Solar for Shops, Clinics and Small Offices

The short version

Small commercial premises are often a better fit than houses — your load runs in daylight, which is exactly when the array produces.
Commercial tariffs are higher per unit, so every unit you avoid buying is worth more.
A 10 kW array needs roughly 550 to 700 sq ft of clear roof. Many shops need less capacity than their bill suggests.
If you hold stock that must stay cold, settle the backup question first — it decides the system type before anything else.
Renting? Have the landlord conversation before you get a quotation, not after.

Most solar marketing in Pakistan points at two audiences: houses and factories. The businesses in between — shops, clinics, pharmacies, salons, small offices, private schools, guest houses — get almost no attention, despite frequently having the best case of anyone.

Why small commercial premises suit solar

Short answerBecause your consumption happens while the sun is up. Lights, air conditioning, refrigeration, computers and equipment all run through business hours. Under net billing the value is in consuming your own generation rather than exporting it, so a load profile that sits in daylight is worth more than a bigger roof.

The shaded overlap is where the saving is. On a shop or clinic running 10am to 8pm, that overlap covers most of the working day.

Add the second factor — commercial tariffs are generally higher per unit than domestic ones — and each unit you stop buying is worth more than it would be at a house. The mechanism behind all of this is set out in net metering to net billing.

The question to settle first

Before system size, before price, before anything: what must keep running when the grid goes down?

Business	What usually cannot stop	Implication
Pharmacy	Refrigerated stock	Hybrid, no argument
Clinic or lab	Sample storage, equipment	Hybrid, sized to a defined list
Restaurant, bakery	Freezers, chillers	Hybrid
Retail shop	Lights, fans, POS	Hybrid if footfall depends on it
Office, salon	Usually nothing critical	On-grid is often enough

A plain on-grid system shuts down the instant the grid does — that is a safety requirement, not a fault, and we explained it in on-grid, hybrid or off-grid. For anyone holding perishable stock, that single fact decides the system type and a good part of the budget.

Tell us what your business runs and when

Your opening hours, what must stay cold or live during an outage, and three months of bills. That is enough for a system type and a realistic size before anyone quotes a price.

What about the roof?

Small premises are often short of roof, and that is usually solvable rather than fatal.

Size to the roof, not to the bill. A 7 kW system that fits properly beats a 10 kW system crammed in with no walkways.
Use the car porch or the shed. We manufacture the structures for both, and a porch array often has better access for cleaning than a roof does.
Higher wattage panels fit more capacity into the same area, which matters when area is the constraint. The arithmetic is in how much roof you need.
Check the structure. Many commercial buildings have older roofs that were not built with an array in mind.

If you rent the premises

This stops a great many small businesses, and it should not. There are three workable structures, and all of them start with a conversation rather than a quotation.

The landlord funds it and the rent is adjusted. The building gains a permanent asset; you get a lower running cost.
You fund it, with a written agreement covering what happens at the end of the lease — whether it stays, whether you remove it, or whether the landlord buys it at a stated value.
You size it to the remaining term, so the system pays for itself within the time you are certain of staying.

What does not work is installing on a rented roof with nothing written down. We have seen that end badly enough times to raise it before anyone talks about panels.

The practical checklist

Three to six months of bills, so we can see your load and your tariff category
Your sanctioned load, which caps the system size you may install
Opening hours, and whether you run seven days

Roof access, and whether the building is owned or rented
Whether a generator is already in place — if so, see solar and a generator

Small business solar: questions people actually ask

Is solar worth it for a shop or a clinic?

Usually yes, and often more than for a house. Small commercial premises run their load during daylight — lights, air conditioning, refrigeration, equipment — which is exactly when the array produces. Under net billing, where the value is in consuming your own generation rather than exporting it, that daytime pattern is what makes the arithmetic work.

How much roof does a shop need?

Less than most owners assume, because commercial systems are often smaller than domestic ones despite larger bills. A 10 kW array needs roughly 550 to 700 square feet of clear roof. Where the premises has no usable roof, a car porch, a shed or a rented rooftop are all worth exploring.

What if I rent the premises?

Then the conversation is with the landlord, and it is worth having. Options include a landlord-funded system with rent adjusted, a tenant-funded system with a written agreement about what happens at the end of the lease, or a shorter payback system sized to your remaining term. What does not work is installing without an agreement and hoping.

Will solar keep my refrigeration running during load shedding?

Only if the system has batteries. A plain on-grid system shuts down when the grid does. For a clinic, a pharmacy or anywhere holding stock that must stay cold, this is the question to settle before anything else, because it decides the system type and the budget.

Does a commercial tariff change anything?

Yes. Commercial tariffs are generally higher per unit than domestic ones, which means each unit you avoid buying is worth more. It also affects the application, since capacity is tied to your sanctioned load. Both belong in the survey rather than in a phone estimate.

The bottom line

If you run a business that consumes power during the day on a commercial tariff, you are close to the ideal customer for solar under the current rules. Settle the backup question first, size to the roof rather than the bill, and if you rent, get the agreement in writing before anything is mounted.
