Solar Powered products are not costly and are much affordable than the traditional energy products. If proper care is taken, there is no high cost maintenance required. When we say Solar Powered Van or Vehicle, we must first know & understand whether it is motive power we are talking about or the power being used for powering other appliances inside the vehicle. In the latter case,  it is without any doubt efficient and practically implementable solution. We have installed solar panels atop many such mobile vans, ATM vans, mobile libraries etc.
