"My daughter & s-i-l recently convinced me to have Doug install a whole house generator. He had already talked to my s-i-l about it when he came out to see what I needed. It was going to be tricky as I already had solar panels & didn't want to lose the credits I got from DTE for the excess power they created. After much research & learning, Doug was able to figure out how to get the generator connected so it runs automatically but my solars still work, too. Today, they finished it up & I now have backup power as well as my solar panel system helping with the electric bill. This took a LOT of extra work but he and his crew handled it as quickly & professionally as anyone could have expected. Yes, it took longer than a typical generator install but it was not a typical situation. He also had to completely upgrade my service panel which was old, outdated & a complete mess. I've had some good contractors work on my home but he & his guys are the best!! He's fair & honest & patient!"

"Andrew did an excellent job replacing my electrical panel. He was professional, knowledgeable, and took the time to explain everything clearly. The work was completed efficiently, and everything looks great. I'm very satisfied with the quality of the installation and would definitely recommend Andrew to anyone needing electrical work."

"We hired Lighthouse Electrical to install a generator interlock kit for our house and am very impressed at how smooth everything went. They were the cheapest out of 5 quotes, but didn't cut any corners. Corey came out on site for a quote which added comfort that he won't try to extra bill us once the work was to be done, and we got the install scheduled within a week from calling. Christian came out to do the install and once everything was complete he vacuumed up and walked me through how to use the switch. As a cherry on top, they didn't add a surcharge for paying by credit. I couldn't be happier with the experience."

Generator Install FAQs, answered by experts

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two.
