Living off grid has advantages, like no huge electricity bills, but we need more solar panels and a bigger battery bank because sometimes a girl just wants to run her hair dryer without having to
put on the generator!
These four tiny solar panels suffice in summer but in winter I wonder if the lights will stay on until we have finished eating or will we get to the end of a DVD before the inverter starts to sing telling us the power has run out. It takes a few days in winter for the solar battery bank to build up again, so we listen to the generator thumping along in the background; the country serenity gone!
You can imagine my excitement when hubby arrived at the
farm with 8 x 60 volt humungous solar panels he had bought cheaply
from a house demolition sale. Oh
joy!! I may not have to go to bed at
7.30 pm through lack of power. I may be
able to run a few of those modern power hungry conveniences, most with elements
that everyone on mains electricity take
for granted but here they zap away our solar power - toaster, kettle, electric frypan, vacuum, HAIR DRYER!!!! Really all I want is my hair dryer....and
maybe my beauty therapist wax pot. A
microwave would be good but I can live without one.
The gloriously large panels went up on the roof. Husband had taken detailed notes of how the panels were connected on the roof he had removed them from, copying the layout exactly onto our roof. He connected them up to a controller he had purchased ages ago.
The following day was clear, the panels thirstily sucking in the sun’s energy.

All of a sudden there was smoke billowing from the side
of the house! The controller was on fire.
Just as well we weren’t off working in a paddock; the whole cottage
would have burnt down.
The panels were quickly disconnected and covered over just in case we were so stupidly clever with their assembly they continued to suck in the sun juice.
It seems the controller was far too small for the amount of super doper juicy energy flowing through it as the panels were set up in series. No, no, no!!! Series is only in a grid situation feeding back into the mains power supply! We were putting 480 volts into a 12 volt controller! No wonder it had a heart attack and began to burn.

Husband raced off into town to find someone
to advise us while I stood sentinel over the failed project in case the house
went up in a puff of smoke.

A solar expert from town came out to have a look at the
set up and tell us what we needed to make the little cottage run completely on solar power, including running an electric refrigerator instead of our gas one, so my little cottage would be just like an ordinary
house on mains electricity.
The list was longer than any child’s wish list for Santa but nowhere near as interesting to read. Cables, fuses, larger inverter, plugs,
chargers, breakers, flex, conduit, switch board enclosure, larger inverter, insulated
battery box and more deep cycle wet batteries.
So our cheap solar panels look like costing us somewhere
in the vicinity of $10,000 upwards depending upon the size of inverter and
amount of batteries needed.
My dream of milking the sun and running my hairdryer without the generator
has been dashed again. The gleaming large solar panels remain decoration on the roof for the moment.
Hmmm......Yep too much sun juice.
