Costs vary based on system size and type. As a general guide: a 5 kW off-grid residential system starts around PKR 6–9 lakh, while a 10–15 kW on-grid system for larger homes or small businesses ranges from PKR 10–20 lakh. Commercial/industrial systems (30 kW+) are priced on requirement. We provide a free site assessment and detailed quotation — contact us for an accurate figure for your specific need.

On-grid connects to WAPDA/K-Electric — you use solar during the day and draw from the grid at night. Cost-effective, no batteries needed, and eligible for net-metering. Off-grid operates independently with battery storage — ideal for areas with frequent load-shedding or no grid access. Hybrid does both: stays grid-connected but also stores excess energy in batteries for backup. We help you choose the right type based on your location, budget, and load requirements.

A standard residential installation (5–15 kW) typically takes 4–5 working days from start to commissioning. Larger commercial or industrial systems (30 kW+) may take 1–3 weeks depending on structural work required. We handle all technical design, structure fabrication, installation, and commissioning in-house.

Yes — we offer scheduled maintenance, panel cleaning, wiring inspection, and system performance monitoring for all solar installations, including systems not originally installed by us. In Karachi's dusty climate, panels lose 15–25% efficiency without regular cleaning. We recommend servicing every 3–6 months for optimal output.

Yes — we serve both sectors. On the residential side we handle solar installations, HVAC, and civil works. For commercial and industrial clients we undertake large-scale mechanical, electrical, civil, and energy consultancy projects. Our clients include power utilities like K-Electric, multinationals like Novo Nordisk, and private sector enterprises across Karachi.

Our primary base is Karachi, but we undertake projects across Pakistan. Large industrial or energy projects in other cities or provinces are evaluated case by case. Contact us with your project location and scope and we'll advise on feasibility.

We provide installation, commissioning, maintenance, and repair of air conditioning, refrigeration, cold rooms, ventilation systems, boiler plants, heat exchangers, absorption chillers, and hot water systems. We serve both light commercial setups and heavy industrial HVAC infrastructure.

Yes — our civil engineering division handles general civil works, building renovation and conservation, concrete repairs, structural reinforcement, waterproofing of basements/roofs/walls, water supply pipelines, and allied mechanical and electrical works. We also create and modify technical blueprints as needed.

NEPRA (National Electric Power Regulatory Authority) regulates electricity supply and pricing in Pakistan. Any power utility, Independent Power Producer (IPP), or large energy consumer dealing with tariff disputes, O&M cost submissions, or regulatory filings may need this service. We have directly assisted companies like K-Electric in preparing tariff imposition requests covering operations & management (O&M) costs, variable costs, and fixed cost documentation submitted to NEPRA.

An energy audit is a detailed survey of how your facility uses energy — identifying waste, inefficiencies, and opportunities to cut costs. Given Pakistan's high and volatile energy tariffs, most commercial and industrial businesses benefit significantly from an audit. It typically identifies savings of 10–30% on energy bills and is often the first step before investing in solar or HVAC upgrades.
