How big is your PV system

Postby Gordon-Loomberah » Thu Mar 31, 2011 3:09 pm

I thought it might be interesting to see what the nominal output range of solar and wind power systems is like for forum members, and what the average might be, so here it is- the first poll :)

Just add total PV and wind capacity, and hydro if you have a permanent flow (not pumped) system.
Show the total of what you have and what you are about to install, ie - well on the way to having it up and running, not "maybe some time next year".

It's not compulsory, but feel free to add a comment as well.

What about if you're just about to increase your panels to go from a 4.2 to a 5.6kw system ? :)

Then you'd use the 5.01-7kW button, but since that still says 0, I guess no one is about to do it! ;)

This emphasis on bigness is all very good and well but you don't need a big system if you work to minimise your consumption. How about a "How small is your consumption?" poll, or, a "What is the ratio of your generation to your usage?"

Its horses for courses, some have a large system purely to make a profit, others have a large system because they have a business or farm to run, others have a small system to cover their use, or even just part of their use. Off-gridders will need a larger system to cover the inefficiencies of battery chemistry and lightly loaded inverters. It's not a competition, just a comparison to get an idea of what's out there :)

I dont want to fill the forum with a stack of polls at once, there will be more polls coming along soon, including ones along the lines you suggest, and maybe stand alone cf grid-connected numbers.

Everyone should feel free to suggest a poll if it's something that you think others might be interested in.

Gordon

great first poll :)

as with Munter, a poll on the lowest daily grid connected consumption would be great - I want to WIN it :lol:
(ok, my chances are slim, but it would be good to hear innovative ideas across a broad spectrum of measures to reduce greenhouse gas emissions)

Nothing too fancy here. 1100W Sunny Boy and 1.36kW of panels which take up my north-facing roof with a slight overhang on the corners at both ends of the roof.

Other energy things around the house:

Heating: Wood & electric in the main part of the house with a ducting system through to the bedrooms. Wood pellets and an old kero heater in the workshop (ie the whole area under the house).

Hot water: Heat pump (Siddons Solarstream 327 litre) on off-peak tariff.

Cooking: LPG cooktop, electric oven.

Orientation: Windows on all sides of the house. Good for letting the heat in during winter but gets a bit hot in Summer.

Insulation: Ceiling and walls insulated. No insulation under the floor but the area under the house is fully enclosed.

Unusual things: Mouse cage heater uses 65W when it's on. Thermostat controlled however. They're probably the only mice anywhere with their own heater... :D

As the owner of two houses (the one I am living in and the one I am trying to sell), I have one Solar PV system on the house in Alice Springs that is up for sale, this system is nominally 2kW and provided 90% of the household electricty useage. Once this house is sold I hope to install a 3 to 4 kW system on the new house in Perth where usage is expected to be highr due to having three split system airconditioners (one swampy in Alice) and lots more lights especially the 18 downlights (no downlights in the Alice house) and needing to heat the house in winter.
1.5 kW PV and solar hot water installed Nov 2011.

It's important to be trying to minimize consumption as well as increasing the size of your renewable energy system. Remember it takes energy to make these panels too!
