Proper Way of Installing Solar Panels in Your Place – A Step-by-Step Guide
June 26, 2021• No fossil burning or green houses gasses—thus, ensuring more breathable and cleaner environments.
• The energy is free—you don’t have to bother different production houses for any sort of power requirements.
• They are more reliable source of energy in remote areas where electrical production is not automated.
Now the question rises, as there are two sorts of solar panel system—grid or off-grid, which one is right for you? Here, we will discuss the differences between an on-grid & off-grid solar system, so that you can decide on your own.
On-Grid Solar Panel System
Working
The on-grid PV systems convert the sunlight into DC energy—as the dc power cannot be consumed by the standard home appliances, thus a solar inverter is used to convert the DC power into alternating current, then this generated energy is consumed by the appliances. The energy that is not consumed in the place, it is fed to the grid and in return the user gets credit or get paid to a feed-in-tariff. In on-grid solar panel systems, typically no batteries are used.Pros of On-Grid Solar Panel Systems
• You get paid for energy you export.• The credits for energy can be used when your solar panel system is not generating energy (rainy days, at night time).
• No expense for batteries is needed.
• These can also export energy to the batteries.
Cons of On-Grid Solar Panel Systems
• In the times of blackout, there is no power generation or available energy to operate the appliance thru solar panel system.• At the night time or when there is no sunlight, they are not able to produce power, or generate credits, thus no help at that time.
• If the grid has received any sort of malfunctioning, and the solar power system is feeding it, then it can be harmful to the people living in the place.
Off-Grid Solar Panel System
Working
The solar panels take in the sunlight and covert it into the DC power. Here, the solar inverters play a keen role in the working of off grid solar panel systems. The energy is stored in the batteries, but as the appliances cannot consume DC energy from the batteries, they are needed to be converted into DC power. The solar inverters as:• Sofar Single Phase Dual MPPT Solar Inverter (5KTLM-G2)
• Sunbridge 2000 Solar Inverter
• Sofar Three Phase 10 MPPT Solar Inverter (110KTL)
They are responsible for converting the DC to AC so that the standard appliance operates without any hassle.
Pros of Off-Grid Solar Panel System
• The energy production on off-grid solar panel system allows you to sustain self-sufficient power system that don’t require any outside power integration.• The cost of installation and energy production of off-grid solar power systems, according to the electrical bills that you might be receiving for whole a year are mostly promising. They put less burden on the pocket!
• As when need to expand the power production, these are much reliable.
• They are not connected to the grid, thus, no possibility of damage from malfunctioning grid.
• They provide electrical power at the times of blackout, night or raining days, when there is no energy production.
Note: The off-grid solar inverters at Maxpower comes with working warranty of up to 18 months thus ensuring quality and durability.
Cons of Off-Grid Solar Panel System
• As compared to typical on-grid solar system price in, they can be costly because of back-up batteries.• The maintenance is much often required than the on-grid solar panel systems.
• They aren’t able to give credits, as no FiT (feed-in-tariff) is featured.
• If the PV system (solar inverter or other component) faces stoppage due to any reason/malfunctioning, then it will shut down the whole place.

Whether on-grid or off-grid, solar systems work on the same basic idea: they turn sunlight into DC power, which is then converted into AC power for your home or stored in batteries.
Using solar panels has many benefits:
-
No burning of fossil fuels or greenhouse gases – cleaner air
-
Free energy from the sun – lower electricity bills
-
Reliable power in remote areas where the grid is weak or unavailable
On-Grid Solar System
An on-grid solar system is connected to the main electricity grid.
How It Works:
-
Solar panels produce DC power.
-
A solar inverter converts it to AC power for your appliances.
-
Extra power is sent to the grid, and you get credits or payment (feed-in tariff) via net metering.
-
Usually, no batteries are used.
Pros:
-
You earn credits for extra energy you export.
-
No need for expensive batteries.
-
Can also export power to batteries if needed.
Cons:
-
No power during blackouts (for safety reasons).
-
Doesn’t produce power at night or on cloudy days.
-
If the grid fails, the system may shut down to protect workers.

Off-Grid Solar System
An off-grid solar system is not connected to the grid. It’s fully independent.
How It Works:
-
Solar panels generate DC power.
-
Power is stored in batteries.
-
A solar inverter converts stored DC power to AC for appliances.
-
High-performance inverter series used across Pakistan include models like:
-
Maxpower Suntronic PV Series (Dual MPPT)
-
Voltas HYD Series (IP66 Weatherproof Hybrid / Off-Grid)
-
PV Tech Series
-
Pros:
-
Fully self-sufficient – no need for grid power.
-
Provides power during load-shedding, at night, and on rainy days.
-
No risk from grid malfunctions.
-
Easier to expand if you need more power.
Cons:
-
Usually more expensive due to batteries.
-
Requires more maintenance than on-grid systems.
-
No feed-in tariff credits.
-
If the inverter or another part fails, the whole system can stop.

Summary: On-Grid vs Off-Grid in Pakistan
-
On-Grid: Sends extra power to the grid, earns credits, no batteries, but no backup during blackouts.
-
Off-Grid: Stores extra power in batteries, works during outages, more cost upfront, but fully independent.
In Pakistan, where load-shedding and high electricity bills are common, choosing between on-grid and off-grid depends on your budget, location, and need for backup power. Many homeowners also opt for Hybrid Systems—combining grid connection, net metering, and battery storage into a single setup. Explore options on Maxpower.
Frequently Asked Questions
What is the main operational difference between On-Grid and Off-Grid solar systems?
On-Grid systems are tied to the utility grid to export excess energy via net metering but shut down during blackouts. Off-Grid systems operate completely independently of the utility grid, relying on battery storage to keep power running during outages.
Can I export excess power to the grid with an Off-Grid solar system?
No. Off-Grid systems are physically disconnected from the utility grid, meaning excess solar generation can only be stored in connected battery banks or dumped, rather than exported for bill credits.
Which system type is best for regions in Pakistan with heavy daily load-shedding?
Off-grid or Hybrid systems are recommended for areas with frequent power outages, as they utilize lithium or lead-acid battery banks to deliver uninterrupted electricity when the main grid fails.
Why do On-Grid inverters automatically shut down during a power outage?
On-Grid inverters feature mandatory “anti-islanding” safety protocols. They instantly shut down during grid failure to prevent feeding high-voltage electricity back into power lines, protecting line workers repairing the grid.
Is it possible to upgrade an On-Grid solar system into a Hybrid setup later?
Yes. By adding a compatible hybrid inverter (such as the Maxpower Suntronic or Voltas series) and a lithium-ion battery bank, an existing on-grid rooftop solar system can be converted to provide battery backup during blackouts.
