சூரிய ஒளி மின்சாரம் (Solar Electricity)

The completed Solar Panel mount structure.

Bottom side view of the panel.  The Panel is fully resting on the Iron frame constructed in the nearby fabrication shop based on my design.

This is my assistant Aakash, the boy next door.  He has been my aide for all the mechanical and automobile works.

The base frame of 30″ x 21″ with the center piece at 15″.

The base frame from perspective projection.  The center piece is a 5″ x 2″ 10mm plate welded at the center.  The holes are 10mm diameter drilled at 1″ and 3″ from the top and centered.

The main load bearing vertical pole measuring approx 2m and 2″ diameter.  The base plate is 6″ in horizontal length and 6″ on vertical depths.  The holes are 1/2″ and drilled at 3″ and 5″.

This is the solar panel bought from Akshaya Solar Pvt Ltd, AP.  The panel is rated 12v 70w and of dimension 1200mm x 21″ and weighting approximately 5kg.

The swing arm connecting the base frame and vertical pole.  The holes are 10 mm diameter and punched at 1″ and 3″ from the top.  The bottom pipe is 2.25″ diameter and about 5″ long.  The cross bolt is 0.5″ diameter.  This swing arm mounts on the pole on one side and attached to the base frame on the other side.  The base frame is pivoted on the top hole with swing setting using one of the 3 bottom holes.  The positions are provided to compensate of uttrayanam (north bound sun movement) and dakshanayanam (south bound sun’s movement).

The bottom link of the vertical pole.  This U link attaches to the parapet wall, which is 6″ is width and the cross bolts pass through the wall to lock the vertical plates.  The horizontal and the vertical plates are 6″x2″ and 10mm in thickness.

These are the bolts used.  The 1″ (4 nos) bolts are used to secure the solar panel on the base frame.  The 1.5″ bolts are used to secure the base frame to the swing arm.  The 4″ bolt is used to secure the swing arm to the vertical pole and the 8″ bolts are the bolts to secure the entire unit on the parapet wall by passing through the wall.

    I like your posts related to PV Solar a lot. Have you been able to make any progress with thermal+PV solar panels?

    Not yet. As it involves a lot on fabrication, I am yet to venture into that. But, I will soon implement it. Thanks for your support.

    Hi Sudarsun,
    Since you have installed your solar panels a more than a year back, could you let me know how it has been performing in general? Is there any drop in generated output? If you had to assemble/install the unit today, would you change anything? Thanks – Raghavendra Sondur

    It is working pretty well. I don’t see any drop in the power produced. if i had assembled the unit today, i would not changed much, except for making it dual power instead of pure solar powered. Also, the prices of panels have dropped a lot. When i bought it it was roughly 70Rs/watt but now, the price has come down to 50Rs/watt. BTW, I have also installed a 6kW power plant in an academic institute in the neighborhood.
