Polaris solar PV net news: India as direct radiation data previously (DNI) for lack of the Jawaharlal Nehru national solar plans to build the first solar-thermal power generation projects cause serious negative effects. But today, with the deployment of more than more than 100 metering station construction and India national solar energy map plan implementation, India’s solar-thermal power industry in the future will no longer have to worry about it now.
Just three years ago, India DNI data simply cannot meet the needs of solar-thermal project developers and investors, when India sun radiation on the ground data and satellite data is sorely lacking, only some of the metering station simply because of too far from the project site has the reference value.
These developments led directly to India provided new energy and renewable energy sectors of the United States national renewable energy laboratory NREL DNI data and India first phase national solar project developers great errors of the measured data.
According to industry insiders, NREL provides DNI value of the project site is 2150-2260kwh/square meters, but finally confirmed by measurement of DNI value of only 1850-1950kwh/square meters. Because he was misled by inaccurate data, project developers have suffered huge losses. In order to remedy the serious error of DNI data, developers have to invest more time and money for this project to redesign and equipment selection.
A well-informed person said: “because the actual DNI value is lower, in order to fulfil the power purchase agreement (PPA) the commitments agreed in the project requires additional 25~30% the collector field and other costs. ”
In fact, India’s climate is very variable, sometimes from dust and damp and foggy weather, suffered sandstorm foggy after monsoon weather. That dubious environmental and climatic conditions for the DNI field measurement data of the work is vital, because actual DNI data will be light and heat one of the sponsors of the project are an important basis for decision-making.
However, in the same DNI value premise, India DNI on the conversion rate and the international area of good sunlight conditions compared favourably. For example, India Rajasthan has a thermal power station, local DNI 1950kWh/m2/a, but took the plant with Spain as an average level of DNI station found that India solar thermal power plants can transport significantly more energy.
Large number of metering station will be put into operation
Now India domestic solar thermal power generation industry changes have taken place. Developers not only realized the importance of sunlight irradiation measurements, even the India Ministry of new and renewable sources of energy have also begun by C-WET (India Center for wind power technology) to take measures to overcome this India major obstacles to building solar thermal power generation projects.
So far India has deployed more than 100 more metering stations across the country, most now have been installed. The project is in India under the Ministry of new and renewable sources of energy C-WET is responsible for the implementation of the independent sector, and supported by Germany established by the Japan International cooperation agency’s strong support for solar mapping and monitoring project.
C-WET said each metering stations will be equipped with high-tech equipment and sensors for measuring solar radiation and other weather-related indicators. Some of the latest metering stations installed in India involved in energy management in schools, such as ShriMataVaishnoDevi and located in TamilNadu Prathyusha Institute of technology management at the University. C-WET metering station’s performance and maintenance problems at Prathyusha Institute of technology management organized a 2-day seminar.
The first solar energy resource Atlas
India metering station deployment project has been implemented for several years, the project with the C-WET selects 3Tier through a global tender last month to make India’s first national solar energy Atlas and reached a climax. The solar Atlas contains information photothermal and photovoltaic technologies are applicable.
India 3Tier MD NikhileshSingh told reporters: “the solar Atlas will include India national average stereo data, and includes 115 inspection records for the selected area every hour. This information would include data and direct radiation all radiation data. ”
It is understood that these records also include wind speed and temperature, and solar thermal projects must take into account a number of important data. Even more important is that these data will enable investors to analyse and forecast possible for solar thermal projects the long term operational performance.
Singh said this explanation: “India’s most drastic weather changes is the monsoon, and it comes a year of time and energy are not the same. Recorded by observing the solar Atlas of long-term data, investors can understand the past monsoon-affected areas, as well as how it affects the operation of solar thermal power plants. Then investors would have to take fully into account the investment risks and make informed investment decisions. ”
According to C-WET metering station supervisor G.Giridhar introduction, the solar Atlas will be updated on a regular basis, every month the latest detection data are to be tested after confirmation of the stand into the Atlas.
Solar thermal project future profits?
How to choose the ideal solar thermal power plant building addresses usually have to take into account a number of factors, first choose a Sun-rich regions, while also taking into account those areas most in need of energy and when most needed energy, which is a key issue to be considered.
Singh said: “in General, the variability and intensity of sunshine resources is considered a solar thermal project the most sensitive factor. These data in the solar Atlas provides a sufficient basis in this regard. Consider the power transfer, when large populations in a certain area, the region will need plenty of energy for their use. ”
In some countries, such as the United States and Morocco, they had also used a similar solar Atlas provides information to determine which areas of renewable energy is relatively abundant, and they choose to build renewable energy park in the area.
Then they will take a variety of incentives to spur renewable energy development in the region, such as the construction of new power transmission cables, building roads, expanding the park range and the construction of the necessary infrastructure.
Singh thought that these important engineering spent a lot of time and money to build, is very valuable. Planning and investment needs to take full account of these facilities which the renewable resources of the area are rich enough and when factors such as sunlight conditions the best, while also taking into account the regional climatic variability.
However, if transmission lines, population, energy demand, and other information systems analysis, geographic information systems researchers and planners can determine the direction of future energy investments, storage needs and transfer plans.
Singh believes that India can be supported by the solar Atlas for planning, formulation and implementation of those policies.
