Sun Speed it can gain by

1.Hero Skill

There are 2 types of Hero Skill that can gain Sun Speed

1.1.Increase Sunlight

Sunlight Increase is Depends on the level of hero and equipment or Talent.

1.2.Increase Building (Times)

Building it depends on level of the building.

There are 4 Types of Building and SunLight Hero skill

1.Beginner(Green Border)

2.Junior(Blue Border)

3.Senior(Purple Burder)

4.Specialist(Red or Orange)

Red and Orange same Specialist

Orange

Red

Reminder

1.If purple to red(it means evolve purple to red) it can only be Senior Skills

2.But there is a big gap between the 2 and also a Hero Level can be determin to Sun Speed

Example of Gap on between Senior Increase Sunligh and Specialist in the same level  

Purple to Red

Orange to Red

This Two is so big different Gap % between Senior and Specialist.

3.Equipment and title can also get a Sun speed

4.Sending a ❤on Friends is temporarily added on Sun Speed but maximun of 10%

(It means Everyday you need a ❤ 10x)

5.All Titles that have a expiration date is also added on sun speed.

6.changing the equipment or high level skills of hero plants will decrease your sun speed.

Example:your current hero plant is high level skill with orange and then you have also equipment with high attributes like red equipment.then you switch his equipment to red hero plants with low level skill so it will decrease your sun speed.

(If the title is expire the sun speed is also decrease same with sending a heart from your friends)

I don't know what is a Max Level of Skills but i can say the more a level of skills and the more a higher gives or a massive added Sun Speed.
