Ah would you stop. How the fuck would it generate all the electricity in his house. These yokes can hardy heat water to 60 degrees, how would they power an oven to 500?
Apologies, it was ā¬6000 before VAT not ā¬4000. I believe you also get a grant off the VAT amount. So ā¬6000 paid for ā¬6800 value. He reckons theyāll have generated enough energy to justify the investment in 5/6 years.
He generated 80KWH in a week just after he installed them and I would assume that heās running a much more energy efficient house than me. Iāll estimate 20% more efficient. Could be more. So my last bill was for 995 KWH for 2 months. Less 20% would be ~800KWH. 80KWH * 9 weeks in 720KWH. So itās close enough.
That would work out to be a 2 month electricity bill of 80KWH which would be ā¬15-ā¬20.
How does it power the house? Usually solar panels are linked to an element in the boiler and just heats the water up to say 60C, then an immersion tops it up. Is this connected to a battery array that the power sockets are run off?
Weāve had solar hot water for a few years now and it has led to a serious reduction in electricity bills.
2 months ago we installed a solar array on the roof of 8 panels. Itās the middle of winter here (or what we laughingly refer to as winter) so daylight hours are shorter obviously. But yesterday as an example, a three person house, we consumed 11.528kwh. We generated 9.532Kwh from the solar panels (excluding the hot water).
Generation during the day (obviously) so during that period of solar production, we produced 9.532kwh, consumed 3.873kwh and exported (or sold to the grid) 5.659kwh. We bought from the grid (during off peak when solar production wasnāt happening) 7.655kwh. Thatās one day as an example (we have an app that tracks all the production and consumption in real time). So basically, during winter, we have reduced our reliance on grid electricity by about 70%. From spring onwards, Iād expect us to be a net exporter of energy to the grid. Subsidies have been severely reduced here, so the amount weāre getting from the grid is negligible (about 6cents / kilowatt hour), but the reduction in power bills will be enormous. The whole array will have paid for itself in 5 years (we have it financed through the energy company for 7 years). And weāre generating renewable energy.
We havenāt looked at a battery yet, but will in a couple of years time when itās clearer whatās available and what the prices will be. Apart from the financial and environmental benefits, this would be insurance against the inevitable power outages that will result from the complete clusterfuck that is energy policy in Australia.
Also, last year, we had 9 power outages resulting from storms / trees falling on power lines etc. No power for three days in one case, fucking joke. The grid is dying and the whole bollocks baseload electricity argument with it. More and more companies here are investing in their own energy sources. Telstra, which consumes 1% of Australiaās electricity output, recently invested $100 million in a solar plant to hedge against rising power costs.
Guys. How far are we from a viable electric vehicle solution for those that donāt have off street parking? From my research to date, in the absence of being able to plug in at home, Iād need a charging point in work at a minimum. Hardly ideal though. Can you lobby ESB to install a charger on your road?
You need to keep the current crop of users on board though to stop this becoming a monorail. I know of someone whose charging cable was nicked at a Northside dart station lately.
