The average turnkey price of a typical 7 kWp household #rooftop#solar system in #Finland has dropped to 7.700 €, as demand slowed down and there are no more shortages in component supply or skilled installation personnel.
Households can also apply for a 40% tax rebate on the installation work, which probably brings the total cost to below 1 €/Wp.
Demand for batteries and DSM automation exceeds expectations. There is no feed-in tariff so consumers try to avoid feed-in. https://yle.fi/a/74-20079845
@henrihorn so what’s the renumeration for feed-in? Wholesale energy price? The (translated)article says: “because the electricity sold to the electricity grid is comparatively poorly compensated”.
@burger_jaap
Most commonly the hourly (soon 15 minute) spot market price without transfer fees. As the most likely times of excess energy are those with lowest spot prices, the average sell price will be far lower than the average net buy price. @henrihorn
@osma@burger_jaap The compensation for micro feed-in electricity is specified by the seller, and companies can compete on this. Spot price minus 0,2 or 0,3 cent/kWh seems typical. In addition, the local distribution company is allowed to charge 0,07 cent/kWh.
Are there studies showing that solar feed in prices are lower than average spot? Daytime prices are higher than night, which benefits solar power. But winter is also costlier than summer...
Solar share is still too low to affect market
@henrihorn
Average spot is not not the same as average household buy price. Most expensive hours (morning, early evening) are often when households most need energy and also not the best solar production hours (mid day), while most expensive months (winter) have near zero solar production.. @burger_jaap
@osma@burger_jaap Your claim was that the most likely times of excess solar energy are those with lowest spot prices. I was expecting more empirical data to support that claim.
