When it comes to solar lighting, lumens play an important role in determining how bright the light will be. Simply put, lumens measure the amount of light emitted by a source, such as a light bulb or solar panel. The higher the number of lumens, the brighter the light will be.
Lumens and brightness are directly related, as lumens are used to measure the perceived brightness of a light source. The more lumens a light source emits, the brighter it will appear to the human eye.
The wattage provides the needed power from the solar power and battery system to power the solar light fixture for the required amount of time and the Lumens determines how much light is given off by the lamp. The more efficient the fixture or lamp is, the more efficient the solar and the lower the cost of the complete system.
Changing the light intensity incident on a solar cell changes all solar cell parameters, including the short-circuit current, the open-circuit voltage, the FF, the efficiency and the impact of series and shunt resistances.
Solar lighting needs to take into consideration both the Lumens and the Wattage of a lamp. The wattage provides the needed power from the solar power and battery system to power the solar light fixture for the required amount of time and the Lumens determines how much light is given off by the lamp.
The old way of looking at how bright a light will be is to look at the wattage, and with incandescent lamps, the higher the wattage the lamp is, the brighter it is. Now we need to focus on the Lumens of the lamp to determine the brightness of the lamp, especially when it comes to LEDs. What does a Watt mean?
The more efficient the fixture or lamp is, the more efficient the solar and the lower the cost of the complete system. Solar lights are also typically lower to the ground and then can produce more lighting with a lower Watt lamp and using a higher Lumen efficiency.

One of the biggest arguments is light Wattage versus the Lumens and determining brightness. The old way of looking at how bright a light will be is to look at the wattage, and with incandescent lamps, the higher the wattage the lamp is, the brighter it is.
Solar cells experience daily variations in light intensity, with the incident power from the sun varying between 0 and 1 kW/m 2. At low light levels, the effect of the shunt resistance becomes increasingly important. As the light intensity decreases, the bias point and current through the solar cell also decreases, and the equivalent resistance ...
