solar panels

Eatch panel is 350w
4 panels=1400w but the turnover isn't just 1400 unless we have an overcast and rain From 10 am to 2 pm it's well over 2000w
It's beond me why a small investment of say 50,000 thb
should hold back any expat from being free of power outs (witch occurs so often that it makes it difficult to maintain a wifi connection)
THATS the real benefit of solar power, not the 1000 thb you save every month.
