The Solar Service Gap: Navigating the Post-Boom Era
The rapid expansion of residential solar energy in the Czech Republic has left a surprising wake of instability. Following a massive installation boom in 2022 and 2023, the market is now facing a critical “service gap.” As hundreds of installation companies have gone bankrupt, thousands of homeowners have found themselves with “orphan” systems—technology installed on their roofs but with no one to maintain it.
This shift marks a transition from a period of dynamic, almost excessive growth toward a phase of market consolidation and professionalization. The focus is no longer just on how quickly a system can be installed, but on how sustainably it can be operated over the long term.
The Phenomenon of ‘Orphan’ Installations
Many homeowners are discovering that the company that sold them their solar dream is no longer in business. This leaves them without the essential service and regular checks recommended every two years. These revisions are not merely suggestions; they are often mandatory requirements for insurance companies to maintain coverage.

The danger extends beyond missing a check-up. Industry experts report that a significant number of these external installations suffer from serious flaws. Systems that are only a few months old are being found to be incorrectly configured or entirely non-compliant with technical standards. Bringing such a system up to a proper, safe state can cost homeowners approximately 50,000 CZK.
The Cost of Maintenance: One-Off vs. Subscription
As the market matures, a new economy of third-party maintenance is emerging. Major providers like ČEZ and E.ON are now stepping in to offer services to customers who were abandoned by their original installers.
Homeowners generally face two pricing models for these essential services:
- One-time revisions: Costs typically start around 5,000 CZK, with some standard revisions averaging around 7,000 CZK including VAT.
- Subscription models: To ensure long-term stability, some providers offer monthly plans. For example, E.ON provides a service for 349 CZK per month.
Future Trends in Photovoltaic Maintenance
Professionalization and Market Diversification
The Czech solar landscape is evolving. The era of residential-only booms is giving way to a more diversified market. Trends from 2024 through early 2026 demonstrate a significant shift toward corporate installations and larger-scale projects. This professionalization is intended to replace the “turbulent” early stages of the market with sustainable growth.
government support is shifting. The 2026 iteration of the “New Green Savings” (NZÚ) program is moving away from generous grants for middle and high-income households, focusing instead on interest-free loans for up to 25 years and targeted support for low-income households.
Tech-Driven Diagnostics and Monitoring
The future of solar maintenance lies in precision. To combat the inefficiency of manual checks, the industry is integrating advanced monitoring technologies. For instance, systems based on DroneTech technologies are now being certified by the Czech Photovoltaic Association (ČFA) for their ability to reliably and accurately detect faults in PV modules.

This move toward automated, high-tech monitoring will likely reduce the cost of revisions and allow for the early detection of the “serious flaws” currently plaguing many early-boom installations.
The Warranty Trap and Global Supply Chains
One of the most challenging trends for the future is the “warranty vacuum.” Since most solar components are sourced from China, homeowners struggle to contact manufacturers directly when a part fails. Since new service providers cannot take over the warranties of bankrupt installation firms, many customers are left with no recourse.
While a third-party service check does not void a manufacturer’s warranty, enforcing those warranties against defunct installers is often a unhurried and expensive legal battle that few homeowners choose to pursue.
Frequently Asked Questions
It is recommended to perform regular checks every two years. These are also frequently required by insurance companies.
You can seek “orphan” service from established providers who offer one-time revisions or monthly maintenance subscriptions to ensure your system remains safe and efficient.
No, a professional service inspection generally does not void the warranty. But, the new company cannot “take over” the installation warranty from the bankrupt firm.
Some systems installed during the boom were not compliant with norms or were incorrectly implemented. Correcting these fundamental errors can cost around 50,000 CZK.
