmosphere of the area facilitates the research work.

The project, which continues to be the only one of its type in the world, incorporates major PV industry innovations. Two different types of trackers have been used for three different types of modules with the aim of analysing both efficiency and productivity. For this, Soltec has specifically designed two different tracker models to maximise the production of the modules used: in the first place, conventional polycrystalline; and secondly, polycrystalline with electronic optimisation which improves efficiency under certain conditions. Lastly, bifacial technology which is the most important type of module at this solar plant.

As a result of this project, Soltec has developed the first solar tracker with bifacial modules specifically designed for industrial plants. This tracker maximises the PV yield of the bifacial module thanks to the fact it makes use of the solar energy reflected on the ground. Bifacial panels have the capacity to harvest this diffuse energy. For conventional modules and optimised modules, Soltec has designed and installed a solar tracker configured with 4 rows of 19 modules in a horizontal layout.

Moreover, the standard design of the solar trackers from Soltec offers one of the highest tolerance levels to gradients on the market: up to 17% in a N-S orientation, thereby minimising earthworks, trench laying and internal roads. The selected configurations create spacious aisles which make O&M work more efficient.

The entire implementation and development of new technologies reflect the research mission of the plant. The project developer, Enel Green Power, decided to use this plant as an experimental field in which to test different technologies under real conditions in order to improve the future of PV production.
