Abstract: Methods for measuring solar radiation are considered and long-term data obtained by actinometric measurements of solar radiation at the location of the big solar furnace of the Academy of Sciences of Uzbekistan Institute of Materials Science Scientific Production Association "Physics-Sun", with a thermal power of 1 MW, are analyzed. Concentrators of solar radiation efficiently operate at high values of the direct flux of solar radiation, whereas photovoltaic stations operate on diffuse and total radiation, too. Therefore, the main attention is paid to the measurement of the direct flux of solar radiation. The first results until 2013 were obtained by a semi-automatic mode with the help of actinometers of the AT-50 type, after that an automated meteorological station of the MHP type with high-precision pyrheliometers CHP1, manufactured by Kipp & Zonen, was produced by the Netherlands, which is the leader in the production of solar sensors. During the operation of the Big Solar Furnace, a direct stream of solar radiation is continuously measured, since the power of the installation is directly proportional to this. The obtained long-term results of measuring the direct flux of solar radiation are processed in order to obtain average statistical data by years. To obtain reliable data on solar energy, solar sensors are annually calibrated. The last verification was carried out in January of 2018 at Kipp & Zonen.

Abstract: Bangladesh is a developing country in South-Asia. Most of the people live in the villages and that’s why around 40% of total people live under poverty line. Both renewable and non-renewable energy resources are being used here. This study is conducted to review the potentials and possibilities of renewable energy sources in Bangladesh based on the previous study and reports. Natural gas is the main source of non-renewable energy and use for electricity production. Besides coal based power plant are also producing electricity. The annual energy demand is increasing here with the world energy demand incensement. The energy crisis is higher with the higher population growth rate. Only natural gas is not enough to meet the annual demand whereas using coal and oil has bad impact on climate change. To mitigate the problem and achieve the energy goal, green energy like renewable energy is a must for Bangladesh. There is a good and effective possibility to produce energy, power and electricity from renewable energy sources like Biomass, Hydro energy, Solar energy, Biogas and Wind energy in the country. Some government and non government organizations are working with renewable energy in Bangladesh. Along with people have to be more conscious and proper man power needs to be appointed for this purpose.
