How many Solar System Configuration Types ?

Tutorial # 3 
There are three main types of the configuration of the solar system.
     1.  Ongrid/Grid Solar System
     2.  Stand alone/ Offgrid Solar System
     3.  Hybrid Solar system
Now I will discuss all the above-mentioned configuration types in detail.
1. Ongrid/Grid Solar System
  Kindly see the below on-grid Solar System diagram.
  • On-Grid Systems are solar PV systems that only generate power when the utility power grid is available. They must connect to the grid to function.
  • These are the simplest systems and the most cost-effective to install.
  • These do not provide power during a grid outage
  •  They provide power to the Load and grid simultaneously. In the day time, these systems provide power to load and grid, and in the night load takes power from the grid. There is a two-way power flow.
  • There are no uses of batteries.
  • The benefit of grid-tie solar installations is that they reduce your reliance on the big electricity companies and ensure that more of your electricity is produced in an environmentally efficient way.
  • One disadvantage of most grid-tie systems is that if there is a power cut, power from your solar array is also cut
2. Stand-alone/ Offgrid solar system
     Kindly see the below off-grid system diagram.
  • These systems allow you to store your solar power in batteries for use at night.
  • There is no grid involve means not you can send solar power to grid neither u get power from the grid in night or day. In this solar system, you use batteries to store power so that you can use this storage in the night.
3. Hybrid Solar system
     Kindly see the below hybrid solar system diagram.
  • Hybrid solar systems generate power in the same way as a common grid-tie solar system but use special hybrid inverters and batteries to store energy for later use.
  • This ability to store energy enables most hybrid systems to also operate as a backup power supply during a blackout, similar to a UPS system.

  1. Great post!! We are a growing business with an ever increasing product range, endeavoring to stay ahead of the pack. To avoid disappointment, it is of the utmost importance that the customers acquire quality products at the outset and that the products are installed by someone suitably qualified to do so Inverters for sale

  3. Before you make a commitment toward purchasing a solar panel system you may want to know more about the different components and how they work together. If you are planning to hire a contractor to install the system, you will know what they are recommending and can make a better decision, and if you are thinking of installing a system yourself you will want to know which components will be right for the job you want to do. The main star in the show is the solar panel, and although there are lots of choices, the panels used for.
