SAEL Ltd., a photo voltaic and biomass developer in India, has commissioned a 28 MW (DC) solar energy plant within the mountainous Indian state of Mizoram.

From pv journal India

The Indian state of Mizoram at present hosts a 28 MW (DC) photo voltaic plant, nonetheless the problem of sloping, uneven terrain with slender strips of land separated by ravines. The plant is formed like a hand, with 15 photo voltaic array fingers linked by a fringe street and a 33 kV transmission line.

The photo voltaic park is close to Vankal, Khawzawl district. It covers 194 hectares. Uneven terrain makes it tough to put in photo voltaic panels in a means that maximizes their publicity to daylight. The orientation and angle of the PV modules have to be adjusted to account for the slope of the terrain.

“The plant is formed like a palm with 15 fingers linked to a fringe street and 33kV transmission line for energy displacement to maximise module set up whereas successfully lowering shading,” Kamalesh Saraswat, a SAEL engineer, stated pv journal. “Total, our considerate method to the design of your complete solar energy plant ought to assist us obtain optimum power manufacturing and effectivity.”

By means of its wholly owned subsidiary Sunfree North East Renewable Power, SAEL has signed a 25-year energy buy settlement with the Mizoram authorities’s electrical energy and energy division. SAEL’s in-house EPC workforce carried out the plant set up and commissioning.

Saraswat stated that the primary problem is to determine the plant, in order that the corporate can set up the module mounting buildings and obtain the specified capability of the plant.

“Our workforce performed a contour and drone survey of your complete space to determine flat areas, ravines, and steep valley areas and optimize the angle of the module by our newest software program and instruments,” stated Saraswat. “We additionally observe the pure contour and reduce the steep space to cut back the lack of mismatch/effectivity of the plant.”

Mizoram skilled robust winds and heavy rains, which might harm or dislodge photo voltaic modules, so the SAEL workforce supplied extra structural assist to make sure the panels remained securely in place. The module mounting construction is completely different from standard flat-terrain solar energy crops. The plant has high-efficiency mono-PERC modules and string inverters.
