Capacity factor?

Photovoltaic capacity factors cannot even theoretically exceed 50% even at the equator because out of every 24 hours, 12 hours is night, so you always need to at least double the figure for PV to get the real cost per average watt.

If you make power with solar for most of the day every day, you are decreasing pollution and increasing long term sustainability. This is worth it.

It's a bad idea to be overly idealistic about anything.

This is worth it.


The point is, that if you're making a comparison between two sources of power, one that cost $2.50/Watt and is available 20% of the time, and another that costs $9/Watt and is available 80% of the time, which one produces electricity cheaper?

Of course the market size in Ghana isn't big enough for a nuclear reactor to make economic sense, but this is about the principle.

So many people simply lie about the potential of photovoltaics by these simple omissions.

The comparison isn't apt. Ghana can't compete with other countries when it comes to buying energy sources on the world market (especially when the prices will inveitably rise due to declining sources and/or increased demand). It also has no economic/military strong-arming potential to force access to energy sources.

Transforming to a source of energy that they have themselves is only prudent.

Usage of eneryg isn't the same 24 hours a day. The overwhelming part is used during the day.
The advantage of nuclear to produce power at night isn't as great as it's made out to be (actually it's much less so since nuclear power can't be regulated that well - which means if you go all nuclear you'r dumping a lot of power unused at night)
