Is that 54p per kwh. If it is that aint half bad. Imagine if you lived on a farm & had wind gen as well as solar. You could actually make some good money. I once looked at a property at the side of a pretty fast flowing river. I bet it could have sustained at least a 5kva or more water turbine. Just had a huge thunder & lightning strike here in Leeds. Weird weather we are having.

I had panels installed just before the payment was reduced and have kept a monthly record of the output. This allows me to check if there is any fall off in generation from one year to the next and so far the readings are about the same. I never clean the panels as we live in West Wales where the Atlantic weather ensures that the rain comes down with force. This morning the short, sharp showers of hail virtually blasted anything outside the shelter of the four walls. During the last 12 months I have had several offers from "cowboys" to reconfigure the panel wiring and fit a new converter as a way of guarding against failure. All those offers go straight into the bin.

Bill, I would like to know more about this solar boost box for hot water. I have not heard of that before and it would help a lot if it can be fitted to my system now. There may be a problem since every year I get a form from the electricity supplier to declare and alterations.

I bought a pre owned Solar Boost controller via ebay for £90 when it arrived the the clamp on current transformer. and sender wasn't present. That was no problem as I looked on the net and phoned up Solar Boost and they supplied one for I think around £10 it was several years ago. As I intended to use the immersion heater, I disconnected it, and use the wiring circuit for Solar Boost. Our immersion heater has TWO thermostats, as all modern ones should have (well one and a over temp resettable trip) The clamp type current transformer is fitted around one of the meter tails, it must be clamped in the right or correct direction. Most of the time we have enough hot water for showers and domestic duties, and plenty in the summer months.

Similar to Ray above, we have had during the last 12 months, several offers from "cowboys" suggesting how they can reconfigure the panel wiring and fit a new inverter as a way of guarding against future failures. We keep a check ourselves and will know if things are OK or otherwise. We was an early bird on Solar PV and the income has more than paid for the installation,long may it last. John

The chart above shows the output from my 3kW system located in North Derbyshire. The interesting thing is how consistent the output is over the years. The supplier said it would take about eight and a half years to recover the costs and I've done it in eight. I've got a solar boost unit on my wish list, interesting to read comments about it. Not so sure about needing to clean the panels, unless you can do it for nothing. I doubt you would recover the costs if you had to pay someone to do it.

Hi All,

Yes we get 54p per kWh. Plus 3p per unit based on 50% of each quarters reading for energy sent to the grid.

We are lucky to be in South Dorset and have an optimum incident angle and roof alignment for best "reception" of the incoming rays!

Our Fronius inverter works really well and has a removeable drive to allow monitoring of the statistics.

Cleaning never seems to be a problem.

The installation has a 10 year warranty for the panels, contract is 25years.

Now looking at a Tesla PowerWall now that the prices are coming down.

Cheers, Martin

I use an "Immersun", think thats how its spelt, to divert power to the immersion heater. Two attempts to get one that worked properly, couldn't set the time on the first one, otherwise its been good.

Tesla's Powerwall, is it worth it?

Re. comments after my earlier posting about solar panels maybe needing an annual clean.
As before, " Depending on your location and therefore amoount of "dust" in the atmosphere".
We live in a rural area and soil erosion in high winds & rain means there is a lot of deposition.

I suppose If your house windows remain clear after 12 months without any cleaning, then don't bother about the panels.

Around here. our (vertical) window glass becomes quite coated in dust, bird cr*p & muck in 6 weeks so an annual clean of the panels seems worthwhile.
