Transitioning to solar energy is one of the most effective steps toward energy independence, especially in rural areas where grid reliability remains a challenge. Our technical team recently completed a detailed site survey at Pabal, Maharashtra, for our customer, Mr. Shivaji Shanker Bakate. Here is an inside look at how we evaluated the site conditions, calculated energy demands, and designed a reliable solar system.

1. Comprehensive Site Evaluation

A site visit allows engineers to inspect real-world physical and environmental conditions before installation. The technical key points from our assessment include:

  • Geographic Coordinates: 18^\circ 50′ 52.4”\text{N}, 74^\circ 03′ 04.5”\text{E}
  • Roof Characteristics: A metal shed home featuring a sloped roof with an optimal tilt angle of 18.83^\circ.
  • Sunlight Exposure: Unobstructed sun exposure with zero shadow from 9:00 AM to 5:00 PM, ensuring maximum panel performance throughout the day.
  • Site Conditions: 6-meter house height, max wind speed of 10–15 km/h, and a 50-foot distance to the MSCB grid pole.
  • Electrical Safety: Existing earthing was missing, requiring fresh copper-bonded earthing kits for plant protection.

2. Load Assessment & Rural Energy Demands

Understanding customer load is vital for system reliability. In rural settings like Pabal, grid outages occur daily for 3 to 4 hours. Additionally, the system must handle both regular household usage and heavy agricultural appliances.

Daily Appliance Breakdown:

  • Domestic Load: 4 fans (55W), 12 LED bulbs (10W), 1 TV (255W), 1 refrigerator (250W), mixer (500W), room heater, and additional appliances total an estimated daily load of ~8.89 kWh (units).
  • Heavy Utility Demands: The client specifically requested power support for heavy appliances, including a 2 HP motor, a milking machine, and a chaff cutting machine.

3. The Proposed Solar Solution

Because grid outages coincide with peak working hours, a standard on-grid system would leave the customer stranded during power cuts. Therefore, we designed a Hybrid Solar System that combines grid connectivity with battery back-up capability.

Conclusion

By matching high-efficiency Adani TOPCon panels with a hybrid inverter, this solution ensures Mr. Bakate can operate domestic lights and heavy agricultural equipment without disruption. Within a budget of ₹2,50,000, this setup provides a sustainable, long-term fix for rural power reliability.
