How to Choose The Best Whole House Solar Generator?

Whole house solar generators are becoming the go-to solution for the ever-increasing power outages sweeping across America.

According to PowerOutage.US, utility customers experienced 1.33 billion outage hours in 2020, up 73% from roughly 770 million in 2019.
With extreme weather occurring more frequently, that number is only set to increase going into 2022.

One way homeowners can ensure they are protected from any outages is to equip their home with a solar system, generator, or solar generator.

Solar systems are expensive, and not everyone can afford them. Generators, although a viable solution, are noisy and unsustainable.

On the other hand, whole home solar generators check all the boxes. More affordable, has no noise, and is much more sustainable.

In this article, we will explain why you should look into purchasing a whole house solar generator kit and how to choose one and four of the most recommended kits available.

Why should I get a whole house solar kit?

1. Solar generators run silently and emit no fumes

As you may be well aware, solar generators do not emit any toxic fumes and are almost completely silent. 

They emit no fumes as they do not burn any fuel in order to operate (such as gas-powered generators). 

Additionally, they are silent. They emit less than 60dB (while the inverter fan is running) other than that. They make no sound. For context, a whisper is 30dB and a human conversation is about 60dB. 

2. Solar energy is a renewable clean energy source

One of the most important aspects to focus on, sustainability. Solar generators essentially recharge themselves via the power of the sun. 

This means you do not need any grid connection in order to power your appliances. As long as there is sun, you are pretty much good to go. 

3. UPS

Most residential solar backup systems are designed to kick on as soon as the utility power fails and to shut off when utility power is restored automatically. in other words, you will have uninterrupted power supply (UPS).

4. Sufficient power supply

A whole house solar generator allows you to cover all of your home’s electricity needs at once, even if you have a high electrical demand (for example, if you live in a larger home or need more than an emergency system for medical equipment).

5. Low maintenance

With solar backup generators and power stations, minimal maintenance is needed to keep your system running well—just make sure it’s charged with plenty of sunshine!

6. Flexibility

Many battery-based storage systems can also integrate with additional batteries or add-on products to create a customised solution for your unique home energy needs—including adding storage capacity via an additional battery.

How to choose the best whole house solar generator?

Choosing a solar generator really all comes down to what your electrical needs are. How many appliances do you want to power, and for how long? 

We will get to that in a second. 

With regards to the actual product. You want to make sure that the brand you decide on is using the latest technology. The reason for this is simple: LCOS - Levelised cost of storage.

Do not be swayed by brands offering extremely cheap solar generators. It is not the price tag that counts, it is the LCOS. 

The LCOS is the cost of kWh (or MWh) electricity discharged from a storage device when accounting for all cost incurred and energy produced throughout the lifetime of the device.

For example, if you come across a really cheap solar generator it is almost guaranteed that the product is made from inferior technology, such as with a lead-acid battery. 

The upfront cost might be lower, but you will find yourself having to pay much more in the long run as these devices do not last nearly as long as something with the latest technology. 

So, rule of thumb. Go for the solar generator with the lowest LCOS. 

See the below example: 

Here's an example table below: 

  Lithium-ion 12V, 100Ah Lead-acid 12V, 100Ah
Upfront cost 739.99 USD 174.99 USD
Depth of discharge 80% 50%
Total number of cycles (10 years) – 3600 cycles (2 years) – 700 cycles
Total kWh over lifetime 3’456 kWh 420 kWh
LCOS 0.214 USD/kWh 0.417 USD/kWh

 

See how much cheaper the 2nd option looked at first? But look at that major difference in LCOS. The lithium battery is in fact 2 times cheaper over the long run. 

Once you have got LCOS out the way, you'll want to consider the capacity. Essentially, the more power hungry appliances you want to power, the higher capacity solar generator you'll need. 

Pay attention to the total capacity your solar generator of choice is rated at. This is usually measured in watt hours (Wh).
