The aim of this study was to perform a precise spatial distribution of solar radiation estimation using UAV as a way to use solar energy efficiently. Fixed wing UAV was used to acquire image for a precisely topographical map. The whole work can be divided into two step. In first step, images acquired by UAV are used to build a digital surface model based on point cloud method. In the next step, calculated slope and angle data is used to model clear sky solar radiation. The solar radiation data for 2015 was taken from Korean Meteorological Administration (KMA). The highest daily solar radiation appears in May of 22.7 MJ/m<sup>2</sup>, and the lowest daily solar radiation in May appears 15.7MJ/m<sup>2</sup>. And the range of daily solar radiation appears in December is 2.9 MJ/m<sup>2</sup> to 7.1 MJ/m<sup>2</sup>. These results may be useful providing input to agricultural and ecosystem that are dependent on solar radiation, such as engineers, designers, developers, and so forth, during the selection location process for solar installation.
Available solar radiation is an important source of renewable energy that determines Tunisia's productivity but has been poorly characterized. Measured solar radiation datasets are generally not available for long periods. This paper studied the method of estimates for solar radiation based on satellite imagery and on the measured data by the national institute of meteorology. Data collected from the year 2015 in three different locations in Tunisia. The objectives of this study are: a) Assess of monthly global solar radiation using data of meteorology for three stations. b) Compare measured data with two different geostationary satellites imagery in order to validate the good estimation of the satellite imagery. c) Reduce the uncertainly of the use of satellite imagery long-term solar resource by validate the estimated data with those measured by the pyranometer from the meteorological station.
In order to obtain the solar radiation data (SRD), which are crucial for the photovoltaic power station planning, for the unmeasurable areas in China, both an inverse distance weighting (IDW) method and an artificial neural network (ANN) method are adopted to generate monthly global solar radiation (MGSR) data for the studied cities in this paper. For both methods, typical MGSR data for all the cities concerned are acquired by applying the typical meteorological year (TMY) method. The results show that the IDW method is only suitable for the case where the sampled cities and the studied city have relatively concentrated distribution and similar altitudes, while the ANN method performs well not only for the forementioned case but also for the case where the cities have comparatively dispersed distribution and different altitudes.
In the present work, we studied some theoretical models to estimate the components of solar radiation received at ground level. These models take into account the effects of scattering and absorption of solar radiation during its passage through the atmosphere. They are based on the determination of transmission coefficients of different atmospheric constituents. These factors require the availability of current meteorological parameters (relative humidity, air temperature, atmospheric pressure...etc.) and geographical parameters of the considered site as latitude, longitude and altitude. In this work we propose to estimate global solar radiation in two sites of Algeria: Tamanrasset and Ilizi. For this purpose three models are used: Lacis&Hansen, Lieu & Jordan and Capderou models Models were compared on the basis of statistical error tests using the coefficient of determination (R2), the root mean square error (RMSE).
In this paper, a complementary metal-oxide-semiconductor (CMOS) calibrated monolithic illumination meter for monitoring solar radiation of tomato crops is newly proposed. The output signal is a pulse stream, it could be easily sent over a wide range of transmission media, such as package switch network, radio, optical, infrared, ultrasonic, and so on. Another innovation is that the proposed calibration method can reduce the nonlinear error arising from sun sensors. By collocating with a monolithic sun sensor, which has a radiation range of 68.9-188.7 W/m2, the corresponding output frequency ranges from 0.7 to 1.82 MHz. After calibration, a measured maximum frequency error is 1.63%. Measurement results have successfully verified all the functions and performance of the proposed calibrated monolithic illumination meter and confirmed it to be applied on monitoring solar radiation of tomato crops. The proposed CMOS calibrated monolithic illumination meter is suitable for measuring solar radiation devices, such as the devices for detecting solar radiation of crops.
The aim of this paper is to study the possibility of using wavelet transform method for solar radiation data compression. The Daubechies wavelets were utilized for analyzing the transient nature of solar radiation. The measured solar radiation was subjected to the wavelets techniques for smoothing and filtering of data that was decomposed up to level 5. The findings from this study show that the Daubechies wavelets method can be used for filtering and smoothing of solar radiation. The results presented indicate that Daubechies 10 (D10) wavelet approach is suitable for data filtering and smoothing of the solar radiation data.
Solar energy is regarded as the most vital non conventional energy sources among all fossil fuels. For the purpose of modeling of solar energy conversion device solar radiation data is most essential. Hence, accurate measurement or prediction of solar radiation data is important for a particular location. The proposed system uses a Nonlinear Autoregressive Network with Exogenous Input (NARX) model to predict solar radiation. NARX approach is used to estimate daily global solar radiation by using meteorological parameters such as sunshine duration, temperature, humidity. Solar data in Bhubaneswar, India have been used in the present case. The data for the period of 2002-2005 are used for training the NARX network while the data for the year 2006 is used for testing. The results of NARX network are evaluated on the basis of mean square error and regression coefficient.
Accurate prediction of global solar radiation (GSR) is very important for all solar energy applications such as design of solar energy system, management of solar power plants and so on. But GSR data is not easily available in all the locations of India due to cost and other technical issues in measurement techniques. Hence it is essential to predict the solar radiation by employing solar radiation prediction models with available meteorological parameters as inputs. The input parameters include sunshine duration, temperature, wind speed, atmospheric pressure, and relative humidity and so on. This work is focused on the review of Artificial Neural Network (ANN) based solar radiation prediction. The ANN based model is applicable wherever the radiation data is unavailable. From the review results, it is concluded that ANN model gives good prediction accuracy than conventional regression models with correlation coefficient ranges from 0.97 to 0.99.
Global solar radiation is essential to the earth and human beings. Because of the scarcity of solar radiation observation stations, climatologic calculation methods and interpolation techniques are commonly adopted to derive the monthly global solar radiation and generate the regional distribution map. In this paper, the Angstrom-Prescott linear regression formula is applied to calculate monthly average solar radiation. A case study of Shanghai is also designed and carried out. With the observation data of global solar radiation and sunshine-hours from one observation station, the Angstrom-Prescott linear regression formula is trained to determine all necessary parameters, by which the monthly average solar radiation data of the other six weather stations with only sunshine-hour observation data can be derived. Several distribution maps of the global solar radiation in Shanghai are then generated using interpolation models in GIS, based on which spatial and temporal variation pattern of the monthly global solar radiation is discussed.
Availability of solar radiation data is very scarce in Lebanon and it is often not accessible. The estimation of solar data is the most important parameter for designing and developing various solar energy systems such as photovoltaic, solar water heater and concentrated solar power. The main objective of this paper is to present a comparison between different estimation models for global solar radiation based on sunshine duration applicable in Lebanon. Subsequently a new correlation is proposed to estimate the monthly average daily global solar radiation in Lebanon. Measured data were obtained from photovoltaic system installed on the roof of the Industrial Research Institute during 2013-2015. Estimated data of seven previous models and a proposed coefficients model, are compared to measured data based on the root mean error, the main bias error and the maximum permissible error. The results of using the new coefficients revealed that the error is minimized, and this new correlation can be used to predict the monthly mean average daily global solar radiations.
