Our quality 1kilowatt system can generate 4 to 6 kilowatts of electricity per day and save an estimated 32 tonnes of carbon emissions, during the 25 year warranty period of solar panel output.

Re: To solar power or not to solar power, thatīs the question
OK, my bill says I pay 13.567 cents per kW for my power. Assuming this generates 4kW per day then that's 13.657 x 4 = 54.268 cents per day saved.
365 days in a year gives $198.0782 per year saved
You pay $3,975 for the panel to save $198 per year, it will pay for itself in about 20 years.

You don't use 13.3kW per day. You use 13.3 kWh. That is the same as using a constant draw of 1kW for 13.3 hours.

A 1kW system has a peak power output of 1kW. ie. During the middle of the day when the sun is at the optimum angle. At night, its output is zero. At other times of day, it's somewhere in between. As Vlad indicated, you'll get 4-6kWh cumulative output per day.
You won't use all of that, because you use power when you use it, not when the system is ready to give you some. But if it's connected to the grid, you can sell your unused power back to the electricity company. e.g. On a weekday, when no-one's home, your solar system can help power the air conditioning systems of office blocks. (Very small help. ) The sell price per kWh is, I think, usually higher than what they charge you per kWh. So you should get your money back a bit quicker than Glen's estimated 20 years, but it will still be a long time.

Bugger! What a disappointing outcome. And mind you, the prices mentioned are after the government rebate, ca. $8000.00. You would have to be a very fanatic treehugger to install this.

Seriously, if it was that good, commercial nature would take over.
It does not. More research will be done, I am sure. Give it 20-50 years.
I will be dead by then. In hell, I think... as a stuff member
