MYTH: Solar can only ever make a small contribution to our energy needs because it doesn’t produce power at night. Solar panels do not generate power at night. Once the sun goes down, your home or business will start to draw power from the main grid as usual.
FACT: Solar panels still work on a cloudy day; however they will not generate as much electricity as when the weather is clear and sunny. For systems that include a battery backup, the inverter regulates the charging of batteries during the day. The electricity stored in those batteries can then be used at night.
Today, homeowners with solar PV systems don’t just have to sit in the dark. We’ve got options, starting with storing solar electricity for later use. With solar prices constantly dropping and utility prices increasing, adding batteries to your solar installation is becoming a reality. Check out the sleek Tesla Powerwall battery backup. These beauties undergo extensive testing to ensure they can withstand extreme weather conditions, including heavy snowfall and hurricane-force winds.
