What does mean by Off-Grid Solar Power System?
Off-Grid Solar System is a type
of solar power system run by generating electricity from solar panels and using
it to charge a solar battery through a charging controller. That electricity is
then adapted using an inverter, which helps to power the home appliances or
business’ equipment. The off-grid solar system is not connected in any way to
your grid’s power system, hence, providing 100% self-sustaining energy for your
usage.
Off-grid solar power systems
(entirely self-sustaining) allow you to store and save your solar power or
natural energy in batteries for future use, especially when the power grid goes
down. The foremost advantage of using the off-grid solar system for home is to
run household applications with solar energy during night or anytime when there
is less sun exposure and only by saving the electricity in a solar battery.
The solar power system is also
known as a stand-alone power system and acknowledged in the market due to
several reasons like cheapest price than extending power lines in certain
remote areas, 100% independence from electricity retailers, and 100% insured
against rising energy prices.
On the other hand, the off-grid
solar system for home uses as an appropriate alternative in the remote areas
where the grid is unavailable for power supply. SolarClue is an online platform
where people can buy a solar power system (Off-grid) on different brands like
Supreme, V-Guard, Varistor Solar, and Luminous. The solar system price is
varied from one brand to another available with SolarClue.
Components of an Off-Grid Solar Power System
Total of five components used in
off-grid solar power system, which are as follows:
Solar Panel – It is one of the
important elements of the off-grid solar power system. The solar panel operates
based on by depending on the amount of available sunlight in the region, the
usable space of roof, and energy consumption needs.
Solar Battery – It is another
component of the off-grid solar system and useful to allow the home to continue
to run after the sun goes down. Solar battery or solar storage device is
responsible for charging the home appliances throughout the day as solar panels
generate excess electricity. This is capable of storing solar power for later
use of running the household appliances.
Solar Inverter - Solar power
system prerequisites a solar inverter to convert the direct current (DC)
collected by the solar panel into the alternating current (AC) that enables to
run the household appliances and electronics. A stand-alone inverter is an
ideal option for off-grid system use. Solar inverters are referred to as a
solar converter or a PV inverter.
Solar Charge Controller - The
solar charge controller is necessary to save battery backup for operating the
different household electronic products. The controller is used in regulating
the voltage that solar battery receives, to prevent overcharging, and any
damage.
Off-Grid Generator System - It is
considered an alternative source of energy as a backup of the system. This is
the main requirement during the pick winters when solar production is at its
lowest. Off-grid generator systems are also useful to power a home’s
electricity needs.

Application Areas of Off-grid Solar Power Systems
• Rural and remote areas - Off-grid solar system offers electricity supply in rural and remote areas with the facilities of long-term and sustainable power generation.
• In areas with frequent electricity cuts – Off-grid system provides power back up facilities to those areas, which are facing frequent power cuts due to power transmission malfunctions.
Solar Components are important for every home solar electric system to help in producing electricity and converting it into the alternating current; thereby using in home appliances, storing excess electricity, and maintain safety.
Solar components are classified into seven categories such as Solar Pumps, Solar Charge Controllers, Solar Combiners, Solar Mounting Structure, Solar Tools, Solar Cables, and Solar Surge Protection Devices. These all are functioned using solar energy (sunlight), which turns into electricity. The entire solar components are manufactured and stringently inspected as per International Quality and Safety Standard.
Solar Pump
The solar pump is a solar water pumping system operated using solar energy to pump clean water. The solar pump is ideal, especially for rural localities (beyond the reach of power lines), where people are unable to avail of electric consumption by using the local electricity grid.
Solar pump or solar-powered water pump is in demand due to its robust construction, easy installation, eco-friendliness, and minimum maintenance. Solar pumping is the best alternative for fuel-burning generators and windmills, in which the electricity is provided by one or several Photovoltaic (PV) panels to offer water even if using without electricity. The water supplied by the solar pump is used to irrigate crops, provide clean drinking water, and also offer water for livestock. Apart from these, some other application areas for which solar water pumping system is used including fountains, pools, ponds, and home pumps.
A solar water pumping system consists of a solar panel that provides power to an electric motor, which in turn is capable of powering a bore or surface pump. Hence, the water is pumped from the ground into a storage tank that provides a gravity feed, and for this reason, energy storage does not require for the solar pumping system. The life span of a solar pump or solar water pumping system is a maximum of 20 years, but a solar panel of the pumping system needs cleaning from time to time to run properly. People can purchase it as per their requirements because the solar pump price is varied from its manufacturing capacity, sizes, patterns, and different brands.
Benefits of using solar pump

Solar Charge Controller
The solar charge controller is a device, which maintains the proper charging voltage in batteries of any solar appliances. All solar electric systems with batteries should have solar charge controllers. The solar charge controller regulates the voltage, prevents overcharging and allows batteries to charge when required, because batteries can be overcharged if it feeds continuous voltage.
The main function of solar charge controller is to prevent overcharging of the batteries and regulates the amount of current the PV modules feed into a battery bank. However, charge controller can block battery bank current from leaking back into the photovoltaic array during night or cloudy times for saving to drain the battery bank.
Most home solar systems are built with a battery backup controlled using solar charge controller, which ensures that a consistent amount of electrical power is sent to the and the backup batteries of any solar system do not discharge during night or absence of sunlight. Solar charge controller price is very minimal so that anyone can buy it as per their necessities.
Solar charge controller or solar battery charger comes with two types of sizes and technologies such as MPPT (Maximum Power Point Tracking) and PWM (Pulse Width Modulation) that are capable of functioning an off-grid power bank system properly. Charge controller is used within an off-grid or hybrid solar system with appropriate battery back-up.
Benefits of solar charge controller
• Works to control voltage and watts from Solar Panels
• Reduces the voltage of solar panels when a solar battery’s voltage is high
• Helps to maintain stable energy by preventing overcharging and protecting against overvoltage
• Stops reverse current during night or when sunlight is not available
Solar Combiner
The solar combiner or solar combiner box is a device operated using solar energy (sunlight) that combines the output of multiple strings of PV modules for connection to the inverter. Solar combiner is developed in such a way to bring the output of several solar strings together. Usually, each string conductor lands on a fuse terminal and the productivity of the fused inputs are then joined onto a single conductor that connects the combiner box to the inverter.
Solar combiner box also combines incoming power into one main feed, which distributes to a solar inverter that is capable of saving labor and material costs through wire reductions. Solar combiner is engineered even to provide overvoltage as well as overcurrent protection facilities to enhance inverter protection and reliability.
The solar combiner generally exist in between the solar modules and inverter, which is the correct position. Solar combiner can limit power loss when it is positioned in the solar system. Solar panel combiner box and solar string combiner box are two different types of solar combiner. Moreover, solar combiner is usually used in the larger commercial and utility scale PV power plants (greater than 500kW).
Benefits of using solar combiner
