Take your commute completely off-grid!

  • Use solar energy to charge an electric vehicle
  • Scalable depending on geographic location and charging requirement
  • Zero Carbon Footprint
  • Incorporates Maximum Power Point Tracking (MPPT)
  • Proprietary Boost topology allows a single PV module to charge a 48Vdc battery


Take your commute completely off-grid by charging your Electric Vehicle with the Sun’s rays. Alpha Energy has developed a stand-alone solution to charge your electric vehicle. This system can be mounted on an existing structure or on its own stand. Alpha’s solar charger uses proprietary technology that allows the use of a single PV module to charge a 48Vdc battery pack.

Using the Sun Hours per Mile Table
The table below is a guide that approximates how far a BEV Scooter can be driven for each hour of solar charging.
It shows the results for one, two and three Alpha PV165 solar modules.
For example, with one hour of sunshine a single PV module will provide sufficient power to drive a BEV around 2 miles.
It shows that even with a single PV module and a couple of hours of sunshine a day the scooter can be used for carbon-free neighborhood trips.
