Key Components of a Solar System
In addition to solar panels, a solar system includes an inverter and batteries. The inverter converts the DC (direct current) electricity generated by the solar panels into AC (alternating current) electricity that can be used in the home. The batteries store excess electricity generated by the solar panels for use when the sun is not shining. A charge controller is also used to regulate the amount of electricity that is sent to the batteries.
Grid-Tied vs. Off-Grid Solar Systems
Grid-tied systems are connected to the electrical grid and allow homeowners to sell excess electricity back to the utility company. Off-grid systems are not connected to the grid and require batteries to store excess electricity for use when the sun is not shining. Off-grid systems are typically more expensive than grid-tied systems because they require more equipment.
Household Solar Costs and Financial Incentives
One of the most significant factors that homeowners consider when deciding whether to install a household solar system is the cost. While the initial investment can be substantial, there are several financial incentives available that can help offset the cost and make solar more affordable.
