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.

3. Divide your solar system size (in W) by your desired panel wattage. For this example, I''ll use a solar panel wattage of 350 watts. 3,000 W ÷ 350 W = 8.57 panels. 4. Round up to the nearest whole number. 8.57 rounded up = 9 panels. So, in this example, you''d need 9 350-watt solar panels for a 3 kW solar system on your roof.
Street lighting accounts for a large percentage of total energy consumption worldwide. Street lights are being used for public and residential lighting and they vary in size and consumption depending on the purpose of lighting. Considering the fact that a modern LED street light unit generally consumes about 80 Watts of power, this is a domain that needs immediate …
The size of the solar panel determines its specific use and the type of energy system it is best suited for: Small portable panels are better suited for small off-grid applications, such as powering the lights and air conditioner in your outdoor cabin, RV, or boat.
The solar street lights with battery are economically friendly and cost-effective, Generally, the battery types to be considered are: Deep cycle VRL batteries; Lead-acid battery and SMF ; A lithium-ion battery or Li-ion; Lithium …
For solar street lights with a pole height of 12 meters, a longitudinal spacing of 30-50 meters between street lights should be ensured. Symmetrical lighting should be used on both sides and the width of the road lighting needs to exceed 15 meters.
Use our solar panel size calculator to find out the ideal solar panel size to charge your lead acid or lithium battery of any capacity and voltage. For example, 50ah, 100ah, 200ah, 120ah. For example, 50ah, 100ah, 200ah, 120ah.
The answer depends on the type of light, the wattage of the bulb, and the number of hours the light will be used. A typical 60-watt incandescent light bulb uses about 0.06 kilowatts (kW) of electricity per hour. …
The average US home needs between 13-19 solar panels to fully offset how much electricity it uses throughout the year. This number varies based on your electricity usage, sun exposure, and the power rating of the solar panels. Use the equation below to get an estimate of how many solar panels you need to power a house.
While the upfront cost for a solar street light might be higher than traditional street lights, they give more advantages in the long run. A great tip is to source solar street lights from reliable manufacturers as they offer cheaper prices for bulk orders. HeiSolar is an all-in-one solar street light manufacturer in China.
