Dear fellow professional Audio players,
I am totally beginner and got no clue at all but i would like to build a outdoor solar powered speaker.
this system is to help me repel monkey in my coconut farm.
A speaker system function :
1. solar powered
2. 4 direction low watt speakers (i got no idea which type of speaker to choose) - is there any weather proof speaker?
3. sd card enabled board/amplifier i believe, so i can store fireworks sounds/ snake hissing sounds/ some other loud sounds which are repeated
4. this system will have a 18650 battery that can last about 24 hours
so i need to know what kind of board/speaker/solar panel watts/ how man 18650 battery do i need to power up this outdoor speaker.
can someone help me on this build?

I think monkeys are intelligent enough to find out that the speakers are artificial, since snakes cannot make fireworks' sounds etc. Once they find out that these are harmless, they'd simply dismantle them !!

@hal4287 has experience with solar-powered electronics that have to work outdoors continuously, but in his case it was for monitoring migrating birds - it didn't make but analyse sound. https://www.diyaudio.com/community/threads/need-advice-for-a-weird-project.352655/post-6159052
For Higher sound Pressure and efficiency
Use PA Paging Horns.
Many Hobbyist are building portable music players.
So pre designed 18650 Battery Management systems
are available
Another possibility is using Solar powered shed
lights as power system.
Actual explosions may be more effective.
Numerous Cannons have used cartridges
similar to .22 or shotgun shells.
But likely for multiple timed explosions
and availability of cannon charges.
Much easier to use propane cannon
Something everyone should own for
business and fun 😀

It's a pity there are no primate ethologists on this forum, as far as I know.
Anyway, if you can't scare them, maybe you can annoy them sufficiently. At least that works well with humans (the only primates living over here outside zoos), and with mice.

Make the sounds obnoxious enough, and come by surprise. That may be enough to startle and annoy sufficiently. Sirens, Metallica, somebody screaming into the mic….. Random intervals.
You may have to use proximity sensors to trigger the gunshot / fireworks sounds in order to convince the monkey that the threat is indeed real and living. And just imagine the number of repellant setups and the sound pressure levels needed to cover the entire area of a coconut farm. Even so, they would eventually get accustomed to / learn to circumvent these arrangements, just like the lab rats (that have much smaller brains) manage to do.
In my opinion, only a reptile can be fooled that easily.

I wonder what people would do if they stepped on my property
and a propane cannon went off
Pretty well known monkeys are afraid of loud bangs and snakes

The sound repellent concept might work. I say so because I remember our local zoo had a howler monkey exhibit with 20 or so monkeys. For the most part the monkeys were fairly quiet but several times a day the zoo keeper would stop by with a portable tape recorder and play a recording of monkeys screaming and howling. This was enough to start a massive howling frenzy which went on long after the recording stopped. Not sure what the subject of the recorded howling was but it worked every time, and the monkeys never seemed to get used to it. So with the right sounds maybe they will just stay away as you intend.

"Thailand has been raising and training pigtailed macaques to pick coconuts for around 400 years. Coconut farmers in Sri Lanka, Malaysia, India and other countries in the region sometimes rely on monkeys, too."

Here in India, there's no need for monkeys to cut coconuts, as we have developed the following: 👍
