About
A first visit can provide an initial assessment of the system's potential fit for the property's energy consumption profile. Customers in the Kolkata area often find that the return on investment is significantly influenced by the local electricity tariff structure. Understanding the current rate per unit of consumption is the primary factor in calculating a realistic payback period. For residential consumers, the payback timeline is generally shorter when the existing electricity tariff is high, as the savings realized from self-generation accumulate more quickly. Commercial properties with consistent, high daytime loads tend to see a more predictable and faster return on investment compared to those with highly variable usage patterns. A practical consideration for potential buyers is to model the system's output against the specific time-of-day consumption peaks. Integrating the system design with the local grid's peak tariff hours can optimize savings, ensuring that the generated power offsets the most expensive units of electricity consumed.
