Pakistan Advanced Solar Calculator 2026: Get a Smarter Solar Estimate with UA Solar
Planning solar shouldn't start with a random system size or a rough price.
Your electricity usage, location, utility company, appliances, roof space, backup requirements, solar generation, and investment all matter before you choose a system. UA Solar Solutions has built an advanced solar calculator that brings these important details together in one practical planning tool.
The calculator is designed for customers across Pakistan. You can use your electricity bill, monthly units, appliance load, location, and roof information to create a more detailed preliminary solar estimate.
More importantly, the calculator now includes a roof video analysis feature. You can provide a live video of your roof so the system can use visible roof information as part of the solar planning process.
What Is the UA Solar Advanced Calculator?
The UA Solar Advanced Calculator is a digital solar planning tool created to help you understand your potential solar system before requesting a final quotation.
Instead of calculating only the required kW, it brings technical and financial information into one workflow. You can explore system size, panel quantity, generation, roof requirements, estimated savings, investment, battery options, and financing.
This makes the calculator useful for homeowners, businesses, shops, offices, and larger solar projects that need an initial planning estimate.
How the Calculator Works
The process starts with information about your electricity consumption and property. You can choose the calculation method that matches the information you already have.
After that, the calculator processes your selected location, electricity provider, solar configuration, load requirements, and roof information. It then produces a detailed estimate based on the calculator's technical assumptions.
The goal is simple: give you more useful information before you move toward a professional solar site survey.
Calculate Solar from Your Monthly Electricity Bill
If you know your average monthly electricity bill, you can enter it directly into the calculator.
This gives the calculator a starting point for estimating your electricity requirement and suitable solar capacity. It is especially useful for customers who don't regularly track their monthly units.
Use Monthly Units for a More Direct Estimate
You can also enter your monthly electricity units when that information is available.
Using units or kWh gives the calculator a direct consumption figure. This can make the initial solar sizing process more specific than relying only on the bill amount.
Calculate Your Load with Appliances
Many customers don't know their exact monthly electricity consumption. The appliance-based option helps solve that problem.
You can add common household or commercial loads such as air conditioners, refrigerators, fans, lights, water pumps, washing machines, televisions, microwaves, routers, and computers.
By entering the appliance power, quantity, and approximate operating hours, the calculator can estimate your daily load and use that information for solar planning.
Select Your Electricity Company
Electricity costs and utility arrangements can differ across Pakistan. That's why the calculator includes a utility selection instead of using one generic electricity rate for every customer.
Current options include FESCO, LESCO, IESCO, GEPCO, MEPCO, K-Electric, PESCO, HESCO, SEPCO, QESCO, TESCO, AJK-ED, and GB-ED.
This makes the calculator more relevant for customers living in different electricity distribution areas.
Use the Calculator Across Pakistan
You don't need to live in a major city to use the calculator.
The system is designed to accept locations across Pakistan, including smaller cities and areas that are often ignored by generic online solar calculators.
Your selected location can be used as part of the estimate while the final installation design is confirmed through an on-site assessment.
Choose On-Grid, Hybrid, or Off-Grid
Different customers need different solar configurations. The calculator lets you choose the system type that matches your requirements.
On-grid systems are designed to work with the electricity grid. They are generally suitable when your main goal is reducing electricity costs through solar generation.
Hybrid systems combine solar generation with battery backup. They can be useful when you want lower electricity costs while also maintaining backup during outages.
Off-grid systems are designed for properties that need greater independence from the electricity grid. These projects require careful load and battery planning before installation.
Live Roof Video Analysis
One of the most useful features of the updated calculator is its roof video workflow.
Instead of relying only on the electricity bill, you can provide a video showing your roof. The visible roof information can then be considered during the preliminary solar planning process.
This gives the calculation an additional layer of property-specific information. Your roof is no longer treated as an unknown space when creating the initial estimate.
How the Roof Video Feature Helps
The roof video can help the calculator understand visible conditions and the available roof environment for preliminary planning.
It can support the assessment of usable roof space and help connect your actual property with the estimated solar panel requirement.
The result is intended to give you a more practical starting point than a calculation based only on your monthly electricity bill.
Why Roof Information Matters
A 10kW solar system isn't just a number on a screen. It requires physical space for panels, suitable installation areas, access, spacing, and proper positioning.
Roof conditions can also affect the final installation. Objects, walls, shade, water tanks, structures, and available installation space may change the final panel layout.
That's why combining electricity information with roof information can make the initial planning process more useful.
585W Tier-1 Bifacial Panel Calculation
The current calculator uses a reference configuration based on a 585W Tier-1 N-Type TOPCon Double-Glass Bifacial solar panel.
This reference specification gives the calculator a consistent basis for estimating panel quantity, system capacity, generation, and approximate roof requirements.
The final panel brand and model can change according to the approved project design and equipment availability.
Estimated Solar System Size
After processing your electricity requirements, the calculator estimates the solar capacity that may suit your consumption.
This helps you understand whether your project may require a smaller residential system or a larger installation for higher electricity consumption.
The estimate is a planning figure. Final sizing should be confirmed after checking the actual property and electrical requirements.
Estimated Number of Solar Panels
Knowing the system size is useful, but customers also want to know how many panels they may need.
The calculator converts the estimated system capacity into an approximate panel count using the selected reference panel specification.
This gives you a clearer idea of the physical scale of the proposed solar installation.
Inverter Size Estimation
The inverter is a key part of any solar system.
The calculator includes inverter sizing within the system planning workflow so you can understand the approximate equipment requirement alongside your solar panel capacity.
Final inverter selection depends on the approved system design, electrical characteristics, load profile, and selected equipment.
Estimated Solar Generation
Solar panels don't produce the same amount of electricity every day.
The calculator uses solar resource assumptions and system losses to estimate expected generation rather than presenting an ideal laboratory figure.
This helps you understand how much electricity your proposed system may produce under the selected calculation conditions.
Seasonal Solar Generation
Solar production changes with the season.
The current calculator uses different peak-sun-hour assumptions for annual, summer, and winter conditions. This provides a more useful picture than using one perfect production number throughout the year.
Actual production can still change because of weather, dust, temperature, shading, panel orientation, and installation conditions.
20% System Derating
Real solar systems experience losses.
For that reason, the calculator currently applies a 20% derating assumption. This reduces the theoretical output to create a more practical estimate of expected system performance.
Estimated Roof Area
The calculator also considers the approximate roof space required for the selected panel quantity.
This helps you understand whether the estimated system may physically fit within your available roof area.
However, the calculated roof area should not be treated as a final engineering layout. A professional survey is still required to check actual usable space.
Self-Consumption Calculation
Your solar savings depend partly on how much solar electricity you consume directly.
The calculator includes a self-consumption setting that can be adjusted according to the expected usage pattern. This helps make the financial estimate more realistic than assuming every generated unit is used in exactly the same way.
Export Credit Estimate
If your system exports surplus electricity, the calculator can include an export-credit assumption in its financial calculation.
The current configuration uses Rs. 11.50 per exported unit as an estimation assumption.
This figure is for calculation purposes and should not be treated as a guaranteed future tariff. Applicable utility policies and current commercial arrangements should be confirmed before making an investment decision.
Estimated Monthly Solar Savings
After estimating solar production and electricity usage, the calculator can show an approximate financial benefit.
This helps you understand how the proposed solar system may affect your monthly electricity expense.
Your actual savings will depend on electricity tariffs, consumption patterns, solar production, export arrangements, and system performance.
Estimated Solar Investment
Solar planning is incomplete without understanding the required investment.
The calculator provides an approximate project cost based on the selected system type and reference pricing assumptions.
Actual project pricing can change because of equipment brands, battery technology, installation requirements, mounting structure, wiring, protection equipment, site conditions, and market prices.
Battery Options for Hybrid Systems
Battery storage can significantly change the cost and capability of a hybrid solar system.
The calculator includes battery technology choices such as lithium and tubular options. This helps customers understand the general difference between backup configurations during the initial planning stage.
Final battery capacity should be selected according to the appliances you want to run during an outage and the required backup duration.
Solar Financing Estimate
Customers may also want to understand how solar financing could affect their monthly budget.
The calculator includes an illustrative financing workflow where you can consider financing tenure and down payment assumptions.
It can then estimate the financed amount and approximate installment using the selected calculation assumptions.
Down Payment and Monthly Installment
A higher initial down payment can reduce the amount that needs to be financed.
The calculator lets you explore this relationship so you can understand how the estimated project investment could fit within your budget.
These figures are planning estimates and are not a bank-approved financing offer.
Customer and Site Details
A useful solar proposal needs project information as well as calculations.
The calculator can collect details such as your name, phone number, city, and address. These details connect the estimated system with the property being considered for installation.
Professional Solar Proposal Workflow
The calculator is designed to turn the calculation into a structured proposal instead of leaving you with a single system-size number.
The workflow can bring together technical information, estimated generation, investment, savings, financing assumptions, customer information, and project details.
A proposal reference can also help identify the calculation when discussing the project with the solar team.
PDF Proposal Support
The proposal workflow can also prepare the calculated information in a professional document format.
This gives customers something they can review and discuss before moving forward with a detailed quotation and physical site assessment.
Built for Residential and Commercial Solar Planning
Every solar project has a different electricity profile.
A home may need to focus on air conditioners, fans, refrigerators, lighting, and backup. A business may have a stronger daytime load and different operating hours.
The calculator provides an initial planning framework for different property types. Larger commercial and industrial projects still require detailed engineering and site-specific calculations.
Why This Calculator Is More Useful Than a Basic Solar Calculator
A basic calculator may give you one number and stop there.
The UA Solar calculator connects consumption, appliances, location, utility selection, system type, panel configuration, generation, roof information, savings, investment, batteries, financing, and proposal details.
The roof video feature adds another important layer by bringing visible property information into the preliminary planning process.
That combination makes the calculator more practical for customers who want to understand the project before requesting a final quotation.
What You Should Check Before Installing Solar
An online estimate is a starting point, not a replacement for professional engineering.
Before installation, the roof should be checked for structural suitability, shading, orientation, access, panel positioning, electrical connections, cable routes, inverter placement, and other site conditions.
A professional site survey should confirm the final system size, equipment selection, installation method, and project price.
