If you are on a quest for a reliable and the best solar panels in India, one of the key metrics that you should take into account is their efficiency. To understand the productivity and to calculate the return on investment,panel efficiency is something you should measure before making a switch. Solar panel efficiency is measured by the amount of sunlight which falls on the panel and the conversion of that energy into useful electricity.Nowadays, dealers face two main issues when they purchase standard panels – Panel degradation which results in drop in power output over a period of time.Panel degradation happens because of UV exposure, weather cycles and lower quality of materials used. Panel degradation is a long-term effect and does not appear so severely in the initial 2-3 years. But later the drop-in power output starts affecting system performance and solar energy harvest.To cut through the competition, manufacturers use low-quality raw materials, Low grade solar cells, rejected lots of EVA and back sheet.

Paneles solares fotovoltaicos Hoy os traemos un maravilloso contenido sobre paneles solares. Por ejemplo, de 20 a 150 watt puede tener un valor desde 19€ por cada metro de panel solar en cambio los paneles conocidos como mono cristalinos van desde los 19€ por cada metro instalado, los mono cristalinos de 12 voltios desde 180€ aunque.
They practise it to decrease the overall cost of the panel but there are several problems and failures which come along with that. Drop-in power output happens when manufacturers degrade the quality of panel and keep the price of their products low to get more customers. In that process, productivity goes for a toss and hampers the overall energy output of the panel.
These two issues decrease the overall efficiency of the panel.That’s where Novergy panels come into the picture; they don’t degrade at the same rate as standard panels. They have higher absorption capacity and internal reflectivity. Our panels are certified and tested to most reputed International standards such as TUV, UL, IEC, CE, MNRE, Clean Energy Council, etcYou can compare with standard panels in the same size and cell configuration. The rating of Novergy solar panel efficiency is now nearing 20%, while the standard panel has only around 16% efficiency. From this, it is quite evident that Novergy panels will create 40% more electricity than the standard ones.
20% efficiency ratings of Novergy crystalline technology is 4% more than the standard panels. It clearly qualifies Novergy as the top-notch and the most efficient solar panel provider. Our panels significantly help to maximize electricity production and reduce power bills.Our solar panels are made of high-quality raw material under stringent international standards. They also have strong mechanical strength, meaning they are extremely responsive in low light conditions.
They can withstand any weather situation i.e. Snow loads and wind loads.Two factors which help you to ascertain the efficiency of a solar panel are Cell Efficiency and Total Panel Efficiency.Cell EfficiencyCell efficiency can be identified by the design of the cell and base silicon material used. It is measured by the maximum conversion of a cell at the given optimum voltage. The silicon material used can either be N-type or P-type, depending on the design and the functionality. PERC is the most advanced solar panels in the solar industry as they get the best energy harvest.
PERC cell maximizes power and performance of the overall module.is the purest form of silicon, if you use it in your panels, they will be rated most efficient. However, these silicon bases are expensive to produce. Our panels have 5 bus bar designs which enhance current transmission and increase module reliability. Novergy offers solar panels from both polycrystalline and monocrystalline series.Indirect benefits of Cell EfficiencyAnother less known fact is that cell efficiency is a very good sign of the grade of cells coming out of the factory. Usually top-grade cells have the best efficiencies and that is why it further has a lot of importance while choosing the solar panel.Total Panel EfficiencyPanel efficiency depends on a number of panel designs, size and cell layout factors. Novergy panels are designed in a way that they need less space to function and to generate electricity. They have better temperature co-efficient; Novergy panels have a reduction in energy up to 0.37% while standard panels have 0.47%.Efficiency is also determined by the type of back sheet and coating used on the solar panels.
Novergy panel has an anti-reflective coating which helps it in absorbing more light and better energy output. Our cells have lower degradation as they are made of high-grade materials.These panels are backed with a 25-years linear power output warranty and 10-years product warranty against any manufacturing defects.All things consideredNovergy, with more than 12 years of experience is one of the and the most preferred choice.

The use of photovoltaic (PV) technology in urban areas is an appropriate way to optimize the use of solar energy, since the energy conversion system is located in the same place as the demand. Thus, the losses caused by distribution networks and even technology costs are reduced; in addition, less space is required for energy production in the countryside. Energy can be produced in neighbourhood dwellings located in the periphery in low-density areas that contribute to supplying electricity to high-density urban centres. The performance of a solar system largely depends on the integration capacity of solar panels in building roofs or facades to maximize production.
This research has analysed the integration of this type of system in the roofs of new types of housing in developing countries and its adaptability attributable to the geometry of solar panels with regular-sized mono- and polycrystalline cells. This research is based on 32 sloped roof typologies built since 2010. The main results indicate that an average of 36% of the roof surfaces are not useful because of their irregularity; in addition, the small solar panels show more adaptability, although less than expected with respect to large-format PV panels.Keywords: Solar roofs; solar energy; photovoltaic; monocrystalline cells; polycrystalline cell. MethodologyIn a previous analysis by ), heating and electricity demands on buildings and some characteristics of the geometric roof were determined for different types of single-family housing typologies by identifying the location on the roof with the best solar potential in each case.
In this study, all the cases were considered by selecting the roof shape’s best characteristics and obtaining the main geometrical indicators.According to the shape and dimensions of the monocrystalline or polycrystalline silicon cell, one can obtain typical dimensions found in the market, with cells grouped in a rectangular shape that has 6 inches on each side. Although these panels are designed to be added to buildings (Building Added Photovoltaics, BAPV), it will be more interesting to construct panels to be integrated into buildings (Building Integrated Photovoltaics, BIPV). However, this research establishes the consequences of forms and panel sizes in both cases: new BIPV products and currently available BAPV products. First, an analysis of the commercial panels is developed to identify the most frequent dimensions and shapes available in the market. Second, an analysis of roof shapes in urban housing developments is performed, superimposing the solar panels on the forms of the roofs to detect tendencies, adaptability and where to receive irradiation, simulating either horizontal or vertical placement. The main output of this analysis is to determine whether the useful area of the roof for PV collection, which provides the maximum energy conversion, is strongly dependent on the panel geometry.
Characterization of photovoltaic panels geometryAccording to commercial PV product analysis, there are three types of solar panels composed of crystalline cells of 6 inches per side. In the panel classification based on the number of PV cells, the bigger panels have 72 cells, the medium-sized panels have 60 cells and the small panels have 36 cells.
There are even other solar panel sizes for solar cells and quantities, resulting in many solar-panel formats, but those analysed in this research are the most common. The 72-cell panels have 6 rows of 12 cells each, the 60-cell panels have 6 rows of 10 cells each, and the 36-cell panels have 4 rows of 9 cells each. The dimensions of the solar panels of the same number of cells, are not exactly the same, but they have very similar sizes, as shown in, with only a few millimetres of difference among them. Thus, for the analysis developed in this study, we take an average dimension of the three typologies for integration into the building roofs. This enables us to determine the capability for integrating the PV panels into roofs.The average length and width of each type of solar panel was taken as reference. Using this procedure, the reference dimensions for the solar panel of 72 cells have a length of 1,970 mm and a width of 974 mm; the 60-cell solar panel has a length of 1,643 mm and a width of 944 mm, and the 36-cell solar panel has a length of 1,497 mm and a width of 672 mm. Consequently, these dimensions are used in the roof models analysed to determine the availability of the resulting photovoltaic collecting surface.
Due to the diversity of existing formats of PV roof tiles, it is not possible to establish a similar relationship between this kind of products. In consequence, the format of the product know as 'Smooth' of Tesla inc has been adopted, considering that this typology corresponds to regular size of a roof tile. The size of this tile model is about 356 mm by 220 mm.
Analysis of the integration of solar panels into roofsBy performing a three-dimensional analysis using BIM Archicad @ 19, it was possible to configure the different solar panels’ placement or location on building roofs. Using the vector texture software tool, it is possible to superimpose the grid texture representative of the formats of 72-, 60- and 36-cell photovoltaic solar panels on the roofs. Using this as a template, the effective surfaces for collecting solar irradiation are redrawn, and the effective photovoltaic surfaces were obtained using the BIM sizing tool. The panels are located longitudinally and transversally to determine the number of panels for every panel type that can be effectively installed on the roofs.
This allows us to identify the ratio among the roof surfaces that are occupied by the solar panels while considering the overall surface available on the roofs. Although the panels used in this analysis are not designed to be architecturally integrated into the building, it is expected that in the near future, technology will be developed to integrate panels into building roofs according to IEA-SHC ( ) and developed from normal-sized silicon solar cells.
Consequently, there is a good possibility that they will be built in sizes similar to those proposed here. The solar panel of crystalline silicon cells presents a great potential for integration in buildings because of its technological maturity, its high efficiency (NREL, 2017), and its large format, which requires less installation work and poses less risk of installation mistakes. This last aspect is very closely related to the installation process, because small PV-like photovoltaic tiles require a large amount of interconnections and wiring, making it difficult to detect any connections ( b).shows the results of the best capabilities reached in each case.
From the 33 models analysed, in 18 cases the PV panels of 36 cells had the largest capacity, in 13 cases the PV panels of 60 cells had the largest capacity, and in 10 cases the PV panels of 72 cells had the largest capacity. The logical result of a better surface occupation of the smaller formats occurs; however, this situation appears only in 55% of the cases, compared to 30% of the situations, in which the largest area of effective solar capture is achieved by panels of 72 solar cells. But with smaller format of PV roof tiles, in every case, the surface occupancy is always higher. It is verified that although in most situations it is possible to use the surface area better with smaller panels, this does not mean that smaller panels will always have better adaptability, as it might seem logical; in relevant proportion, larger panels provided better occupation. In some cases, the resulting solar capture surface coincides with the deployment of different panel formats, a situation shown in the modular format of the 6-inch solar cell panels analysed in this study. Table 1 Integration of solar panels into building roofs. Source: The authors.The indicator that is considered the most important finding of this study is the proportion of occupancy of solar cells or effective PV surface against total roof area.
Curiously, among the three types of deployment, the indicator shows close results: 72-cell panels need an average of 61.5% of available roof surface, 60-cell panels need an average of 64.3% occupancy and 36-cell panels rarely obtained an occupancy lower than the 60-cell panels, reaching only 63.7%. This last indicator suggests that on average, on existing roofs, the inclusion of large format plates does not show that the solar collecting net surface is penalized. Consequently, the expected energy production will not be affected by this aspect. Regarding the best occupancy considering the longitudinal or transverse layout factor of the panels of the formats analysed, it might be believed that longitudinal deployment is the best option because of the existing longitudinal proportion in most of the roofs. However, when measuring the area of irradiation collection and its relation to the effective area in all the cases studied, longitudinal arrangement prevails in only 52% of cases, compared to the 48% that predominates in transverse deployment. In that event, factors such as orientation, inclination, and even the cost of panels and their installation process are more influential factors than longitudinal or transversal placement.On average, considering all the cases, a feasible roof occupancy by PV of 64% is obtained; however, in the best regular- and wide wing-roof reaches, 90% of PV occupancy is possible, unlike smaller and irregular wing-roof surfaces, which show occupancy of only 27% (PV surface of 4.38 m 2 against a wing-roof area of 16.22 m 2). With PV solar roof tiles, the best occupancy rate observed is 96% and the lower one reaches an 80% occupancy.
