Solar Panel Calculation

Solar panel calculation is the most fundamental preparation stage for every solar power plant (GES) project. First, the energy consumption amount and the corresponding system kW value are determined. Based on these details, the required installation area and the number of solar panels can be decided. Subsequently, the solar panel calculation is completed by considering the sunlight duration and many other details.

Various formulas are used to calculate the costs of solar systems and shape the project structures. Tools that integrate these formulas are utilized to achieve accurate results and minimize the margin of error. The solar panel calculation program (simulator) is the most fundamental tool preferred for these processes.

With a solar panel simulator that does not require engineering or technical knowledge, calculations can be performed effortlessly. In this way, you can obtain approximate details for the GES system you plan to use at home, your workplace, or any location.

How to Perform Solar Panel Calculation?

Thanks to the CW Energy Solar Simulator, solar panel calculations can be easily performed with simple or advanced mode options. This tool, which provides approximate results, allows you to approximately identify your needs for solar system installation.

After accessing the simulator, you can use the "Simple Calculation" option by following these steps:

1. Enter the address to select the installation area and click the "Start Drawing" button.
2. Mark points on the map to determine the installation area.
3. Select one of the structure types such as residential, commercial, industrial zone, or factory.
4. Choose the orientation for the solar system.
5. Select the time period when energy usage is highest.
6. Specify your average monthly energy consumption. Ideally, enter an amount based on the average of your last 12-month electricity bills.
7. Enter a value between 0 and 25° for the roof angle.
8. Finally, click the "Report" button to proceed to the results page.

The calculation process you perform in accordance with the specified instructions will result in the kW value. This value will make the design of the solar energy system easier. In addition, it will be possible to see in the report how many solar panels you need.

The additional details you can learn after completing the solar panel calculation are as follows:

• Roof percentage
• Payback period
• Daily electricity production of the system
• Savings from self-consumption

All the details above are for the "Simple Calculation" mode in the simulator. With the "Advanced Calculation" option, you can obtain more comprehensive results. Details such as specifying the hours when your energy consumption is high and selecting the solar panel can be included. In this way, the solar panel calculation table you obtain contains results that are closer to reality.

Example of Calculating Solar System kW Needs and Costs Using the Solar Panel Calculation Program (Simulator)

In the calculations performed via the simulator, there are fundamental details regarding the determination of system costs and kW values. Selecting the installation area on the map is one of the main details. It should also be noted that the electricity bill is an important detail. With additional information entered into the simulator, an accurate calculation result is obtained.

An example calculation performed using the "Advanced Calculation" mode will make the topic much more understandable. In this way, interpreting the data in the solar panel calculation table will also become easier.

The details of the example calculation process are as follows:

• Location: Antalya
• Building Type: Residential
• Roof Orientation: South
• Solar Panel: CW Energy 545 Wp 108PM M12 HC-MB Solar Panel
• Electricity Usage Rates: Morning (06:00 - 12:00) 27% / Noon (12:00 - 18:00) 61% / Night 12%
• Electricity Purchase/Sale Price: 1.6 / 1.5
• Annual Electricity Consumption: 20,000 kWh
• Roof Angle: 12°

Considering the maximum installation capacity, the system is estimated to have a capacity of 141.7 kWp. The cost will vary depending on the payback periods, the number of panels used, the installation area, and the processes involved.

Solar Panel Calculation Table

The solar panel calculation table is important for determining the design, cost, installation, and other details of solar systems. It includes the number of panels to be used, the amount of power to be produced, the payback period, and many other details.

With the CW Energy Solar Simulator, you can obtain a detailed solar panel calculation table. This allows you to explore all the details of the solar system you plan to install. The appearance of the table obtained from an example calculation is as follows:

The table above contains estimated data for the solar panel system that will meet your energy needs. To achieve accurate results, an on-site inspection of the installation area and structure is required. With the field data obtained, much more accurate results can be achieved for the solar panel calculation process.

Solar Panel Calculation for Homes

With the CW Energy Solar Simulator, you can locate your home and designate your roof as the installation area. Then, by entering details about electricity usage, roof angle, and orientation into the simulator, you can perform solar panel calculations for your home.

Based on annual, monthly, and daily energy consumption, you can access approximate data regarding the appropriate size of the solar system for your home. With the "Advanced Calculation Mode" included in the simulator, you can also determine special details such as panel selection. Thus, the estimated data you obtain will be more accurate, and the calculation table's data will be more detailed.

Frequently Asked Questions About Solar Panel Calculation

How Many Solar Panels Are Needed for 10 kW?

The number of solar panels required for a 10 kW system varies depending on the type and size of the panel. Under normal conditions, 23 CW Energy TOPCon solar panels of 435 Wp will suffice for a 10 kW system. Alternatively, 17 solar panels of 590 Wp can meet the system's 10 kW energy requirement. For both solar systems, an installation area of 45-50 m² will be sufficient.

How Many Solar Panels Are Needed for 1 kW?

The number of solar panels needed for a 1 kW system varies depending on the type and size of the panel. For example, 3 TOPCon solar panels of 435 Wp are sufficient for such a system. If 590 Wp TOPCon solar panels are used, 2 panels will generate the required energy. The total installation area will range between 5-7.5 m².

How Many Panels Are Needed for 3000 Watts?

For a solar system with a 3000 Watt energy requirement, 7 TOPCon panels of 435 Wp can be used. If 590 Wp TOPCon solar panels are used, 6 panels will suffice. The space required for a solar system meeting 3000 Watt energy needs will range between 15-20 m².

How Much Electricity Does 100 Square Meters of Solar Panels Produce?

The electricity generated by a solar panel system installed in a 100 square meter area depends on many factors, including geographic conditions, panel type, installation angle, daily sunlight hours, and more.

If a 100 m² area is considered and 435 Wp TOPCon solar panels are chosen, 45 to 51 panels will be required. The energy produced will range between 19.5-22 kWh.
