On-grid solar

Yes, for day-time savings. On-grid runs your home on solar while the sun is up, cutting the most expensive part of your K-Electric bill. Pakistan has moved new rooftop users to a net-billing model under the NEPRA Prosumer rules, so surplus you export now earns only about Rs 11 per unit, well below the retail rate you pay. The savings now come from using your own solar in the day, not from selling it back. To keep the value of every unit you make, a hybrid or battery system stores it instead.

For safety. A grid-tied inverter must shut down the moment the grid goes out, so it cannot feed power into lines that workers may be repairing. This is a required protection called anti-islanding, not a fault. It also means a basic on-grid system gives you no backup during a K-Electric outage. If staying on through load-shedding matters, you need a hybrid or battery system.

Without storage, surplus day-time power flows to the grid. Under Pakistan's new net-billing rules you are paid a fixed low rate, about Rs 11 per unit, for what you export, and billed normal retail rates for what you draw at night. Anything generated beyond your approved load earns no credit. The most valuable unit is the one you use yourself, which is why we size on-grid systems to match your day-time use rather than to oversell to the grid.

Only easily if the inverter is battery-ready, meaning a hybrid inverter. A basic grid-tied inverter usually has to be replaced to add storage. If there is any chance you will want backup later, we often suggest starting with a hybrid inverter now and adding batteries when your budget allows, with no rewiring. We will flag this at your survey.

As a rough guide, every 1 kW needs about 60 to 70 sq ft of shade-free roof, so a typical home system fits most rooftops. The cost depends on the size and panels your home needs, and prices move with the market, so we give you a fixed, fully itemised quote after a free site survey rather than a flat figure. On-grid is the lowest-cost of the three system types.

Tier-1 monocrystalline panels and a grid-tied inverter from established brands, all with full manufacturer warranties listed in your quote. We size everything to your roof and usage, never a generic package, so you only pay for the system your home actually needs.
