Powering 250 watts 24/7 |

If I am reading this correctly you will need 200 watts 24/7 just |
|
to run the refrigerator. To get this done you will need four 24 |
|
v solar panels and a Gull 160 VAWT. On a sunny windy day you |
|
will be putting 400-500 watts into the battery bank. On a |
|
cloudy windless day you will be getting about 60 watts. On a |
|
cloudy windy day - 160 watts. At night - 2-150 watts depending |
|
on wind. For periods of dark and no wind the batteries will |
|
supply the power. |
|
A good deep cycle battery will give you about 50 amphours. |
|
Since you need about 10 amps, that's just five hours of backup. |
|
So you need to have enough batteries in parallel to get that to |
|
about 20 hours. |
|
That means you need eight 12 volts in a configuration to give |
|
you 24 volts, 2 across, 4 parallel. |
|
The lighting and small appliances don't take much power so that |
|
is your easy luxury on weeks where sun and wind are plentiful. |
|
You would only need to watch your power during extended periods |
|
of cloudy windless days. |
|
I have two 150 watt panels that actually put out 135 watts in |
|
typical conditions. I could get closer to the 150 watts if the |
|
positioning was dead on perfect alignment. |
|
You might be able to bring the cost down on this install if you |
|
search for deals on solar, find used batteries and pulse charge |
|
them back to life, and ask me for a discount on the Gull 160. |

I just got the seagull75 plans. I live in the NW Oregon Coast |
|
Range, wind power will be moderate to good, solar will be good |
|
for 6-8 months most days, winter is Rain! I have a creek with |
|
year round flow and about a 300 ft drop on my place, I am |
|
planning on using your radial alt design and incorporating that |
|
unit micro hydro, wind and solar, I am also going to work on a |
|
steam generator capable of 10 hp or so, so I can have power to |
|
run wood production machinery. (We have a tree farm with lots of |
|
timber). We already hear with wood, just need to get the |
|
electrical power generation going. I like the idea of point of |
|
use power for lighting and modular mini "grid" set up on the |
|
home place, utilizing multiple sources of power for |
|
redundancy(the aircraft maintenance background coming through |
|
there). Do you have plans for the 160 wind plant? Or is it only |
|
available in purchased completed form? What region of the |
|
country are you located? Your videos are awesome, and I really |
|
appreciate all the effort you have put in to put your |
|
information and results out there for others!! |
