Solar Home Diagram

While solar power has been around for decades, it has become far more efficient in recent years. The technology keeps advancing, so the panels you can fit on your roof generate even more electricity. And as the use of solar expands quickly worldwide, the cost of the equipment continues to fall.

Here’s how solar power works:

1

Solar “photovoltaic” or PV panels convert sunlight to electricity. Sunlight causes the electrons in the panels’ silicon cells to release energy that becomes direct current (DC) electricity. The more panels you can install, the more power you will generate.

2

An inverter is a small device we install in your home that converts the DC power into AC or alternating current – the kind of power we use in our homes.

3

Your house uses the electricity you produce, reducing your dependence on power from your utility company. Your house remains connected to the grid, and power flows to and from your house automatically. If you produce more power than you need, you push power back to the grid. If you need more power than you are producing, then your house pulls electricity from the grid. Solar battery options are available to store the power you generate at your home, but they remain costly.

4

We install a monitoring system that allows you to watch your power generation in real time – even from your cell phone. The electric meter on the side of your house will actually go backwards when you are pushing power out to the grid!

In addition to the money you save directly by generating your own power, you can also sell the excess power you push back to the grid. With Solar Energy World, if you purchase your solar system, then you own the Solar Renewable Energy Credits (SRECs) you generate. This is the system used to track and sell power on the open market. This system is automated so there is nothing for you to do but collect payments when you generate excess electricity. Click to learn more about how SRECs work.
