What is photovoltaic (PV) technology?+
Photovoltaic technology converts sunlight directly into electricity using semiconductors.
How do PV panels work?+
PV panels are composed of solar cells that absorb photons from sunlight, creating an electrical current.
How much sunlight do PV panels need to produce electricity?+
PV panels can generate electricity even on cloudy days, but direct sunlight is most efficient.
How long do PV panels last?+
Most PV panels have a lifespan of 25-30 years, but they can continue to produce electricity for decades.
Can I sell excess electricity back to the grid?+
Do PV panels require maintenance?+
PV panels are maintenance free, but should be periodically checked for dirt or debris, and inverter performance should be monitored.
What are the benefits of adding storage batteries to a PV system?+
Batteries allow you to store excess energy for later use, providing backup power during outages and increasing self-sufficiency.
