Abstract: Houses large solar power panel required. This is long term investment so understanding impact from climate change. power generation from pv power plant is strongly determined by short term availability of clouds .and it’s depends on geographic condition Therefore, it is necessary to concentrate our forces to reduced the appliance cost. To increase their performance. This paper presents solar energy generation through solar panel in cloudy or hazy day. Using maximum power point tracking technique and automatic solar tracking system.MPPT is needed to maximize the generation of solar energy.MPPT technique to operate the photovoltaic module in a manner to Take out the maximum power from the system. Mppt can be achieved by modifying the output voltage and current. MPPT is effective during cold weather cloudy or hazy days. Solar tracker are device to orient the photovoltaics and other optical devices toward the sun. Sun position in the sky changes with the weather, climate change and time of the day. Trackers are used to collect maximum intensity on solar panels to the maximize energy generation.
