SNM Solutions successfully completed this 4kW Hybrid Solar System installation in DHA Phase 6, Lahore for a residential property looking for a practical solution to manage daily electricity consumption and power interruptions.
The system was planned around two main requirements: generating solar electricity during the day and providing backup power for essential household loads when grid electricity is unavailable. By combining solar generation with battery storage, the homeowner can make better use of available solar energy while reducing dependence on conventional grid electricity.
Installed Solar Equipment
- 4.2kW Fronus Hybrid Solar Inverter
- 645W SNM High Efficiency Solar Panels
- 2 × TX 2500 Tubular Batteries
- Standard Mounting Structure
- Professional Electrical Installation
- Complete Electrical Protection and Monitoring System
Expected Solar Energy Production
- 16+ Units Per Day
- 500+ Units Per Month
- 6,100+ Units Per Year
How the Solar System Works
During daylight hours, the 645W SNM High Efficiency Solar Panels generate electricity that can be used to meet the home’s active energy requirements. This helps the property use solar power directly and reduces the need to purchase electricity from the grid during the day.
The 4.2kW Fronus Hybrid Solar Inverter manages the available solar power and supports the battery backup system. The two TX 2500 tubular batteries store energy for use when grid electricity is unavailable, allowing selected household loads to continue operating during power interruptions.
This setup provides a balanced approach to residential energy management by combining solar generation with battery backup in one system.
Key Project Benefits
- 16+ units of estimated solar generation per day
- Reduced reliance on conventional grid electricity
- Solar power generation during daylight hours
- Battery backup during power interruptions
- Better management of household electricity consumption
- Improved use of available rooftop space
- Greater flexibility during load shedding
- Clean electricity generated at the property
- Reduced exposure to increasing electricity costs
Project Outcome
The 4kW Hybrid Solar System in DHA Phase 6, Lahore provides the homeowner with a practical energy solution designed around everyday residential requirements. The system generates solar electricity during the day while the battery bank provides additional support for essential loads when grid power is unavailable.
This project also demonstrates that a properly sized solar system can provide meaningful energy savings and backup without requiring an oversized installation. By selecting suitable equipment and planning the system according to the property’s actual electricity needs, SNM Solutions delivers reliable and efficient residential solar solutions.
A Practical Residential Solar Solution
What this system generates, and what that is actually worth
The design output is 16+ units a day, or about 500 units a month. What those units are worth depends almost entirely on when they get used, and since 9 February 2026 that gap is wide.
A unit consumed in the house replaces one bought from LESCO at roughly Rs 55. A unit exported earns about Rs 11 under net billing. So a self-consumed unit is worth around five times an exported one, and the same 500 units can be worth very different amounts:
| How the 500 units are used | Value per month |
|---|---|
| Everything used in the house as generated | Rs 28,000 |
| 70% self-consumed (loads shifted to daytime, or battery) | Rs 21,000 |
| 40% self-consumed (typical home, nobody in during the day) | Rs 14,000 |
That is a Rs 13,000 a month difference on the same hardware and the same roof. Running the washing machine, water pump, iron and air conditioning during daylight is not a minor optimisation under net billing. It is most of the return.
Figures are the system’s design output at a Rs 55 self-consumption tariff and the Rs 11 export rate. Actual generation varies with season, shading and dust, and your own tariff depends on your slab.
