FREQUENTLY ASKED QUESTIONS
When can I turn on my Solar Roof?
You can turn on your Solar Roof after you have received permission from your utility company or from
Tesla Customer Care .
How much energy does my Solar Roof produce?
The amount of energy your Solar Roof produces depends on your system size, as well as environmental
factors such as shade, dust, debris, snow, and weather. Refer to your Solar Roof layout document for more
information.
Can I see how much solar energy my home is generating and using?
The Tesla app gives you real-time and historical visibility into your solar production and home energy usage. Use
the Tesla mobile app to follow your energy production in real time.
How long can I expect my Solar Roof to last?
The solar array electrical components of your Solar Roof have a 25-year operating life. Your inverter and
Mid-Circuit Interrupter (MCI) have a 10-year warranty from manufacturer and may need to be replaced after that
period. If you have a Powerwall, it has a 10-year warranty and may need to be replaced after that period. Please
see your contract for additional information about the other components of your Solar Roof system.
Will I still be subject to electric rate increases if I buy Tesla Solar Roof?
Even with solar, you will most likely have a residual utility bill and those rates may fluctuate. The bill depends on
the size of your Solar Roof system relative to your energy demand, as well as your peak hour energy use. You
can minimize utility rate changes by using less energy during peak hours.
What happens when the sun goes down?
You automatically draw power from the utility grid. Since you are always connected to the grid, your home is
fully powered at all times. You never have to worry about “running out” of energy. If you also have a Powerwall
installed, some or all of your energy needs are supported by it.
What happens to my solar production on a cloudy day?
Your Solar Roof can still generate electricity on cloudy days, since even diffuse sunlight can activate solar power
production. Solar Roof output on a cloudy day may be less than on a cloudless day, but still often produces a
meaningful amount of electricity.
Will Tesla Solar Roof impact heat transfer to the attic?
Tesla Solar Roof is designed to encourage airflow underneath the solar tiles and ventilate hot air through a
ventilated ridge cap.
