"Vitality arrived within an hour of contacting Firefly electric for an estimate to install an extra outlet in my home. We had 2 other estimates and Vitaliy was by far the most reasonably priced. He was able to install it on the spot and did a great job. I would highly recommend Firefly electric and will be using them for all my future electrical needs."

"Can highly recommend this company. Service and installation was great. Very professional and friendly. Generators are in short supply, so plan early. Allow about three to four months for generator to be available."

"I guess the price alright. It's about what we paid in Charlotte with another company, maybe just a tiny bit less. But I guess it's the what the prevailing rate is. We had somebody else to do the work, and they didn't do; and we paid them more. We have signed up to use them for our maintenance service for the furnace and air conditioner."

"Key is very polite and professional. He was able to handle my issue quickly. Key noticed a faulty wire (not what he was here for), which is not the first time that’s happened in this house. He fixed it when he could have just left it. I appreciate his attention to detail. If it was possible to give him more than 5 stars, I would."

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

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

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.
