With the fast industrial development, climate change and regional conflicts around the world, the issue of electricity around the world is becoming a new challenge. Solar power energy system is becoming a trend, and it’s a great solution for solving power shortages, high electricity costs and environmental pollution problems, it works simply by absorbing solar energy to convert electricity.
ON-GRID SOLAR POWER SYSTEM
With the rapid advancements of technology in the field of solar energy, more and more people have started installing solar power system. Of the several types of different systems installed across the globe, the on grid solar power system is the most widely chosen one.
What is on-grid solar power system?
On-grid solar power system is a solar power generation system where it is connected to the utility grid. The electricity produced by the system is routed to the grid from where it is used to run the various appliances. The excess power at any point of time is transmitted back to the grid.
The solar power is produced only when the grid is available. The power supply gets completely cut-off in case of the grid outage. Hence, one needs to depend on back-ups such as DG sets for emergency power supply. The power shut down happens, mostly in case of safety and technical reasons.

Benefits of on-grid solar
1. Zero Electricity Bills — Though the solar power system is connected to the grid, the consumer has to pay only for the surplus electricity he consumes. The bill generated on a monthly basis determines whether the consumer has any payments to be made. However, at the same time if the consumer utilizes less electricity, the excess is fed back in the grid.
2. Easy maintenance — The on grid solar power system has the least number of parts along with simple installation. The elimination of batteries makes the maintenance quite easy.
3. Passive income generation — With connection to the grid, the consumer can charge for the surplus electricity he has generated. It not only eliminates your electricity bills but also avail the cost benefits for the excess electricity generated.
4. On-grid solar systems are most cost-effective and convenient to install. These are ideal systems for households as the cost charged can be recovered easily through the additional power transmitted to the grid.
OFF-GRID SOLAR POWER SYSTEM
Installing an off-grid solar inverter has become the main concern for most of the people living in the remote parts of the world. Because it totally lessens our reliance on the grid, thus meeting our power needs completely through solar energy.
What is off-grid solar power system?
Known as a stand-alone power system (SAPS).It works by generating electricity from solar panels and using it to charge a solar battery via a charger controller. That electricity is then converted using an inverter so that it can power the home or business appliances. By saving the electricity in a solar battery, it is possible to run home with solar energy, even at night or during times when there is less sun exposure.
How does off-grid solar power system works?
In an off-grid solar system, your solar panels will generate electricity and any excess energy generated will be used to charge your solar batteries for use at night or times when your system is not generating enough power. It is considered to be a good option compared to an alternative backup power source, such as a generator.
Here the key components are solar charge controller, AC load, solar panels and inverter. One thing to know here is that an off-grid system makes use of just one kind of energy source at a time for running the appliances.
If sufficient solar energy is available, this system would run your load completely on solar. If the solar energy received is less for running the load, it’ll take the remaining of the needed power from the batteries and run the load.
In either of the cases, it won’t run your load via mains. If the solar energy is not sufficient and the battery is discharged to a user settable value just then the inverter runs the load straight via mains and utilises solar power for charging the batteries. This makes sure that grid supply is minimum used which highly reduces your monthly expenses.
Advantages of Off-Grid Solar Systems
1. No access to the utility grid
Off-grid solar systems can be cheaper than extending power lines in certain remote areas.
2. Become energy self-sufficient
Another big advantage of going off grid is that, 100% independence from electricity retailers. Need not to pay anything for electricity costs, and 100% insured against rising energy prices. System also protects from grid-tied power failures or blackouts. Living off the grid and being self-sufficient feels good. Energy self-sufficiency is also a form of security. Power failures on the utility grid do not affect off-grid solar systems.
Hybrid SOLAR POWER SYSTEM
What is Hybrid solar power system?
Hybrid solar systems have both on-grid and off-grid capabilities. In translation, a hybrid solar system that is grid-tied and includes battery storage. The system holds a hybrid inverter that can switch between using solar power, battery power, and grid power intelligently, Solar panels utilize sunlight to produce electricity, while the batteries store energy for backup during power shortages. As a result, hybrid solar systems can provide continuous power even if the grid goes down or in the absence of sunlight.

Just like any solar panel system, this system lets you
Advantages of Off-Grid Solar Systems
· Can Save money on your electricity bills by using solar power during peak hours and avoiding grid power at high prices.
· With a hybrid solar system, you have additional backup power in case of a grid outage or blackout.
· It reduces your carbon footprint and environmental impact by using clean and renewable energy.
· Hybrid solar systems can increase energy independence and self-reliance by having more control over the power supply.
