1 How many main types of clouds are there?

diffuse irradiance
2 Can clouds increase solar irradiance reaching a photovoltaic?
Yes, but they have the disadvantage.

3 Do solar towers that produce energy from the sun work at night?

No, because need direct irradiance.

4 Which of the three (or combination of) types of solar irradiance do photovoltaics use?
three.
5 Which one the countries below has the highest solar irradiance potential?
In Germany.

6 Is solar energy the solution?
Yes but have advantage and disadvantage
7 Should more focus be given to better and cheaper batteries to store energy for household use?
Yes, because this is cheaper and care the nature

8 If satellite imaging was open-data, and anyone could access it, would that increase the use of solar energy systems?

Yes.

9 How would the world, as we know it, change, if free energy

The world would be better because not occupy an expense and would not affect the economy of people
