Why Granite Exporters Should Consider Solar
The granite industry faces significant energy challenges that directly impact our bottom line. Let's examine why solar energy offers a compelling solution for our sector.
Rising electricity costs in the granite industry
Granite processing units consume substantial electrical power, making energy one of our largest operational expenses. Studies show the stone industry is historically a high electricity-consuming sector. The manufacturing industry alone consumes over 47% of national energy in countries like Germany. For granite exporters, monthly electricity bills often reach tens of thousands of rupees, with costs steadily climbing year after year.
Challenges with grid reliability and diesel usage
Many granite units operate in non-urban areas where consistent power supply remains problematic. This unreliability stems from aging infrastructure, unexpected weather events, and even cyber threats to power grids. Consequently, most operations rely heavily on diesel generators as backup.
Diesel dependency creates another set of challenges. The average granite factory consumes between 1.07 to 3.57 liters of diesel per ton of product, with diesel combustion accounting for 68% of direct greenhouse gas emissions. Furthermore, diesel prices fluctuate with global markets, making cost projections difficult.
How solar offers a long-term solution
Solar power presents a fixed-cost alternative that shields granite exporters from rising energy costs. Solar tariffs are typically 20% cheaper than conventional electricity rates, providing immediate savings. Moreover, the economics improve over time as traditional electricity prices continue to rise while solar costs remain constant.
The real-world benefits are compelling. Anjalee Granites, a pioneering granite exporter, installed a 1.6 MW rooftop solar system that saved approximately Rs. 1.4 crore ($150,000) with a payback period of just 3 years and 9 months. Similarly, other stone processing units report recovery of their solar investment within 3-5 years, followed by two decades of substantially reduced energy costs.
Beyond economics, solar adoption also addresses grid reliability issues by providing consistent power during daylight hours when production is typically highest. This independence from grid fluctuations ensures smoother operations and fewer production interruptions.
Understanding the Financial Benefits
The numbers tell a compelling story when it comes to solar energy for granite exporters. Let's examine why the financial benefits make solar an intelligent business decision.
How solar energy reduces monthly electricity bills
Solar installations can significantly reduce or even eliminate monthly electricity expenses for granite units. Once installed, a solar power system provides consistent energy with minimal ongoing costs. For stone processing units like ours, which consume substantial power, this translates to immediate relief from high electricity bills. With net metering available in many states, excess power generated during peak sunlight hours can be sent back to the grid, earning credits that further offset costs. Ultimately, these savings directly improve our bottom line.
Fixed-cost advantage vs. fluctuating tariffs
Perhaps the most significant benefit is protection from rising energy costs. Traditional electricity rates have increased by approximately 4.5% annually over the past two decades. In contrast, solar energy offers price stability with fixed, predictable costs after installation. This shields our operations from market volatility and allows for more accurate long-term financial planning. In fact, granite processors with solar installations report consistent energy expenses regardless of market fluctuations.
Government subsidies and tax incentives
The government offers substantial financial support for solar adoption, including:
- Accelerated depreciation of 40% in the first year, significantly reducing tax liability
- Capital subsidies that offset initial investment costs
- GST reductions on solar components
- Tax credits and deductions for solar installations
Solar energy cost savings vs. traditional energy
In practical terms, solar systems typically pay for themselves within 3-5 years for granite units. After this brief payback period, businesses enjoy essentially free electricity for the remaining 20+ years of the system's lifespan. This represents enormous savings compared to traditional power, where commercial establishments face tariffs of ₹8-12 per unit with rates continuing to rise.

Real-World Examples of Solar Savings
Case study: 500kW solar plant for a granite unit
A pioneering granite exporter, commissioned a 1.6 MW rooftop solar system that demonstrates the potential for our industry. This installation now saves approximately Rs. 1.4 crore annually. Meanwhile, a typical 500kW system requires around 1500-1600 solar panels and can generate approximately 690 MWh of electricity per year.
Monthly and annual savings breakdown
For stone processors, the savings are substantial. A 530kW installation delivers monthly savings of Rs. 5,85,000 with electricity priced at Rs. 9 per unit. Generally, industrial units see payback periods between 3-5 years, after which they enjoy essentially free electricity for the remaining 20+ years of the system's lifespan.
Comparison of solar vs. grid electricity costs
Traditional power in India relies heavily on coal, with commercial electricity rates between Rs. 8-12 per unit. In contrast, a solar installation offers significant protection against these rising costs. The performance ratio for a typical 500kW system reaches about 80-83% efficiency, meaning minimal losses in the network.
Commercial solar energy savings in Tamil Nadu
Specifically in Tamil Nadu, businesses are increasingly adopting solar to address energy challenges. Commercial installations can slash monthly electricity bills by up to 80%. A manufacturing unit consuming 100,000 units monthly at Rs. 7 per unit can save approximately Rs. 84,000 monthly by installing a 100kW system—translating to Rs. 10.08 lakhs annually.
