solar battery in Kenya vs generator

When the electricity goes out in your area, what are your options? Unless you have backup power at your home, it’s likely you’ll be sitting in the dark.

Fortunately, dozens of backup power options are available to choose from – including petrol/diesel-powered generators, and solar battery systems.

When you find the right solution for your home, you get the peace of mind that comes with knowing your household will keep running, even if the grid goes down.

Here at Jesaton Systems, we’ve helped many homeowners / businesses turn to solar and battery backup in Kenya, so we know a thing or two about the value of a good backup system.

In this post, we’ll discuss the differences between solar battery backup systems and generators and help you understand which is right for you.

Let’s dive in!

What is a Generator?

Generators and solar battery systems both provide backup power in the event of an outage. The way they do it, though, is very different.

Generators are the type of backup power systems most people are familiar with. Today, most generators run on gas, petrol or diesel.

Freestanding generators sit outside the home and either turn on manually or include sensors that detect outages and turn the generator on automatically

Compared to solar battery backup for power outages, generators are more affordable on the front end.

Despite the low upfront cost, though, generators require regular maintenance and typically come with small recurring costs. Generators typically require weekly self-tests and need continual refueling to run during outages.

They produce sound when they are running as well as exhaust that is harmful to the environment.

When a generator is maintained regularly, it can last for 10+ years.

Here are a few of the pros and cons of backup generator systems:


  • Generators are more affordable upfront than solar batteries. However, solar batteries save a household money over time and there are many rebates and incentives available that can lower the upfront cost.
  • Generators are easy to connect to existing natural gas lines.
  • Generators provide round-the-clock power, as long as they have an ample fuel supply.
  • Generators are available in a variety of sizes, from small, portable units to whole-home systems.


  • Most generators are noisy to operate.
  • Even high-end generators require annual and monthly maintenance.
  • Generators require fuel to operate, which means they are not eco-friendly.
  • Fuel left too long in a generator can go stale, causing problems with the equipment and additional repair costs.
  • Generators create emissions during operation, creating an unpleasant smell and a high carbon footprint.

What is a Solar Battery Backup?

Solar battery backup systems run on electricity and are charged by a connection to the home’s solar energy system.

The batteries store excess energy produced by solar panels and save it for later use.

Some of the most common types of battery backups available today include:

Solar battery storage systems are popular because they are reliable.

When the grid goes down, a solar-powered battery backup system will draw stored energy from the batteries to power your home with no interruptions or downtime.

In addition to providing unparalleled reliability, battery backup systems are cleaner and quieter than generators and are also a more environmentally-friendly option.


  • Battery backup systems operate almost silently.
  • When combined with solar, battery backup systems run entirely on renewable energy, which means you don’t have to spend money on dirty, expensive fuels.
  • Battery backup systems increase your home’s daily solar consumption.
  • Installing a battery backup system can increase the value of your home.
  • Battery backup systems offer low maintenance requirements and a long lifespan.
  • These systems operate seamlessly during grid outages.


  • Higher upfront cost.
  • Systems have limited power capacity.

Buy a Standby Backup Generator if…

A standby backup generator is an ideal solution if you don’t mind the noise and maintenance required, you only want a system that can provide emergency power, and you have no intention of installing solar panels in the future.

If your home has an existing natural gas line, installing a standby generator may be relatively straightforward.

Buy Solar Battery Backup if…

Solar battery backup is an excellent option for customers who want a backup system that can work with an existing or future solar energy system.

A battery system is right for those who prefer a quiet, low-maintenance, reliable, and environmentally-friendly solution.

Consider investing in a battery backup system if you want to keep the lights on and power essential home appliances during a grid outage and also reduce peak electricity charges.
