Off grid versus grid tied solar panels are used extensively in rural areas where access to the grid is non existent or inaccessible.
On grid solar energy system.
Whenever the sun shines and even in overcast weather the solar cells generate electricity.
For an off grid solar system you need four basic components.
Only you have to know some basic electrical and math for designing the entire system.
Solar panel pv panel 2 charge controller.
Unlike grid tied solar systems off grid systems have no connection to the utility grid and must make all the electricity necessary to power your home.
The grid connect inverter converts the dc electricity produced by the solar panels into 240v ac electricity which can then be used by the property household.
An off grid solar system is designed for the power needs of mid to large size homes.
These installations are called off grid or independent stand alone solar power systems and require the use of batteries to store the energy for use at night or on long stretches of overcast weather.
Off grid solar homes almost always will use batteries to store their excess electricity.
Instead of this i have attached links of my other instructables to make the charge controller and energy meter.
Off grid solar systems operate from the stored energy in a battery bank.
If a grid connect system is producing more.
Made with high efficiency solar cells with high module conversion efficiency and long term output reliability this solar kit is easy.
