Grid-Tied Solar vs. Off-Grid Solar: What are the pros and cons of both?

March 16, 2018

When purchasing a solar system, you have two main options to choose from – grid-tied and off-grid. In order to pick the right type of system, it’s important to list the goals you’re hoping to achieve by adding solar energy. Here at Paradise Energy Solutions, we only sell grid-tied solar systems, but we realize it’s important to consider the pros and cons of both grid-tied solar and off-grid solar, so you can identify the system that best meets your goals.

Grid-tied Solar Systems

A grid-tied solar system is connected to the electrical grid and requires the grid to be running for the solar system to produce energy.

Pros of a Grid-Tied Solar System:

  • Grid-tied systems tend to be the less expensive option, due to not needing batteries and other equipment
  • This type of system is great for those who don’t have the room or financing to install a solar system big enough to cover 100% of their energy usage. You can continue to pull electricity from the grid if needed
  • Net Metering allows the electricity generated by a solar system to offset the electricity used from the grid during the night or cloudy days
  • The grid becomes your cost-effective, reliable storage solution
  • In some regions, Solar Renewable Energy Credits (SRECs) allow owners of a grid-tied system to receive extra income by selling the SRECs their system produces

Cons of a Grid-Tied Solar System:

  • If the grid goes down your system will shut off, leaving you without power. This is required to prevent energy from back feeding into the grid to keep utility workers safe.  Your grid-tied system will automatically shut off when the grid goes down, and will also automatically turn back on when power is restored
  • You’re not completely independent from the grid

Off-Grid Solar System

An off-grid solar system is completely independent from the grid. Batteries and other equipment are required for the system to function.

Pros of a Off-Grid Solar System:

  • Completely independent from the grid
  • A great solution for remote locations and underdeveloped communities

Cons of a Off-Grid Solar System:

  • They are more costly
  • Batteries are required to deliver electricity consistently throughout the day and night
  • It could require a lifestyle change to reduce energy consumption
  • Surplus energy production could go to waste
  • Cannot rely on the grid at night or on cloudy days
  • Batteries require maintenance, have a relatively short lifespan, and degrade rapidly
