Technical FAQs 4

What is solar wattage?

Wattage refers to the amount of electrical power a solar panel can produce under standard test conditions (STC), which simulate a bright sunny day with optimal solar irradiance (1,000 W/m²), a cell temperature of 25°C, and clean panels. In simpler terms, a panel’s wattage rating tells you its maximum power output under ideal conditions.

What are the key specifications of solar panels?

The article covers the key specifications of solar panels, including power output, efficiency, voltage, current, and temperature coefficient, as presented in solar panel datasheets, and explains how these factors influence their performance and suitability for various applications.
