MYTH: “SOLAR PANELS ARE NOT WORTH THE COST BECAUSE THEY DON’T WORK WHEN IT’S CLOUDY OR AT NIGHT.”
Fact: Solar power works even in cold or cloudy places, and new tools are allowing us to use it even when the sun goes down!
Because of the way the technology works, solar panels are just as effective—andusually more effective— in cooler temperatures as in hot ones.
And while it’s true that clouds can affect the efficiency of solar panels, they can still produce enough power to be viable sources of electricity. Germany, for example, is a country that is not particularly warm or sunny, but is nevertheless the world leader in solar energy, generating more electricity with solar than nuclear powerin July 2015.

Innovations in managing the grid and new energy storage technologies are helping make renewable energy more reliable all the time, including when the sun isn’t shining and at night. With larger, more integrated grids, better resource forecasting, innovative combinations of renewable technologies, and advanced energy management systems (like smart grids), we now have more tools available to make variable renewable energy technologies like solar more reliable than ever. At the same time, new energy storage devices like Tesla’s Powerwall and Powerpack batteries — which can be used to store electricity when solar panels aren’t generating energy — are starting to change the way we think about the timing of electricity production altogether.
In summary, as more renewable energy is added to the grid, it gives us clean electricity, diversifies our energy mix, and can even help bring quick and affordable power to areas that fossil fuels and traditional grids may not easily reach. In addition, innovations and new tools are allowing us to use more solar in our energy systems than ever before.
