How to Determine a Solar Power Light System

Based on particular information, a series of calculations are run that will determine the appropriate size for the solar panel array. This process is called “sizing” a solar system. Only after a system has been “sized” can the specifics of the system and price be determined.

You Determine:

2.The Application: Different applications need different amounts of light3.Preferred Bulb: Cold Cathode (CCF), Compact Fluorescent (CF), Low Pressure Sodium (LPS) or High Pressure Sodium(HPS)4.Run Time (Duration of the Load): Number of hours you need the lights to be on each night. Examples: Dusk to Dawn, 12 hours, 6 hours, split time controllers (4 hours after dusk & 2 hours before dawn), etc.

5.Fixture Model: We have a variety of standard fixtures available.

We Determine:

2.The Bulb Size: Based on the amount of light you need for your particular application or specific footcandle requirement on the ground3.The Size of the Required Solar Panels: Solar panels typically come in a variety of sizes. We always calculate at least a 10% reserve and round up to the next higher panel size.4.The Size and Number of Batteries: Our systems are sized to work after 3 dark or cloudy days. Additional battery back-up can be added if needed. Besides, we build in a 20% safety factor.

5.Optimal pole spacing and placement to match your specified light requirements.
