Been gfriends place in Zim past month

Was informed by the biggest diy place in Bulawayo that a 1.5kw total set up ( x fitting would be order of 1.8k usa )

Does that sound reasonable ?? this is with load acid cell batteries not your tesla lithium of course !


the water heater set up is rather cheaper , 150l less 500 usa - like this

Yes just installed 4 kW system 2nd sept 2015 .cost £8500 but wanted better quality panels and enphase individual inverters .panels are on 3 different parts of roof.

I've also got an immersun heater which heats my hot water when excess power is available by powering a 3 kW heater.

12.92 pence is what I get paid for every kWh produced plus 50% of what I generate at 4.85 pence.

In sept I produced 360 kWh
In October it was 180kwh
In November terrible dull weather 60 kWh. I live near Glasgow so further south would get better readings.

I'm are looking to get battery's to power home at night.

I've also got an electric car which was totally free to use in September.

So far I'm happy I went ahead and done it.. The hot water is saving me on gas usage too.

The tariff is supposed to go down to 2 pence / kWh in Jan. So now the time to invest.

Default flat roof 4kw array

Just had a 4kw 16 panel array installed this week on our flat roof. Was quoted £6.7k, normal price is £5.5k for pitched roof but Renusol pods add £1200. Managed to source the pods myself and get the total price down to £5.5k with a bit of negotiating. Seriously considering a Hybrid heating system next with air source heat pump and new combi as our boiler is 20years old now.

They have 75kg of ballast in each pod and Horizon Renewables said this was ample, be a good test if that's enough with 60mph winds forecast here tonight!

Yep, cost £400. Had to have holes cut in the ceiling to check what the joist are. Turns out they are ample (built in 1972), wouldn't advise this on a modern flat roof though, joists would be 2x2s with chip board!

Nothing yet, FITs are paid quarterly and December is my first month, but not expecting much if December is anything to go by, prediction for Dec was 76KWh, ours has produced only 26, about a third as the weather has been so overcast/cloudy. As a whole 2015 has turned out to be a bad year for Solar...

That's the benefit of living further south, stronger rays!

What was your prediction for that period from your quote?

Yes, the south has higher solar irradiance. If you google image search, "Solar Irridiance map UK" you will see what I mean.

Morning Kenny, I can't believe you have 14k+ posts and don't own a Subaru!

We should be meeting up soon for phase II?

Indeed, I've had two in the past and used to be much more active than I am now. I think I joined in about 2001-2 as well.

I was speaking to Richard (tech survey guy) briefly yesterday with a view to getting the heat loss calcs finalised and meeting up again. I'll keep you posted

Question is, do these solar panel work effectively in this freezing weather, or do you have to put your traditional central heating on?

Stored energy must get consumed quite easily in this cold country, for them to keep providing decent heat all year round.

My office building has these solar panels on its roof, and I think they keep the building comparatively a tad warmer than usual. But in all office rooms, we have to put the regular radiators on that run by gas, I think. My radiator doesn't work well, so I also have a portable oil-filled radiator that makes my room hot like Bahamas.

The panels we are discussing here are PV (photovoltaic panels) that convert light into electricity. There is no heat output from them and, in fact, they are more efficient in colder conditions.

The other type of solar panels are thermal panels that have a liquid flowing through them that is heated by the energy of the sun.

My ex -wife's electricity account is in credited to the tune of $A1200 ! Nearly 2 years of A/C -reverse cycle and hot water etc etc from North aspect roof top panels . Australian 44c day temperatures in December house remained ice cold and equally warm in winter . The house was built also with fresh water recovery/storage. Her services outgoings are effectively negligible.
