photovoltaic prices offers Read and understand photovoltaic offers correctly
You do not need to be a tech professional to read and understand photovoltaics. Here's what to look out for.
Many people only buy one photovoltaic system in their lifetime. It's located in your home, your business or your farm. Unlike a car, they have no personal experience with the technology and must rely on what the company they trust promises.
Another point is that every newly installed system provides electricity for many years. However, there are quality differences in components, coordination of system consumption and performance, and service.
The first step to a good photovoltaic system is a professional offer. But what does such a professional offer look like and how can someone with no experience with photovoltaic systems determine if an offer is good or bad? It is very important that those who focus only on price can fall on their face.

Photovoltaics and accessories
Anyone who has installed a photovoltaic system between 2004 and 2013 can remember that the biggest problem at that time was the supply of components. The offers were openly designed accordingly and there was no evidence that the providers did not keep the options for alternative products open.
What was available today was installed. The main thing at that time was to install and activate systems at the right time window, to connect to the internet before the next grant cut, in order to collect the highest possible grants during the 20 years of the state-guaranteed EEG.
photovoltaic prices offers. Today the subsidies are low and the systems are installed for personal consumption. These are power stations that have been supplying a site with green electricity for decades and should minimize the grid purchase and, therefore, the electricity bill. Therefore, it is important to have the right components that accurately fit the site requirements.
photovoltaic prices offers Prospective operators can now expect that all components of a photovoltaic system, from inverters to cables, modules to infrastructure and communications, are clearly stated in the offer and are also installed in their photovoltaic system as described.
What distinguishes a good photovoltaic offer?
The answer to this question is "transparency". A good photovoltaic offer describes in a comprehensible way to the photovoltaic peoples what they are spending their money on. With their photovoltaic offer, customers have an ideal idea for their future solar energy generator.
Here are eight elements of a good offer:

1. The image of the new photovoltaic system
The display of the whole system. Before installing, you need to know how your future solar energy production will affect the overall appearance of the building and its environment. To this end, installation companies now use photographs of buildings in which the units are positioned correctly in terms of perspective, so that customers have a realistic idea of the outcome of the integrated system. This is the visual part, followed by technology.
2. Clear statements about technology
photovoltaic prices offers The photovoltaic series must provide a detailed technical description of all components. Photovoltaic modules are named after their production, manufacturer, design and characterization. Infrastructure is described by name, wind and snow loads, either in a roof system or inlay and whether it is a fixed junction or a simple double rail installation.
Cables, inverters, communication, lightning and generator system ground are also part of the offer with an accurate description. If this information is missing, bids cannot be compared.
3. Safety during installation
photovoltaic prices offers The issue of occupational safety is very important because building owners are equally responsible for securing the construction site as the installation company performing the work. All involved are responsible if an accident occurs during installation or pay a fine if violations are reported. This is why good photovoltaic offers contain a clear description of fall protection, scaffolding and work equipment for transporting materials such as telescopic loaders, work platforms and ramps. Then you are sure that the company complies and meets all safety rules.
4. Storage of electricity
Whether you need storage, what capacity, with what power and how many phases depends on the consumption profile at the place of use. There are definitely cases where a storage system does not make sense even today. This should be clarified with the installation company in a personal conversation. If you are interested in an emergency power supply in the event of a power outage, then this feature should be explicitly described in the offer, as not every storage system can guarantee an emergency power supply.
5. Network connection
photovoltaic prices offers As a rule, photovoltaic systems are installed with a connection to the public power supply network. This is desirable for the energy transition in order to supply excess electricity to the public grid, but is only possible in coordination with the grid administrator. The bid should clearly specify who undertakes what tasks communicates with the network operator. Another point is the meter housing, which must accommodate additional measuring, measuring and safety devices for the photovoltaic system. The offer must clearly describe whether the existing meter cabinet is large enough or whether it needs to be expanded or completely replaced. For all changes, the offer must include clear information about who is doing the work and the expected costs.
6. Auxiliary work
7. Delivery, storage and disposal of the package may look like returns and ends. Anyone who has ever seen the installation of a photovoltaic system knows how much cardboard is involved and that it is not the "normal household" quantities that should be disposed of in recycling centers.
8. Acceptance, instruction, documentation
photovoltaic prices offers After the installation of a photovoltaic system, regardless of whether it is with or without a storage system, the acceptance is made by the customer, professional instructions for the proper operation of the system and the delivery of detailed system documentation according to the standard. These positions also belong to a good offer.
9. Presentation of profitability
photovoltaic prices offers In this position, economic milestones appear in the life of a photovoltaic system, which calculate an "return on investment" from the calculation of return, investment cost, same consumption, supply and supply fee. Profitability is a look at the future based on existing data. Taking a conservative approach is a great way to protect yourself from unpleasant surprises. Worry if you are promised too much profit in this position, for example through unrealistically high annual electricity price increases.
Depending on the customer, the individual points of the offer can be resolved differently. For private clients living in an exclusive building, visualizing the entire system may be more important than for a commercial site or farm. For companies, protection issues, cargo profiles, network connectivity, ancillary work, and coordination of consumption and production will make up the bulk of the supply.
It is important that all points appear in the supply in such a way that even the photovoltaic peoples have a clear and detailed idea of the technology, performance and vision of their future solar station. This should provide clean energy for personal consumption as reliably and smoothly as possible for many decades and, as part of the energy transition, actively contribute to global climate protection.
