Energy Select is a full-service energy consultant and contractor. Our main focus is solar panel installation. We specialize in looking at the whole picture to provide the best energy solution with a balanced effort of energy conservation and clean energy production. We will look into each customer's needs and situation in order to evaluate the best solution, even if it is not going solar! Unfortunately, we do NOT provide solar panel repair.

"Recently purchased a solar energy system for the house (75% offset). From start to finish, the entire process was enjoyable with all the staff from Energy Select; Karen, who gave me a myriad of options and answered all my questions to help me make a well-researched investment that I know will pay off in years to come. Zach helped with the engineering and provided options for install locations with minimal impact on the home or its appearance. Will who assisted with the post-install inspections and permitting process was available and worked around our schedules to make sure we got the certification to operate, as well as explained the process and expectations. The install crew was very professional and gave an explanation of what they would be doing and placed the supplies in a way to not impact our day-to-day. Tamika with operations was helpful with updates on the multiple stages of the project as well as any questions I had during the process. Again, the entire staff at this company was phenomenal with the professionalism and experience they provided during the process. The system has only been on a few days, it's exciting to see how well it works even with the cloudy weather. If you are looking for a company to go on the solar journey, look no further than Energy Select, cannot recommend them enough."

Generator Install questions, answered by experts

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.
