Written by Identification of photovoltaic installations problems

Properly designed, optimized and well-made photovoltaic system can operate flawlessly for many years. However, problems often arise from photovoltaic installations, which can cause many problems.

Qualified ENIS employees perform photovoltaic expertise, identify defective parts, materials, installation errors and verify the correctness of the photovoltaic systems operation as well as the correctness of the design and installation.

ENIS company has its own laboratory, equipped with specialized equipment and software for conducting research of photovoltaic panels and inverters.

ENIS carries out expert’s reports about photovoltaic installation for:

• courts, prosecutor’s offices,
• Companies and institutions,
• individuals.

Each customer will receive detailed documentation review and evaluation of a photovoltaic system.

Opinions and expertise of photovoltaic installations prepared by ENIS can serve as proof of the court.

Problem situations, ENIS experts most often meet:

• degradation of PV system performance,
• expected rate of return indicated by the manufacturer or installer is different from the real one,
• small changes in performance regardless of weather conditions,
• obvious visual changes, graying, yellowing, moisture stains on photovoltaic modules,
• visible dark streaks (worm patches) on particular cells of the photovoltaic panel,
• the connection between the objectives are deformed or corroded (they become brown) - create a hot-spot. Note: in this case there is a risk of fire,
• hot solar wires,
• incorrect cable routing,
• torn wire insulation,
• photovoltaic equipment damage,
• inverter’s noise and display the error messages,
• switching off the inverters (especially in the afternoon on a sunny day),
• lack of charging of batteries,
• battery replacement is required every year (quickly depleted),
• previous repair did not bring any improvement,
• deformation of the frame and plate of the photovoltaic module due to snow load,
• PV system damage by lightning (lack of or inadequate lightning protection),
• the delivered modules are different from those set forth in the offer (contract),
• lack of control card of the photovoltaic module, according to the data sheet,
• suspicion of falsifying data sheet of the photovoltaic module,
• theft of photovoltaic installations,
• the insurance company refuses to pay compensation for PV system damage.
