A 3 kW system will cost about $6,300 to install, including the federal solar tax credit, and will pay for itself in just under 11 years..
A 3kW on-grid system on average can range approximately between Rs. 2,13,300 to 3,59,296, depending on the selected components..
On average, the cost for this solar system is around $6,000. This upfront investment will yield significant savings and returns over the system’s lifespan.
