How Solar Power Works

Day to day, light hits your roof’s solar panels with particles of sunlight. The solar panel transfigures those photons into electrons of direct current (DC) electricity. The electrons stream out of the solar panel, going into an inverter and other electrical safety apparatuses. The inverter changes that DC power (generally used in batteries) into alternating current or AC power. AC power is the electricity that your TV and other home appliances use when they are plugged into the wall socket.

Solar Cells

Solar cells are tiny, square-shaped panel semiconductors produced from silicon and other conductive materials, made in slim film layers. When sunlight comes in contact with a solar cell, chemical reactions discharge electrons, spawning electric current. Solar cells are known as photovoltaic cells or “PV cells” too and could be found on several minor appliances (for example, calculators).

Components of a Solar Photovoltaic (PV) System
The Beginner’s Guide to Installations

Includeded in a PV system are PV modules or a bunch of PV cells generally referred to as PV panels; at least one battery; a charge regulator/controller for a stand-alone system; mounting hardware or a framework; an inverter for DC to AC solar power conversion of the system connected to the utility grid; and wiring. A PV module organizes singular PV cells, and the modules are gathered together in one array. Arrays are sometimes set on unique tracking devices to follow sunlight all through the day and boost system efficiency.

PV System Installation

It’s possible to install a photovoltaic (PV) or solar electric system on your own. However, to avert problems or injury, you should hire a well-reputed professional contractor who is experienced and provides a system warranty of 10 years at least.


Though they are high-level electric systems, PV systems have few moving parts, so they need not much maintenance. The basic PV module comes with absolutely no moving parts and can survive more than three decades years while calling for little maintenance.


The components are designed according to very high reliability and dependability standards. Installation and maintenance of a PV system is best done by a professional.

Sunlight Requirements

A photovoltaic (PV) system requires unhindered access to the sun’s rays for a good part of the day in order to be effective. Shading on the system can usually decreases energy output extensively. Climate is not a main concern, considering PV systems are normally unaffected by air temperatures, and snow cover generally melts fast, with the panels directly facing the sunlight.

Solar PV System Size

Numerous factors dictate the right size of your solar system, like the size of your roof, your power consumption, your budget, the amount of energy you want to produce, and the rest. A system designer or installer can give you expert recommendation as to the type of system that suits your needs.
