What is Solar Energy in Germany?

Germany, despite being a sun-drenched country has been considered as one of the highest solar power outputs around the world and still possesses the most advanced and latest research about solar energy and has many new industry actors. Moreover, they’re expecting for the second wave of solar power expansion, which will soon bring success and progress for the solar technology’s full systemic integration.

For several years, Germany has been considered as the world’s top PV installer among other countries. At the end of the year 2016, Germany managed to build a total installed solar power capacity of 41.3 gigawatts (GW) which was behind China’s solar capacity.

Most solar power in Germany exclusively consists of photovoltaics (PV) systems only. Germany has only a little interest in concentrated solar power (CSP) for it does not use photovoltaics and this solar technology requires much higher solar insolation as compared to the PV system. However, there is still an experimental CSP-plant with 1.5 MW capacity which is being used solely for on-site engineering purposes only rather than for commercial electricity/power generation. This concentrated solar power is called the “Jülich Solar Tower” that is owned by the German Aerospace Center.

Moreover, in 2014, Germany managed to install about 1.5 million photovoltaic systems across the country which are ranging from small rooftop solar power systems to medium commercial and large utility-scale solar plants and farms. The largest solar farms of Germany are located in Neuhardenberg, Templin and Meuro with solar capacities of over 100 MW. Moreover, these PV technologies were accounted for an estimated 6.2 to 6.9 percent of Germany’s net electricity generation in the year 2016.

However, new installations of photovoltaic systems have slowed down steadily since the beginning of the year 2011. Also, it was estimated in the year 2017 that over 70 percent of the employment in the solar industry of the country have been lost in recent years. Solar power in Germany has gone through rough times since it has been started in the wake of Germany’s Renewable Energy Act in the year 2000. However, German companies quickly loomed to global leadership in solar power technology before a collapse in the solar industry happen and some of the companies were forced to hold their businesses.

Proponents from the Photovoltaic industry blamed the government for its lack of commitment in the said industry, while others point out that the loss of jobs in the solar sector is due to financial burden that was associated with the fast-paced launching and manufacturing of photovoltaics, which in their perspective was very unsustainable to the transition of renewable energies.

With all of these, still, the official governmental goal of Germany is to continuously improve and increase the contribution of renewable energy to the country’s overall electricity generation and consumption. By 2020, Germany is aiming for a long-term minimum target of 35 percent capacity, 50 percent by 2030 and around 80 percent power capacity by the end of 2050.

Currently, the country is significantly producing more electricity at specific times with high solar irradiation than the country’s needs, slowing down spot-market prices and exporting the country’s electricity surplus to nearby countries. In 2014, the record of exported electricity surplus reached almost 34 TWh. The decline of spot-prices in the market may raise the electricity prices for retail customers, as the expansion of the guaranteed feed-in tariff and spot-price increases as well.

As the combined share of fluctuating wind and solar energy is nearly achieving 17 percent of the national electricity mix, energy issues and problems are also being prevented and others becoming more manageable. This is because of the electrical grid adaptation, new grid-storage capacity construction, reduction of fossil fuels, altering of nuclear power plants and constructing a new generation of combined heat and power plants. Today, nuclear power and brown coal are the cheapest suppliers of electricity in Germany.

Ground Mount Systems for Solar

When you install a solar panel system at home or your working space, you have different mounting ways to choose from. Although you observe that most residential and commercial properties have solar panels installed on their rooftop, that’s not the only means. Besides, that is the only traditional way of placing your solar panels. There are several ways to place and install your solar power systems. Among the methods of installing solar panel systems, the ground mount system is the most common one.

In today’s article, we will explain what a ground mount system is, its cost, benefits, and other important things you should know about it.

What is a Solar Ground Mount System?

Let’s simply put it in a simpler way. From the words “ground” and “mount” a ground mount solar power system is a way of mounting or installing your solar panel system on the ground or any large field near your property rather than installing them at your property’s roof. This type of ground mount system is a good alternative solar solution if you don’t want to place it on top of your house. As long as you have a large yard or field near your place and there is abundant sunlight in your area you can easily have your solar panels installed. Usually, the panels are placed anywhere from a few inches to a few feet off the ground, depending on how your installers set up the racking system.

Types of Ground Mount Systems

The ground-mounted solar system has two main types: standard ground mount and pole mount. The standard one is the same as the pole-mounted ones, the only difference is it is not elevated on poles but rather directly installed on the ground using ground anchors to hold up a racking table. 

A standard mount system is also easier to install as it typically holds the solar array in a fixed position on the ground. Besides, it is a more cost-effective solution for a ground install compared to a pole mount system that usually has tracking systems, resulting in a higher cost per watt. 

Meanwhile, a pole-mounted system acts as a support system to the ground-mounted panels. Since they are elevated on poles, they can easily get maximum sun absorption. Not to mention that they have a monitoring option that allows the solar panels to angle with the sun’s direction.

What Properties are Applicable for Ground Mount Systems?

You can get your solar panels mounted on the ground for your residential or commercial properties as long as you have an open space to place them. Typically, for a residential home, you will need 60-cell solar panels, same with the solar panel size used in residential roof solar installations. Solar farms and bigger facilities are also applicable for ground-mounted solar installations. These properties need larger-scale ground-mounted systems, usually 72-cell solar panels to power the entire building. In this case, a wider field or ground space is needed to install the solar power system. 

How Much Does it Cost to Get a Ground-Mounted Solar System?

When it comes to residential and commercial/agricultural properties, there will be a significant difference between the cost of ground-mounted solar panels installation before and after applying incentives. To give you an estimated cost, the average residential property can expect to pay between $23,000 and $46,000+ to get a ground-mounted solar system, but prices still vary depending on the size of solar panels. Whereas, commercial and industrial properties can expect to pay $66,000 to $200,000+ to install a ground-mounted solar system. 

Wholesalers

Solar Products Wholesalers 

Wholesaling refers to buying some products or goods directly from its manufacturer usually at a discount and then reselling it to the retailers for a comparatively higher cost than the original. Basically, wholesalers handle products and package them in small quantities and then sell them to retail customers, either for commercial or personal use. 

Many industries have wholesalers, and that will not skip the solar industries. Nowadays, many solar wholesale stores/firms are operating across the globe, making it much easier for retailers to go solar. Sometimes retailers find it hard to reach direct manufacturers of solar products because some companies do not have their solar stores/shops in public, with that they are not also offering solar products per piece. Through wholesale solar stores/shops, these individuals can easily buy the solar products that they need to replace or maintain their solar systems. 

If you are in need of solar product suppliers for an individual purpose, you may visit some solar outsourcing marketplace to get an updated list of solar wholesalers near your location. There are many solar platforms that provide enough information and data about the solar industry in your region, including all the reliable solar wholesalers in town.
