Let’s break it down in simple, real-world terms so you can make an informed decision.
What Affects the Cost of Solar Panel Installation?
Several key factors influence the final cost:

- Inverter Quality: Hybrid, string, or micro-inverters come with different price points.
- Mounting Structure: Rooftop, ground-mounted, or elevated structures have varying costs.
- Battery Backup (optional): Including batteries adds to the upfront cost but ensures power even during outages.
- Subsidy Eligibility: State and central government subsidies can significantly reduce your cost.
