# Accurate Solar Powered Calculators

The Solar Powered Calculator is an online tool that can be used to calculate the energy output of any solar panel, and it can calculate multiple solar panels.

Enter the specifications of the solar panel and the environmental conditions to calculate the solar energy produced per day.

### What is a Solar Powered Calculator?

The Solar Powered Calculator is an online tool that helps you to calculate the energy output of a solar panel based on its capacity and the weather conditions for each day and month. This tool uses an algorithm that can calculate with approximately 99% accuracy, depending on the provided weather conditions, shading, and solar panel efficiency.

### How to use Solar Powered Calculator Tool?

The Solar Powered Calculators online tool requires some specific details about the solar panel, such as its efficiency rating and the weather conditions, in order to estimate the actual electricity or solar energy generated per day and per month. Below is a brief guide on how to fill out the required fields to calculate solar panel energy:

1. Solar Panel Wattage Rating (in Watts): Enter the wattage rating of the solar panel in watts. This information can usually be found on the solar panel itself or in the product specifications, such as 172 watts, 320 watts, 400 watts, or 520 watts.
2. Solar Panel Efficiency:

Enter the efficiency of the solar panel as a percentage. You can determine its efficiency based on whether it is old or new. A new panel will have a peak efficiency of 100%. If you don't know the age of the panel, you can estimate its efficiency by considering how old it is, such as 2 years, 4 years, or 10 years. The efficiency rating will range from 0% to 100%. If the panel is new, its efficiency will be 100%.

However, if it is old, like 10 years, its efficiency will decrease by 5% to 50% depending on the quality and technology of the solar panel. Note that the efficiency of a solar panel also depends on the quality of the panel, the type of solar cell technology used, and the operating conditions, and also 0% to 100% efficiency of a solar panel used our tool algorithm to determine result, so actual sollar panel efficiency is between 15% to 24%, depend on technology.

3. Temperature:

Enter the temperature at which a solar panel will operate, it should be within the range of -20°C to 50°C.

However, if the temperature falls below 0°C and is between 0°C to -20°C, the tool may still calculate the energy production based on that temperature, assuming that the weather is sunny and other operating conditions are optimal. However, if the weather conditions are not normal, such as when it is cloudy or there is no direct sunlight, the solar panel may not generate energy as efficiently, and the tool may not be able to accurately predict the energy production in this condition you can also use shadding percentage to get accurately results.

4. Shading: Enter the shading percentage as a value between 0 to 100. This represents the amount of shading that the solar panel will experience like wall or tree or weather.
5. Average daily sunlight hours: Enter the average number of daily sunlight hours in your location. This can be found by searching for your location's average daily sunlight hours online or by consulting a solar energy expert or you can also estimate.
6. Click on the "Calculate" button to calculate the energy produced by the solar panel based on the input values and the result will be display below.
