What is needed to run my home on solar energy? Using solar energy for the house
There are several different companies that have to understand what it takes to run my home on solar electric power. There are three different systems to choose from: a grid-tied system, a grid-tied system containing a battery backup, and a stand-alone system. Each will have slightly different needs and materials, although the main part of the system, the solar connection and the conversion will be the same.
The main parts of a grid interconnected system include the PV array, the DC disconnect from the array followed by an AC breaker panel, then connected to an inverter monitored by a kilowatt hour meter and finally connected to your home and to/from the public network.
The battery backed grid will have a PV array, charge controller, array DC disconnect, system meter, battery bank, inverter, main DC disconnect, breaker panel, meter and connects to your home and to/from the utility network.
Off-grid or standalone systems are typically found in rural areas, they can be used anywhere. Components required for an off-grid system include the PV array, charge controller, array DC disconnect, battery bank, main DC disconnect, system meter, inverter, control panel, AC breakers, the backup generator, and a connection to your home.
Each component has an important function. Photovoltaic panels are where sunlight is converted into electrical current. The semiconductor material is what makes this happen through the photovoltaic effect. Typically you will need to mount this array in a rack or on your ceiling so that it is away from any shadows and is not affected by daily life such as children playing.
The DC disconnect is necessary if you must interrupt the flow of electricity and is primarily important for troubleshooting. This discount works like a circuit and can even use fuses. There is another breaker box that does the same thing in your home so you can turn off the electricity in different parts of your home.
