A local firm(Northern Ireland) with a good reputation currently sells a 2 panel solar thermal system suitable for 4-5 person household for £3000 and a 3.5kW PV system for £6200. They claim payback periods of around 6 years for both. From what I have read, the immersion controllers for PV systems are usually in the region of £500.

The cost of heat pumps, air or ground source can vary greatly and will depend on your home's requirements so I'm not sure what cost is fair to assume for comparison.

A basic observation to get things started would be that the solar thermal only contributes to DHW whereas PV can also offset your general electric consumption and the heat pump should take care of your space heating requirements.

In our climate do you perceive any of these options to be more reliable or with the potential grants and payments could you be swayed on a financial basis?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11250 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11250 Fri, 11 Oct 2013 09:30:26 +0100 SteamyTea To stop the ruck getting out of hand let's avoid planning law and subsidies/incentives legislation.

I was musing from a different perspective.

We are on grid.
Even during overcast winter days we are still exporting >100W through most of the day.
During this time it is the short bursts of power hungry appliances that result in us buying in electricity.

This makes me think that a relatively small capacity battery system could dramatically improve our self usage.

So does a long cycle life battery system with ~1kwH capacity and max output of ~3kW exist (if not which part of this requirement is the limiting bit).

If it exists how much would it cost and many cycles would the batteries be expected to last?

I'm looking at fitting solar thermal panels onto a detached garage roof. The cylinder (heat bank) is on the ground floor of the house. The pipework will run from the solar panels, down the garage wall, under the ground between the garage, into the house and up to 350L thermal store. The thermal store is already in existence as is attached to a gas boiler and wood stove, it has an unused solar coil fitted. The distance from end to end will be about 30m, which means a 60m feed and return circuit.

The questions I'm hoping someone can help answer are:

1. Is the circuit too long to be practical?
2. Will a standard pump would be able to work over that distance?
3. At night, in winter or on really cloudy days, a lot of water will be sat in the circuit at low temperature, will this act as a heatsink and cool down the water in the thermal store.
4. Following on from Q3, on cloudy days will intermittent operation of the pump cause the colder water in the circuit to also cool down the thermal store?

I guess what I'm really trying to find out is whether I should fit solar thermal (as I already have a solar coil in the Thermal Store) or just fit PV panels and use spare generation to power an immersion heater?

I am looking at fitting panels that are 3m long and 1100 wide (both PV and thermal are this size) and can fit 4 across the width of the roof. The PV panels each generate 500w. I could therefore either fit 4x pv to provide a max of 2KW or 2xPV and 2xsolar thermal to give 1kw electricity and hot water.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11145 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11145 Mon, 16 Sep 2013 06:57:49 +0100 SteamyTea Not sure if all the units used in the report are correct, but no matter.

The boiler itself would have to be sited 50-75m away in an outhouse (noise/mess/no room inside etc.) ... but would it be ok (or even preferable) to keep the actual thermal store inside the main house? I gather that solar thermal is quite a good companion to a wood boiler as it cuts down on the more sporadic summer use, and we have a nice big flat roof on the main house where we can site this. Basically want to keep all the pipework to a minimum ...

some of the script
"Our civilization runs on oil.
It’s the cheapest, most energy-dense and portable fuel we've ever found. Nature required tens of millions of years to make petroleum, and we've used up the best of it in less than two hundred.......
The oil industry is now staging another PR counter-offensive. They're telling us that applying "new" technologies like hydrofracking to low-porosity rocks makes lots of lower quality, unconventional oil available. They argue we just need to drill more to produce more. Problem solved!

But wait. What's actually new here? Most of this technology has been around since the 1980s. The unconventional resources have been known to geologists for decades. What's new is high oil prices.
It’s high oil prices that make unconventional oil worth producing in the first place. It takes lots of money and energy, not to mention water, to frack low-porosity rocks. And the environmental risks are staggering.
How does the economy handle high oil prices? Well, it turns out the economy hates high oil prices and responds by going into recession. Which makes energy prices volatile, rendering the industry subject to booms and busts

So, what’s the bottom line here?
Yes, there's still oil in the ground. We just can't afford it. In broad terms, the peak oil analysts were right. But the fossil fuel industry is winning the PR battle.
What really matters, though, is not who wins the debate, but how we prepare for the inevitable. We’ve got to wean ourselves off our high-energy lifestyle.
We'd be foolish to wait for events to settle the debate once and for all. Let's say goodbye to oil. It's saying goodbye to us."

Last year was a disaster year with flooding poor weather and the finishing of the complete refit on the house. The solar thermal was found to be without pressure and so while moving the heatpump the system was drained down and reinitialised with new Glycol. Everything seemed to be working fine, but the temperature it produces is way below my expectations.

On a good day it makes a maximum of 50 degrees C and mostly makes around 45 degrees. The heat pump has to top up the water pretty much everyday. I had a guy around to look at it and he said it was working fine, but it was an overcast day.

I think I could leave a tank of water in the loft and it would heat up quicker and higher than the tubes are producing. The guy also said washing the tubes might do the trick. They have never been cleaned, but could some dust really effect the temperature that much?

What sort of readings should I be seeing from a panel of 16 tubes?

"The National Grid operates back-up generators to cover the sudden and unexpected loss of wind power to avoid power cuts. Last year one electricity generator admitted that for every 1MW of wind electricity penetrating the grid, there was at least 0.9MW of back-up operating. These back-up generators are gas-fuelled, producing carbon dioxide."

The wording of this seems to me to be a bit disingenuous as surely the back-up needs to be available not operating?
He actually makes a strong case against W.T's but some of the figures seem high eg:

"Costs of back-up generation are estimated to rise from £18m currently to £400m in 2020"

Really? if all this is true then the more I read about W.T's the more uneasy I become about the:

So using pvgis (thanks Damon) I calculated the clear sky irradiance of the two 45 degree inclination arrays 1.75kW SSE(-11) and 2.25kW WSW (-79) for May.

The pvgis fixed plane clear sky irradiance is multiplied by panel efficiency (15.4%) x panel area (1.6m2) x no of panels (16) x non-panel system efficiency (90%). The the two aspects summed for each time interval.

This only holds for a perfect cloud free days so I was rather chuffed when day 1 was the start of our mini heat wave!

The only fudge factor is the non-panel system efficiency (inverter + wires + panels getting hot + etc) which pvgis suggests as 86% but I got a better fit at 90%.

So it seems at a first (and arguably second) order pvgis is a very good predictor of clear sky irradiance and that my array(s) 'does what it said on the tin'.

Now it just 'weather' to investigate - I think I should hold off for a bit before making any impressive claims for annual yield based on the 5 days since install..]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10806 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10806 Wed, 19 Jun 2013 17:52:45 +0100 Noodle

As I am little more energy concious I told him to look at PV to help with electricity production and it would help his carbon footprint. Although he does rear his own animals for meat, he has chickens etc so he is not all bad. Anyway, his roof orientation looks pretty good but how much of an area does a 4kW system take up?

Skreiberg is leading a team at Norway’s SINTEF Energy Research where samples of the logging waste regularly arrive to be transformed into fuel.

In the raw form in which the biomass arrives at the laboratory, it is regarded as a problematic and therefore low-value fuel.

But when the scientists and technicians have finished processing it, they are left with a valuable source of heat – ready for use in industrial heating furnaces that are currently fuelled with wood pellets or chips, and for Norway’s domestic pellet stoves.

They would be able to provide energy at constant rates in linked in pairs (high and low) would be in the sea do not look ugly like wind, have a lot going for them.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10409 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10409 Fri, 29 Mar 2013 10:14:52 +0000 CWatters
It seems that something is changing the mercury in the bulbs and it might be an unexpected nuclear reaction...

"Harmless low-energy nuclear reactions may be taking place routinely inside of compact fluorescent lightbulbs, according to a physicist whose theories have NASA researchers abuzz with the prospect of cheap, non-polluting energy."]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10368 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10368 Fri, 22 Mar 2013 21:57:42 +0000 Billy-J
I was wondering if anyone on here has a small/micro wind turbine?
When I say small I mean something that could power your average house and be grid connected directly not via batteries.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10402 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10402 Wed, 27 Mar 2013 12:21:07 +0000 pbib I am researching public perceptions of smaller wind turbines and I would be grateful for your views on this subject.
There are only ten questions, but they are open so please feel free to voice your opinions. You don`t have to have had any experience with wind turbines to complete the survey it is just about perceptions. It is totally anonymous and there are no personal questions.
I hope you find the questions stimulating and I will of course post the findings of my dissertation which members may find useful, (or at least start a lively debate !)
Again many thanks for your participation.

4 February 2013

A record amount of electricity has been generated by wind energy in Great Britain, according to National Grid.

The new high was reached on Sunday morning, when wind generated more than 5 gigawatts for the first time – more than 12% of the nation’s electricity needs for industry, businesses and households – enough to power more than ten million British homes.

It’s the first time that wind energy has exceeded the 5 gigawatt threshold in Britain.

RenewableUK’s Deputy Chief Executive Maf Smith said:

“This new record proves that Britain is generating an increasingly significant amount of clean electricity from wind. The quantity of low-carbon energy that wind is feeding into the grid is continuing to surge upwards. We’re set to generate at least 15% of the UK’s electricity from wind by 2020.

I remember Viking House mentioning this as something he does, but can't find the thread now. Can anyone point me in the right direction, or help with other sources of information on this, please?

Ta,
