Need more power? Our EV ARC™ 4 generates power with a 4.1kW array and is the most powerful EV ARC™ we have ever released. It will make enough clean, renewable energy to power up to 150 e miles each day. If you need to charge several cars or are in a location that gets less sun, the EV ARC™ 4 turns more of the light hitting the EV ARC™ into electricity, so that you can have the best solar powered charging experience possible. This unit is ideal for locations where there will be a high turnover of EVs or if your days are short and the weather is bad.
