Solar

With a wide range of wattage and chemistry differences between manufacturers and panel sizes you have a huge range to select from, from monocrystalline, polycrystalline, PERC, and thin-film panels. all of which have their own cost and efficiency.

An inverter is one of the most important pieces of equipment in a solar energy system. It’s a device that converts direct current (DC) electricity, which is what a solar panel generates, to alternating current (AC) electricity, which the electrical grid uses.

Solar energy can also be stored in electrochemical batteries. When solar energy is pumped into a battery, a chemical reaction among the battery components stores the energy. The reaction is reversed when the battery is discharged, allowing current to exit the battery.

A charge controller or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery.

A solar lamp, also known as a solar light or solar lantern, is a lighting system composed of a LED lamp, solar panels, battery, charge controller and there may also be an inverter. The lamp operates on electricity from batteries, charged through the use of solar panel (solar photovoltaic panel) Solar-powered household lighting can replace other light sources like candles or kerosene lamps. Solar lamps have a lower operating cost than kerosene lamps because renewable energy from the sun is free, unlike fuel. In addition, solar lamps produce no indoor air pollution unlike kerosene lamps. However, solar lamps generally have a higher initial cost, and are weather dependent. Solar lamps for use in rural situations often have the capability of providing a supply of electricity for other devices, such as for charging cell phones. The costs of solar lamps have continued to fall in recent years as the components and lamps have been mass-produced in ever greater numbers.
