Table 2: Summary of extent of land at villages.

Topographical analysis has been done considering the 5 meter contour interval and

drainage network of the above mentioned villages and found that out of 64,343 acres

available, about 12,000 Acres of land will be useful for solar park after leaving forest land,

village habitations, streams and wind turbines.

However, the exact village wise land extent and land classifications for the project can be

known by detailed survey and digital mapping.

Water Source:

There are no major reservoirs available near the proposed site. There are water tanks

(Cheruvu) in and around site. Water can be sourced from these tanks. However, detailed

hydrological studies to be carried out to estimate water availability.

Topology:

From the contour drawing it is understood that land available in the above said villages

are mostly plain with streams towards east side.

Contour map of the proposed site is given below:

Energy Estimates:

For the proposed Ultra Mega solar park area, annual energy production has been

estimated using PVsyst 7.0.5 simulation software for multi-crystalline PV modules of REC

Solar 350Wp and irradiation data from Meteonorm 7.3. The table below shows the

simulation results of Annual energy production.

Table 3: Annual Energy Generation Estimates of Obuladevacheruvu site

The annual CUF for typical 100 MW block of solar park at P90 is estimated at 20.94% per

year with the annual generation of 1,82,948 MWh which is matching with the generation

results of existing solar parks in the state of Andhra Pradesh.

Conclusion:

From the initial study, it is found that the proposed site at Obuladevacheruvu is best fit for

setting up the Ultra Mega Solar Park.
