Your Home Solar specializes in clean energy and energy storage systems. However, we seek to be more than just a solar company. We serve our community while bettering the lives of our customers every day. We are veteran owned and operated and we pride ourselves in providing a top-quality installation with a competitive price while offering responsive support if it's ever needed for your system in the years down the road. We are passionate about solar energy and want to be part of the solution while we help contribute to making this world a better place. We truly believe that not only can solar help get us there, but it also makes financial sense to be more energy independent from the grid, lock in your energy costs now, and gain the peace of mind of backing up your home's power in the case of grid outages. At Your Home Solar, we always treat your home like it is our home.

"Everyone from the start of working with this company was great. We had solar panels installed back in 2022 and the company then they went under federal control. I had called multiple companies, no one was willing to help except your home solar. We needed a permit to get the solar up and running which also meant the state inspection. Anita, Landon and all of the other employees that we encountered in this process made it a very easy process. I would recommend this company to anyone looking for solar or that needs to get panels they have up and running. "

Generator Install questions, answered by experts

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

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.

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.

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.
