How much can a roof photovoltaic system cost?

Anyone who has ever thought about the question will get many different answers.

Every offer that lands in the customer's mailbox upon request is like a surprise egg. They are usually quite different in terms of content and, above all, hardly comparable. There is no intention or malice behind it, because every installer and/or solar engineer has his own philosophy and idea of ​​an optimal roof PV system.

Unfortunately, this often means that the needs and requirements of the customers with the philosophy and presentation of the providers about sales must be made “suitable and bent”. This is not supple and mostly not in the customer's interest.

And because the market is currently booming, it is also attracting providers who work on this part-time or part-time and, due to a lack of experience and knowledge, can only offer what the solar company currently has in stock for which the external sales team actually works. Ultimately, it's always about the commission and what you can earn from it. This is also legitimate, but not always in the interests of the customers.

Even if the respective offers are difficult to compare, there are a few points that you can pay attention to and explain why these price differences exist.

Every offer has its justification. It always becomes difficult when you realize afterwards that you didn't know that and that you assumed something else. Therefore, objective and independent advice with comprehensive foresight is always recommended. Because it is precisely in an open conversation that new knowledge can be gained - for both sides.

We are talking about projects starting at 10,000 euros and well beyond that. That's a lot of money. Not only competence but also trust plays an important role.

Currently I can identify four (approximate) price levels on the market. This refers to a PV roof system with 10 kWp and electricity storage: €10,000, €26,000, €32,000 and €42,000. All net prices or with 0% VAT.

With such large price differences, everyone has to critically question what exactly is behind them. Can that be true?

I want to get to the point: there are no bargain prices simply due to the current market situation. At first glance, €10,000 seems affordable and cheap. Others suspect there is a catch here. Both sides are right.

New: Current price offers

A direct comparison of the systems is generally difficult. However, they can be a guide as to whether someone is completely overpriced or a little too cheap, where the devil is in the details.

We regularly scan the supply market and always obtain current offers. You are also welcome to send us your offers and have them checked without obligation.

Here are the current offers available:

  • €36,000 for a 10 kWp system with suitable electricity storage
  • €30,000 for an 8.0 kWp system with suitable electricity storage
  • €24,000 for a 6.6 kWp system with suitable electricity storage

The four price levels

Here is a rough overview of the respective price levels for a PV roof system with 10 kWp and electricity storage as an example , which only gives an approximate insight and is not complete. The purpose of the list is to raise awareness and help customers understand the price segment they are in and their own ideas and requirements.

A) €10,000 PV system

Systems worth €10,000 are usually package offers, without installation and without electricity storage. The main components are the substructure and the inverter. Generally the products are of ok quality. Very suitable for projects with self-assembly, taking into account that the building law requirements must be adhered to and acceptance requires a master electrician.

➡️ Such offers are largely processed via online trading.

B) €26,000 PV system

With PV systems, everything seems to be there for around € 26,000: solar modules, hybrid inverter, electricity memory and installation. The difference to the following offers is in detail. Most of the time, the legally necessary scale structure is missing here, which must be placed “construction”. The term “construction” is erroneously understood by the lay that the construction company takes over the appropriate work. However, the opposite is the case. The client (client) must arrange that himself.

➡️ Such offers are mainly offered by smaller one to five-man companies. In general, accessibility, order processing, technical support and after-sales also need to be questioned here.

With after-sales

  • Customer service and post-sales communication,
  • Maintenance, repair and spare parts management,
  • Complaint support and guarantees

meant. In general, after-sales needs to be critically examined, even in larger companies. How a company deals with its customers in the future is one thing. But how a company solves support due to low staffing levels is another matter.

C) €32,000 PV system

Actually everything as under point B). What is interesting here is that these are mostly products with a longer or extended warranty period. Scaffolding is also available. This includes project planning, advance registration with the responsible network operator, network management and registration to the low-voltage network as standard.

➡️ Such similar offers largely come from companies with larger staffing levels that offer dedicated customer support.

D) €42,000 PV system

In fact, there is more! Generally “Made in Germany”, maximum security with a minimal risk: investment protection, product and assembly guarantee. On everything 20 years! Establishment of prepayment. Payment only after a contractually performed service. No glass film modules, but high-quality glass-glass modules with excellent low lighting behavior are used to name just one further qualitatively important point. In -house storage production offers additional added value.

➡️ Large company with over 1,800 regional specialist consultants and individual contacts at the highest level.

What are the advantages of investing more in photovoltaic systems than in cheaper systems?

The far longer guarantee periods and extended guarantee services are intended not only to minimize the investment risk, but also to reflect the high quality of the service and products.

By using high-performance double-glass modules, the aging process is slowed down, in contrast to common glass-film modules, because glass is known to hardly age.

This longevity of the modules means that the photovoltaic system can also be used to generate solar power for longer. The return increases.

In contrast, glass film modules only have a glass pane on the front. There is a very thin film on the back, which makes the modules more susceptible to signs of aging.

In general, modules differ in their performance. Modules with higher efficiency and excellent low-light behavior are priced higher, but over time they provide more performance and therefore a higher return.

And what is Xpert.Solar? Where is the added value?

We are independent and are not focused, limited or contractually bound to specific manufacturers, products or module substructures/fastenings for a solar system to be planned.

The aim is to be able to offer the best possible and most efficient solution . The focus of our actions is not on the products for the solution, but on the challenge to be solved.
