Solar System Design

━ Engineered to Perform

Custom solar system design built around your energy needs

A solar system is only as good as its design. We engineer each system around your consumption, roof space and budget to deliver maximum output and the fastest payback.

Electro Engineering’s design team analyses your energy usage, available roof or ground space, shading and structural conditions to create a system that performs optimally in Pakistan’s climate. Whether on-grid, hybrid or off-grid, every layout is modelled for real-world yield — not just nameplate ratings.

We size the panels, inverter and battery precisely, plan the wiring and structure, and produce a clear single-line diagram and proposal so you know exactly what you’re getting and what it will save you.

What our design service includes

How we size a solar system

Good design starts with your electricity bill. We look at your monthly units, when you use power during the day, and which loads must keep running during load-shedding. From there we size the panels to your roof space and consumption, choose an on-grid, hybrid or off-grid inverter, and size any battery to your backup needs.

What you receive

A recommended system size: panel capacity, inverter rating and battery storage where needed.
A panel layout and structure plan for your roof or ground.
A single-line diagram (SLD), which is also needed for net metering.
An estimate of generation and bill savings, with the assumptions explained.

Design choices we explain

On-grid or hybrid, single-phase or three-phase, low-voltage or high-voltage batteries, and whether to leave room for future expansion. You get clear advice, so you can compare quotes on the same basis.

━ Good to Know

Solar System Design FAQs

Common questions about our solar system design service.

What's the difference between on-grid and hybrid?

On-grid systems work with the grid and net metering but not during outages; hybrid systems add a battery so you keep power during load-shedding. We help you choose based on your needs.

How do you size my system?

We analyse your past electricity bills and daily usage pattern, then size the panels, inverter and battery to match — balancing output, budget and available space.

Will you provide a single-line diagram?

Yes. Every design includes a professional single-line diagram (SLD) and layout, which is also required for net-metering applications.

Can the system be expanded later?

We can design your system to be expandable, leaving room to add panels or battery storage as your needs grow.
