We all love using hot water but the way things going we will really have to be smart about how we use it Hot water is the biggest user the energy in the house And energy continues to be one of the biggest costs in the household budget. But don't worry I can show you how you can save energy and money at the same time Solar hot water uses the sun's energy to heat the water So by simply converting your gas or old electric hot water system to solar, you could save as much as 50 to 90 percent.
Of your hot water energy use. Solahart is Australia's leading solar manufacturer For sixty years they've manufactured and supplied over one million solar hot water systems in Australia and overseas. Each unit is designed to maximize the draw on the sun's energy heating the water which is circulated through to the storage tank When it comes to choosing the solar hot water system that's right for you there are two main options. The first one is this roof mounted tank and collectors unit which is often referred to as a thermosiphon system.
The second option is a split system where the tank is located in a convenient position on the ground and is connected to collectors positioned on the roof The basic solar hot water system cost around five thousand dollars to purchase and then to install There is still a government incentives scheme up and running around a thousand dollars off the price of a solar water heater and this is usually given as a point of sale discount to reduce the upfront costs Contrary to popular belief often the best time to replace your gas or electric water heater is when it breaks down.
That way you're investing the cost of a replacement conventional water heater into a water heater that pays for itself over time and Solahart has a emergency replacement units which insure you still have hot water in an emergency situation while you wait for your solar water heater to be installed Its estimated that by changing to a solar hot water system you can reduce greenhouse gas emissions by up to three tonnes per annum and that's the equivalent of taking a four cylinder car off the road Can you imagine if we all did that.
Solar City, Halifax Regional Municipality, NS 2015 FCM Award Winner Energy
Graphic FCM logo, 2015 Sustainable Communities Awards, ENERGY, Halifax Regional Municipality, NS, Population 400,000, Solar City Interviews with some supporting tutorial, as described gtgt Mayor Mike Savage, Halifax Regional Municipality, NS Solar City is a program that allows the municipality to partner with its citizens to bring more solar power to the city by allowing people to put solar panels on their house and pay for it over time. There's no cost to the municipality and it obviously makes it more affordable for people in Halifax to use solar power.
Gtgt David Dahms, High Hopes Housing CoOp We started an environmental sustainability program about 5 years ago in this Coop. When Solar City came around, it was if they had heard our cries for the opportunity to help leverage our energy and our drive with a bit of financial assistance to be able to do something even larger. gtgt Julian Boyle, Manager, Strategic Energy Policy and Initiatives PACE is Property Assessed Clean Energy. It's a 10 year loan that's attached to the property. gtgt David Dahms, High Hopes Housing CoOp The way it's been rolled out, built into.

Outback Flexmax 80 Whats Inside
Hi, this is Josh from Wholesale Solar. I wanted you guys to get a look at this system that I'm using here in the garage. Keep some of the loads in my house backed up. I wanted to focus today on the Outback Flexmax 80. Not necessarily what it can do, more what's inside it because there's a few different things about it that I mean you really just can't get from logging on to the website. so I wanna start by looking at what we've got inside here. I haven't.
Got a camera man other than myself, so I'm going to see if I can kind of position this here for just a sec without being out several hundred dollars for a new iPhone. I want to open a couple of things to show you guys just a couple of things here. The bottom portion of it is going to be where we've got essentially the input from solar or load and output to the battery bank. Okay, awesome! As we can see, we're snoozing so here's the guts of this bad boy. Realistically at its most basic level.
We've got positive and negative in from solar, positive and negative out to battery bank. I mean keep it nice and simple. We see over here we've got a temperature sensor plugged in here. We've got an accessory here we could plug a mate in there, be able to have something remote. There's not really a whole lot else going on here to be honest with you. There's a 12 Volt auxiliary output that not a whole lot of people know about that lives right here. This will send 250 Miliamps, 12 Volts out to activate a relay or.
Things like that. It's kind of interesting. Let me put you back over here and i want to take the top off and show you what makes the Flexmax 80 the Flexmax 80. And if it's up here, now some people mistake this for just an added heat sink which in all technical terms it's not really what we find inside of here just a couple a different, got to push in on the side and it pops right off here. This is a fan so here's the fan and basically here's a little piece of plastic.
Outback FM80 and FM60 Reset and Voltage Set Points
Hey this is Josh from the Tech Department at Wholesale Solar. And I wanted to just take a second and show you guys how to do a hard reset on an Outback Flex Max 60 or a Flex Max 80. And it''s a relatively simple procedure. You can have to do this when you go through and reset your battery type, your system voltage, few other things. Relatively easy, we're going to use the softkeys they're not well labeled anywhere actually but there's one, two, three and four in respect to the diagrams they show in the manual.
And what we do to do a reset is hold down buttons number one and three and supply power back to the unit. So we're going to go ahead and turn it on here. It's going to ask us to select a version. We're going to go ahead and go with English. It's going to ask us for a password. Now the default password on the FM 60, MX 60, FM 80, all the Outback equipment is going to be onehundred and fortyone that's 141 so we'll get that typed in here.
We're going to go enter which happens to be soft key number four. We're going to go yeah we want to do English. We sure Yeah. It's going to ask us system voltage so we'll jump in here. We're actually doing a twelve Volt systems so we'll just hit enter. Happens to be soft key number three. Are we sure Yeah. Awesome! So we get to here there's only one other adjustment that we really need to make and we hit soft key number one to do kinda the initial setup. The first thing I want to look at is going to be.
Charger and that's really the only thing that I suggest people go through and look at. Depending on the battery type, we'll hit go and this is going to allow us to adjust three things current limit, absorbing and float. Now this is an 80 Amp controller it's set at 80 Amps. We can't turn it up higher than that. We can turn it down lower, it doesn't really make sense, so let's just leave it at 80. Now on the absorbing 14.4 is an okay default set point. Each battery is going to come with a different spec from.
The manufacturers as far as where you want it to be. 14.4 will work here. As far as float goes, on my system, I'm using AGM batteries, they're the UPGs. Goes 200 amp hours, 6 Volts. Now the float on a lead acid battery is going to be a little bit higher so default is at 13.6. With my AGM batteries i'm going to need to turn that down a little bit. They want to float at 13.0. So I'll go ahead and set it there. Go back out, we're done, we'll hit exit, we're back to the main screen.
Energys Biggest Disappointment This Past Quarter
Sean O'Reilly We've already talked about a few companies that surprised you guys on the upside, flirted a bit with Shell any other companies that disappointed you and made you rethink your previous bullishness Taylor Muckerman This one didn't disappoint me to the fact that I'm rethinking my bullishness, but I was kind of caught off guard in the negative aspect of SolarCity. O'Reilly How did I know you were going to go there Muckerman Down big. I think Friday O'Reilly 20, right Muckerman Yeah. Not because it had anything terrible to say, they're just changing the.
Strategy a bit. They're actually going to be profitable rather than growing like wildfire. They just had so much growth priced in and I think the fact that people probably saw that they're trimming their growth forecast and then forgot about the fact that they're planning on being cash flow positive for the first time. I think that's a benefit long term. Unfortunately, this company has been a giggitygrowth stock since its inception. O'Reilly Wall Street wants free cash flow generators. Why are they Muckerman Fools love free cash flow. That's what we want. Long term I'm still very bullish.
On this company. O'Reilly You are Okay. Muckerman I saw where they said they've installed more solar installations than the next 70 competitors combined. They're doing something right. They're going to continue to growth. They're not abandoning growth. They've stated they're preparing for the reduction in the investment tax credit at the end of this coming year. O'Reilly I'm kind of surprised that's going away. Muckerman It's going form 30 to 10. It's still not nearly as meaningful O'Reilly That's a 66 hit. Muckerman Yeah, because it's only a 10 tax credit. They said that sales is getting more.
Costly because of competition so they're going to focus on reducing the cost of making a sale and focus on lower cost sales and also focusing on the commercial market, which they're only about 8 of right now. They're expanding into new markets, they're just not focusing on residential growth as heavily. Tyler Crowe Like you said, one of the things that was a big red flag for investors, or Wall Street, or whomever O'Reilly Day traders. Crowe Whoever you want to say it reacted so negatively to their release was the fact.
That, if you look at their cost per watt development sales, general administrative costs over that quarter had grown substantially to the point where it was starting to hamper profitability. If you look at the cost per system, the amount that it takes for installation, the procurement of the solar panel system that has gone down rather impressively and has actually beaten their goals so far. However, the fact that their sales had gotten so high Muckerman They were doing a lot of hiring. Crowe Yeah. The cost to acquire was getting to the point where it didn't make as much.
Sense to grow at gangbusters. To be fair, one of the things when you look at their growth targets previously I believe it was somewhere in the high 60s per year O'Reilly And this is just investor presentations, they broadcast it, and yeah. Crowe Yeah. Their compounded annual growth rate they were anticipating was in the 60s. What they had been doing previously was 100. Muckerman Yeah. They'd been doubling over the last five years. O'Reilly But we're still talking about tripling your size every two to three Crowe Right. They've cut from high 60s down to 40. Let's be clear here 40 year over.
World Energy Consumption OCED and Non OECD
Here we're looking at a graph, two graphs, of world energy consumption in quadrillion Btu. On the left side we see OECD member status. That is, looking at countries in terms of whether they're a member of the OECD or not. And you can shorten this down to say, well, looking at energy consumption in terms of whether countries are developed, or developing, or somewhere in between. Notice that OECD countries, from the 1990s through projections through 2014, have a relatively modest growth in their energy consumption. It's not plateaued but it's certainly not.
Very steep. If you contrast this with the nonOECD countries, we see a much steeper projected growth, especially as the 21st century matures. This is where the energy consumption is expected to be the most intense. These countries, especially led by China and India, are going to be consuming ever greater quantities have energy than they ever have before. And this means that the OECD countries and nonOECD countries are going to be competing essentially for the same energy resources, whether they're nonrenewable or renewables. This graph brings into question, then,.
Issues about energy security and whether or not there's going to be enough distribution networks and enough resources to keep prices relatively affordable for most of the world's people. If things get difficult to move around, or prices get too high, then economies will suffer, and if economies suffer, then politics can suffer, and we don't want to go down that road. So planning ahead is, you know, planning to succeed. So when we're looking at this, energy analysts say, well, we've got to prepare for a time when the nonOECD countries are going to be consuming.
A very large portion of the Earth's energy resources. On the right hand side we've got energy consumption, or world energy consumption, by fuel type. And notice here we've got liquids, coal, natural gas, the renewables, and nuclear power. So we've got a combination here of nonrenewable, as well as renewables. The liquids are going to be following the same path in terms a projected consumption that coal, natural gas, and renewables do. Notice there's no slacking off here, they're all rising relative to 2010 levels. Coal takes a projected dip here, by 2040, but not much.
Generate Electricity with Peltier Module The Seebeck Effect
Hi Gang! I'm going to show how I used this Peltier module, and some cold and hot water to generate electricity. Here this LED is being brightly lit by it. I found my Peltier module in this hot and cold water dispenser. I opened up the back, removed the fan, and the heat sink. Stuck to the back of the heat sink was the Peltier module. How do you use it Apply heat to this side and cooling to this side, so that there's a temperature difference across the two sides.
When you do, electricity will be made to flow through the wires. This is called the Seebeck effect. You'll be generating electricity. Here's a very simple way to test it. I cut some short pieces of aluminum bars which I got from Home Depot. I clip them to either side of the Peltier module. I then get two plastic containers and put the aluminum bars in. I do it in such way that the aluminum in contact with one side of the Peltier module is in one container, and the aluminum in contact with the other.
Side of the module is in the other container. Next up is to measure how much voltage and current it can produce, with no load. I hook up a meter to the Peltier module. I then put cold water in this container, add a little ice, and put boiling water from a kettle in this container. By doing this, the heat from the hot water rises up this aluminum bar, through the Peltier module, and down this aluminum bar to the cold water. As the heat moves through the module, you can see the electrical current rises.
Switching to the voltage setting, you can see the voltage also rises. The highest current I see is around 143 milliamps and the highest voltage is around 854 millivolts. Around this point the cold side is still cool and the hot side is too hot to hold a finger on. Time to generate some electricity to power this LED. I first try by just connecting the LED. But even after putting in fresh cold water, ice, and hot water, and waiting a little, that isn't good enough to light this LED.
That's where this circuit comes in. It's called a joule thief circuit. Here it's being powered by a battery whose voltage is so low, it's considered dead. The joule thief stores up the power from the battery and once it's built up a bunch, it dumps it all at once into the LED in a quick, more powerful burst, enough to provide the needed voltage and current to light it up. And then it builds up some more and dumps it again. The LED is powered only during the powerful bursts, but it looks like it's always on.
So I connect the joule thief circuit to the Peltier module. I again put cold water, and ice, in one container and boiling hot water in the other. Sure enough, 12 seconds later, when enough heat has made its way up to the Peltier module, the Peltier module is generating enough electricity to light LED, with the help of the joule thief circuit. As time goes by more and more heat moves from the hot water to the cold water, warming the cold side and cooling the hot side. And after 15 minutes and 21 seconds.
The Peltier module no longer puts out enough voltage and current, and the LED no longer lights up. One last thing. The Peltier module I found in the water dispenser is a TEC type, a Thermoelectric Cooler, designed for cooling, not generating electricity. It can handle only up to around 100 to 110 celsius or 212 to 230 fahrenheit before being damaged. For serious electricity generation you'll want a TEG type, a Thermoelecrtic Generator. They can handle up to 200 to 300 celsius or 400 to 500 fahrenheit and put out much more power.
Well, thanks for watching! See my channel, rimstarorg for more tutorials like this. That includes one where I use this same Peltier module, but in the opposite way, running electricity through it to freeze water and doing some efficiency testing. Another tutorial where I show stepbystep how to make the joule thief circuit I used to light the LED using a dead battery. And for variety, one about how fast an electron and electricity move down a wire. The slowness of the electron may surprise you. And don't forget to subscribe if you like these tutorials,.
