100 kW Solar Plant Cost in Rajasthan: Latest Cost, Maintenance & Payback Time
For commercial establishments, educational campuses, hospitals, and large rooftop spaces in Rajasthan, installing a 100 kW solar power plant is a powerful step toward reducing energy costs and embracing renewable energy. At Smart Roof Solar, we deliver turnkey systems that optimize your solar energy installation cost, drive down solar installation charges, and tap into the government solar subsidy scheme where applicable.
This blog covers the pricing, generation, benefits, subsidy conditions, and other key considerations for a 100 kW system in Rajasthan, with clear data and keyword-rich content to help you plan smart.
What is a 100 kW Solar Power Plant?
A 100 kW solar power plant means a system capable of producing 100 kilowatts of peak power under standard test conditions. In Rajasthan’s favorable solar climate, this often translates to 1.4 to 1.6 lakh units (kWh) of electricity annually, depending on site conditions.
This scale is ideal for mid- to large-sized facilities looking to significantly reduce their electricity bills, advance their sustainability credentials, and benefit from renewable solar and renewable energy technology.
100 kW Solar Power Plant Price in Rajasthan (2025)
Next, let’s look at the total cost of solar installation, typical cost components, and how you should evaluate the investment. Here’s a table you can fill with your specific rates from Smart Roof Solar:
Capacity  | Estimated Cost (excluding GST)  | 
50 kW in Rajasthan  | Starting from ₹12,50,000*  | 
100 kW in Rajasthan  | Starting from ₹24,00,000*  | 
150 kW in Rajasthan  | Starting from ₹35,25,000*  | 
200 kW in Rajasthan  | Starting from ₹47,00,000*  | 
*Prices quoted are indicative starting rates for 100 kW solar installations and may vary based on project-specific requirements, including ground mount or tin-shed structures, RC installation types, additional accessories like DG sync, safety rails, etc. Final pricing will be confirmed upon detailed site evaluation and project scope assessment
As a rule of thumb for 2025, the average cost of solar panels on a house or commercial rooftop in Rajasthan lies around ₹38,000-₹50,000 per kW, depending on quality, mounting type, and site conditions. The larger the system, the better the scale benefit on the cost of solar panels and the overall solar panel system cost.
Power Generation & Payback
With Rajasthan’s high irradiation, a well-configured 100 kW system on a good roof could generate approximately 1.4-1.6 lakh units a year of solar electricity. If your commercial tariff is about ₹8-₹10 per kWh, your annual savings could be ₹11-₹16 Lakh.
This means you could recover your entire investment in around 3 to 4 years, depending on your actual cost and generation. After that, the electricity you get is almost free, significantly lowering the cost of solar per kWh installed for the lifetime of the system (typically 25+ years).
By focusing on making solar energy economical, you convert your rooftop or land into an asset that delivers for decades.
Ideal Applications for a 100 kW Solar System in Rajasthan
This system size is well-suited for:
- Manufacturing or industrial units in Rajasthan’s industrial corridors
 
- Commercial complexes, hotels, schools, and hospitals with large roofs
 
- Cold storage facilities, warehouses, and large agricultural operations
 
- Campuses, educational institutions seeking energy self-reliance
 
Whether you’re evaluating your solar roof installation cost or comparing solar installation cost per kWh, a 100 kW scale (with high-quality design and monitoring) offers strong value and long-term returns.
Cost & Savings Influencers
When planning your 100 kW system, consider these factors:
- Module efficiency and smart solar panel price: Higher efficiency = smaller area ≈ lower mounting cost.
 
- Roof condition, height, and orientation: These influence labor, solar installation charges, and shading losses.
 
- Quality of installation & maintenance (O&M): Poor installation increases your total cost of solar installation and reduces generation.
 
- Cable length, earthing, and monitoring: Proper design keeps the cost of solar per kWh installed lower.
 
- Tariff escalation and net-metering rules: Higher future grid tariffs improve your savings.
