SPECIAL OFFERS FOR THE TESTING OF PHOTOVOLTAIC PANELS

SUN ENERGY SOLUTION SUN ENERGY SOLUTION offers you a UNIQUE OPPORTUNITY.

You have the ability to test your photovoltaic modules completely at extremely low prices.

  • Household Photovoltaics up to 10 KW, in the amount of 50 €.
  • Photovoltaic Parks up to 100 KW, in the amount of 150 €.
  • Photovoltaic Parks up to 150 KW, in the amount of 200 €.
  • Photovoltaic Parks up to 500 KW, in the amount of 400 €.
  • Photovoltaic Parks up to 1.000 KW, in the amount of 600 €.

The testing includes:

  • Taking thermography pictures on all PV Panels of the Plant.
  • Sample testing of the electrical parts of photovoltaic panels that thermographically DO NOT INDICATE problems. More analytically, we perform:
    1. Measurement of Insulation Resistance of the Photovoltaic strings.
    2. Measurement of Open Circuit Voltage & Short Circuit Voltage (Voc / Isc).(Voc/Isc)
    3. Measurement & Display of the Current / Voltage (I / V) curve & the Voltage / Voltage (P / V) curve.
    4. Determining the Actual Performance ratio of PV Modules.
  • COMPLETE testing of all electrical parts of the Photovoltaic Panels that thermographically DO INDICATE problems.
  • Taking thermography pictures for the entire installation and a Drawing a report for all the collected Thermography Data.

Problems in Photovoltaic Panels

  • Corrosion in overlay and insulation strips of cells contacts due to overheating of PV panels.
  • Visible damage in the EVA coating of panels with simultaneous reductions of their performance.
  • Diode failure on photovoltaic panels. I / V chart shifting.
  • Hot spot effect on photovoltaic panels. I / V chart shifting.

At the completion of our testing, we provide:

  • An electronic file with the total of thermography results of the photovoltaic panels together with corresponding photographic material.
  • In both electronic and hardcopy form, the measured electrical characteristics of your photovoltaic panels, the performance of the panels at the time of measurement, as well as the DEVIATION of the performance of the panels from the manufacturer's stated performance.
  • In both electronic and hardcopy form, all thermographies, photographic material and electrical measurements of Photovoltaic Panels that appeared problems at the measurements.
  • REPORT of the thermography data and conclusions for the actual functional condition of your photovoltaic panels.

IDENTIFICATION OF THE PID PHENOMENON (The so-called Disease of Photovoltaics)

The early preventing testing of photovoltaic panels for the appearance of the PID phenomenon is extremely important so that the necessary measures can be taken to restore the panels to their original performance. In the event that the reduction of photovoltaic panel output exceeds 30% due to PID effect, restoring the photovoltaic panels becomes IMPOSSIBLE. The testing and maintenance works on photovoltaic installations are carried out by experienced and highly trained engineers and technical staff of our company with the assistance of all the necessary instruments, the most important of which are:
  1. METREL MI3108 EurotestPV multi-functioning photovoltaic testing unit
  2. FLIR i7 thermal camera
  3. METREL MI3122 ZLine-Loop / RCD for overcurrent protection & short-circuit and leakage protection
  4. Insulation Tester DI-6200
  5. Earth Resistance Tester MS 5209
  6. 3 Phase Digital Power Clamp Meter MASTECH MS2205
  7. Digital Multimeter MASTECH MY-67
  8. Clamp Tester LUTRON DM-6046
  9. Thermal Leak Detector TLD100-XJ

The above amounts do not include VAT (24% or 17%) or travel expenses outside the Attica Basin which are calculated at 0.25€ per kilometer.
However, we can achieve to lower significantly the travel costs if the scheduled works can be carried out in conjunction with other nearby installations.
