Solar PV film roll. Revolutionary new production technology.

Just Have a Think 351K subscribers

Solar PV panels are now a common site around the world and they do a great job. But they only work on flat surfaces. What about the millions of other surfaces that are not so conveniently shaped? That's where flexible solar film comes in. The concept is not new but now a UK company has developed a unique Solar PV film that could make the technology accessible to millions more people in remote off grid areas in developing nations.

Indian State Of Andhra Pradesh To Buy 7 Gigawatts Of Solar Power 🌞

The Indian state of Andhra Pradesh has agreed to enter perhaps the largest solar power purchase agreement with the Solar Corporation of India (SECI).

The power distribution utilities of Andhra Pradesh have secured approval from the state regulator to procure 7 gigawatts of solar power from projects auctioned by SECI. Power will be supplied in tranches between September 2024 and September 2026.

Distribution utilities will supply this power to over 1.8 million farmers for nine hours a day free of cost. Currently, these utilities supply power to farmers at Rs 4.36 ($0.056) per kilowatt-hour. The utilities had earlier planned to procure 10 gigawatts of solar power through auctions. These projects were supposed to be set up a solar power park within the state.

The state government had issued a 10 GW tender in January 2021 and had received bids for 6.4 gigawatts of capacity from a number of leading project developers. However, the tender ran into legal trouble and was eventually quashed.

By procuring power through SECI, Andhra Pradesh is expected to save Rs 2.3 billion ($304 million) in solar park and transmission infrastructure development costs. SECI will reportedly supply power from the 12 gigawatts of solar power capacity it allocated to Adani Green Energy and Azure Power under the manufacturing-linked power generation tender. Apart from power generation capacity, Adani Green Energy and Azure Power are required to manufacture 2 gigawatts and 1 gigawatt of solar modules.

Spherical Solar Cells - doubling the power output of flat PV panels!



Just Have a Think 360K subscribers

Solar panels are highly sensitive to what you might call 'sub-optimal' conditions...wrong angle of the sun, scattered sunlight, dust & sand, too much heat - all these things diminish the panels ability to generate power. But now a research team reckon they've overcome all those problems by creating a spherical version of the common solar PV panel. So, is this a practical proposition for the real world?

Agelbert COMMENT: All good. There is no doubt whatsoever that the eye shape of the fly is more efficient at capturing light than a relatively flat eye shape, which, along with its wings, enables it to survive long enough to propagate its species. However, natural selection being a subtractive process, it is irrational to think that said subtractive process could randomly result in a more efficient eye shape. The fly's eye shape is clearly an integral part of the fly's overall design. In fact, no fly fossils (or flies in million year amber) have been found that don't have the round eye shape (i.e. NO "transitional" fossils). Darwin thought there was no Designer. The evidence argues otherwIse.

If you think Evolution is the best explanation for increasing complexity and efficiency in living creatures, I suggest you take a very close look at the owl skull, eye shape, eye socket and neck vertebra. All these separate biological anatomical parts function as a unit. They simply would not make sense in the absence of a single one of the others. With eyes that are fixed in the head, the head HAD to be able to turn so MANY degrees. The vertebra HAD to be designed to allow normal blood flow during extreme head rotation or there would be no advantage to the fixed binocular eyes and 270 neck rotation. The absence of any one of these "mutations" would have dangerously decreased the owl's predatory efficiency if it had not "evolved" simultaneously, which is statistically impossible in the time frame Owl species had to "evolve".

As an earring of gold, and an ornament of fine gold, so is a wise reprover upon an obedient ear. -- Proverbs 25:12
