Hello.

During the summer 2012 Francophone Meetings, I was asked : “What do you need to electrify a house for 24 hours ?“

After a few personal research, here is the answer I gave that day.

Hello Eliphas.

During the summer 2012 Francophone Meetings, you asked me what would it need to electrify a house for 24 hours ?

If you have 4 x 12V batteries, each with a capacity of 100 Ah, then it’s possible.

(connected in series = 48V x 100 Ah = 4800 watts for a discharge  <50%).

1 x AGM 12V x 100 Ah buy Xenical online battery = 270 euros

So for a house, it makes 270 euros x 4 = 1080 euros

Another trick, 2 x 12V 200Ah batteries (which gives 4800 watts in the end too).

Order Disulfiram 1 x AGM 12V x 200 Ah battery = 480 euros cheap Valtrex

So for a house, it makes 480 euros x 2 = 960 euros

Last trick, take 3 x AGM 6V x 240 Ah batteries, they cost 280 euros each. It then makes 840 euros for 4320 watts of storage…

Only catch, you need to add a pure sine (sinusoïdal) wave convertor to get an output of 220V. And it costs 800 euros to connect 1500 watts on it.

(possibility to find at half price on Ebay)

Hello.

I am pleased to announce that the 150 watt electric terminal has been tested in real conditions at the summer 2012 Francophone Meetings.

First of all, let’s recall what it consists of :

• A GoalZero Boulder 30 monocristallin photovoltaic panel
• An ‘all-in one’ GoalZero Escape 150 regulator/battery/converter

Depression

• + a cable converting 8 mm to 4,70 mm

Here is the first picture :

During the summer 2012 Francophone Meetings, there was a water-heater. We therefore connected the 220V pump on the electric terminal.

With more than 1.400 rpm, the consumption is 33 watts. This allowed the pump to function many hours.

In conclusion : with a full electric terminal (150 watts), it is possible to function the pump of the water-heater for many hours. Knowing that it’s primarily connected to the showers, it’s great to have some hot water 🙂

Above (photo 2), you can see the back of the installation. The 30 watt solar panel is connected to the terminal (entry 4,70 mm). The terminal has a 220 V outlet on which the pump was plugged in.

Above (photo 4), the 150 watt electric terminal on the morning of Sunday July the 29th, 2012 where we had the chance to have a lot of sun.

The terminal charged slower than I imagined. But it still functioned.

Above (photo 5), you can see another side view. With a handle, the terminal is convenient to put the solar panel on. It doesn’t take too much space and is easily transportable.

On this picture (photo 7), you can see the 150 watt electric terminal charging a GPS buy Tadalafil  (the small dial you see on top of the photovoltaic panel).

After a nice weekend in the countryside, the panel got dirty. Above (photo 8), you can see the condition of the cloth after wipping the panel (the cleaner the panel, the more electricity transfer per hour is great).

On Monday July the 30th, 2012, we had rain. Therefore, the panel was moved places.

On the above picture (photo 9), the panel is simply laid against the wall of the barn (with a small roof). That way, the terminal is protected from rain and the solar panel can still capture ambiant light.

Obviously, in this setting, the amount of watts per hour transfered is less important. But the goal here is to generate a (quasi) continuous source of free energy to charge the terminal (battery) to the maximum.

In general, tests in real conditions were a success. Two things to remember :

• Always (re)position the photovoltaïc panel to face the sun
• The battery charges slowly. A second day of exposition is therefore necessary if we want to charge the battery to the  maximum (150 watts).
