Solar Home Basics : On Grid vs Off Grid Solar Panels


You may have heard the words grid-tied on grid or off grid. These are important concepts in solar energy. In this video, I will explain these concepts and introduce some of the basic components. Finally, I will show you some of the economic differences as well. First is the grid tied system also known as on grid the grid supplies electricity from your electric company to your home, has 110 volts of power to get solar power into your grid connected home.


You would need solar panels installed in the loop of your home and utilize. The grid tie inverter a grid tie inverter takes a DC current, which your solar panel daring and Carissa to AC current, which can be used in your home. This is one of the cheapest and most efficient ways to fire: a home with solar. The other option uses a system called maximum power point tracking, also known as MPPT. This system uses more elements in the system seen before.


First, the solar panels convert sunlight into DC power. That power goes through a charge, controller to then charge a bank of batteries, those batteries feed an inverter which turns the DC power to AC power or alternating current to power your home. However, every time power goes through a device, there are losses. Some power is lost, as it goes from a solar panel with charge controller. Then it goes to a battery which is resistance.


Therefore, more loss more losses again, as it comes out of the battery into another inverter and finally, to your house. There are losses in every step before the power reaches your house, making the system less efficient for the most part. If you don’t need batteries it’s best, not even because they are not cheap and last for three to five years, unless you buy an expensive set of batteries which can last fifteen to twenty years, you would want batteries in places where you may get many power outages. If the grid fails and as a backup or for cloudy days, the best option is to have a big bank of solar panels and a grid-tied inverter, so that any excess power can be fed back to the grid for credit to use when needed. The solar panels have to be well connected, but if any of them is shaded or not, 20 correct to the Sun and can draw out the whole system.


But if you use a micro inverter in each solar panel, if you have a problem or failure with one solar panel, rest already can function correctly. Second is the off-grid system. An off-grid system is where you don’t have the grid feeding your house generally speaking. If you have a farm or vacation home in the woods or up on a mountain, it will cost a good amount of money to bring the grid to your home. It would be far more cost efficient to power a home using a solar system with an off-grid system.


You need to be careful, as you want to power your home with solar and efficiently as possible. You need to carefully calculate what your power requirements are, because there’s no great to fall back without the grid. You need to fully understand and calculate the power requirements for heating, cooking and entertainment needs I’ll. Try to make them run as efficiently as possible being more efficient. In your home will save you money three times over.


The reason for this is because any extra power you need has to be accounted for by using additional panels, potentially a bigger and rivet or charge controller, and then allows your battery bank. It is much more economical to make your home run more efficiently to spend extra money and three extra places to provide a necessary fire for your home. An off-grid system to potentially run far more efficiently as most grid connected systems have to make accommodations electrical appliances running off 220 volts. In addition to those efficiency in going through charge controllers batteries and in your off-grid system, it’s best to have a solar panel screen power through your chart control. This is essential because you need to control the amount of charge that goes into your battery pack.


An MPPT charge controller makes the collection of power from your solar panels a much more efficient once you have the power coming into your batteries, to potentially have the option for an off-grid system to run your household off of a 12 24 or 48 volt system. If you have a total system, you can potentially power your lighting directly from it. This would be no more inverting making a far more efficient use of the power coming from your batteries. Of course, you may have to introduce them vertically. You can partially run some things off with 12 volts, as well as some appliances or entertainment systems which need 110 or 220 volts.


So there you have it on grid vs,

Off-Grid just remember, on-grid is much more economical and usually the way I recommend you start after. It is more efficient, but is most useful if you do not have access to the grid, use our website solar, flexkom, to calculate the cost of solar for your home or call us for a free consultation with so long here.
