One of the primary reasons for the surge in residential solar is the declining cost of solar technology. Over the past decade, the price of solar panels has dropped dramatically, making the upfront investment more feasible for the average homeowner. Increased competition among residential solar companies has also led to innovations that improve efficiency and lower installation costs, making solar energy accessible to more people.
Financial considerations also play an essential role in the adoption of off-grid solar systems. While the initial setup costs for solar panels, batteries, and inverters can be substantial, these systems often lead to long-term savings. In many cases, off-grid systems provide a lower total cost of ownership compared to traditional energy sources, particularly in regions with high electricity prices. After the initial investment, the operation and maintenance costs are relatively low, and homeowners can benefit from energy savings over time.

1. Technology Different types of solar cells, such as monocrystalline, polycrystalline, and thin-film, have varying efficiencies. Monocrystalline panels are known for their higher efficiency and can produce more power in a smaller size. Conversely, polycrystalline panels are generally larger for equivalent output, requiring more roof space.

Residential solar is more affordable than ever, especially with the extension of the federal residential solar tax credit. Taxpayers can claim a 30% tax credit on the cost of solar systems on their income taxes. But be sure to install before January 1, 2033, when the tax credit is set to decrease to 26%.
