How do solar panels work?

Solar panels convert sunlight into electricity using photovoltaic (PV) cells. Sunlight hitting the cells produces direct current (DC) electricity, which is converted to alternating current (AC) by an inverter to power your home or office.

How long do solar panels last?

Most solar panels are warranted for 25 years and operate efficiently for 25–30 years or more. They gradually lose efficiency but remain a reliable source of power for decades.

What are my savings if I install solar panels?

Savings depend on location, usage, and system size. Homeowners typically save 50%–100% on electricity bills, which can add up to tens of thousands of dollars over 25 years.

What maintenance do solar panels require?

Solar panels need little maintenance — mainly occasional cleaning to remove dust/debris and system checks. Most systems also include monitoring tools to track performance.
