What is a Solar Energy System?

A solar energy system is what converts sunlight into electricity that we can use. This is done by collecting light from a roof or ground mount solar panels that create direct current (DC) electricity.

In a solar energy system, an inverter is required to convert the electricity to alternating current (AC) electricity, which is the type of electricity used on the grid. AC electricity allows the electric charge to flow through different directions and be used directly in the home or business.

Our high-quality intelligently designed solar panels are built to last – if you’re looking at reducing long-term energy costs and installing a solar energy system, contact our local solar installers at or click here to request a quote.

What are the three types of solar energy?

When consulting with your solar installation company, talk about the different options available and what your space is best suited for There are three types of solar power systems: grid-tied, grid-tied with battery backup, and off-grid.

Grid-Tied Solar Energy Systems

A grid-tied system is best for those who already have utility service – it connects the solar energy system with a traditional utility grid. This type of system is the least expensive to install, especially since if the solar panels produce more than consuming, it can be sold back to the utility company through net metering.

Grid-Tied Solar Energy Systems with Battery Backup

In areas prone to power outages, a grid-tied system with a battery backup is a great option. The backup batteries allow your solar energy system to store excess energy to use in the event of outages, low energy production, or high power consumption.

Off-Grid Solar Energy Systems

For off-grid solar energy systems, you are entirely independent of the traditional energy company. Batteries are essential since they must make all the electricity necessary to power your building.

How do home solar energy systems work?

Solar panels work because they are composed of photovoltaic cells (PV) cells that absorb sunlight. When the light hits these cells, electrons in the panels come loose, creating an electricity flow. To power a home, electricity must be converted from direct current (DC) to alternating current (AC) through an inverter.

From there, the energy can be used within the home or sold back to the grid.

How many solar panels are needed to power a house?

In the last few years, the cost of quality solar installations has gone down due to advancements in technology and more people deciding to go solar. When asked how many solar panels are needed to power a house, the honest answer is that it depends on the everyday energy needs, location, roof size and if it is going to be a grid-tied or off-grid system.

Our local energy installers can provide an accurate assessment of your home’s solar energy potential and what to do to maximize savings.
