Solar Technology Details You Should Know to Succeed in the Solar Business in 2025

The current solar market in India is experiencing record growth because the government is popularizing solar on a mass scale by offering homeowners and housing societies a subsidy under the PM Surya Ghar Muft Bijli Yojana to install on-grid rooftop solar systems.  

As someone planning to start a solar business, you should be aware of the following details:

• Subsidy is offered only for residential purposes: There’s no subsidy provided for installing off-grid solar systems that are connected to a lithium battery bank instead of the utility grid, ground-mounted solar systems, or on-grid rooftop solar systems for commercial purposes. Only homeowners and housing societies that install on-grid rooftop solar systems for residential purposes are eligible for a subsidy if they choose made-in-India DCR modules.
• Polycrystalline solar panels are almost obsolete in India now: High-efficiency solar panels such as bifacial solar panels with mono-PERC half-cut solar cells have left older technologies behind. These panels are current favorites in the residential and commercial markets because they achieve efficiencies as high as 22.5%. Some future technologies to watch out for include TOPCon solar panels, perovskite solar cells, and multi-junction solar cells.
• MPPT solar inverters offer the best performance under partial shading: The MPPT algorithm has taken the solar world by storm. It ensures solar panels generate maximum possible output at any given point during the day. Such technologies have significantly improved the reliability of solar output in cases of partial shading.

What’s the Current Solar Panel Installation Cost in India?

Installing on-grid rooftop solar systems at homes in India in 2025 can cost homeowners somewhere between ~Rs. 90,000* in Lucknow for a 2 kW solar system and ~Rs. 5.62 lakh* in Bengaluru for a 10 kW solar system after they avail of a subsidy under the PM Surya Ghar Muft Bijli Yojana.
