Not directly. That electricity is converted to heat when it's used: All devices are space heaters, some just do other things as well. Even if not used, it would still be converted to heat by the panels. There's no getting around the conservation of energy.
In theory, we could send that power out into space as microwaves or light, but in practice the effect would be negligible. The direct heat output of every human activity is nothing compared to the sun: All the electricity generated on earth is around 3 Terrawatts, while the sun hits us with 200 Pettawatts, 66 thousand times more.
On the other hand, burning fuels releases gasses like CO2, which can traps sunlight and creates thousands of times more heat than the actual amount of power generated. If we stopped burning fuel, it would stop the current massive increase in global temperature, which would then slowly be reversed by things like the carbonate-silicate cycle.
Perhaps feed the convincing fake data so they don't realize they've been IP banned/used agent filtered.
