  • What Is A Solar Generator For A House?

    BougeRV portable generator powering a laptop

    A solar generator collects infrared energy from sunlight and converts it to power that is stored in a rechargeable battery pack. Many new homes being built today include solar power systems that are capable of completely offsetting the demand the home puts on the grid. 

    These are large and expensive systems that require professional installation and electrical work and should not be attempted by the DIYer. When the power goes out, these systems are offline, too. A whole home solar system does not function as a backup system. 

    A portable solar power generator with the capacity to keep appliances you need operating when the power is out can make power outages easier to handle. Portable solar generators have limits that can restrict which appliances you run and for how long. Picking the right one means you will need to decide what you want to power with it and for how long you will need power. 

    Can Solar Generators Run The Whole House?

    In theory, a solar generator can power an entire home, depending on the battery capacity, solar power panel efficiency, and the rate at which the generator can recharge.

    In practice, portable generators are simply too small to run everything in your home, and may only be able to run certain appliances for a short time. The higher the power demands of your home, the more capacity you will need from the battery backup. 

    What Size Generator Do I Need For My House?

    People buy battery backup generators for a lot of reasons. We sell quite a few that are destined to be used in RVs headed off the grid for days at a time and a number of our products are used by emergency crews and search-and-rescue teams to provide emergency power. 

    Increasingly, our customers are contacting us asking about whole-home backup solutions. Let’s discuss some realities and then we will show you how BougeRV.com can help you overcome limits to powering your home with portable solar generators. 

    What Do You Actually Need To Power?

    Blackouts can happen for many reasons. In places like California and Texas where the temperature often exceeds 110 degrees, power failures happen because of an overloaded grid, but it is rarely out for more than a few hours. 

    In the mid-west, tornado damage can cut power to entire communities, sometimes for days or even weeks. Areas of the country exposed to natural disasters like wildfires and hurricanes may be without power for months at a time. 

    Depending on the situation, you will want to have an appropriate backup in place. Short interruptions in power can be solved easily with lower-wattage generators and basic solar panels. Long-term power outage situations may require larger battery backups, more numerous and high-quality solar panels, or the use of multiple generators to supply the power you need. 

    The other part is powering devices you might need versus things you simply want. For example, powering an air conditioning unit or a refrigerator is going to require a lot of power and a substantial solar array to keep the battery charged. Charging a cell phone or powering an internet modem requires much less energy.

    Figuring Out How Much Power I Need

    BougeRV energy calculator for home appliances

    We have an easy-to-use energy calculator tool that can make it much easier to estimate the amount of energy you will need to power an appliance. The wattage calculator will add up the total amount of power you will require based on the average appliance values. 

    Or, you can go to EnergyElephant.org to work out your energy need. You will also find an extensive chart on the site detailing specific appliances and common power requirements. 

    Keep in mind that appliances become less efficient as they age and will require more power than newer models. 

    Choosing The Right Generator: The Basics

    Lots of customers come to us searching for the perfect solar power battery backup solution for their home or recreational vehicle. That’s because we are the experts in the field, and our reputation for providing durable and high-quality power solutions is legendary. What we find most often is that people don’t have a good idea of how much power they need, making it impossible to determine what solar generator will work. 

    Unfortunately, many people shop based on price rather than functionality, only to realize that when they need the generator, it isn’t powerful enough. To make matters worse, many internet sources will tell you unhelpful things like; “a house needs 5,000 to 7,500 watts to run,” which may be true, but no two houses are alike and there is a lot more that goes into choosing the right product than total wattage.

    Determining the right solution for your home can require a substantial amount of math, so we put together some helpful guides that will make understanding the amount of power you require much more simple. We will also share the formula you’ll need to figure out exactly what appliances you can power and for how long. 

    First, we want to briefly explain some of the terms used to describe the capabilities of solar power backup generators before we start talking about how to pick the right portable battery backup product for your needs.  

    Common Appliances And Whether A Solar Generator Will Work

    There are a few terms that are used when discussing appliances and how to power them with generators. The most important ones are: Starting Wattage, Running Wattage, and Volt/Amps to Watts. 

    • Starting Wattage: This number refers to the number of watts required to start an appliance. Appliances like light bulbs and space heaters are passive and appliances such as dishwashers and blenders are active wattage users. This means that some appliances will require much more power to start than they require to run. 

    • Running Wattage: All appliances require some amount of wattage to run continuously. Generally, active appliances require more power to start than they do to run, while passive appliances use the same amount of wattage to run as they do to start. 

    • Volts/Amps to Watts: A general way to get a rough estimate of the power demands of an appliance is to divide the available volts by the required amps. This will give you the wattage of the appliance. 

    This is only an estimate and is typically on the high side of actual wattage requirements, but specialized equipment and complex math is needed to determine actual wattage versus estimated wattage. Most appliances provide the watts and amps information on a tag that includes the make and model number as well as the serial number of the appliance.

    Factors That Impact Runtime

    The above numbers are under ideal conditions. You can clearly see how a portable generator could quickly become overwhelmed trying to power many common appliances. 

    Other factors can lead to even shorter runtimes. For example, the number of people in your household using power at any one time, the age and condition of appliances, and the efficiency of the power generator all make a difference.
