Yes, solar panels can still generate electricity on cloudy days, although the efficiency is reduced. Even diffused sunlight can be captured by photovoltaic cells, leading to around 25% of their maximum output. So, while you won't get the full potential, you can still enjoy some clean energy production even when the sun isn't shining brightly.

Solar panels are built to withstand harsh weather conditions and have a long lifespan. Most panels come with a 25-year performance warranty, guaranteeing at least 80% of their initial power output during that period. In reality, they often continue to generate electricity for several years beyond the warranty. So, investing in solar panels is a long-term decision that can provide clean energy and cost savings for decades.

The amount you can save by going solar depends on several factors, including your current electricity usage, local electricity rates, and the size of your solar system. However, in many cases, homeowners can save thousands of dollars on their electricity bills over the lifetime of their panels.
