There are several benefits of residential solar. Firstly, it helps homeowners save money on their electricity bills by producing their own clean energy. Secondly, it reduces dependence on traditional fossil fuels, leading to a more sustainable and environmentally friendly lifestyle. Additionally, installing solar panels can increase the value of a home and potentially qualify for various tax incentives or rebates.

The cost of residential solar installation can vary depending on several factors, such as the size of the system, location, and available incentives. Generally, the cost includes equipment, labor, permits, and any necessary upgrades to the electrical system. However, it is important to note that the long-term savings on electricity bills often outweigh the initial investment.

Most solar panels come with a warranty ranging from 20 to 25 years, but they can actually last much longer. The degradation rate of panels is usually around 0.5% to 1% per year, meaning they can continue to produce electricity for several decades. It is not uncommon for solar panels to have a lifespan of 30 years or more.

Solar panels generate electricity during the day when sunlight is available, but they cannot directly produce power at night. However, homeowners can utilize a solar battery storage system to store excess energy generated during the day for use at night. Alternatively, homes can remain connected to the grid and draw electricity during the night, with any surplus solar energy generated during the day being fed back to the grid.
