A general rule of thumb is that you’ll need one watt of solar power for every hour that you want to run your lights. So, if you want to run your lights for 8 hours per day, you’ll need an 8-watt solar panel. Of course, there are other factors to consider as well, such as battery efficiency and cloud cover.
A typical 60-watt incandescent light bulb uses about 0.06 kilowatts (kW) of electricity per hour. This means that a 100-watt solar panel could theoretically power than a 40 watt solar panel. However, incandescent bulbs are being phased out in favor of more efficient options like LED lights that stay on all night.
For example: A 100-watt panel can produce 100 watts per hour in direct sunlight. A 400-watt panel can generate 400 watts per hour under the same conditions. This doesn’t mean they’ll produce that amount all day, output varies with weather, shade, and panel orientation.
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.
