The Size of the windows on page 26 is 2.1 x 1.2m, so the Glass size may be 1.1 x 2m and I believe they can do that size without a centre Rail.

There is some points missed here by many, so I will highlight the Clinchers so the light bulb switches on for Yas all.

In most places that have power grid supply they also have Supply Charge, then Plus the power use rate charge x the kwh used = your Bill.

But in a stand alone Structure, that has no Grid Connection. The Savings on power isnt Just the rate that a KWH is sold at by the Grid, You have also saved the SUPPLY CHARGE as well. In some cases its half the bill. So in some cases you could be saving double the KWH rate.

Another Overlooked factor, is lets say you are Building a Greenhouse anyway, but you find out about PV Glass. And you were in need of power for your Grenhouse anyway. But now realise if you use PV Glass you get the Power you need, and also after about 4 or 5 years, the power savings start paying off the materials cost you wouldve paid for the structure anyway. So the Power savings pay it off in the years ahead. So it could potentially make the Viability of Building a greenhouse and growing food an even more Viable Project.

There are plenty of ways to time shift power suppy to power need. During the day could pump water up to a higher tank, and at night it waters by gravity feed. And for Lights, they could charge batteries in the day and use the lights as neded on battery at night.

Any surplus day power could be just pumping water into higher tanks, so on days with low power you have high water to gravity feed sprinklers.

There is always a way.
