The spread of solar plant is in various kilometers and monitoring is critical

A failed string may remain un noticed for several months


Foundation bolts design sample


What we are looking for is the structure like this design, which is based on the

Indian available materials


Module mounting sliding structure design in which there no

module clamps required


Lets examine different plant layouts


Inverter placed at Centre


Inverters Placed at periphery

It is important to analyze the DC losses while deciding the plant layout


Layout with Central division

You need to take care of vehicle movement in deciding the plant layout


Layout without Symmetry

It is always better to have symmetry in your layout


Layout without True South

Always keep the module slop towards true south


Plant layout with only Peripheral road

Approach roads and drains should be planned properly


Plant design with symmetry

You will not always get land in north south

orientation. Still you have to manage the

plant layout


Portrait v/s Landscape design

The pitch required in case of portrait is high when compared to pitch in

landscape to decrease shading losses


Structure design
