Photovoltaic electricity

Post by mike strand2 » Sun Jun 23, 2019 10:06 pm

I'd be interested to hear from other Forum members who have installed photovoltaic panels.

I have received 2 quotes for a 3KW system comprising 11 panels. Specifications appear similar. What concerns me is the massive difference in the cost; One is €3,080 more than the other!

I had a 5kw system fitted in February. I went for a system that allows you to generate electricity, even when one or more panels are in shadow. It is rare to have all panels perfectly positioned, with no shadows from chimneys, trees or even birds. They are known as “Power Optimisers” that effectively turn a system linked in series, into a parallel circuit.

The system Jimgward refers to is more expensive than the cheapest options available, however it produces better results. So prices for a 3KW system can vary depending on what sort of system you are getting.

Our system is the cheaper variety, but our panels are on the ground, rather than on a rooftop, as we had sufficient space. Even so, I have to ensure that hedges are trimmed so that no shadows are cast over the panels. And if I deliberately wave my arm over the panels, to create s small shadow, you can see a significant drop in electricity production.

We have had a 3 kw system for 3 or 4 years now, and it cost roughly €5,000. It is on the roof and there is nothing to cause any shadows on it.. It faces South East, rather then directly South.. It is very rare for us to have to pay for any electricity at all now, we just pay the standing charges every two months. At the moment these charges are around €33 for two months.

Mike, if you do a search on the forum for net metering, photovoltaic, solar panels and any other key words you can think of, you will find more than one thread. Several of us have net metering systems, if you want to see how mine is after installation several years ago, pm me. Best investment (after house purchase) made by my late husband and I. 🙂

I just realized that it is necessary an update of my post 2 years ago:

Update:
Since March 2019 there are subsidies from the Gov., maximum 1000 Euro per installation (250 Euro per kWp) and also it is possible now to apply for a 10 kWp system.

A subsidy from the government is always welcome.. But I doubt the AVERAGE person would ever need a 10kWp system..

Max said... Quote " and also it is possible now to apply for a 10 kWp system. " unquote....
I just replied that the average person (in my view) would not need a 10 kWp system... I have a 3 kWp system and usually that supplies all we need for a large 4 bed bungalow..
