Maintaining solar system for maximum power production

Periodic maintenance is very essential for the maximum utilisation of solar power system. Ideal choice would be to get it checked by a CEC accredited electrician. They will check the installation, identify the issues and rectify it. We have to give first-hand information to the technicians regarding the issues to help them diagnose the problem. They will inspect all the components and make sure it is functional and well maintained. Solar panels have to be washed once in every 6 months to keep it clean. Load shifting has to be practised for optimising power consumption.

Periodic maintenance of solar power system is essential for its smooth functioning and excellent performance. Ideal choice would be to get it checked by a CEC accredited electrician. They will check the installation, identify the issues and rectify it.

We have to give first-hand information to the technician about our solar system, to help them diagnose the problem. The most common issues cited are:

               Issues                 Reasons
1. Inverter switching off and trying to restart during the day. 1.can be due to faulty meter, grid tolerance parameter is set too low or grid voltage is set too high
2. Isolator is burned out and export to grid is falling down. 2. Can be due to poorly terminated or polarised cable.
3. Panels failing to go into open circuit. 3. can be due to diode failure
4. Inverter failing to start in summer. 4.can be due to hot temperature

Survey of 2016 highlights module, inverter and installation issues as the major faults mentioned by users. Technicians inspect all the components of solar system and perform a range of tests to check its efficacy. Most commonly conducted tests are:

  • Inverter live and dead tests
  • VOC checks
  • ISC checks

To get the benefits of solar energy, we have to safeguard the solar panels from dust and soil. Otherwise performance will be affected. Washing the panels is guaranteed during electrical health check. Panels have to be washed once in 6 months to remove volatile soiling. There are solar panel companies that recommend washing the panels every 3 months. It is a waste of money, unless and until there is a valid reason. Always get an expert opinion before getting it done.

Load shifting has to be practised to optimise power consumption. Solar panels produce maximum when exposed to sun. The peak hours of solar exposure is from 10 am to 4pm. Hence we have to see to it that electrically intense devices have to be used during daytime, thus consuming what is being produced by our solar system. If we use these gadgets after peak solar production time, we need to take power from the grid at peak rates. If we are not at home during daytime, it will be a good idea to set timings for washing machine, dishwasher an even air conditioner, so that most of the energy is consumed from what is being produced.

Well maintained solar panels helps you to make the maximum out of your solar power system, thereby making a huge monetary benefit.
