Do solar panels work at night? [UK, 2026]
We explore whether solar panels actually produce any electricity at night, how you can make the most of your solar panels after sunset, and an exciting new technology on the horizon.
What happens at night if you have solar panels? At night, solar panels stop producing electricity because they rely on daylight. However, if you have a solar battery, it can store excess electricity generated during the day, allowing you to use it at night. Otherwise, your home will draw power from the grid to meet your night-time energy needs.
No, standard solar panels don't produce electricity during the night since they require sunlight to do that but new technology such as anti-solar panels and radiative cooling PV cells, can generate a little bit of power in the dark by converting radiation from heat into electricity. Solar power is one of the most renewable sources of energy.
As we've established, solar panels can only generate electricity when there's daylight. However, you can still use your solar panels' electricity after sunset - just add a storage battery.
They rely on natural light to generate electricity, so they only work in the daytime. As a result, if you plan to make maximum use of your solar panels (and you don't have a battery), it's wise to shift most of your electricity usage to daylight hours.
