If you want to learn more about this topic, start your googling with these keywords:
Solar window: a window that functions like an ordinary window but also generates power like a solar panel
Nanoparticle (also called nanopowder or nanocluster or nanocrystal): a microscopic particle with at least one dimension less than 100 nm. These tiny objects often have characteristics that differ from larger versions of the same material.
Quantum dots (QD): tiny nanoparticles of some kind of semiconducting material, only several nanometers in size, so small that their optical and electronic properties differ from those of larger particles. The QDs embedded in solar windows can absorb radiation largely in short wavelengths and re-emit in longer wavelengths; useful for capturing solar energy and successfully transferring it to the solar cells on the edges of the pane.
Total internal reflection: a phenomenon in which a wave hits a medium boundary at such an angle that it doesn’t pass through to the other side

now we know how much load we will have on a typical day being drawn from our solar batteries its time to determine how large of a battery bank we need. the loads are measured in watts while the batteries are measured in amp hours. once you determine if you will go with a 12v or 24v or even a 48v battery bank system its time to figure out how many amps you will need.
match the watts use in a day with the watts in your solar panels however you must consider storms, seasons, bad solar days so having more solar is good.

To get to Amazon just visit my store first and click the link to amazon. it will take you to the amazon home page just as if you typed it in yourself. the only difference is you pay the same but Amazon sends me a couple of cents out of your purchase. : http://arizonahothomestead.com/store/
