When you get a solar system in Kolkata, your savings will depend on system size, factory size, angle of roof, duration of daily sunlight, and how much you use electricity. At Bhoodarsh Saurshakti, we get a lot of clients who say: Is it worth it? Let’s break down the idea of savings and show you not only the bottom line but also how RMPPT Solar PCU Installation Services can enhance your savings even further and increase your savings.
Understanding the Baseline Costs in Kolkata
- At this time, a complete solar system (panels + inverter + mounting + balance of system) that is a 1 kW system in the Kolkata general area will be around ₹ 80,000 (this number will include the panels, wiring, installation, etc.)
- Just for clarification, the panels alone would be about ₹ 30,000 for 1 kW of panels – as you can see, the other costs (Inverter, structure, cable & labour) make up the additional cost.
- For example, if a person wants a 2kW system, a two kW system might be in the range of ₹ 1,40,000–₹ 1,80,000 in West Bengal.
The above expenses are your initial investment. Now, what are the savings in ongoing electricity bills?
Estimating Savings on Electricity Bills
In Kolkata, average residential electricity tariffs are in the ₹ 6–8 per unit range (which varies per slab and per distributor). Let’s say you install a 3 kW system, and, on average, it generates 12 units per day (again, it varies based on hours of sunlight). Estimating (every month):
| Metric | Estimate | Monthly Value |
| Daily Generation ( 3 kW system) | 12 unit | 360 units/month |
| Value per unit | ₹ 7 | – |
| Monthly Offset of Electric Bill | 360 × 7 | ₹ 2,520 |
| Annual Offset | ×12 | ₹ 30,240 |
Therefore, a 3 kW system can offset ≈ ₹ 30,000 in electric bills every year. This means over 20 years of savings would be approximately ₹ 6,00,000 (before maintenance, servicing and inflation).
Again, these are rough estimates. Actual savings are determined by system quality, shadowing, usage patterns and the grid connection.
Role of RMPPT Solar PCU Installation Services
Unit efficiency and installation are important for optimal energy return. Here’s how RMPPT Solar PCU Installation Services increase optimum energy production:
- RMPPT (Rapid Maximum Power Point Tracking) guarantees that your inverter consistently operates at your panels’ maximum power point, even in conditions of partial shaded or limited panel exposure.
- The quality of the PCU (Power Conditioning Unit) ensures that the DC from your solar excursion is converted and conditioned to AC with the least amount of losses possible.
- Quality installation (solar panel orientation, tilt, and adequate space to limit shading) ensures that the system produces maximum yield throughout the entire day.
- The monitoring and maintenance program allows for early identification of decreased system performance or faults.
RMPPT PCU technology, along with quality design and high-grade components, will increase your system’s effective output even further, thereby increasing your savings.
Factors That Affect Your Actual Savings
- Roof Orientation & Tilt – systems are most efficient when facing south or when inversely tilted or unobstructed.
- Shading from adjacent buildings, trees, horizontal objects, and the time of year will affect optimum energy production.
- System losses will occur (interconnect wiring, inverter losses, dust accumulation on panels, and any maintenance downtime, which will affect the energy production of the system.
- Tariff structure – is your electricity provider’s cost structure slab rates that are excessive, or high demand charges?
- Subsidies or rebates – may be available in your area (West Bengal) that can reduce your net cost for solar.
Final Thoughts & Recommendations
Solar systems are not just luxury items anymore – when you decide on the right system, you can earn back the solar panel price in Kolkata within 6-8 years (7-9 years fast with RMPPT) and then enjoy many years of seriously cheap electricity.
