Shaykh Abdul Hameed Al Hajooree in his book الذهب المسبوك في احكام الكسوف, page 52-53, mentions,

“Matter:

Does praying the eclipse prayer alone count, or is the congregation a condition for it?

Abu Yousuf and Muhammad Ibn Al Hassan from the Hanafis went towards this statement (that the congregation is a condition).

Speech regarding having the congregation for the eclipse prayer has preceded and we came to a conclusion that the congregation for it is better and more complete.

The one who isn’t able to pray in congregation, whether that be a man or woman, then it is obligatory upon them to pray even if it be alone, or a man praying with his family.

Our proof for that is the narrations which preceded in the chapter ‘The actions in the eclipse prayer’ are [such as]

‘If you see that (the eclipse) then pray’

Ibn Qudaamah said in Al Mughni, 2/142,

‘It is legislated/Sunnah to pray it in congregation or alone, and with this Maalik and Ash Shafiee said'” End translation.
