For solar lighting, focusing on lumens rather than wattage is key to ensuring you get the brightness you need without overburdening your energy system. Efficient solar lighting systems are designed to produce high lumens with low wattage, using advanced LED technology to achieve bright light while consuming minimal energy.
Solar lights with 15–30 watts and 1000–3000 lumens provide enough light to cover larger areas while ensuring security and visibility. For Streets and Roadways: Street lighting requires even more brightness, with wattage ranging from 30–60 watts and lumen outputs between 3000 and 6000 lumens.
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.
When planning a solar lighting system for a city, park, or commercial property, several factors can help you optimize both wattage and lumens for energy-efficient performance: Solar Panel Sizing: The wattage of your light fixture will determine the size of the solar panel needed to power it.
