No - standard photovoltaic (PV) solar panels do not generate useful electricity at night because they require photons from sunlight (solar irradiance) to free electrons and create current.
To calculate the number of solar panels your home needs, divide your home's annual energy usage, which is measured in kilowatt-hours (kWh), by your local production ratio.
All in all, the short answer is no - panels generate no electricity at night. However, this doesn't mean your smart home will be left in the dark when the sun goes down.
Mono panels generate electricity from sunlight through "the photovoltaic effect". This effect occurs when the high-purity silicon semiconductor within the cells of the panel produces a direct current in response to light.
You can make money from solar power by selling excess electricity back to the grid through net metering, earning solar renewable energy certificates (SRECs), leasing your rooftop to solar companies, and investing in or developing solar farms.
In the United States, 14,626 MW of PV was installed in 2016, a 95% increase over 2015 (7,493 MW). During 2016, 22 states added at least 100 MW of capacity. Just 4,751 MW of PV installations were completed in 2013. The U.S. had approximately 440 MW of off-grid photovoltaics as of the end of 2010. Through the end of 2005, a majority of photovoltaics in the United States was off-grid.
