no, I am not looking at getting any sort of revenge on anyone here, but...

Does anyone have any idea of what sort of size of photovoltaic system I should get , what it might cost and what the likely payback period would be on a consumption of about12500 KwH/PA?

[Get Real!]

Just do what I was doing when I was building my house and needed countless products and services...

1. Make a list of the relevant companies (see the list below but do check their location because I’ve no idea where you’re at)

2. Call them all up in turn and ask if they can send somebody to your home for a quote. (in Greek "prosfora" means quote)

I’m sure most can speak English but here it is in Latin-Greek just in case…

“Kalimera, thello prosfora yia fotovoltaiko sistima yia to spiti mou. Mborite na stilete kabion?”

Which means…

“Good morning, I’d like a quote for a photovoltaic system for my home. Can you send someone over?”

3. Arrange it so they all come on separate days.

4. With every rep you meet ask him all the questions you may have and compare his answers to what the other guys have said.

Within a week or two you’ll have their quotes in writing either through the mail or delivered to your door.

From then on it’s a matter of picking the best quote and arranging the installation.

Good luck.

PS: By the time you’ve met 4-5 reps and gone through the process you will have become a bit of an expert on domestic photovoltaic systems, so please do come back here and give us a little write-up so we can learn what you’ve learned and your overall experience. Thanks.

It will be good to know which solar and wind power system can support a single house and which would power a village of about 200 homes.

Isn't google brilliant.

A typical 2 MW wind turbine can provide electricity for about 400 homes.
The costs for a utility scale wind turbine range from about $1.3 million to $2.2 million per MW of nameplate capacity installed. Most of the commercial-scale turbines installed today are 2 MW in size and cost roughly $3-$4 million installed

So here we go, we need to apply of a grant from the EU. Shit maaaaaaaaan this is getting interesting. I wonder if there is any help from GRoC or do we need to convert to Christianly first?

1.5-kilowatt turbine meets the needs of a single home that uses 300KwH per month, in a location with an annual average wind speed of 14mph.

A 1.5 kW turbine would cost approximately £7,000 and deliver around 2,600 kW over a year depending on your location and wind speeds.

This is definitely possible in combination with solar power as one or the other is always going to be available.

2Kw Solar panel costs under £4,000 pounds plus installation. I suspect storage is not included but what the hell. In Cyprus with these two you will have power rill you die and beyond.

[Lordo]

In reality the cheapest option for now is a 500 pound generator which will produce 3Kw power with a few large batteries connected in parallel with an inverter so that they can be charged up and used during the night and the generator can be used less.

Of course sooner or later the other two will be much cheaper and you can have all three then.

It would be useful to know what to expect of average production for each calendar month

Just an idea,

A 1KW solar power system in Cyprus, produces approximately (average) 1650 KWh per year.

This of course varies according to the weather, the direction and the angle your roof faces and if it is shaded in part or not.

According to my estimation, you would need a 7.5 to 9 KW system for your stated consumption. That is if you want to power all of your energy needs from solar, instead of subsidizing your existing energy bill.

Something like this will cost approximately, 1,300 euro per KW, so 9000 to 12000 euro. (this is an extremely rough estimate from someone not in the industry, prices will vary by contractor and the quality of the components)

Then you have to consider how much surface area the solar panels will take and if you have the space for such a system.

Calculating the payback time for such a system is somewhat complicated because the EAC has different fees and fixed service charges but estimate 28 cents per KWh all in. If your yearly energy costs are 3,500 euro, which is just my estimate, you could get a return on your investment in 3 to 4 years. Account for a 5 year payback time to be conservative.

Remember, there are also licensing and application fees, solar cells also lose their efficiency over time and there might be other maintenance costs not taken in to account. Also, you will not be fully independent of the power company unless you choose to store your energy production in batteries. There will be ongoing "administration fees" from them to grid-tie your system for net-metering. So it might take slightly longer for the system to pay itself off. Expect the system's lifetime to be about 20 years.

Also, if I recall correctly, any surplus energy you feed in to the grid gets wiped off from your account once a year. They dont pay you for surplus or let you keep it on your account!

In my opinion, going solar is probably one of the best investments you can make in Cyprus, if you can afford to do so.

I dont work in solar energy but I hope this helps.

That would be the alternative cost, right? Assuming the EAC would pay you way less than 28 cents

Also, you will not be fully independent of the power company unless you choose to store your energy production in batteries.

Given EAC pays close to nothing, you would depend on batteries, right? As the peak production hours presumably would be between 10 to 16, whilst the peak consumption could be in the night for most people (AC in summer)

I dont now the exact monthy costs of energy, because the EAC have different rates for peak and not peak hours, plus fixed additional costs they add to the bill. Peoples consumption between hours will vary.

I did a rough calculation based on my total cost for the last billing period, divided by my energy consumption for that period to get to 28 cents per KWh all in. Thats how much, roughly, we are paying for electricity. At least, thats how much I paid.

You have two options with a solar power systems, you can grid-tie, which means you feed your energy production in to the grid and withdraw energy as you consume it. This is called net-metering, you pay the difference if you are a net consumer of energy or get paid if you are a net producer of energy.

The alternative is to store the energy you produce in batteries. This option has its problems. like running out of power, more expensive, not producing enough power some of the time, or producing more and not having the ability to store it, etc...

The EAC doesnt pay you for any surplus energy you produce and feed to the grid. They just credit your account to offset against any months when your energy production is low or your consumption is higher. At the end of the year, they reset the counter. In effect, keeping any surplus energy you may have produced.

if you dont get a solar power system poweful enough to offset all of your energy consumption needs, you will still have an energy bill. if you get one that is more powerful and produces more than you need, the EAC will keep the surplus, eventually and resell it.

You have to find the right balance according to your needs, estimated production, cost to install the system and the payback time for that.

In my opinion, it would be best to be a net producer than to still have an energy bill after the investment.

[CrookedRiverGuy]

So if you "grid-tie", you have an hourly (or peak/non-peak) tariff? I am asking, because my meter is manually read monthly.

Interesting! I would be fine not receiving money as long as they didn't charge me much in Q4.

If I understand you right; If I have a positive production balance of 1000kWh by the end of Q3 and consumed 1000 kWh more than I produced in Q4, they wouldn't charge me anything for those 1000 kWh used?
And if I only consumed 300 kWh more than I produced in Q4, they would just write those 700 kWh off by January 1st?
