I've seen lots of solar water heaters on roofs in #Greece, but very few #photovoltaic panels. The country must have many more sunny days than we do. Why is that? Is it because the price of the electricity from the grid is too low or because there is a lack of incentives from the government?

@alatiera @karolherbst I'm not saying solar water heaters aren't good, I think there isn't really a conflict between the two. There is usually enough room for photovoltaic panels even when you have water heaters and I see quite a lot of energy to be covered here during summer: water pumps for pools, air conditioners... But yeah, it's an investment which requires a lot of upfront capital: €5-10k. That's probably the limiting factor.

@psh yes, the production goes down when the temperature goes up, but not dramatically. The annual production of photovoltaic systems on Kos is 50% higher than in Czechia despite higher temperatures according to the EU calculator: re.jrc.ec.europa.eu/pvg_tools/…

@sotiry big solar power plants are definitely more cost efficient, but in Czechia home solar systems have two advantages: the government subsidized them up to 50% of their costs and consumers have to pay a distribution fee for every kWh they consume from the grid and the fee can be as high as 50% of the total price. So home solar systems can still be cheaper for people than consuming power from big solar plants, but using the grid. But if subsidies in Greece aren't big enough and the distribution fees are different, then the calculation can also be dramatically different.
