Energy is a basic and vital for sustainable economic development of any developing country including Pakistan. A renewable energy solution for the energy crisis in a densely populated city of Lahore, Pakistan is presented in this article. PVsyst software is used to design a stand-alone PV system to tailor the basic energy demand for household requirements. Geographical and climatic study exposes that Pakistan has enormous potential of solar energy with average value of 5-6 kWh/m²/day or 1800-2200 kWh/ m²/annum. Accordingly, present research proved that this technology is a viable clean energy source. The modelled system has met the maximum demand using nominal space on roof top along with battery storage, leaving sufficient space for further expansion of the system to meet increase energy demand. As a result, the system has shown a promising sign and proves its feasibility for the region with energy loss consideration.
