orientation tilt 15°, Azimuth 0°, and It will be produced maximum system output 139.4 kWh/day as shown in **Table 3**. In this zone solar sun radiation is very low due to wet season is overcast, and the dry season is cloudy weather zone. The temperature

Another, geographical site latitude are 13.09°N, longitude 80.28°E (Chennai), time zone UT + 5.5, and altitude 0 m. The PV module and system installation should be the same characteristics pre-sizing evaluation, and it will be produced maximum system output 136.0 kWh/day as shown in **Table 4**. But, in this zone sun radiation is high. This report delivered the solar output does not depend on the sun temperature. Solar panel is increases heat with the effect of sun temperature, automatically the output current increases. However, the output voltage is linearly decreases. It's directly by changing the rate of solar heat delivered from atmosphere, and earth.

typically varies from 46°F to 74°F, and it is rarely below 40°F or above 80°F.

The results has reveal that maximum region in Indian sub-continental an enormous solar power potential located in an different region, where solar radiations are regularly available in all overt the year (expect rainy or cloud season). Furthermore, PV energy is easy –maintain, cost saving, and high durable. So, in this type of PV energy is more suitable for Indian region with identified maximum solar irradiation under state-wise, assessment of PV power spectrum analysis, PV grid system presizing, and battery management system. Finally, the statistical summary that solar insolation values ranges of 2.9–4.0 kWh/m2 /day to 5–7 kWh/m<sup>2</sup> /day with an average value of 5.9 kWh/m<sup>2</sup> . The important role have been recommended for solar power in order to fulfill the country energy demand. Its way to a future need of sustainable development play major role in Indian sub-continental.
