Your previous electric appliances may be efficient enough; however, the advanced versions are eco-efficient, which means efficiency and compliance standards for environmental safety. To lower the greenhouse gases, you may run the generator on gasoline instead of diesel for electricity production; however, the solar system is efficient and eco-friendly at the same time. There is no need to pay for diesel or gas as sunlight is a free alternator. The solar arrays power up appliances during the daytime, while the 12v 200ah lithium battery units provide backup power during non-solar production hours.
