Solar grid system type - Off grid, On grid, Hybrid System types
The major advantage of installing a rooftop solar power system in a home is that it gives you the ability to produce power consistently when the sun is shining brightly and directly on your home. The power produced during this time is a lot more than the amount of power your home would use in this entire duration. What’s more you can offset your costs by selling the excess amount of power to your local power company.
There are 3 types of solar power systems, as listed below:
This is the most common type and connects the system to the electrical grid and allows the home owners to use both – the grid’s electricity and solar energy. The unique feature of this system is that when the residents do not need power or there is excess of it, the solar panels automatically send the excess electricity produced back to the grid, thereby making it useful somewhere else. On the flip side, in the event that the solar panels are unable to produce enough power for the users (due to cloudy and stormy days, night time), the users get their electric supply from the grid.
As the name suggests, this power system is not connected in any way to the electricity grid. This system uses batteries instead that help balance out any shortfall and excesses in production and demand.
To ensure that the users do not suffer any inconvenience when the solar panels are unable to produce power and the batteries are discharged, there is an electric generator that can be added, as part of the overall system. This generator would serve as the power source during periods of short or irregular power production and or excessive demand on the power produced.
This system combines the grid connection with the energy storage capacity of your home – i.e. instead of sending the excess power back to the grid (as in On-grid systems), you can store the energy for use during power demand peaks or low production due to less or no sunlight. This system is highly sophisticated and gives it users reliable, cost effective and environment friendly electricity at all times.
In the world today energy prices are going north and creating imbalances in the lives of the masses. The great part about solar power is that it gives you a number of choices and provides you with the edge in dealing with the energy and its cost problems.
