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.

What Is a Solar Inverter?

A solar inverter, also known as a PV inverter, is a type of electrical converter that converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. Basically, a solar inverter is a critical balance of system (BOS)-component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. For this reason, solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking (MPPT) and anti-islanding protection. 

What Are Some of the Necessary Accessories for Solar Inverters?

The solar inverter is a complex device, and so, it is made up of so many accessories. The following are some of the accessories that are must-haves for solar inverters. 

  • Battery Charger. A battery charger, also known as a recharger, is a device that is used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it. 
  • Battery Isolator. A battery isolator is an electrical device that divides direct current (DC) into multiple branches and only allows current in one direction in each branch. The primary benefit of such an arrangement is the ability to simultaneously charge more than one battery from a single power source (e.g., an alternator) without connecting the battery terminals together in parallel. 
  • Solar Charge Controller. A solar charge controller, also known as a charge regulator or battery regulator, is a device that limits the rate at which electric current is added to or drawn from electric batteries. 
  • DC-to-DC Converter. A DC-to-DC converter is an electrical device that converts direct current (DC) of a voltage level from one source to a different voltage level at another source. 
  • Power Optimizer. A power optimizer is a DC-to-DC converter that increases energy output from PV systems by constantly tracking the maximum power point (MPPT) of each module individually. 
  • Power Inverter and Solar Deep-Cycle Batteries
  • ANL Fuses and Fuse Holder Kits
  • Power Inverter Battery Cables
  • Power Inverter Remote Switches
  • Transfer Switches. A transfer switch is essential when using a power inverter that is connected to an AC source so that the inverter is not “back-fed” when power is applied to the same line. 
  • Travel Plug Adapters
