Frequently Asked Questions

Installing a solar photovoltaic (PV) system at your home or business is a great way to slash your power bill and get back control of your electricity usage.

The best way of determining your solar system production is by checking the readings on the display of your inverter. You should monitor the readings over a 7 to 14 day period for best results. If you are concerned that these reads are lower than expected please send the filled out Solar Generation Log into our office for assessment.

If the voltage is too low (during sunset or sunrise) the inverter will shut down until the DC input voltage is sufficiently high enough to register again. Some inverters will indicate ‘voltage low’ with a flashing light prior to going into ‘sleep mode’.

During a ‘blackout’ or power cut, all grid connected solar inverters will automatically shut down. This is a legal requirement as a safety precaution, due to the possibility of utility repairs being conducted and the workers potentially touching live wires that are still receiving electrical currents from solar installations. Once the power is back on, you should always check that your inverter has started up normally.

From time to time a disturbance in the electricity grid, caused by a voltage spike, can cause your inverter to shut down or go into ‘fault mode’ in order to protect your property and the inverter. It is advised to refer to the inverter operating manual and also try restarting your system manually following the ‘shut down and start up procedure’. It is recommended that you then monitor your system, as generally it will correct itself. If your inverter continues to display an error message, please contact Goodhew and we will be happy to help resolve the issue.

Although the rain removes some dirt and dust, depending on the environment that you live, it is recommended that you clean your solar panels at least twice a year to enable optimum production. If you experience a lot of dust and debris or salt spray, you may wish to clean the panels more frequently. A soft cloth, soft brush or even a soft mop for heavily soiled panels can be used with very mild dish washing detergent if necessary. You should ensure you rinse the panels thoroughly and NEVER stand on them. Goodhew offers a full maintenance and panel cleaning service.

There are a number of factors to consider

  1. You should check how many kilowatt hours (kWh) you have used in the past compared with now, using previous and current bills. Your ‘average daily usage’ in kWh should be on the front of your electricity bill. If you have been using more power than normal or your retailer has increased their charges, you will pay more when your electricity bill arrives.
  2. The solar credits (as outlined on your electricity bill) indicate the money you have been paid for solar power in kWh that you have NOT used and effectively sent back to the electricity grid. Those figures are not what your solar system has produced in total for that billing cycle. The only way of determining your solar system production is by checking the readings on the display screen of your inverter.
  3. To use your solar system efficiently and see greater savings, you should not increase your energy consumption but change your energy consumption habits and try to use your electricity throughout the day when the solar power is indicating peak production (10am-3pm on clear sunny days).
  4. As recommended, you should monitor your system regularly by checking the solar inverter. The sooner you notice anything unusual or if there is a fault light or message on the display the sooner the issue can be addressed.
