S4F Light Weight Model
Complete Solar Power System
Extended range
Longer battery life
Savings on electricity bills
Easy installation and care
Attractive Return on Investment
CO2 emission-free charging and driving
Easy Installation and Care
Retrofits on most electric golf cars and utility vehicles
Easy to install on top of the original canopy
Transferable to new golf fleets when time comes
No demands for structural alterations, installs directly using screws or Velcro*
* Use screws if you want a permanent installation and velcro if you want a temporary solution with fast and easy removal or transfer to a different car. Accessories for both choices are included as standard.
No maintenance except for cleaning the solar panel from time to time
The standard S4F 130 W system fits perfectly on top of a 2 - 4 seater car. For longer or wider cars up to 4 panels can be combined.
Highly Efficient and Reliable
The S4F is made with highly efficient back contact solar cells giving the system the lead in power per square inch. This is crucial to optimize solar power on cars having limited surface area.
The strong polymer lamination enclosing the solar cells is very durable and actually allows higher light penetration compared to glass.
The standard S4F kit supplies up to 130 W solar power. For higher demands, up to 4 x S4F panels can be combined resulting in impressive 520 W*
The controller comes in versions optimized for 24, 36, 48, 60 or 72 V
Low weight - ONLY 3 kg/7 lbs all included
Instead of the usual tempered glass, the solar cells in the S4F system have been protected in a very strong polymer lamination.
The weight reduction is 75 % compared to glass! The S4F weighs only 3 kg/7 lbs including controller, wires and accessories.
In addition the polymer lamination technique adds flexibility, allowing the panel to be easily installed on surfaces with a slight curve.
Nano Protection
The electronic components inside the MPPT have been treated with a special nano coating offering complete water resistance.
For even better performance and durability we also offer the S4F solar panel in a special version with nano treatment. The added advantages are:
• Longer life compared to glass panels • Saltwater resistance • Dust and dirt resistance
MPPT Enhanced Power
SolarDrive’s proprietary MPPT technology ensures maximum power production in all situations and the LCD display at the controller keeps the driver constantly informed about the system’s performance.
Theoretical Life Cycles
DOD (Depth of Discharge)
Impact of Depth of Discharge
The SolarDrive S4F solar systems will help prevent deep discharges. Opposed to the normal grid charger, the solar system will charge batteries during the drive. The more solar power the more positive effect on battery life.
Extended Range
The S4F solar system will make you car drive longer or allow your batteries to remain at a higher state of charge – or both.
Significant CO2 savings
CO2 reduction: 1 S4F = 15 trees
A typical electric golf car powered by SolarDrive S4F will save the electricity equivalent of 200350 lbs. of CO2 annually.*
We would have to plant up to 15 trees to achieve the same level of CO2 reduction.**
In other words a golf club with a fleet of 80 cars would have to establish a small forest consisting of up to 1200 trees covering several acres to achieve the same carbon emission savings that can be achieved through equipping their fleet with the SolarDrive S4F
