Off-Grid vs. Grid-Tied Home Solar Systems

When someone mentions living “off the grid,” what do you picture? Most people see a remote location with a small, ultra-efficient house and no one else around for miles. For many years, this was exactly how off-grid home solar systems were used: as a way to generate power for those who lived in an area where no power lines existed.

As the world’s population grows, however, it’s increasingly hard to find a place to live where power lines haven’t already been installed. Additionally, there are millions of people living in cities around the world that want to experiment with off-grid living without moving out of the urban areas they know and love.

Luckily, it is still possible to generate your own electricity whether you live in the middle of town or the middle of nowhere. To decide which is better for you, it’s essential to know the difference between off-grid and grid-tied home solar systems. Each has its own benefits and challenges, but both will help reduce your energy costs and improve the environment.

In either case, though, there are several important things to note regarding solar power today:

Now, on to off-grid and grid-tied home solar systems:

Off-Grid Home Solar Systems

Off-grid solar systems means that you are 100 percent reliant on the power generated by your own solar panels.

  • Advantages of an off-grid solar include lack of electricity bills, freedom from rate hikes, and the knowledge that you’ll be able to enjoy power in most emergency situations.
  • Disadvantages of an off-grid solar system include the need for large battery storage banks, a lack of power if there’s no sun for more than a few days, and no emergency power if inclement weather were to damage or destroy your system. Energy storage products range a great deal in price, design, etc., but the Tesla Powerwall has risen to the top of the market in terms of attention and seemingly price. Though, you should definitely explore the home battery market extensively before making a conclusion regarding cost and purchasing a product.

Grid-Tied Home Solar Systems

A grid-tied home solar system means that solar power is your default power source, but the home is still connected to a municipal power supply.

  • Advantages of a grid-tied solar system include the flexibility that comes from having a secure source of backup power. Excess power generated by home solar system can be fed back into the grid, and net metering can actually turn your meter backwards, earning you profit from the power company. If, during an emergency or inclement weather, you need to draw on grid-based electricity, the cost is lowered as a result or may even be free.
  • The main disadvantage of a grid-tied system is the need to live close to power transmission lines.
