How much electricity can this system really make?

There's several ways to estimate solar power production. Below, we'll use a simple method to estimate what kind of daily charging rates you can expect in different conditions. Your individual mileage will vary significantly from this depending on location, weather, e-bike efficiency, elevation, sun angle, road shading, temperature, tire inflation, aerodynamics, driver skill and more.

We typically experience 12-18 watt hours per mile (wh/mi)  when testing normal (upright) e-bikes in our area. It's easy to use up to 24wh/mi or more when riding at 750w on the road, or as little as 8wh/mi when aggressively riding more efficient bikes such as recumbents or road bikes. The best way to measure and improve your watt hours per mile is to log it with the Cycle Analyst.

Example 1: 110w panel on a statistically average day of the year in Winston-Salem, NC. 

110w x .70 = 77 watts per hour (70% efficiency at 700w/m²)

x 4.5 usable sun hours = 346.5wh.

12 wh/mi  = 29 miles per day.

/ 24 wh/mi  = 14 miles per day.

 

Example 2: 110w panel, a summer day with exceptional sun and good weather.

110w x .75 = 82.5 watts per hour (75% efficiency at 750w/m²)

x 8 useable sun hours = 660wh.

/ 12 wh/mi = 55 miles per day.

/ 24 wh/mi = 27 miles per day

 

Example 3: 110w panel on a not so sunny day in January

110w x .60 = 66 watts per hour (50% efficiency at 500w/m²)

x 2 useable sun hours (statistical average per year) = 132wh.

/ 12 wh/mi  = 11 miles per day.

/ 24mi/mi = 4-5 mi/day
