Solar energy production

How is solar energy produced?

Producing solar energy is as easy as harnessing the sun’s rays or photons and converting them into electrical energy. This is done through solar panels composed of photovoltaic (PV) or solar cells that are installed on your roof. When the sun hits a cell, the photons are converted to electrons of direct current (DC) electricity that flow through an inverter where they are then transformed into an alternating current (AC) power. Electricity produced from solar panels is then used to power your home or business.

Solar energy produced is tracked through a net energy meter. Any unused electricity from production simultaneously goes back into the electrical grid. At night or on cloudy days – when your solar power system is not producing more than what’s needed –electricity is drawn from the grid as it normally would. In most cases, solar panels produce more than enough energy.

In order to maximize your investment and produce as much solar energy as possible, the panels need direct access to the sun’s rays for most of the day. Any shading on a solar power system will reduce its energy output considerably. Air temperatures normally do not affect solar energy systems nor do locations where there tends to be higher snow accumulations.

How much energy does a solar panel system produce?

The amount of electricity a solar panel produces is not only proportional to the sun’s intensity, but also depends on three factors: solar cell efficiency, solar panel size and the amount of sunlight directly hitting the panel. Your SolarCity energy consultant will work with you to decide how much energy you are using and map the solar installation to meet those needs.

Each solar panel should have a number listed on the back identifying how much power will be made during peak conditions, also known as a max power rating. All solar panels are rated by the DC power produced in standard test conditions. A typical solar panel produces about 200 watts of electricity based on the efficiency and size of what’s installed. For example, if you have 25 panels installed, you may have an output of about 5 kilowatts (kW).
