To best understand how solar energy can help the modern consumer save money and make responsible choices for a source of power that is truly renewable, a few basic concepts need to be understood when it comes to using a solar heating system.

PV solar panels (PV is short for photovoltaic) are collectors that capture solar radiation or radiant heat from sunlight and convert it to useable energy in the form of electrical current that then can be used to power appliances or other devices within the home or building. Most PV solar panels are connected in arrays that can be either mounted on the roof of a structure, or other places where it will receive the maximum exposure to the sun’s rays. The solar array may then be attached to the electrical system of the house by a cable.

If the house or building is close enough to a utility power grid, it can be added in through a net metering system. This net meter is able to run forwards and backwards so that the consumer can draw wattage from the grid if it is too dark or overcast to generate power. Any overage in wattage generated may be sold back to the grid to be used by other customers.

If a house is not close enough to a utility grid to conveniently hook on, a system of storage batteries can be installed which can store enough electrical current to take care of any power needs until such time as the PV solar panels can capture sunlight again and recharge the batteries. When connected to solar heating systems, photovoltaic solar panels can heat a house or provide hot water.
