As a result, the industry is realizing that in order to achieve
combiner boxes etc.
is required, rather than continued emphasis on individual
to decrease the system cost of other components like BOS,
the next level of cost reduction, a system level approach components.
The Goldi 1500 Volt system module will eventually lower the cost of large scale utility projects.
WHY IS THERE A NEED FOR 1500V MODULES? Module prices have come down faster than inverter and
electrical balance of systems (BOS) costs. Over the last four years, module costs have fallen by about 73%, inverter costs have declined by 56% and electrical BOS costs
have fallen by 9%. Since module prices have decreased so dramatically, the focus is on inverter and BOS costs
because they now make up a larger percentage of total system costs.
Unfortunately, it is increasingly difficult to reduce inverter and electrical BOS costs. Many inverter suppliers have already reached economies of scale and applied cost
reduction techniques to lower their prices. It’s difficult to
go beyond these accomplishments without a significant degree of innovation.
WHAT ARE THE BENEFITS OF 1500V MODULES?
power generation increases when DC-side voltage rises from 1000V to 1500V.
Larger array blocks eventually save on the components and on the labour.
Due to our in-house stringent quality tests, Goldi 1500V
modules will stand the test of time, eventually proving 1500V modules lead to longer string length and thereby
their efficiency, high performance and ruggedness.
use fewer components as compared to conventional power plants.
Raising the system voltage to 1500 volts allows for 50
percent longer strings which eliminate 33 percent of the combiners and wiring in a system. The panel will reduce the amount of total PV electrical materials by 14%, leading to a 10% decrease in the BOS cost.
Less volumes of equipment such as inverters or
transformers due to higher power density is also beneficial to reducing the costs of transportation and maintenance along with giving inventory flexibility.
Due to less equipment, costs of post-operation and maintenance will be reduced accordingly.
Besides, electrical BOS components have their own distinct challenges to drive costs down. For example, combiner
and other cabling costs closely follow commodity pricing, which makes it difficult to reduce costs without impacting the already razor-thin margins.
Assuming the length and diameter of the cables are
confirmed and the resistance R is constant, the cable loss will be 1/2.25 when the current lowers 1.5 times, as Ohm’s
Law P=I2R. To sum up, equipment loss will reduce and

Company Feature GOODWE FACILITATES RENEWABLE CONSTRUCTIONS IN C&I MARKETS Thanks to the technology development in these years, solar energy is well accepted and applied globally with cost reduction of whole system, especially falling price of PV modules. As one of the major PV markets, Indian market installed close to 9.5 GW solar projects in last year. Along with the idea of energy-saving and emission-reduction becoming popular in India, 2 GW solar capacity is expected in this year in its commercial and industrial markets. TATA Power, Sterling & Wilson together with other EPC giants are making tremendous contributions in building a greener future for India as they are paying more attentions to C&I projects. With a total capacity of 6.063 MWp, Mangalore Refinery and Petrochemicals Limited was reported successfully having a commissioned largest solar power project in a refinery site. The solar power project is spread across 34 rooftops within the refinery premises comprising both RCC and sloping sheet steel roofs. “These solar plants generate more than 24,000 units per day amounting to more than 8.8 million units per annum.” Furthermore, Cochin International Airport Limited, which has always been adhered to the philosophy of sustainable development, is completing its latest phase of 10MW solar project that guarantees 100% renewable energy supply. GoodWe string inverters are widely used in these C&I projects. GoodWe MT Series inverters (50-70kW) are most suitable for Indian C&I solar market, which can be successfully deployed on large scale commercial rooftops and ground-mounted solar PV plants and can help further reduce installation costs while its power boost function provides higher yield and a faster ROI. GoodWe is happy to see the rapid development of India’s PV industry. However, when many PV manufacturers have been flooding in India, a vicious price war between manufacturers has cut margins to the bone which will disrupt the healthy development of PV industry as well as provide opportunities for low-cost inferior products. Mr. Huang Min, CEO of GoodWe said, “Faced with vicious price war, we can never follow the trend at the expense of long-term development for both the company and the industry. GoodWe’s philosophy is to always create winwin partnerships by identifying and integrating the most advanced components and techniques available”. GoodWe’s revenue in 2017 is $200 million with an average monthly sales volume of 30,000 pieces, which increased 100% compared with 2016. According to the report about global inverter shipments from IHS Markit, the leading source of information, insight and analytics in critical areas, GoodWe ranked 8th in the 2017 World PV inverter market and secures top 10 World PV Inverter Market in 2018 Q1.

Case Study SOILING LOSSES OPTIMIZATION IN FIELD: A CASE STUDY IN GUJARAT
Soiling of PV modules in a solar power plant causes huge loss of generation to the project developer. In India, soiling is a bit of concern in plants that are located in dusty areas

like Rajasthan, Gujarat, Telangana, etc. More so regions like Rajasthan and Northern Gujarat are affected by frequent dust storms during summer season. A standard practice being followed in industry is to clean modules twice in a month (except rainy season). But this may not be providing the developer with the optimum cleaning cycles and he may be under-cleaning or over-cleaning the modules. Plants located near dust producing industrial units like cement factories, cotton mills, etc. wil also provide lower energy generation due to heavy dust accumulation on modules. For such plants, more than normal frequency of module cleaning is required. The soiling conditions do differ from season to season. In summer, a large impact on soiling can be seen on the plant generation due to large amount of dust in air. Whereas in rainy season or months after rainy season the dust would have settled down and soiling losses may be reduced significantly. Thus while conducting soiling study for this plant, the year was divided into the following 5 seasons: 1. Summer – March and April 2. Dusty Summer – May and June 3. Rainy – July, August and September 4. Autumn – October and November 5. Winter – December, January and February The module’s spectral response will also be factor in

In rainy season, the module cleaning is rather subjective. The rains if they are falling fairly frequently like one drizzle a day, the modules are getting cleaned daily resulting in almost zero soiling losses and no cleaning will be needed for that period. The start of module cleaning in rainy season should be decided by the site operator by taking inputs from weather forecasts. The objective of the cleaning to be carried out in the rainy season should be to restrict soiling losses below the prescribed value obtained through optimization. Further studies will be required to determine the exact start (g) Module Soiling on Eighteenth Test Day the Last Test Day

Two adjacent module mounting structures (MMS) were selected from the field in such a way that they were placed one behind another and their strings were connected to the same inverter. One of these two structures was cleaned every 3 days and the other was left uncleaned for the entirety of the test period. Measurements of string currents and voltages were taken once in a day preferably in the afternoon to ensure that measurements were taken under high irradiation conditions. High irradiations cannot be always guaranteed in the afternoon and in some cases, the entire day may be cloudy or foggy. On such days, the measurements could be taken at other times which have decent irradiation or values of adjacent day in the same cleaning cycle can be chosen.

CONCLUSION: In views of the results obtained from the case study, it is suitable for the module cleaning cycle to be carried out at an interval of 14 days which essentially translates to 2 times in a month. This would provide an average soiling loss of around 1.60% for the plant. Since the tandem silicon modules used in this plant are heavily dependent on visible wavelengths for power production, the variation in length of cleaning cycle over the seasons is relatively small.

The project chosen for this study is 20 MWp Solar project located in Gujarat Solar Park. This plant has been constructed using Sharp Tandem Silicon Thin film modules and is in operation for the last 6 years. By nature, a tandem silicon solar cell is more dependent on the visual spectrum of the solar spectra and thus gets more affected by the soiling. The soiling losses studies for this plant were carried out for all of the 5 seasons mentioned above. In the summer months, the optimized cleaning cycle has length of 14 days and results in a soiling loss of 1.64%. In the dusty summer months of May and June, the optimized

Electric vehicles will finally start realizing their potential, paving the way for new synergies with stationary energy storage
In 2018, the technology for floating PV systems will move from niche applications to steady market uptake, say market researchers Edurne Zoco and Sam Wilkinson at IHS Markit Solar and Energy Storage. These save land use, reduce evaporation from reservoirs and generate more electricity by using the cooling effect of water. To date China, Japan, and South Korea have deployed the bulk of the more than 450 MW of installed floating photovoltaic (PV) panels.
the resurgence of multicrystalline is the implementation of diamond wire sawing. IHS Markit forecasts that the use of diamond wire saws for cutting multicrystalline wafers will reach significant penetration rates in 2018, with major players enter mass production.
Using diamond wire saws will increase wafer efficiency as well as reduce kerf and production costs, helping make multicrystalline costs competitive again in the next couple of years by reducing the cost of each multicrystalline wafer piece by up to 15%.
the researchers. This allows suppliers to work with new partners in parallel industries, such as e-mobility, energy storage, lighting, heating, and cooling. In the last few years, industrial PV inverter suppliers such as ABB, Schneider Electric, and GE have developed digital platforms, particularly for microgrid applications. These companies are rapidly expanding their capabilities to work with new customers and applications. Other companies are rapidly expanding their hardware portfolios and software/cloud capabilities so that they, too, can develop a digital services platform. These include PV inverter suppliers with a large market share in residential, such as Enphase, SolarEdge, and Panasonic; as well as suppliers that boast of a large installed base, such as SMA and Huawei.
The combination of solar together with batteries has long been recognized as a solution to this problem, smoothing the variations in a solar plant’s output and storing electricity during the day, allowing the system to provide power into the evening. In the past, the high cost of batteries prohibited these types of systems. However, the huge drop in the price of lithium-ion batteries—nearly 70% between 2012 and 2017— has now made utility-scale solar plus storage cost-effective and a reality in some places. Parts of the United States, as well as Australia, that are planning large planned utility-scale PV plants are now adding storage to provide firm power supply, resulting in the building of a

with the addition of a software and cloud platform say
China will consolidate its position as the world leader in 2018, having already completed the world’s largest floating PV system of 40 MW, alongside plans to continue with 70 MW and 150 MW projects in Q1. While China is set to stay at the forefront, new potential markets are also emerging, such as India with a 10 GW tender, and the Netherlands with a 2.3 GW plan by 2023. This rapid growth of market opportunities will increase the number of companies with floating solar initiatives and give the current market leader, French-based Ciel et Terre, more competition.
Some of the key module technology improvements that players are prioritizing now are bifacial and half-cell. Bifacial promises all the advantages of glass-glass, such as lower LID, higher resistance, and higher tolerance for harsh environments. Moreover, bifacial can potentially generate 10-15% more electricity from the rear side, accompanied by only a limited increase in costs. For its part, half-cell technology aims to reduce cell-to-module losses by optimizing ribbon thickness. This new module design allows more cells to be placed into a module of a given size and increasing power output by 5-10 watts, potentially at a lower cost per watt. For both technologies, the increased output from one single module will also contribute to system cost reductions (on a per-watt basis). This applies to balance-of-system components (BoS), land, and transportation, among other factors, compared to a
