Are solar panels worth it?

To the solar panels

In times of a looming energy crisis and skyrocketing prices, the answer to this question seems obvious. However, some consumers are still reluctant to invest in renewable energy sources. In this post, we explain in detail the advantages and disadvantages of solar power systems so that you can make a qualified decision.

Factors affecting the value of a solar power system

Is a solar system worth it? To answer this question, let's look at several factors that increase the value of your solar power system.

Insolation at installation site

Solar panels convert sunlight into electricity using photovoltaic (PV) cells. The electricity is either fed into the grid or stored in batteries. Maps like the Global Solar Atlas help you explore the solar potential of your region

As a rule of thumb, the more sunlight there is, the more electricity can be generated.

Tax incentives for solar systems by local authorities

Depending on your jurisdiction, you can get valuable tax benefits if you choose to install solar. This makes the investment much more affordable, increases your return on investment (ROI) and allows you to break even much faster.

Off-grid vs. on-grid solar systems

With grid-tied systems, the energy you generate is fed into the power grid, which in turn is distributed to other people. This lowers your monthly bills and gives you a quick ROI. With off-grid systems, on the other hand, the energy is stored in an additional battery for later use. If you want the best of both worlds, consider adding a battery to your grid-tied system to be prepared for power outages.

payback period

The faster you can earn back your investment, the better the purchase. Calculate your costs and consider the tax incentives offered by your local government. In the US, the payback period for solar panels averages between 5 and 15 years, depending on the state.

Usage Scenarios

Last but not least, the choice of solar system mainly depends on your personal preferences. If you enjoy camping or exploring the great outdoors, you might opt ​​for a portable power station with solar panels over a grid-tied system. Portable power plants also provide backup power during power outages.

When are solar panels worth investing in?

Solar panels are a worthwhile investment if you want to reduce your ecological footprint, reduce your electricity bills, have a backup solution for power outages and gain more independence for your next outdoor adventures.

Advantages of solar systems

Large-scale innovation and rising energy costs have persuaded more consumers to switch to solar power. Each of the following contributes to the value of solar energy.

Sustainable Energy

Consumers today are more environmentally conscious than ever. Since solar energy is a renewable energy source, you can significantly reduce your carbon footprint, which summarizes all the greenhouse gases you produce. Installing sustainable solar panels avoids environmental damage and contributes to a greener planet.

Lower utility bills

In some parts of Europe, energy costs have risen by more than 40% in recent months, imposing a huge financial drain.As a result, consumers are looking for ways to cut costs and get through next winter. Solar panels can help you reduce your electricity bills and provide a positive return on investment over the long term.

Backup power

Depending on your location, there may be occasional power outages that may last several hours. A solar power plant allows you to store the energy in a battery and use it when needed. This is not only convenient, but also essential for people who use CPAP systems at home.

More independence

Solar power plants make you more independent, no matter where you are. If you enjoy exploring the great outdoors, camping, or traveling, portable power stations are the right choice. These allow you to charge your phone and other necessary devices, so you never run out of power.

Easy Maintenance

Solar modules are the right choice for almost every consumer, even if you are not tech-savvy. Solar panels have no moving parts, which contributes to longevity. Depending on the module used, you can also assume an average service life of 25 years.

Solar Set

When are solar panels not worth the investment?

Apart from the tremendous benefits, solar panels have high acquisition and maintenance costs and depend on sunlight.

Disadvantages of solar systems

Before you buy a new stationary or portable solar system, you should consider the following disadvantages.

High upfront investment

Depending on your location and the type of solar panels you use, the initial investment can be quite high. In the US, a typical 5-kilowatt (kW) system can cost $15,000 to $20,000, not counting tax credits and incentives. Adding a battery further increases the cost. You will still save money in the long run.

Maintenance costs

In addition to your initial investment, there may occasionally be maintenance costs. Fortunately, since there are no moving parts, the system is relatively stable. Nevertheless, the solar modules must be cleaned regularly, since dirt or leaves can impede the sun's rays.

Dependence on sunlight

Solar panels only work with sunlight. This can become a problem in some parts of the world where the sun shines less brightly. Also, solar panels don't work at night, which means you should install a battery to store enough backup power.

Not all panels are created equal

Depending on the manufacturer, the solar modules offer different levels of efficiency and durability. That means you need to exercise some diligence before choosing the right manufacturer. Therefore, be sure to choose market leaders and well-known companies to make the right choice.


Coming back to our original question: are solar panels worth it? It mainly depends on your requirements and whether you can accept the initial investment costs.

The initial costs are easily recouped: If you are willing to make the initial investment and equip your system with strong batteries, you will reap the benefits from an independent and renewable energy source that will reduce your costs in the long term.

In summary, if you want to contribute to a greener planet, reduce your electricity bills and install a backup power supply to be more self-sufficient during power outages, is a solar system, whether grid-connected, off-grid or portable, is the right choice for you.
