Good video. Thanks for uploading. Gives people an idea of what they can expect with these units. Just be mindful of radio interference generated when they are operating. Place an AM or shortwave radio nearby and you will see what I mean. You are right about recouping the cost of the panels. It would take many tens of years for the miniscule power bill savings to recoup the panel costs.
But it’s interesting and all good fun… Mods for radio interference:

@sparktastic1 The AM radio thing is very interesting I would never have thought of that. The panels have been running about a month now and generating 1kwh a day which I did not expect from 2x80w panels. So I have decided it would be a good idea to get some more panels as they only need to generate about 12-15kwh a day to fully power my house. And nice website very interesting I have been looking at the PowerJack inverters on eBay and that is probably what I would use.

@aljisonline You are producing excellent Kwh figures for only 160w of panels. Trouble with this stuff is that it can become a little addictive. I started off with only one 60w panel. Now, a few months later I have 600w of panels on my roof and more coming. The great thing about the 300w inverters is you just buy another each time you add more panels. I wouldn’t be running much more than your 160w into each 300w inverter anyway as it will only overheat and your conversion efficiency will suffer.

@sparktastic1 You should make a video of your solar panels and I have bought an inverter now but it has to come from Germany it’s not the powerjack one but I have also decided to put a small wind turbine up for this I have decided to use a powerjack inverter as I don’t want to spend so much on it. I shall see what happens and hopefully get some more videos of it all.

@aljisonline Will try and post some more videos in the next week or so. I purchased the PowerJack 1200w GTI, but it only lasted about half an hour on the test bench, then it blew up! I wasn’t even putting much power through it. Anyway I don’t know about the UK, but ‘down under’ the price of electricity is going up by 65% over the next two years! We currently pay about 21c or about 12.5p per Kwh.
Everytime the price goes up I/We save more money on our bill by using these GTI’s.

@aljisonline I have standard solar panels at work that have been in service since 1985 and they still put out at least 95% of what they did when they were first installed. What other equipment can offer 25-30 years of maintenance free, useful life like that? The way I look at it, the price of electricity will keep rising and I will never not want to reduce my power bills, so I think these things are a good investment no matter how long it takes to pay the gear off.

is the grid tie inverter wired up straight from the panels or have you got some battery’s

An interesting (and low cost) demo of this can be done with a small electric motor out of a toy (or can buy at Radio Shack) and a small 1.2 volt flashlite bulb.
Attach the bulb to the wires on the motor. Put a fan/propeller cut from cardboard (or my favorite was the prop from a balsa rubber band airplane) on the motor shaft. Blow on the propeller. The bulb will light. In power stations they substitute steam, water, wind, burning gases for your breath, but it’s doing the same thing!
