"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!"

"Contacted S&S via Angies List to get a quote on some electrical work. Scott and his team were very responsive and helpful. It turns out that I did not use S&S for this work at this time, but I wanted to comment favorably on their customer service. Would consider them for future work and recommend others consider them."

"David did an amazing job. He called me very quickly after I signed up on Angi. He set up a time to do the job within 4 days. He got both jobs done in a very short amount of time. His price was really reasonable. I would not hesitate to hire David again!"

Generator Install questions, answered by experts

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

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 determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
