The extensive R&D and Reliability Testing labs set up at both our plants i.e. Bengaluru and Hyderabad ensure that RenewSys keeps pace with the global developments in Solar PV Technology.
Our teams are continually working on improving the life, ruggedness and performance of our products.
Here are some research papers presented by the team:
LOSS ANALYSIS ON INLINE PROCESSED MULTI CRYSTALLINE SILICON SOLAR CELLS
ABSTRACT: Crystalline silicon solar cells are well positioned in the photovoltaic (PV) industry due to their electrical performance and reliability over other solar cells. Different types of process approaches (inline/batch) play significant roles in the PV cell performance and its reliability. In order to validate the cell performance with respect to the type of process, it is important to do a systematic analysis on partially processed cells and in completed cells as well.
THE EFFECT OF DEGREE OF GEL CONTENT OF EVA ENCAPSULANT ON THE PROPERTIES OF ENCAPSULANT ITSELF AND FINALLY ON THE RELIABILITY OF THE SOLAR MODULE IN THE FIELD
ABSTRACT: The present study involve the effect of the gel content of the EVA on its performance parameters like Tensile Strength, Elongation, Transparency, Yellowness Index, Volume Resistivity, Adhesion strength, Environmental stability & UV stability; and finally; the net impact of these properties on the performance and durability aspects of PV modules.
INFLUENCE OF MVTR OF AIR-SIDE LAYER OF BACKSHEET ON THE RELIABILITY OF BACKSHEET ITSELF AND CONSEQUENTLY ON THE RELIABILITY OF SOLAR PV MODULE
ABSTRACT: Moisture Vapour Transmission Rate (MVTR), also called Water Vapour Transmission Rate (WVTR) of air-side layer of PV Backsheets plays a significant role on the performance and durability of Backsheet and consequently on the reliability of the PV module. This study reveals that the performance and the reliability of photovoltaic modules are highly influenced by the MVTR of the air-side layer of Backsheet if the core layer of the Backsheet is Polyester based.
EFFECT OF DIFFERENT UV CUT OFF WAVELENGTHS IN EVA ENCAPSULANT ON CR-SI PVMODULE’S PERFORMANCE & RELIABILITY
ABSTRACT: High energy UV radiations are harmful for polymeric materials such as Encapsulant & Backsheet used in the manufacture of PV modules. To protect the PV modules against UV degradation, EVA Encapsulant is added with additive, which cuts off the harmful wavelength present in the sunlight. The PV industry is gradually moving towards Lower UV cut-off wavelengths for the front side of EVA Encapsulant in order to harness the UV radiation up to 300nm, as against 360 nm conventionally.
EFFECTS OF TEXTURE ADDICTIVE IN LARGE-AREA DIAMOND WIRE CUT MULTI CRYSTALLINE SILICON SOLAR CELLS
ABSTRACT: The silicon PV industry has predominantly used silicon wafers sliced by a steel wire, with silicon carbide particles (slurry wire - SW) as an abrasive and polyethylene glycol as a coolant. Low yield, high total thickness variation (TTV), significant material waste and short wire lifetime (and thus high downtime) of SW cutting technology have prompted the wafer slicing industry to develop an alternative technology.
