Yes. While the upfront cost may vary, solar systems drastically reduce monthly electricity bills and often pay for themselves within 5–7 years. Many countries also offer incentives, tax credits, or feed-in tariffs to further enhance savings.

Most solar panels are designed to last 25 to 30 years. Even after that, they continue to produce electricity at around 80% of their original efficiency, making them a long-term investment.

Not necessarily. Batteries are optional and allow you to store excess energy for later use or during power outages. Without batteries, your system can still function by exporting excess power to the grid.

Yes. With the right system size and design, solar panels can supply 100% of your energy needs, depending on location, usage patterns, and sunlight exposure.
