Using solar energy: Do I still need battery storage?

use solar energy is smart and forward-looking. As innovative as the technology is, it raises a number of interesting questions. If you are wondering whether you need a generator in addition to solar panels, you will find answers in this article. 

One thing is certain: Solar modules themselves do not provide an emergency power supply. Why? Well, all grid-tied solar systems shut down immediately once the grid stops supplying energy. We'll get to the reasons later. 

In order to maintain the power supply even during a power failure, you must integrate a solar cell storage system or an emergency power generator into the solar system.

Before we get started, let's take a look at the difference between generators and storage.

Generator vs. storage: differences at a glance

It doesn't matter whether you decide on a mobile or stationary electricity supplier - at the beginning there is the question of whether you are sustainable use solar energy would like.

In this direct comparison, we look at 3 generators:

• Portable Power station with solar panel
• Portable generator with internal combustion engine
• Stationary diesel generator

This table shows that both generators and solar storage have advantages and disadvantages. But how do you determine which energy source suits you best? 

Ideally, the first step is to look at which consumers you want to supply with electricity. In this article, we will show you how to determine your individual energy requirements.

Now you know the key differences between conventional generators and solar storage, and know that solar power is stored in battery storage. 

But how do you now ensure that there is sufficient energy available even during a power failure? 

Important: If you use solar energy as an energy source, you generate electrical energy thanks to the solar panel. Storage runs on powerful batteries. Only with an ideal interaction of panel and battery you have energy in an emergency.

2 Types of Generators You Should Know

There are two types of generators:

• Emergency generator (also mobile generator) and
• Backup generator (also stationary generator).

In the event of a power outage, the generator kicks in and powers the refrigerator and various other vital appliances in the home.

Conventional portable generators use propane or gasoline to produce electricity.

The alternative to the classic generator: One Power station with solar panel stores solar energy and provides your household with sustainable electricity. So you can use solar power yourself – without feeding it into the grid. 

Do I need a generator if I use photovoltaic modules?

If you use solar cells, you should also look for a clever alternative. Because switching to pure solar energy can quickly become dangerous in an emergency. 

Whether you choose one Power station with solar panel whether you decide to use conventional generators or not depends heavily on your individual needs. What is certain, however, is that you should always play it safe in order to remain able to act even if there is no external energy supply.

How long one portable power station supplies energy in an emergency, we will show you in this article.

Why do photovoltaic modules not supply any energy in the event of a power failure?

If there is a power failure in the public grid, the photovoltaic system is automatically switched off via the inverter. 

Why? This measure is primarily for protection - especially when work is being carried out on the grid, there should be no more feed-in. 

Retrofitting for emergency power supply via your own photovoltaic system is, however, quite possible. In the past, this was due to the fairly low downtime of 15 minutes per year but not necessary. 

The combination of climate change and global crises is causing punct emergency power supply but with more and more people for a rethink. 

Using solar energy: What options are there for emergency power supply?

Both the battery storage and that Solar panel with power station can reliably supply your home with electricity in the event of a power failure. 

However, there are some key differences between the two alternatives. Below we compare one Power station with solar panel with a solar battery storage.

Option 1: Der Solargenerator

A solar generator (also Power station with solar panel) stores solar energy. The generator with photovoltaic modules works in a similar way to the classic type of emergency generator. The energy source is activated automatically when there is a power grid shutdown. This is how you supply your house with sustainable emergency power. 

Some generators are large enough to power the entire house. Others provide enough power to run essential devices, such as B. Refrigerators.

In memory of: Classic generators are powered by fossil fuels. Accordingly, they are less environmentally friendly than solar generators. In order to create additional energy security, you should always take care of a backup solution. More advantages and disadvantages to the different generators as well as the Powerstation can be found in the table above.

Option 2: Complete photovoltaic system with storage

With a photovoltaic complete system, you can store excess electricity that is generated by your solar modules on sunny days. 

When the sun isn't shining, the energy stored in the battery can then be used smartly to power the home. And even in the event of a power failure, the supply is ensured thanks to batteries.

The reserve power provided by your solar panels depends on the size of the battery system you install. What does that mean specifically?

The more storage you install, the longer the backup power lasts and the more base loads are covered.

One Power station with solar panel runs on 100% solar energy. You therefore do not need any fossil fuels for the emergency power supply. One of Main Benefits the use of solar cells as an emergency power supply is that they can keep your solar panels running during a power outage by going into off-grid mode. 

If you have solar panels and a battery storage available, your solar system can be temporarily disconnected from the grid in the event of a power failure. So you can continue to generate electricity and charge your batteries during the day.

Why do I need a backup generator?

An emergency power generator supplies your home with energy without detours. They are therefore independent of the public power grid.

If you switch completely to solar energy, you have to connect your own photovoltaic system to the local power grid to ensure the energy supply. In the event of a power failure, the solar system switches off automatically.

A backup generator is worth its weight in gold in this scenario. This is how you ensure a continuous energy supply even in an emergency.

Important: Be aware of the voltage and current limits of your generator. Because if you use too much electricity, it can overload the generator. This overload can lead to failure. As soon as the power supply from the grid is stable again, you should switch off the generator as soon as possible.

Conclusion: If you want to use solar energy, you should always think of a backup energy source

In this article we have shown you that a generator is of great importance in an emergency. Whether you choose a classic generator or a power station with a solar panel depends on your individual situation. 

The first step is to determine your actual energy consumption. On this basis, you can make an informed decision about the backup energy source.
