Residential Solar Installation

While installation may look different from state to state, Intermountain Wind and Solar generally follows a six-step process for installing solar panels:

  1. An at-home consultation
  2. A custom system design
  3. A review of your financing options
  4. The filing of proper permits and paperwork
  5. Installation from certified professionals
  6. Post-installation repairs and maintenance

Intermountain Wind and Solar offers customers an online application that estimates their energy savings and helps them ensure their panel output aligns with its estimated efficiency.

Commercial Solar Installation

Intermountain Wind and Solar has built solar panel systems for a variety of businesses to help them improve their bottom line. IWS urges businesses to consider going solar and cites three top reasons for switching to the renewable energy source:

  1. Tax incentives reduce the overall cost—There’s a current federal tax incentive for solar that allows you to deduct 30% of the cost of installing solar panels.
  2. Solar is a safe investment—IWS predicts that commercial customers will receive a return between 10%–15% per year over the life of their solar system.
  3. Solar frees up expenses—Intermountain Wind and Solar estimates that companies will receive $1.50 for every $1.00 spent on solar.

Battery Back-Up

IWS offers the Tesla Powerwall battery back-up for customers who want to store their solar system’s excess energy. The solar battery gives homeowners and businesses on-demand solar energy for unexpected events like power outages.

The battery comes with a mobile app for system monitoring, so you can keep track of battery storage levels, peak levels of home energy usage, and power outages.

Frequently Asked Questions About Intermountain Wind and Solar

Do I have to go off the electrical grid when I switch to solar?

No. Most solar energy systems are connected to the grid during installation, so any excess energy your system produces goes back to your utility company. Your utility company will award credits toward your electric bill based on the amount of energy the grid receives, a practice known as net metering.

Are solar panels difficult to maintain?

Solar panels don’t have moving parts that break easily and don’t require much maintenance. Annual cleaning with water and soap should be enough to keep your panels operational.

When will I need to replace my solar panels?

Most solar panels see a significant power output decrease within 25 years, but solar panels typically come with a manufacturer’s warranty of around 20 years.
