Frequently Asked Questions (FAQs)
What size solar system do I need?
The size of the solar system you need depends on your energy consumption, roof orientation, and shading. A professional solar installer can conduct a site assessment and provide a personalized recommendation. Generally, you need to analyze your past utility bills and determine your average daily energy usage in kilowatt-hours (kWh). Then, you can calculate the required solar panel wattage based on the available sunlight in your area.
How much does it cost to set up a solar system?
The cost varies depending on the system size, components, and installation method. However, government incentives and financing options can help reduce the overall cost. Costs can range from $15,000 to $35,000 for a typical residential system, but these costs are often offset by tax credits, rebates, and long-term savings on electricity bills.
How long will my solar panels last?
Most solar panels come with a 25-year performance warranty, but they can often last much longer. With proper maintenance, solar panels can continue generating electricity for 30 years or more. Performance will slowly degrade over time, but the degradation rate is typically low.
What happens on cloudy days or at night?
On cloudy days, solar panels still generate electricity, but at a reduced rate. At night, they don’t produce any electricity. If you have a grid-tied system, you can draw power from the grid when your solar panels aren’t generating enough electricity. If you have an off-grid system, you’ll need battery storage to power your home at night or on cloudy days.
Do I need batteries for my solar system?
Batteries are typically only needed for off-grid or hybrid systems. Grid-tied systems can rely on the utility grid for backup power. If you want to achieve energy independence or store excess solar energy for later use, batteries are a good option.
