How does a residential solar electric system work?

Solar power is harnessed using Solar Photovoltaic (PV) technology that converts sunlight (Solar radiation) into electricity by using semiconductors. When the sun hits the semiconductor within the PV cell, electrons are freed and bus bars collect the running electrons which results in electric current.

What is a residential solar system?

For most homes, solar panels for home means rooftop solar panels – a solar array installed on your roof that generates electricity from the sun and helps you reduce your monthly spending on electricity. Solar panels save money over time on electricity costs and provide low-carbon, sustainable electricity.

Which type of solar system is best?

Among all panel types, crystalline solar panels have the highest efficiency.

  • Monocrystalline panels have an efficiency rating over 20\%.
  • PERC panels add an extra 5\% efficiency thanks to their passivation layer.
  • Polycrystalline panels hover somewhere between 15-17\%.
