Solar Panel Subsidy

Anyone thinking of installing solar panels may be in for some bad news.  A leaked report states that the subsidy is being reduced and an announcement is expected next week.

Re: Solar Panel Subsidy

The trouble I have with these reports if they get one key fact wrong do I trust the rest of the report?

Over 25 years this can mean a tidy profit as long as they stay in their homes over the break-even point.

You will still benefit from the feed in tariffs even if you sell the house.

Re: Solar Panel Subsidy

People around me with electric solar panels feel conned, as the cost of the electricity they save as a result of their panels will only just about cover the installation costs - assuming the panels last the full quoted lifetime and nothing goes wrong.  In addition the profit they were hoping to make from the feed in tariff varies between nothing and a maximum of about a third of the KWh that was quoted as 'typical' by the salesman and site survey people.
I understand that hot water solar panels (for hot water and heating) are much more successful, but obviously don't give the opportunity to sell on any excess energy generated.   Roll eyes

Re: Solar Panel Subsidy

Frankly I've always felt it a bit unfair anyway. Those who can afford their own homes get subsidised solar panels by those of us who can't - who are paying for the panels through our energy bills.
Hardly seems fair from my POV. IF you can afford your own home these days (and those numbers are dwindling) it seems a bit unfair to expect those of us struggling to pay rent to subsidise you - we're getting nothing for it and those who can afford get it a house with subsidised additions to push the value up even more.
In some places and times that would almost be classed as slavery.
I need a new signature... i'm bored of the old one!

Re: Solar Panel Subsidy

Solar water heating can be an even bigger con.  I was certainly conned by a firm that has twice been done by trading standards and is still operating, they have been fined over £20 000

Re: Solar Panel Subsidy

two cuts from the above reports PDF
my roof ridge is north/south so from the first I can only expect about 40%
since instalation I hve done away with my bath and only have a shower,
got a new washing machine, you cant get hot fill now
got a dish washer, again you cant get hot fill
So in the hot summer Crazy  get loads of hot water and no where to use it, in the winter nothing
Electric PVA panels work all year, but some firms will not fit them on North/south ridge

Re: Solar Panel Subsidy

Now that a lot of homes have double glazing, the sales men have found another source of sales namely solar panels and solar heating. There's no doubt the technology works, but the sales guys and their managers will habitually manipulate the performance figures to increase their commission.
Do not believe a word they say unless you can verify it elsewhere and it is written clearly in the contract.
Now Zen, but a +Net residue.

Re: Solar Panel Subsidy

It will be interesting to see how the companies selling panels react to this if the reduction is announced.  it will have a dramatic effect on their business.

Re: Solar Panel Subsidy

Why in these DIY solar panel projects do they always use loads of very expensive copper pipe to build a heat collector ?
Would it not be more efficient and cheaper to buy a decent sized second hand (eBay < £5) single panel radiator and paint it black ?
To aid convection, the radiator will need to be mounted upside down so the heated water rises to the exit pipe, and the cooler incoming water will fall to the bottom of the panel.
Then you have the whole panel area collecting heat - so should be more efficient.
A radiator will be much less prone to air locks than loops of pipe, and venting only needs to be provided in one place in the design.

Re: Solar Panel Subsidy

Instead of using copper piping, you could use ordinary plastic garden hose, and paint it black.. after you have fitted it into the box,....
..   no joins, no leaks... and you lay it out just the same way... Smiley

Re: Solar Panel Subsidy

I have used a tightly packed spiral of 120ft black and dark green garden hose on the garden patio, as a heater for the kids pop-up swimming pool (8ft diameter by 30" deep) simply by connecting it in series with the pumped pool filter.
It was much cheaper than using the proper 3kW pool heater, but did have the disadvantage of at night of either disconnecting the hose, or switching off the filter pump, so as not to cool the pool when the sun wasn't shining.  Unfortunately the pool is only fitted with one pair of external hose connectors (for external filtering and heating) , otherwise it would have been easier if there was the possibility for a second external loop that could be dedicated to heating, and leave the first loop for filtering.
