Off the grid Solar solution

[Jeroentune]

Hello All ,

our plans are getting a little more real and we bought some lot in Asia, Philippines.
Our plan is to built a wooden cabin 27 x 40 feet. it will be a A frame house.
I have the idea to built a rack with solar panels. I dont want to have the panels on the roof since the angle is too steep and weight might be an issue.
we will not have heating systems ore airco , but we do need enough for a small fridge, laptops, small sound system and electric fans.(2) I like to built an off the grid system.
Beside solar panels i have the idea to add 2 ore 3 smal windmills since there is always wind in that area. the system need to include a battery setup for the nights.
can a pro like you advise me in the ammount of whatss , amps and panels and so on ?

First, you need to tightly define your loads. Otherwise you risk:

Overbuilding a system and wasting a lot of money you didn't need to spend.
Underbuilding, and loosing power at 9pm at night and your batteries die and need to be replaced.

Some folks are fine with a 500w system, but my wife would not accept the restrictions that imposes, so we're at 5Kw of panels..


Windmills seem sexy and all, but without being way tall and above local obstructions, they get turbulent wind and
can't really produce power. If you have enough wind that your hat blows off your head, you may have enough to
look further into wind.
Wind turbines need regular maintenance, oil & grease on the moving parts. That means your either tilt the tower down to the ground, or you climb up to the top to do the work.
