The solar industry is very, very focused on improving efficiency and reducing the cost. Our attempt here with this research is to propose a new way of looking at these structures and saying, well, you can use existing materials and nothing really needs to change very much. You just shape them in different ways that gives you this benefit. Kirigami is a Japanese art that's related to origami where origami is really about folding of things and kirigami is about cutting things. A colleague of mine who is an artist, Matthew Shlian, he had some interesting.
New shapes and when you pulled on the sheet of paper the cuts would sort of begin to buckle and deform in a very controlled way and so I realized at that point that we could look at that structure as a hyperminiaturized version of solar trackers. Conventional solar tracking has been used for many, many years. The mechanism itself cost quite a bit of extra money. What people end up doing as they say, well, since the mechanisms gonna cost all this extra money. we might as well put a really big panel and then eventually you end up with.
Something that's really big and really heavy. When you think about putting this type of thing on a rooftop it's very very difficult and in most cases is just purely impossible. It was a fairly lengthy process because the things that you do in paper don't automatically translate to other materials and so I started talking to my colleague, Stephen Forrest, about using some of their very high efficiency gallium arsenide solar cells. They're pretty thin, less than 2 microns thick that's ten to fifty times thinner than the thickness of a human hair. What the new design allows us.
To do in contrast to conventional tracking is it basically allows us to work with the same form factor. It doesn't catch the wind, it doesn't weigh any more than a conventional solar panel might and the thing that it buys you is that you can use less semiconductor to gather the same amount of energy. A third less material to generate the same total amount of energy that you would otherwise. Which means that in turn that I could decrease the cost of installation because there are fewer panels to install but you do require little bit of extra area. When you.
Multiply it by the total number of solar installations it's kind of like a billion dollar value proposition potentially. I guess it looks simple enough, kind of like something that you could do on your kitchen table, things don't have to be complicated for them to work. If this can be shown to be quite reliable, then the net benefit could be quite big. V.O. These candies which are already pretty soft should be about 10 to 100 times stiffer than the silicone. So the material that we're working with in the lab is really really soft.
Lights dim for interests in solar panels
Hawaiian Electric's proposal to expand residential solar installations comes at a higher cost for some. Has that plan dimmed the interest in solar KITV 4's Paul Drewes stopped by this weekend's building industry remodeling expo to find out. There's a lot of new things at this year's Building Industry Association of Hawaii remodeling expo. 1300 shot of guy opening shoji screen A company in the islands is once again making shoji screens, 400 shade opening or closing There are sun shades that can open or close in a second.
1642 kumu kit solar setup And hot water tanks now come with their own solar power. But what is not new is the interest in putting photovoltaic panels on people's roofs. richard lee honolulu resident14291438 that's where energy is going, cheaper, doesn't harm the environment blake618630 There's a lot of interest, everyone knows the product is reliable. The dollars and cents of it is still advantageous. The spirits have just been kind of broken of the consumer by HECO's rules Hawaiian Electric recently came out with a new set of.
Proposed rules regarding residential solar connections. Delays in the plan have meant a backlog of completed installations waiting for HECO approval. It also meant some residents have turned on their systems without first getting that approval. blake726 the market has decided that PV is a better investment than paying a bill to a company that doesn't seem to have your interest at heart On Friday, HECO came out with a warning to those who are improperly connected. Pull the plug or else. graphic goes here Hawaiian Electric says, after sufficient notice, if a customer.
Does not disconnect the PV system and notify Hawaiian Electric, PUC rules give the utility authority to shut off the system and lock it to prevent interconnection until technical checks confirm it is safe. standup2905 while HECO cites safety as the reason for the shutoff, it also claims unapproved connections are hurting some solar companies david thompson alternate energy2323 HECO is claiming that because those folks are connecting without approval and that is actually holding up the process of them doing these studies, so it really hurts the folks that are waiting and.
How MPPT is Beter Than PWM Solar Charge Controller SuKam Comparison Kit
This is the comparison kit of SuKam PWM versus MPPT solar charge controller. This kit has two channels and each channel has four meters. In four meters, the battery voltage, battery current, solar voltage and solar current are displayed. For example, let's first take the PWM charger. In the first channel, PWM charger is connected which is connected to 12V SuKam Bazooka tubular battery of 15 AH. In the second channel, MPPT solar charge controller is connected which is also connected to SuKam's Bazooka 150 AH, 12 V tubular battery. As we can see.
In the demo tool kit, both the charge controller has the same input voltage which is 17.4V. This means we have applied 17.4V to PWM and to MPPT charger as well. Now we will switch the battery on. Now we have connected the battery to PWM charger. Its battery voltage is 12.5V which is displayed in the panel. Similarly, now we will connect the battery to the MPPT charger. The voltage is displayed as 12.4V. Now both the chargers are on. Now we will check the readings on the comparison kit. First we will check the readings of PWM.
Charger. As you can see, solar voltage input has decreased from 17V to 13.7V and the battery voltage is 13.3V. Solar input current is 9amp and the battery input current is 8.9amp. Now we will check MPPT. In MPPT, the solar input current is 9amp but the battery input current is 11amp. Here we can see there is a boost in the current. At the same time, solar panel voltage is the same as applied before which is 17.4V. We can see from this demo that MPPT boosts the current in the battery.
solar panels installation on flat roof
Hello everyone, my name is Steve and welcome to aquaheat.uk. Today we are showing you an installation of solar panels that we've done. This is a solar panel system that provides hot water for the property. On this particular installation, we fitted two landscape solar panels on to a flat roof and they're staggered one behind the other. We've got one here and then we have another one here. They're both connected by this pipework here, it goes down, through the roof into where the solar cylinder is we can talk about.
That afterwards. So normally on these panels on a flat roof, they do sit side by side. On this particular installation to comply with local planning, they've requested that they've been fitted one behind the other, which we can do. With reverse style solar panels you can fit them on a pitched roof they'll either be on the roof or you can fit them mounted. This particular one is landscape, you can have portrait, which is like a portrait picture basically. This particular one is a Solar Worcester Bosch FKT1W. This is a.
More high efficiency solar panel, than the standard panel they do and it soaks up more UV's from the sun because of better performance. You will even find on days like today, where it is a bit cloudy and overcast that there is a lot of UV's around and you can still heat up hot water even on days like today. That's about it really it's quite a simple installation. We fit the frames, we assemble everything. We fit the solar panels in, run the pipework lagging in, it's wired into a sensor, which we've done. The next stage is.
PT 100 MPPT Charge Controller by Magnum Unboxing Features
Hi this is Amy from the altE store. We're going to do a quick unboxing of the Magnum Dimensions PT 100. This is the first 100A MPPT charge controller on the market very exciting. So let's take a look at what comes with it. So we have got a 6' network communications cable, a 6' extension cable, in case you need to go more than the 6'. The battery temperature sensor very nice to have because it does temperature compensation for your charging, so it's really good to have an accurate reading of the battery temperature so that it can adjust. It's.
Got a ground fault warning label, which is required by National Electric Code and the mounting screws to mount onto the back plate. Now this back plate is nice, it actually will mount right onto the wall and then the charge controller will mount on to it. So let's take a look at how that works out. And we've got the nice manual always read your manual! So let's take a look. Ooo! So, this is a 100A charge controller you can put up to 6600 watts into it. Now, take a look at.
This really nice design and we were talking about the mount for it. So you can see it's just going to mount right onto here and it gives you a nice air flow for taking care of the heat. So it does have two fans internal, as well as with this nice air flow, helps keep it really cool when its managing those hundred amps so the front of it very nice it's managing those 100 amps. So the front of it very nice. It's a nice simple design here.
We've got the LED display that shows the PV array, volts in, and kilowatts. It's got the battery bank, volts and amps. And then it gives you a couple of LED indications of what stage it's in. You've got your bulk, absorb, and float charging. You've got a fault indicator and then auxiliary if if something is using the auxiliary port. Then you've just got two buttons, one to select the feature, one to reset and then two if you're going to do equalization on flooded batteries. So it does have nice knock outs for you to get your cables in and out. And this bottom.
Part comes right off so that you've got all of your wiring right down here and this all stays up in place. So really nice, it actually has both arc fault and ground fault protection so you've got a really nice safe install. Nice thing about it is a lot of charge controllers, MPPT charge controllers, only go up to 150 volts temperature compensated. This will actually go up to 187 volts. So what that lets you do is you can actually put three 24 volt panels in series going into this, or four 20 volt panels. So that's more than what you can.

Using Lasers to Create Superhydrophobic Materials
A couple years ago, my lab created a technology that turns a variety of materials superhydrophilic. Superhydrophilic means it actually attracts water. We actually turned the surface hydrophilic to such a strong degree that water runs uphill against gravity. That technology can have many applications on its own. After that, we started to work on the counterpart technology, making surface to repel water or as we call it, hydrophobic. We have been working on creating superhydrophobic material using a laser processing technique. What we see here is pretty interesting. The water falls to wards the surface and is repelled and bounces off the surface. This.
Is achieved by creating a unique pattern of surface structures at micro and nano scales with our laser processing technology and those structures are intrinsically part of the material's surface. Most of the hydrophobic surfaces available today rely on chemical coatings. Our surface has many advantages over the coatings out there. First our surface has a much stronger hydrophobic effect than the coatings and secondly, we don't have to worry about coatings peeling off and the surface degrading over time. Many people think of Teflon as a strong hydrophobic material. However, if you want to get rid of water on a Teflon surface you have to tilt the.
Surface to about 70 degrees before the water starts to slide off slowly. Our surface requires an extremely small angle, if at all, for water to slide off. I think there are many possible applications for this new superhydrophobic surface. For instance, if a surface repels water, you will also prevent icing on the surface, you will be anticorrosive and there's sanitation applications as well. We wanted to create this superhydrophobic surface that will not only repel water but also repels water containing a waste materials. We know in many developing countries in the world, clean water is a scarce resource so if you.
