FAQs

WHAT ARE PHOTOVOLTAICS AND HOW DO THEY FUNCTION?
Photovoltaics, or solar panels, are systems that convert sunlight into electricity. They operate by utilizing photovoltaic cells, typically made of silicon, to convert sunlight (photons) into electrical current (direct current). This conversion process occurs through the excitation of electrons within the silicon cells, generating electricity. The direct current is then converted to alternating current (AC) using an inverter, making it compatible with household appliances and the electrical grid. This systemic approach allows for the capture and utilization of a renewable energy resource, promoting sustainability and reducing dependence on fossil fuels.

WHAT ARE THE ENVIRONMENTAL BENEFITS OF USING PHOTOVOLTAICS?
The environmental benefits of photovoltaics are substantial. By converting sunlight into electricity, solar panels produce energy with minimal to no negative impacts on air quality or greenhouse gas emissions. This transition to solar energy helps reduce overall carbon footprints, contributing to efforts against climate change and environmental degradation.
