Periodic Mechanical Maintenance
Solar doctor will maintain and assess the mechanical fixings and mounting components of the solar photovoltaic array as well as solar panel inverter repairs. This will include:
- Annual visual inspections to ensure that the array and or building structure displays no signs of malfunction, possible areas of corrosion, mechanical stress and degradation of the mechanical structure of the solar photovoltaic array.
- Annual visual and manual inspections of any joints, fastenings and fixings to ensure that the mechanical mounting structure of the solar photovoltaic array is secure and shows no signs of loosening that may have been caused by wind, vibrations or wear. Joints, fastenings and fixings will be tightened where necessary.
- Annual visual and manual inspections on the solar photovoltaic modules to ensure they are fastened securely, this check will be done by hand where possible and re-secured where necessary.
Periodic Visual Cable Checks
Solar doctor will check cable runs particularly outdoor runs to ensure there are no stresses, weaknesses, wear, insulation breakdown, damage caused by vermin or sunlight. This ensures there is no safety issues as well as yield losses.
Periodic Electrical Maintenance
Solar doctor will ensure that Electrical connections are checked annually for tightness, corrosion and to ensure there are no scorch, electrical burning marks or smells. Electrical containment will be visually checked and tightened. Electrical Over current protection devices will be checked for tightness, operations and test buttons operated. Electrical maintenance will be completed annually.
Preventive Maintenance
O & M tasks such as electrical condition reports, visual cable checks, mechanical maintenance, electrical maintenance, panel cleaning, inverter display checks and monthly reports and logging all help reveal problems or potential issues. If issues are found corrections will be made to further prevent maintenance.
Corrective Maintenance
If a fault is determined via the remote monitoring or via a report. Solar doctor will respond within 48 hours under the O & M agreement. If possible Solar doctor will make every effort to fix the issue on their first visit however if it is determined to be an equipment issue we will order parts and replace as soon as possible.
Periodic Solar Panel Cleaning
Solar doctor propose to clean the surface of the solar photovoltaic modules annually. Accumulated dirt on the surface on the modules could reduce the output of the solar photovoltaic array in a similar way as shading would. Solar doctor believe this could reduce the performance up to 5%. In some circumstances, we may recommend additional cleaning; this will be charged at an extra cost.
Annual System Reports & File Logging
Solar doctor will send an annual report to a nominated person. This will include monitoring logs, reports of any system defaults with explanation of rectification, any completed maintenance documents and certificates.
Periodic Inverter Display Check
Solar doctor will check annually that the inverters are free from dust, operating at normal temperature and we will ensure that there are no errors displayed on the inverter log. Doctor Solar will monitor the inverter daily using remote monitoring. If it is found that the inverter is not performing correctly, corrective maintenance will be exercised.
