5 Faqs About Whole House Solar Generator

There are times in life when it feels like spending more than planned. In-home power supply, the whole house solar generator can save money and have obvious effects. The best part about that whole house solar generator is that not only are they less reliant on fossil fuels, but they don’t require much maintenance beyond the refill time that takes place every few months.

Power outages are seriously inconvenient and often dangerous. They can damage or completely ruin electrical systems and appliances, and you may be in hot water if critical systems are without a power source. Most homes rely heavily on electricity for all sorts of things. Grid power, although often reliable, goes down when it’s least convenient (it’s never convenient!) leaving you with zero electricity.

Power outages often come from stressing the power grid; particularly hot stretches of time (hello… global warming), natural disasters, or serious storms are all common causes for power outages. Outright negligence and poorly maintained grid equipment from utility companies is another increasingly common reason.

One way to prepare yourself for the inevitable power outages is to invest in a whole house backup generator, and while you’re researching options, it’s a good time to learn about solar-powered generators. 

Solar-powered generators are power sources that convert sunlight into electrical power by means of a solar panel. They work similarly to a rooftop solar system but aren’t made for extended periods, and many, but not all, are paired with batteries so you can store electricity for later consumption (that last part was important).

Solar-powered generators act similarly to conventional generators but aren’t reliant on a fuel source other than the sun. For ultimate flexibility, many generators have multiple methods of charging, whether through a wall outlet, car plug, or solar panels. This degree of flexibility may be ideal for rolling with the blackouts.

Making the switch to a solar power generator will not only help you be more independent and flexible when it comes to backup electricity needs but also pay less in energy costs, have a less noisy system, and is environmentally friendly.

Before you choose to get your own solar generator, it’s important to determine how much power you need, what the needed storage capacity should be, and which battery type is ideal for your situation.

This article will cover much of the information needed for setting up a solar power system and a home solar backup generator for everyday needs.

1. Can a solar generator power a whole house?

Find a solar generator with enough capacity to meet your needs. These portable powerhouses are rated between 200 watts to 3,000 watts. These solar generators are very convenient and effortless to set up.

However, to run the whole house solar generator you need to select the right size with a battery capacity big enough so that you can run your appliances for desirable backup time.

 The wattage of this solar generator can be considered above 1000. Combined with the portability of solar generators, it can be used for electric lights in the house, mini stereos, or emergency power outages for families. Analyze the characteristics of solar generators’ performance.

2. What size solar generator do you need to run a house?

The most important thing is to pay attention to which devices in the house you need to power. The power of the power supply equipment is defined, so solar generators that can carry this equipment are selected.

As per  EIA in 2020, the average power consumption of a residential utility customer in the US is 900kWh per month. Accordingly, for a day the average power consumption of a residential customer is 30kWh. Likewise per hour, the same will be roughly 1.25 kWh. Furthermore, 1.25 kWh is equal to running a 1.25 kW load for one hour. Therefore, this implies that the minimum rating of a solar generator needed to run a house should be 2,000 kW with a battery backup of at least 2,000 Wh.

As a general rule, the generator should be around 2 times the size of the inverter’s continuous output. For example, a 4,000-watt inverter should be paired with an 8,000-watt generator.

This is because the generator needs to charge batteries while still powering the loads (appliances using energy). If the loads total 4,000 watts, and the charger is 60 amps at 48 volts that totals around 7kW of continuous power: 60a x 48v = 2,880 watts + 4,000 watts = 6,880 watts.

8kW would make sense as a minimum generator size to power the loads and have enough power to charge the battery bank as well.

It’s a good idea to round up slightly to give some headroom for the generator, especially at higher elevations where your generator is going to lose some of its power. Engines can lose around 3% of their power for every 1,000’ increase in altitude. Make sure you account for this if your system will be installed at a high elevation.

3. How many solar panels do you need to power a whole house?

We estimate that a typical home needs between 20 and 24 solar panels to cover 100 percent of its electricity usage. The actual formula to find out how many solar panels you need can be found by the system size divided by the production ratio, divided by panel wattage. 

Calculating how many solar panels you need can be done with the three inputs above, but digging deeper, there are many more factors at play in determining your ideal solar panel system size. Understanding production ratios, the relationship between system size and the number of panels, and the impact of home size can all be important when you’re designing your ideal solar panel setup.

4. Is it worth getting a solar generator?

Solar generators consist of solar panels and portable power stations to capture energy from the sun and store it for later use. You can use one as a source of on-the-go power, as a backup source of energy for your home, or as both.

After the up-front cost of the equipment, solar generators have no additional running expenses compared to gasoline-powered generators. They provide an unlimited energy source from direct sunlight, so there is no need to buy fuel. They also have no moving parts, meaning fewer maintenance costs.

5. How much does a whole house solar generator cost?

The cost of a whole house solar generator for a battery capacity of 2,000 Wh to 5,000 Wh without solar panels varies from $2,100 to $5,400. Moreover with portable solar panels, the same will cost you from $4,200 to $7,200 and with conventional solar panels, the same will cost you between $3,300 to $6,600.

Final thought: When you hear outside noises, there are irritable, anxious impulses. As a result, on a sunny day, you always remember that there is light energy that can provide energy for the family and carry on the day. In the event of weather like power outages, snow, and cloudy conditions, the whole house solar generator that saves energy comes into play.
