What are the benefits of a cloud-based virtual power account?

During the summer, your solar system will generate a lot of power.

It can no longer be utilized or temporarily stored once a specific quantity is surpassed. Many homes believe that a solar system is not financially viable since the feed-in tariff has been declining for several years while power costs have been gradually rising.

The exact reverse is true. You may digitally store extra power in an “electricity account” thanks to a self-sufficient cloud solution. For a modest cloud charge, you may subsequently access this electricity and utilize it to power your house on your own. Simple, digital, and transparent are three words that come to mind while thinking about this design.

What is photovoltaics solar and how does it work?

Photovoltaics has evolved from costly space technology to the cheapest and most common type of energy with the fastest growth rates in the world in the previous several decades. Solar energy systems create electricity by harnessing the sun’s energy, making them a clean and long-term source of energy.

Individual solar cells, which are increasingly common on roofs, are made of polycrystalline or monocrystalline silicon. Solar energy sets electrons in motion in these solar cells, converting them to electricity. This is direct current, which may be converted to alternating current before being consumed or sent into the electricity system.

What is the difference between photovoltaic and solar thermal energy?

Both systems rely on the sun’s beams for energy. Solar thermal energy, on the other hand, converts solar energy into heat. This is accomplished by pumping a heat transfer fluid through the collectors, which transfers the heat. The household water in the house or yard and the radiators may be heated in an ecologically beneficial manner in this manner.

Photovoltaics, on the other hand, are used to generate power. It transforms solar energy into electricity that may be utilized in the house, supplied into the power grid, or used to heat and cool domestic water. In a meeting with us, you may learn how to use the electricity you’ve generated for your personal energy requirements in a variety of ways. The benefit is

What are the advantages of having a solar power system for your home?

Are you on the lookout for a dependable power source? You don’t want to rely on the public internet? Then installing a solar system is the best option. You will be less reliant on external energy sources with solar solutions. You will no longer be concerned about rising power costs. Home owners that use solar energy also help to safeguard the environment.

No other source of energy is as pure and environmentally friendly. It’s no surprise that the federal government is depending on solar energy to fulfill its lofty climate goals. In addition, if you ever decide to sell your home, the solar system will improve the value of your home. Environmental and economic benefits are inextricably linked.

When it comes to solar energy systems, how long do they last?

A lengthy service life requires high-quality components, expert design, and installation, as well as adherence to the most recent technical requirements and safety procedures. You need to get in contact with a good company known to offer best quality solar product and installations.

How does a solar energy system’s feed-in tariff work?

To promote alternative energy and safeguard the environment, the federal government implemented the feed-in tariff in 2000. Photovoltaic system owners continue to profit from this rule since the solar system frequently produces more power than is utilized in the residence.

The feed-in tariff is available from the first month of commissioning and is valid for 20 years from the beginning of the year. The feed-in tariff is still a compelling argument for homes to convert to solar energy.

When the feed-in tariff expires, what happens to my old solar system?

From the date of commissioning, the feed-in tariff is valid for 20 years. Following that, no additional financing will be available, according to the existing situation. You now have several alternatives as a solar system owner.

You may continue to enjoy the benefits of this ecologically friendly energy source for your own house by operating the system as previously. If you drive an electric car, you may even use the power created to charge the vehicle’s batteries. You may also sell your power to an electrical trader. However, several legal requirements must be followed for the letter.

Is a construction permit required for my solar energy system?

No, according to the Building Code (BauGB), solar systems do not require permission to be installed. This is especially true for solar systems that have photovoltaic modules mounted parallel to the roof or facade. On the other hand, solar systems are a change in look if you reside in a listed property. In this case, the local building authority must determine if the installation is legal.

Are solar panels ineffective at night or in the winter?

Of course, when there is intense, direct sun radiation, the performance of solar systems is at its peak. However, photovoltaic systems are a good choice for self-sufficient energy generation even in Northern European locations with low sunlight.

Even on gloomy or dark days, the systems provide adequate electricity. The explanation is simple: snow reflects sunlight, and cold temperatures improve solar cell performance. As a result, you have a consistent supply of energy for your house throughout the year.

What is the frequency of power outages?

Currently, power interruptions are neither common nor long. Your power supply, that is, the power supply of the end-user is slightly under 100 percent. Consumers were without power for slightly over 15 minutes in 2017. In 2018, it took a little over 14 minutes.

Longer-term power outages are always accompanied by greater or less significant warnings. However, if you currently have or intend to install a solar system, you should also seek guidance on a backup power source.

How can I safeguard myself in the event of a power outage? A diesel generator is the most common type of emergency generator. The not-so-environmentally friendly emergency power generator will only help if you have fuel or petrol on hand in the case of a power outage.

However, in the long run, a solar system with a storage system and an emergency power function is beneficial and ecologically good. As a result, even in the case of a power outage, your solar system’s battery storage can provide you with electricity.

What is the definition of emergency power?

Critical infrastructure, such as hospitals, computer rooms, nuclear power plants, chemical and military installations, all require emergency power. It has to be ready as soon as feasible, ideally within a few milliseconds. As a result, emergency power is often known as an uninterruptible power supply (UPS).

What does backup power entail?

Where the transition to emergency power is not as time-critical as in the instances for the question “What is emergency power?” backup power is employed. This is true in private houses, for example. The fact that the residential power grid is first physically removed from the power grid causes a time delay of 100 milliseconds to a few seconds.

The stored power is subsequently made available to 1-phase users, for example, via a 230V plug. 3-phase customers can be supplied with backup power depending on storage capacity, which is also dependent on the roof area.
As a result, the power reserve that your solar system provides might be referred to as backup power.
