Solar cells are the fundamental component of a photovoltaic installation. The solar cells are connected by wiring, and then assembled into panels. Panel installation not only requires mounting the panels on the roof, but connecting them to each other as well. Inverters are the part of a photovoltaic installation that is not located on the roof. Instead, inverters are placed on a wall, typically near structure’s electric meter.
Panel installation by solar professionals
The process of a photovoltaic installation begins with a home evaluation, conducted by a professional solar installer. Installing photovoltaic systems requires a thorough analysis of the orientation of the roof to the sun, an examination of the roof’s strength and size, and an extensive evaluation of the structure’s current electrical usage. The collected data helps determine the best size and type of the panel installation for the photovoltaic installation.
The photovoltaic installation itself typically begins with the panel installation. The panels are mounted to the structure of the roof itself, not the roof covering. Wiring from each panel is gathered in a covered cable that leads to the inverter. Planning for the photovoltaic installation takes more time than the installation itself, which usually takes only a few days.
A photovoltaic installation is best undertaken by a professional. Certified photovoltaic installation professionals will ensure that while installing photovoltaic systems, everything is performed according to building codes and that the systems will pass inspections. Installing photovoltaic systems requires a thorough understanding of electrical systems, as well as knowledge of roof construction.
