Solar Panel Systems for Beginners – Pt 1 Basics Of How It Works & How To Set Up

what's up youtube this is LTS Reliance today I'm going to do a video and show you a very low level beginner's level way to hook up a solar panel system I'm gonna try to make this uses little jargon and dumb this down so that anyone can understand how this works it's really not that complicated obviously in any system the first thing that you need is going to be a solar panel in this case I just have a small 10 watt solar panel for demonstration purposes but they range in size dramatically they can be as big as a door and then they can obviously be small enough that you could mount in in inconspicuous places like this one the first setup there's two different types of setups out there there's a grid-tied setup and then there is an off-grid setup this the first one we're going to go over is an off-grid setup basically the main difference is that you're going to be charging batteries to store the power instead of using the power on demand so in this in this case you need to the the power source is obviously the solar panel and then you need it connected to a charge controller this one is just a cheap one that I you type play with for for testing purposes so each one will be labeled it's very easy to understand very straightforward but it has a little picture of a solar panel here and you connect the red wire which is positive to the positive and the black wire which is negative to the negative there's only two wires in a direct current system like this this is a DC system not AC like like your house uses and it is also most solar panels are only 12 volts well the the easier the beginner ones are are only 12 volts so you connect the input here and then the next picture is for a battery and here I've got a battery you need some storage medium a way to store the power so you will hook up the charge controller to to the battery again the red is positive and black is negative okay so now that's connected now we have we have power the third part is for the load now a load is just a term for anything that you is going to use the power in this case I'm going to demonstrate with a computer case fan since it's 12 volts just for easy demonstration purposes so obviously it's powering we don't have any sunlight on the panel so it's using the battery the stored energy and the battery to power the the load or the fan in this case now you can have many you can have bigger batteries than that you can have smaller batteries in that you can also hook them up with multiple batteries in series which is kind of like how a flashlight works you put multiple batteries inside the flashlight and they're connected end to end and they provide the power for the flashlight and in this case you could connect these and to end and create a larger power source more more power to draw on I'm going to leave that explanation in more detail in a different video but for this purpose this is all it is is literally is that simple you've got a power source you've got a device that allows that power to to kind of move in between devices basically the excess power can go into the battery and charge it and then the load can also be powered from either the the solar panel or the battery or both very straightforward system this is once again this is called an off-grid system the next type of system that we have is a grid-tied system or an inverted system basically what we want to do here is we want to take the power source the solar panel and we want to convert it immediately into usable energy and houses use alternating current we use a 120 volt alternating current in the United States so this is just a cheap inverter again that I use for testing purposes and it will convert the DC power from the solar panel into useable AC power and you've got your you know your normal wall plug type plugs they also usually will have a USB plug where you can charge a cell phone or or whatever else so all you need to do for this setup there's really no other devices at all you simply have the inverter and you have the solar panel and you just again you connect the red wire to red and the black wire to black and that's literally it now obviously a grid-tied system needs to be installed by a professional you do not want to be working with AC power DC power is not very dangerous 12 volts is not very dangerous if you make a mistake you're not gonna burn your house down but if you make mistakes with AC power that's bad and also it's probably illegal to do so and obviously there's different types of inverters this is just a cheapo inverter there are also more sophisticated inverters this one is a pure sine wave inverter which means that this one will actually be able to run sensitive electronics without damaging them these kind of have a dirty sine wave power they're kind of squared off and so they won't do very well with things like flat panel TVs and and and computers and things like that so these are much more expensive but they will have much cleaner power and they're they're safe to use though the third one which I I can't show you but is a grid-tied inverter which basically means that it will tie into the electrical grid of your power company and it will power your home or if you don't need that power it will sell that power back to the electric company for a certain amount of money these these are a little bit less common for obviously for beginners because there's one there's no way of storing the power and two it takes a professional to install it in three it's prohibitively expensive at least to get started so just wanted to show you conceptually what this looks like and explain how it works I don't have this isn't in sunlight so even if I connected it I wouldn't you know I wouldn't be able to show you but basically converts 12 volts DC into 120 volt 20 volt AC so that you could plug your TV or your computer or whatever you wanted into it and it would work hopefully this kind of helps you understand a little bit more about how to connect a solar panel system hopefully it was a beginner level enough for you guys if you have any questions feel free to ask thanks for watching
