To create an offgrid solar power system, you will need 4 main items which are: solar pv modules, charge controllers, batteries, and inverters. You will need a mount to place the modules on to fix the solar panel
s to the roof or a ground mounted pole. If the system is ground mounted, many people choose to install a sun tracker to maximize the efficiency of the panels.
Lets examine each in detail:
Solar module - A module is a collection of solar cells tied in series otherwise known as a solar panel. Each solar pv panel is enclosed by plexiglass or some other transparent material that allows sunlight to shine through and create an electric current. The solar cells in the solar module determine the efficiency of the pv power system. Depending on the rating of the solar cells, a system can convert anywhere from 12- 25% of sunlight into usable electricity.
Charge Controller - This device prevents the battery from being overcharged and eliminates any reverse current flow from the batteries back to the solar module at night or cloudy days. Charge controllers are connected directly to the module and takes current from the module to a battery.
Battery - This is the storage device which stores electricity produced by the module so that it can be used any time of the day. Batteries come in many different sizes the main one being a 12V battery. Several of these are connected to create a battery bank.
Inverter - An inverter converts the direct current created by the module into alternating current (AC) which can be used by most appliances. Inverters are connected to the battery and then out to appliances or lighting in your home.
In today's world, have risen to an unexpected level of solar panel cost. It has gained a lot of popularity and has come up with different kinds of variations in its content.
