Proper sizing is the most important step in building a solar street light to ensure it will operate reliably over the long term. If you want to learn more about the science of solar sizing, check out our infographic here or download our ultimate solar lighting specification guide.
The size of the solar panel you need will depend on a few factors, including the wattage of the lights and the average amount of sunlight your location receives. 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.
Here are three key factors a properly sized, reliable solar street light depends on: a healthy array-to-load ratio, sufficient battery capacity and backup power, and an efficient LED fixture and operating profile. If you want to explore proper sizing in detail, download our Ultimate Solar Lighting Guide.
A properly-sized solar light means the system has just enough solar wattage, battery capacity, and LED fixture efficiency to operate at the project-required light levels every night for multiple years—all while providing backup power to last in unpredictable weather and without adding unnecessary solar panels or batteries.
Golden rule #1 for sizing a solar light: The amount of energy collected by the solar array during the day (commonly referred to as “energy in”) should always exceed the amount of energy spent by the fixture at night (“energy out”). This golden rule can be expressed as a ratio, which we refer to as the array-to-load ratio, or ALR.
Solar panels produce about 250 watts of power each, so you’ll need between 1,120 and 1,270 watts of solar panels to completely offset your energy usage. Of course, the number of solar panels that you’ll need will also depend on how much sunlight your area receives and the efficiency of your solar panel system.
