" Probably have fifteen or twenty new technologies in this house right here and pat has been set up to try to promote technologies and get builders and homeowners understand them better use them. And -- to houses for the next century right this is a great demo of that NASA said we have probably fifteen or twenty I think you're going to be talking about a number of yeah."
" Six obviously the most exciting available. Technologies that whole business of building with. Structural insulated panels but right now we're putting a little roofing product and it into -- it's not brand new but certainly. An interesting thing."
" Well it's it's a major step in innovation photovoltaics. Photovoltaics. Right from the Simon takes for electricity -- have been around for probably two decades. Oh yeah -- I remember putting them -- when it shows fifteen years ago but that was in Arizona. And the cost was Grigory -- and they were also probably large bulky panels were -- exactly yeah we have a brand new product here today from united solar system. To PV shingle. It's a direct replacement for shingles on -- house or in this case on night. Out building a little -- yeah but they go directly in place of existing shingles and you can generate electricity directly from the sun so -- roof and its -- it's a roof and a powerhouse absolutely and let's find out more about how they work OK. We want to go up MC Ren Anderson from the national and wanted to let you know what it them up on the roof right now all right."
" They're not really root for right now -- researcher at the national energy laboratory ideally lab that is a path partner. Okay but here you're onto here like everybody else we appreciate your participation -- little bit about how -- takes actually work. The politics work the light comes in as a photon. It's the photovoltaic which is -- semiconductor. -- some electrons loose and that produces electricity that then goes to the application. And that's like the science guy that it it. And in this house for using a small amount of politics because we're just firing. The battery packs and things for -- tools and children's toys insensitive exactly but in a traditional situation where whole house the photovoltaic array. You'd be generating electricity for use within the house right. That's right thing you can also feedback into the grid -- if you produce more electricity from your potable decorated you actually consume you get solid back to the utility. It's at or at least. Try to. How do you install it. Well and saws very much like irregular single product. Except that it's much wider as you can see because -- one and a continuous strip in the middle of the -- idea and here we've got a combination of traditional. Barbara -- shingles and then we've makes in the potable ticket you're only putting in a small amount. The political day that's right we just putting in enough to -- yet independently. -- pre drilled holes into the room feared the -- back through. OK and at first step is to take the paper here. Just like regular shingle product we have an -- okay. Then now we feed the lead through their. Line it up and that layered beneath it Randall topical layer hold it and you you can for the -- Right in the top that this area here along the along that white line this. Right. Nail about every two feet or just about every two -- yeah. This custom. Get a little bit of a bubble here okay again we're going to pull towards here. To illustrate. Its political and it's rated. At a all right. And we're putting in how many of these we're gonna put an -- of them. In this application that's gonna give us 120 watts of power terrific all right let's get the next one here. OK and then you just take your regular fiberglass. Shingles and married them right into place. And then you can add your next layer of potable -- right. Now how much how much does this cost these these photovoltaic shingles and the shingles asked about five dollars and why. Five dollars a watt yes so you've you've you -- to pay according to how much electricity generate and it's very don't figured in terms of square roofing product you know. It's the only size -- not to cover the respite to provide the right. Now what about the actual storage. By the electricity that you're generating the in this case we have an a and a small Volvo battery inside the sand that -- using the story of electricity output take a look at it I check out how those wires talk connect. You've -- all the wires through. Or mister -- there already. Great stuff is solid electrical. That's right with -- there -- Bob these are all the wires that came through from India collectors and let me show you that regain some power that is the -- did come out. But -- pretty well well. Yeah very much like gay. Automobile electrical system in this case the collectors play the role of the generator in the altered either. Producing power forest. And then. I basically connect these together in series to give me a little bit of voltage to boost for charging the batteries. And then feed these into the junction box."
" And it -- my arm here yet. What you've connected all the we have way. That's correct it and also we have four apparently the building to this junction box which is the is done in direct current site. And the power from the junction box. These incidents voltage regulator. In this voltage regulators and controls detergent process to the battery. And also parallel -- DC voltage into the -- her. In -- converts. Media power and easy to alternating current 110 volt assistant use understand your house okay that gives us the most flexibility for power in -- it. And so we'll have an actual receptacle right there everybody relate to that how much power actually stored in the -- This is that they are in our batteries -- ran one hand for thirty hours thirty hour and it's matched to the overall size of the system here's and in that match between what we need to store. And we're producing. Excellent."
