System Performance and Maintenance

System Performance

Your solar system performance is measured by how much energy is generated over time. Energy production can vary from month to month based on seasonal weather conditions. Other factors that can hinder production include:
  • Unexpected shading due to new tree growth
  • Debris or dirt on the panels
  • Long periods of cloudy, rainy, or snowy weather

You can find expected performance information on your solar panel layout document. You can also use the Tesla mobile app to follow your energy production in real time.

System Maintenance

Solar panels require routine maintenance. Minor care on your part can ensure better system performance.
  • Shade on your solar panels can hinder electricity production. Keep trees or other tall plants trimmed to prevent shade on your solar panels.
  • Cleaning your panels to remove accumulated dust, pollen, and leaves maintains system performance. The required frequency of cleaning depends on where you live. Ordinarily, you can rinse off panels with a water hose from ground level to remove accumulations.

DANGER
Rinse only the glass cover of the panels; do not rinse wiring or areas underneath panels.

DANGER
Do not walk on the roof without being trained and using required safety equipment. Walking on a roof is a fall hazard and can result in serious injury or death.

CAUTION
For safety and performance reasons, do not walk on your solar panels. Solar panels are fragile and can crack if stepped on; they are also slippery when wet or dusty.

CAUTION
For safety and performance reasons, rinse panels only when the sky is overcast, or when the sun is low in the sky, as panels can become hot under intense sunshine.

If you have excessive soiling, such as bird droppings, you may wish to hire a local solar panel cleaning service.

CAUTION
Do not shovel snow off your solar panels. While accumulated snowfall can cover panels and temporarily reduce production, this is not a cause for concern. Your system is designed with annual energy production in mind, and occasional inclement weather is expected.
