"Very well. These guys, Gil, Luis, Jake and Nick, did a great job with our 2 day installation, they were professional, friendly, answered questions easily, protected the indoor environment (drop cloth, ppe etc), and reassembled and thoroughly cleaned everything afterward. Look forward to contracting with them again for any other large job."

"I can’t recommend Botelho and Sons Electric highly enough. From start to finish, the experience was outstanding. They were punctual, neat, and completely reliable, showing up exactly when they said they would and keeping the work area clean and organized throughout the entire project. I had a 200-amp panel upgrade, lines run to a pool & hot tub, copper wire installed for the pool and the connection for our generator - everything was done to code, with obvious skill and attention to detail. Out of 6 electricians I got quotes from, Ryan offered the best price without cutting any corners. On top of that, both he and his employee were incredibly knowledgeable and professional. Bonus points for being amazing with my 130 lb Cane Corso, who is usually suspicious of strangers. It was clear they were comfortable around dogs and respectful of my space, which made the whole process that much smoother. If you want high-quality work from someone you can trust, I wouldn’t look any further!"

Generator Install questions, answered by experts

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

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. 

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

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.
