Solar energy technologies use the sun's energy and light to provide heat, light, hot water, electricity, and even cooling, for homes, businesses, and industry.
Solar cells convert sunlight directly into electricity. Solar cells are often used to power calculators and watches. They are made of semiconducting materials similar to those used in computer chips. When sunlight is absorbed by these materials, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity. This process of converting light (photons) to electricity (voltage) is called the... read more
A deep-cycle battery is a lead-acid battery designed to be regularly deeply discharged using most of its capacity. Used in renewable energy systems, they are different from car batteries and that difference is critical.
RE systems by nature are cyclical: energy is captured and stored, then later consumed, in a (usually) regular. For example, in a battery-based solar electric system, the energy produced daily by the solar panels is stored in the battery bank, which is then used by loads at night or on not-so-sunny days. This repetitive process subjects the batteries to a slow, daily charge and discharge pattern. ... read more
Solar water pumps are used throughout the world for a number of innovative applications.
If you are in a remote area and the cost of running traditional water piping is cost prohibitive, a solar water pump may be the right solution for your water supply needs. ... read more
