Anyone who has ever had a flat car battery knows how infuriating and time consuming it can be. If you have to buy a replacement or catch a cab, the experience is expensive as well as inconvenient. A solar car battery charger is a simple and inexpensive device that helps to keep a battery fully charged, and so has the potential to save hundreds of dollars and many hours of frustration.
Solar panels contain photovoltaic cells that convert the energy from sunlight into usable electricity. Use of this type of energy is encouraged by governments and environmental groups all over the world. One of the advantages of solar power is its low cost: sunshine is free and panels require little maintenance. Appliances and machinery that are powered by solar energy operate independently of any electricity network, and it can be used in isolated regions where connection to a grid is not possible. In the longer term, widespread use of sunlight to generate power for residential and commercial buildings is hoped to bring about a significant reduction in environmental pollution caused by burning fossil fuel.

Solar car battery chargers are small panels that sit on an automobile dashboard. When plugged into the cigarette lighter or connected directly to the battery, the panel converts energy from the sun’s rays into electrical current. The trickle of current produced when sunshine falls on the panel is sufficient to keep the battery’s level of charge topped up. This type of device is especially convenient for maintaining charge in the batteries of vehicles and boats that are not in constant use.
Many solar chargers for car batteries have LED indicators to show when they are operating. Panels that are more sophisticated have an overcharge prevention function that turns the device off when a fully charged state is reached. If you want to avoid being let down by a flat battery, purchasing an environmentally friendly charger could be a very shrewd investment.
