Solar panels are devices that convert sunlight into electricity. They are made up of many smaller units called solar cells, typically made from silicon, which harness solar energy and generate power.
Solar panels work by absorbing sunlight, which excites electrons in the solar cells. This creates a flow of electricity. An inverter then converts the direct current (DC) electricity into alternating current (AC) electricity, which can be used to power homes.
Installing solar panels can lower electricity bills, reduce carbon footprint, and increase your home's value. Additionally, many governments offer tax incentives and rebates for solar panel installation.
The cost of solar panels varies based on the size of the system and the brand. On average, residential installations can range from $15,000 to $30,000 before tax incentives. However, prices continue to decrease as technology improves.
Solar panels typically have a lifespan of 25 to 30 years. Most manufacturers guarantee their performance for a minimum of 25 years, ensuring a good return on investment over time.
Yes, solar panels can still generate electricity on cloudy days, though their efficiency may decrease. They can collect sunlight even in indirect sunlight, making them effective in various weather conditions.
While it is technically possible for a handy person to install solar panels themselves, it’s generally recommended to hire professionals. They ensure proper installation, compliance with local regulations, and safety during the process.
If your solar panels produce more electricity than you consume, the excess energy can often be sent back to the grid. Many utility companies offer a net metering program, allowing you to earn credits for the surplus energy you provide.
Solar panels require minimal maintenance. Regular cleaning and occasional inspections are usually sufficient. Some homeowners choose to invest in maintenance plans, but costs are typically low compared to traditional energy systems.
In general, solar panels will not work during a blackout unless you have a battery storage system. This system allows you to store excess energy generated during the day to use during power outages.
