Battery vs Net Metering [Which One is Better for Solar Users]?

Battery vs Net Metering is the topic of public interest since the cost of electricity is extremely high in 2025. Anyone thinking about installing a solar system for domestic use at home must face this question “Should I go for batteries or net metering”? Both options have their own benefits. Mostly it depends upon needs, location, and budget.

Let’s break it down in simple words. I will try to provide you with the answer that makes your concept about the batteries and net metering clear.

What is Net Metering?

Net metering allows you to send your extra solar energy back to the MEPCO grid. In return, MEPCO gives you credit for the units you export to its system. These credits reduce your monthly electricity bill. In simple words, you can sell your excess solar converted electricity in the daytime (under sunshine) to MEPCO and at night times you will get it back.

But there is a twist. It is not as simple as it looks in first instance. You will get back the one third of the units you had provided to MEPCO. In simple mathematics, if you had provided or sold 90 units to MEPCO/WAPDA in day time, you would get 30 units back in lieu of those 90 units in the night use.

Here’s how it works:

Your solar panels generate electricity during the day. If you don’t use all of it, the extra power goes to the grid. At night, or during cloudy days, you use power from the grid. Your exported units are adjusted against the imported ones. So, with net metering, your electricity bill can be reduced to zero, or even go negative in some cases.

But remember: this system only works when the grid is available. During load-shedding or grid failure, your solar system shuts off completely.

So, what to do in this case? Here comes the placement of batteries. In this scenario, you have to switch on an off-grid system or a hybrid system or a battery backup.

What is a Solar Battery System?

A battery stores the extra energy your solar panels produce. You can use it at night or during power outages or in cloudy weather.

Here’s what you get with a battery:

·       Backup power during load-shedding.

·       Freedom from the grid.

·       More control over your energy usage.

Modern lithium batteries are long-lasting and smart. They charge during the day and discharge automatically when needed. But the evil lies in these initial costs, as they are extremely costly. You have to spend a huge amount on modern lithium batteries in 2025.

Here is an estimate of the huge cost a good-quality lithium battery in 2025. A good-quality lithium battery like Tesla Powerwall or AGS etc. may cost between PKR 280,000 to PKR 500,000. But it depends upon some factors like size of the battery, the season of purchase, and the dollar rate.

Battery vs Net Metering – Quick Comparison

Feature	Net Metering	Battery System
Reduction in Electricity Bill	Yes	Yes
Works During Load-shedding	No	Yes
Initial Cost	Lower	Higher
Maintenance Cost	Low	Medium
Lifespan	10–15 years	3–5 years

Which One is Better for You [Battery vs Net Metering]?

It mostly depends on your situation. If you want to reduce your electricity bill. You are living in an area that is load-shading free. If you don’t face frequent power cuts, then you have to go for net metering.

But on the other hand, you live in an area with long power outages and want full independence. In this case, you have to go for batteries.

You can also combine both. Many solar users install net metering and keep a small battery for backup. This way, you enjoy the best of both worlds.

Solar energy is a smart investment. Whether you choose batteries or net metering, you’re saving money and protecting the environment. Green energy is the life-saving solution for all of us in 2025 and the time ahead.

Just make sure you:

·       Do a proper site survey.

·       Hire a certified solar installer.

·       Buy Tier-1 solar panels and inverters.

This will help you get the most from your solar system, no matter which option you choose.
