Restaurants can have high electricity consumption because they often operate ACs, refrigerators, freezers, kitchen equipment, exhaust systems, lighting, water pumps and other electrical appliances for long hours.
A properly designed solar system can help restaurants reduce their dependence on grid electricity and lower operating costs.
For restaurants that also experience power outages, a hybrid solar system with battery storage can provide backup for selected essential loads.
Why Should Restaurants Consider Solar?
Electricity is one of the ongoing operating expenses for many restaurants.
Solar can help reduce the amount of electricity purchased from the grid by generating power during daylight hours.
A restaurant may use solar to offset the consumption of:
- Air conditioners
- Refrigerators
- Freezers
- Kitchen equipment
- Exhaust fans
- Water pumps
- Lighting
- POS systems
- Computers
- CCTV systems
- Other electrical appliances
The potential savings depend on the restaurant's actual consumption, operating hours and solar-system design.
What Size Solar System Does a Restaurant Need?
There is no single solar capacity suitable for every restaurant.
A basic starting guide could be:
| Restaurant requirement | Possible solar capacity |
|---|---|
| Small restaurant / café | 10kW--20kW |
| Medium restaurant | 20kW--50kW |
| Large restaurant | 50kW--100kW+ |
These are general planning ranges, not fixed recommendations.
A restaurant's electricity bills and actual load should be assessed before selecting the system.
A restaurant with several ACs and heavy kitchen equipment may require considerably more capacity than a similarly sized café.
On-Grid or Hybrid Solar for a Restaurant?
On-Grid Solar
An on-grid system is generally appropriate when the main objective is:
Reducing electricity bills
Solar power is used alongside the grid without requiring a large battery bank.
Hybrid Solar
A hybrid system is more suitable when the restaurant also needs:
Electricity savings + backup power
Battery storage can support selected critical loads when the grid is unavailable.
For example, backup may be prioritized for:
- Refrigeration
- POS systems
- CCTV
- Internet equipment
- Essential lighting
- Selected kitchen equipment
- Other critical loads
Running the entire restaurant on batteries during a prolonged outage can require a substantially larger battery investment.
How Much Solar Does a Restaurant Need?
The correct system should be based on the restaurant's actual electricity consumption, rather than simply its floor area.
Important factors include:
- Monthly electricity units
- Number of ACs
- AC capacity
- Kitchen equipment
- Refrigerator/freezer load
- Operating hours
- Daytime consumption
- Peak simultaneous load
- Available roof area
- Backup requirements
- Future expansion
For example, a restaurant operating primarily during daylight hours may be able to make particularly effective use of its solar generation.
Restaurant Solar System Design
A commercial solar installation should be designed around the property's actual electrical infrastructure.
The system may include:
Solar panels → inverter → restaurant electrical system → grid
For hybrid installations:
Solar panels → hybrid inverter → loads + battery + grid
The design should also account for:
- Proper cable sizing
- AC/DC protection
- Earthing
- Surge protection
- Mounting structure
- Inverter capacity
- Battery capacity where applicable
- Safe integration with the existing electrical system
Can Solar Run Restaurant ACs and Kitchen Equipment?
Yes, but the system needs to be appropriately sized.
Restaurant loads can be significantly higher than those of a typical home.
Large loads may include:
- Multiple air conditioners
- Commercial refrigerators
- Deep freezers
- Ovens
- Grills
- Exhaust systems
- Water pumps
- Commercial kitchen equipment
These loads should be assessed individually.
A 20kW restaurant system, for example, should not be assumed to run every appliance simultaneously just because the system is rated at 20kW.
The inverter, appliance loads and operating schedule all matter.
How Much Roof Space is Required?
Commercial restaurants can sometimes have useful rooftop space, but the usable area needs to be assessed carefully.
The available space may be affected by:
- Water tanks
- HVAC equipment
- Staircases
- Signage
- Parapets
- Shade
- Roof structures
- Maintenance access
A site survey can determine how many panels can realistically be installed.
What About Restaurant Solar System Pricing?
There is no single price for a commercial restaurant solar system.
The total cost depends on:
- System capacity
- Panel brand and wattage
- Inverter type and brand
- Battery capacity
- Mounting structure
- Protection equipment
- Cabling
- Installation
- Roof conditions
- Electrical infrastructure
Panel, inverter and battery prices can also change regularly and vary between brands.
Premier Solar Solutions can provide current equipment options and a project-specific quotation instead of relying on outdated component prices.
Is Solar Worth It for a Restaurant?
For a restaurant with substantial and consistent electricity consumption, solar can be a worthwhile investment because it can reduce grid electricity consumption over the long term.
The business case becomes particularly interesting when the restaurant has:
- High monthly electricity bills
- Significant daytime consumption
- Multiple ACs
- Commercial refrigeration
- Large kitchen loads
- Adequate rooftop space
The actual return on investment should be calculated from the restaurant's electricity bills and proposed system, rather than using a generic payback period.

Frequently Asked Questions (FAQs)
Is solar suitable for restaurants?
Yes. Restaurants can be good candidates for solar because they often have substantial electricity consumption from ACs, refrigeration, kitchen equipment, lighting and other loads.
What size solar system does a restaurant need?
It depends on the restaurant's electricity consumption and electrical load. Smaller restaurants may consider 10--20kW systems, while larger establishments may require 50kW or more.
Can solar run restaurant ACs?
Yes. A properly sized commercial solar system can support AC loads. The required capacity depends on the number, size and efficiency of the AC units and other appliances operating simultaneously.
Should a restaurant choose on-grid or hybrid solar?
On-grid is generally more focused on reducing electricity bills. Hybrid is preferable when backup power is also an important requirement.
Can restaurant refrigeration run during a power outage?
Yes, with an appropriately designed hybrid system and sufficient battery capacity. Refrigeration can be treated as a priority backup load.
How much does a solar system for a restaurant cost in Pakistan?
The cost varies according to system capacity, equipment brands, battery requirements, installation and site conditions. A customized quotation is required for an accurate current price.
Final Takeaway
For restaurants, solar isn't simply about installing panels on the roof.
The system should be designed around the restaurant's ACs, refrigeration, kitchen equipment, operating hours, electricity consumption and backup requirements.
For a restaurant with significant electricity consumption, the right commercial solar system can help reduce grid dependence and improve long-term energy costs.
