If you’ve been planning to install solar power in Kerala, you should know about big news. The Kerala State Electricity Regulatory Commission (KSERC) has proposed new solar energy rules that will take effect from October 1, 2025.
These updates could change the way many households and businesses approach solar. Whether you’re a homeowner who wants to lower your electricity bill or a company searching for solar investment, here’s what the new regulations mean for you and how a reliable solar company in Kerala such as Moopens Solar can guide you through the updates.
What’s Changing?
The KSERC 2025rules are aimed at making Kerala’s energy network more intelligent, more balanced, and future-proof. But they also introduce some changes that all solar consumers need to know.
Net Metering Is Now Limited
One of the biggest changes is a new cap on net metering. From October 2025, residential customers can only install up to 3 kW of solar capacity under the net metering model. If you want to go beyond 3 kW up to 5 kW you’ll need to include a battery storage system that can handle at least 30% of your total solar capacity.
For instance, if you design a 5 kW system, you must have at least a 1.5 kW battery bank.
For most homes, this may be an additional expense. But there’s a silver lining batteries provide you with backup during power cuts and enable you to use electricity more efficiently. And with declining battery costs, hybrid solar systems are gaining traction.
Additional Metering Options
KSERC has also brought in additional metering options apart from net metering. These are:
Gross metering – where you sell all the solar power back to the grid
Net billing– where export and import are billed separately
Virtual and Group Net Metering – perfect for apartments, schools, or farms
If you reside in a flat or run a commercial building, these new possibilities unlock shared solar installation , something that was not easy under old rules.
Time-of-Day Tariffs Are Coming
Another key shift is the addition of Time-of-Day (TOD) tariffs. In this, the worth of solar energy that’s sent to the grid will change based on the time of day. Hence exporting in the daytime could be less lucrative than at top evening hours.
This implies when you produce and use power will become more significant and intelligent planning will be the differentiator. That’s where solar power experts in Kerala like Moopens step in. We can assist you in planning a system to maximize your solar investment.
What About Existing Customers?
If you’ve already got a solar in place and approved under existing regulations, you’re good to go your net metering contract will remain unchanged. But if you’re doing a new installation after October 1, 2025, you’ll need to adopt the new guidelines.
