1. Cost Influencing Factors of Solar Installation in India

A solar system does not cost the same; it is a variable that is based on various technical and structural aspects. Knowledge of these assists you in approximating the appropriate budget.

A. Type of Solar System

• On-Grid: The cheapest type; appropriate in homes that have a smaller frequency of power outages.
• Off-Grid: Batteries are also included; more expensive as there is a necessity to have a backup.
• Combination of both; high quality and most all-purpose.

B. System Capacity (kW Rating)

• Increased capacity means increased cost, but increased savings and quicker ROI.

C. Solar Panel Type

• Premium, High Efficiency (Mono PERC)
• Polycrystalline (Budget-friendly)
• Bifacial (Enhanced Generation)

D. Inverter Technology

• String inverters (cost-effective)
• Microinverters (high quality, single panel efficiency)

E. Installation Structure Requirements

• Flat RCC roof
• Tin shed
• Elevated structure
• Special angle or special design

F. Location & Labour Cost

• Installation cost is subject to change depending on the city, material logistics and manpower.
