This website is interesting and useful.

According to a data, home electricity consumed by generating hot water is more than 50%, so how to save the energy ? Heat pump can help you, which can save you energy up to 50%-75% ! Moreover, ESKOM is provide a rebate R3660.0-R4236.0 ( If a home owner purchases a heat pump and converts their existing 150L or 200L electric hot water tank they get a R 3,660.00 rebate (approx $US 488.00). if the homeowner has an electric tank larger than 200L then he gets R 4,236.00 (approx $US 564.00).

Good news to all of us.

during my experiment i have come to realise a few things which are not quite as i expected...trying to figue out where the 32 000 litres of water i am consuming a months is going.

had words on many occasions with the boss lady in the house about running deep baths to soak in...water and geyser cost etc.

well truth is if your washing machine runs as often as mine does and is a 7 kg plus top loader...best you start by cutting back on this becuase after doing a few runs from the pool to the machine to fill it i realised that the machine consumes between 50 and 70 litres of water per cycle

1 wash = 50 lt
rinse = 50 lt
softner = 50lt

total 150 lt being conservative x that by 4 a day...starts adding up = 600 lt per day x 6 days a week and more sometimes on the weekend...with babies bedding

worrying about what we as a family are consuming is far out weighed by the amount of electricity and water the maid is consuming on a daily basis...eeeish there is no holding back when it comes to

cooking on the stove all day...

washing machine running all day...

iron going 5 days a week..

hot water for washing floors...dishers...anything...it seems the hot water taps runs during the day.

if you have a home phone boy best you be coding it...the last maid we had ran up a R1000 plus bill in the little time she spent here...to cellphones.

so just a tip for those people out there making an effort to conserve energy...

best you take the time to educate the domestic...

Have you considered how much energy is used to manufacture and ship those panels

Tinting the windows on your house or office is an effective means of keeping the building cool, never thought it was true until i actually worked in a building recently, which had the windows tinted while we wer busy working and the A/C units had not been installed yet.

Reversing the direction of an extractor fan is also a means of bringing in hot air from the roof during winter and sucking the hot air out the room in summer.

I have just completed the lighting at Williams Hunt Port Elizabeth and am busy at Chev. 100W LEDs, now light up the place at night. Mercury Vapours have mostly been replaced with 85W CFLs'. Those above the hoists, with 200W. All 8' flourescent fittings have been removed. 5 & 4' Phillips are the replacement. 5 & 4' lamps have also been replaced in existing fittings. This will bring about a huge saving. Problem with the lamps though is the poor quality. I have had to exchange boxes full because they do not work. There have been a lot which did not last 2 weeks before blowing too. The fluorescent tubes are not too bad, about 20 duds out of 600+. The CFLs' however are a pain, about 15% duds. No problems getting them exchanged but a lot of time lost

i took a new 80 watt double fluorescent and hung it at 4 metres off he ground and plugged it in....woooow i got a reading of 700 almost 800 lux and the joke the tubes are tiny thin little ones...i have just found the perfect light solution for future factory lighting projects.

and to replace any 400 highbay fittings where people want to save money.

when i had the fitting on the ground i took it and lit up across the factory and all i can say is wow...one of the contractors who i know have just installed a whole warehouse full of these fittings the problem was the height 13 + metres and i am told they worked out perfectly...i will take a look as soon as i can get a gap.

They are obviously the High Output tubes. You can install them with or without wings(reflector). I put them in the "inspection" area at Chev where they need very good light with the "wings" and at the new fitment centre without the "wings". The reflector makes a huge difference too. They are also available in 54W which is 4' as opposed to the 5' 80W.

Reduce your electricity account by skipping the washing machine's pre-wash cycle if your clothes are not particularly dirty. This will use up to 20% less electricity. You can also use one large light bulb instead of a few small ones. One 100-watt light bulb uses less energy and gives off more light than two 60-watt bulb light.

One 100-watt light bulb uses less energy and gives off more light than two 60-watt bulb light.

Rather use an LED lamp, the savings can be as high as 90%, depending on the application.

[Sparks]

We've had a few clients asking for a quote to retrofit with LED light fittings - certainly seems to be gaining momentum, although at this point budget constraints are an issue.

Taking the Eskom rebate into consideration when getting rid of 50W downlighters, high wattage fluorescent, Mercury Vapour, and Metal Halide lamps does help to bring the cost down.

The Eskom rebate on Heat-pumps and Solar geysers will apparently cease at the end of March 2013, I am not sure about the rebate on lighting yet.

Cant wait for the rebates to end, maybe then the prices will become more realistic for the general public.

Refrigerator and freezer doors should seal tightly. Loose seals cause your unit to work harder and use more energy.

In my private apartment I changed following things:

I now use energy-saving lamps
I now have a laptop instead of a PC
All my electrical appliances are in remote controlled electrical sockets, so I can switch them off togehter, when I go sleeping
The radiators are not covered
I shower more than that I bathe
All my water connections have a limit on water flow
I use the microwave when it is useful and I use the stove when it is useful.
You also save more energy using a dishwasher, instead of doing it by hands.

and so on..

Guten Abend

I hope all is well in Germania

I have a question for you..
What is your best “declassified” output spec for small solar panels?

Auf Wiedersehen

[Solar Ingenieur]

Hello,

all is well. I hope the things are going well here too.
I've no quick answer for that. Are you an installer of solar panels?

Bye
