With solar energy being abundantly available in most part of the country, grid connected solar power plants are assuming increasing importance. Energy fed into grid by a solar power plant depends upon seasonal variation of the solar resources, system losses, and losses due to condition of the grid. This paper presents performance analysis of solar power plant installed in Madhya Pradesh. Daily and seasonal variation in the solar power plant output are shown using monitored data, the SPV generation in relation to load duration curve of substation is observed. Since the cost of electricity generated from solar is still expensive and also the power from renewable resources including solar is infirm power, large scale development of renewable resources did not take place and distribution utilities are also least interested to purchase power from renewable sources. This paper provides an overview of...

Taking in to account the temperature and sun’s irradiance, the PV array is modeled and its voltage current characteristics and the power and voltage characteristics are simulated. This enables the dynamics of PV system to be easily simulated and optimized. It is noticed that the output characteristics of a PV array are influenced by the environmental factors and the conversion efficiency is low. Therefore a maximum power tracking (MPPT) technique is needed to track the peak power to maximize the produced energy. The maximum power point in the power–voltage graph is identified by an algorithm called perturbation & observation P&O) method or Hill climbing. This algorithm will identify the suitable duty ratio in which the DC/DC converter should be operated to maximize the power output. The results confirm that the photo voltaic array with proposed MPPT controller can operate in the maximum power point for the whole rang...
