In this solar panel specifications guide, we will learn how to read solar panel specifications, like open circuit voltage, wattage, short circuit current, etc., and choose the right panels.

What Are Solar Panels Specifications?

The solar panel specifications sheet includes electric ratings, technical jargon, and many other parameters that determine the efficiency of the solar panel. Usually, you can find the technical specifications of solar panels on the manufacturer’s website.

Before we dig deep into the electrical terms related to solar panels, understanding the difference between solar cells and solar modules is vital. A solar cell is typically 125mm × 125 mm or 156 mm × 156 mm sized silicon wafers combined to form solar modules.

When 60, 72, or 96 solar cells are wired together, they form a solar panel or solar module. Large-size solar panels are suitable for commercial purposes, while small-size panels are best suited for residential applications.

Solar Panel Test Conditions

Commonly, there are two test conditions for solar panels, including:

Standard Test Conditions (STC)

STC is the set criteria for testing the solar panels. As current and voltage are based on light intensity and temperature, all solar panels are tested under the same conditions. In this case, the solar cell temperature is 25°C with a light intensity of 1000 watts per square meter.

Normal Operating Cell Temperature (NOCT)

Unlike STC, NOCT focuses more on realistic conditions. Instead of a light intensity of 1000 watts per square meter, the solar panel intensity is set at 800 watts per square meter. Additionally, it uses an air temperature of 20°C with 1 m/s wind velocity. Though these ratings are lower than STCs, they are much more realistic.

How to Read Solar Panel Specifications?

When it comes to reading the solar panel specifications, you will need to understand all the essential electrical terms. Below we have included all the common electrical terms associated with solar panels.

Wattage on Solar Panel: Wattage means the electrical output produced by the solar panels under standard test conditions. The higher the wattage of the solar panels, the more electricity they can produce in the same time frame.

Open Circuit Voltage (Voc): It represents the maximum voltage of a solar panel when no load is connected to it. Voc will help you determine the number of solar panels you can wire in series without overvoltage or overcurrent issues.

Short Circuit Current (Isc): It is the highest current produced by the solar panel when no load is connected. It helps you estimate how many amps a connected device can handle. In this case, users need to ensure that the plus and minus of the solar panels are connected to each other.

Maximum Power Point (Pmax): It’s the point where a combination of amps and volts results in the highest watts. The MPPT charge controller maximizes the solar panel output by keeping the volts and amps at Pmax or Maximum Power Point.

Maximum Power Point Voltage (Vmpp): The Vmpp determines the point where the power output of the solar panels is greatest. When the solar panels are connected to the MPPT solar charge controller or an inverter under STC, the voltage you see is Vmpp.

Maximum Power Point Current (Impp): The current produced when there is high power output is termed Impp. You can see the Impp when solar panels are connected to the MPPT controller under STC.

Nominal Voltage: It’s not the actual voltage you will measure, but it is a category that lets you define which equipment goes together with the solar panels.

Power Tolerance: It measures the power solar panels produce below or beyond their rated capacity.

Module efficiency (%): It measures how much sunlight hitting the solar panels is converted into electrical energy.

Warranties: Solar panel specifications also mention the warranties. However, they may vary depending on the manufacturer and the quality of the panels.

Temperature Coefficient: It represents the relationship between PV output and solar panel temperature. The temperature coefficient determines the overall percentage decrease in power for each degree of rise in temperature.

Solar Panel Material Characteristics

Based on the electrical ratings and parameters, the solar panel specifications differ depending on the material used in its manufacturing.

Solar Cell & Types

The most common cell types used in solar panels are monocrystalline and polycrystalline silicon cells. However, the former is highly preferred as they are made of a single silicon cell structure rather than multiple silicon cells.


Solar panel dimensions vary depending on the number of cells used. For example, 60-cell solar cells are used in residential areas, whereas larger ones, like 72-cell and 96-cell solar panels, are preferred in commercial spaces.

Wind and Snow Loads

Next, you need to pay attention to the wind and snow loads of solar panels. The high mechanical or static load ratings of the module ensure that the panels can withstand harsh winds and can stand well against all the elements.

Solar Panel Specifications FAQs

What are solar panel warranties?

The warranties on the solar panel differ depending on the manufacturer. For instance, Jackery offers high-quality SolarSaga Solar Panels that come with a 5-year warranty. Buyers get a 3-year warranty on regular purchases, with an additional 2-year warranty extension when ordering from the official website.

How to choose a solar panel?

While making the purchase, you will need to understand the solar panel’s specifications. Below we’ve mentioned some of the most important things you will need to look out for while selecting solar panels.

  • Check the solar panel efficiency to ensure it can convert the maximum amount of sunlight that hits the surface into electricity.
  • The temperature coefficient of the solar panels should be low to ensure they don’t age faster and convert sunlight into electricity faster.
  • Compared to polycrystalline and amorphous solar panels, monocrystalline panels are highly efficient. Therefore, it’s a wise idea to invest in monocrystalline panels with longer lifespans.

Are solar panels worth it?

Solar panels are an excellent way to reduce carbon footprint and protect the planet. You can connect the solar panels to a portable power station to charge a wide range of appliances using free solar energy. However, not all solar systems are the same. You can consider investing in the Jackery Solar Generators, which are robust and powerful charging solutions available on the market.
