Photovoltaic system documentation
Dear Mr. Lawyer,
In 2011, I decided to install a photovoltaic system and after various offers, I chose LCS Solarstrom AG. During the on-site inspection, the company Elektro Moerschen Deckers GmbH & Co. KG was introduced to me, which will take over the entire processing and all warranty claims. And so the order was placed. After a time-consuming installation, we started operation in October 2011. As agreed, I settled the invoices according to the payment terms. I withheld the final payment of 10% as there were still modules and the complete documentation according to the VDE standard missing. After receiving the first documentation, I noticed that it did not match my system and sent it back. Since LCS Solarstrom AG had assigned the warranty claims to Elektro Moerschen Deckers GmbH & Co. KG when awarding the contract, I also requested the warranty bonds. On 03.11.11, I requested the remaining claims and indicated that invoice no. 17559 would not be settled for the time being. Faulty or incorrect documentation was returned on 11.11.11. I requested: 1. to specify an acceptance date 2. the missing documentation with all test data and overview sketches showing where the delivered modules were installed. Which measurement method was used to measure the modules on site. 3. warranty declaration for all services provided 4. unlimited warranty bond for the system (10 years) 5. The fourth module is already showing a different color 6. Written explanation of what the procedure will be in case of system failure. Contact person, how long your team will be on site, etc. The received invoice no. 17559 will not be processed for the time being. If a 5% unlimited warranty bond for the system (10 years) is provided, the due amount will be processed. Once again, there was no response from Elektro Moerschen Deckers GmbH & Co. KG. On 13.12.11, I sent a reminder to Elektro Moerschen Deckers GmbH & Co. KG. On 20.12.11, a roofer was supposed to replace the indicated modules, which I declined as a roofer is not allowed to work on an existing system according to the VDE regulations. Dates for the replacement of the modules were agreed upon but not adhered to. I had to take time off work for this. The modules were replaced on 23.02.2012 except for one element, and the documentation was incomplete. In the handover report, I listed the missing documentation, 1 missing module, and the warranty bond as defects. There was no response from Elektro Moerschen Deckers GmbH & Co. KG to any of my letters. On 08.03.12, I received a newly created documentation, which is still incomplete. Therefore, on 11.03.12, I requested the following by email: Dear Mr. Deckers, After reviewing the documentation, there are still clarifications needed from my perspective. Inspections of PV systems according to DIN EN 62446 VDE Sections 4.2, 4.3, 4.5, 4.6 should already be considered. 1. Warranty information for PV modules and inverters, start date of warranty and warranty duration 2. Information on the applicable quality of execution or the guarantee of waterproofness 3. Test results of all AC circuits according to VDE DIN 4. Protocols of continuity tests of protective and equipotential conductors 5. Polarity test protocol of each string 6. Protocol testing the open circuit voltage of each string 7. Protocol testing the short-circuit current of each string 8. Functional test protocol 9. Insulation resistance protocol of DC circuits 10. Explanation of the procedure in case of system failure, contact person, phone number, and time frame for the technician to be on site. 11. Mounting system manufacturer, attachments, etc. 12. Information about the cables installed 13. The string cables were marked with a white pen, how long is the legibility guaranteed? 14. Warranty bond (see letter of 03.11.11) If these protocols are included in the documentation, please provide clarification and review. I would like to refer again to the letter of 29.09.11, where I took a day off work and no technicians appeared. Only after speaking with Mr. Waldhoff, he mentioned that you, Mr. Deckers, wanted to cancel the appointment. For this and for the inspection of the modules (replacement), I ask you to transfer the amount of 2 times 150.00 euros to the following account by 15.03.12. On 03.10.12, I returned the original invoice from 26.
