4 Acre Solar Farms in India
A 4-acre solar farm is a large-scale renewable energy project that utilizes photovoltaic (PV) solar panels to generate electricity from sunlight.
It’s ideal for industries, investors, and commercial institutions seeking a sustainable and profitable way to produce clean power.
Depending on the configuration, a 4-acre system can produce 850–900 kW of solar power, contributing significantly to India’s green energy transition.
Challenges of Building Private On-Grid Solar Farms in India
While setting up your own 4-acre on-grid solar farm sounds profitable, it is not always practical.
The primary challenge lies in grid connectivity — the nearest substation is often several kilometers away, leading to high cabling expenses and complex regulatory approvals.
Common challenges include:
- Long-distance cable connection cost: ₹40–₹60 lakhs additional expense.
- CEIG and DISCOM approval delays due to regulatory compliance.
- Limited capacity: 4-acre farms typically allow only 880–900 kW capacity.
- Fixed infrastructure costs that make small standalone projects less viable.
Hence, most investors find it smarter to invest in shared PPA-based solar projects rather than building independent on-grid systems from remote locations.
Join Synergy Solar’s PPA-Powered Solar Investment Program
That’s why Synergy Solar Solutions offers a practical way to earn from solar — through PPA-based solar investment programs using our ready, grid-connected solar zones.
You can:
- Buy or lease a 4-acre block in our pre-approved solar park
- Earn consistent income from electricity sales
- Avoid dealing with government approvals, CEIG testing, or land management
With this model, you gain annual returns of ₹25–₹35 lakhs, backed by long-term Power Purchase Agreements and complete EPC + O&M handled by our team.
This is the most reliable solar income model for businesses, NRIs, and investors seeking predictable ROI.
4 Acre Off-Grid Solar Power System for Independent Energy Use
If your goal is energy independence rather than direct income, installing an off-grid or hybrid solar system on your 4-acre land is a powerful solution.
A 4-acre solar setup (~880 kW) can efficiently power:
- Industrial plants, rice or flour mills
- Cold storage, warehouse, or dairy units
- Farmhouses, pumps, or commercial complexes
While this system doesn’t export electricity, it reduces EB and diesel costs by ₹18–₹22 lakhs/year, helping you operate independently of grid fluctuations while maintaining stable, clean power throughout the year.
