Instantaneous measurements of solar energy can help you position your solar panel for maximum efficiency.
Solar radiation is given in units of kWh per unit area per unit time • Daily solar radiation will be kWh/m2/day • Monthly solar radiation will be kWh/m2/month • Yearly Solar radiation will be kWh/m2/year Typically in India solar radiation varies between 4 -7 kWh/m2/day or about 1400 -2500 kWh/m2/year. How we present Solar Radiation?
Knowing the metrics for solar radiation can help with your analysis. The intensity of the sun varies by the clarity of the atmosphere and the angle at which the sun strikes a surface, called the "incident angle." The more perpendicular the sun''s
Thus if we assume we need 1000 watts per day of solar energy to power our home, we could do this during the summer months with just one 200 watt photovoltaic panel, but would require four 200W panels during the winter
Irradiance is the power of solar radiation per unit area the international system of units, it is measured in (W/m 2).. Solar irradiation is the quantity that measures the energy per unit area of incident solar radiation on a surface - the power received during a time (J/m 2 or Wh/m 2).. The term solar radiation is a generic concept, but it is not quantified to any magnitude.
Thus if we assume we need 1000 watts per day of solar energy to power our home, we could do this during the summer months with just one 200 watt photovoltaic panel, but would require four 200W panels during the winter months. Solar irradiance is a measure of the suns intensity or power density over a certain area, commonly defined as being

An alternative method of measuring solar radiation, which is less accurate but also less expensive, is using a sunshine recorder. These sunshine recorders (also known as Campbell-Stokes recorders), measure the number of hours in the day during which the sunshine is above a certain level (typically 200 mW/cm 2).
Incident solar radiation values are based on two primary components: Diffuse radiation that is both scattered by the clouds and atmosphere (diffuse sky radiation = I d) and the ground in front of the surface (I r). This is always measured on a horizontal surface. Sky conditions affect the intensity and distribution of solar radiation.
