A tenant owner association in Sweden that consists of Building A and Building B will install solar panels.
Building A has excellent roofs for solar panels but lower electricity consumption. If the entire roof is utilized, you get an overproduction of 20,000 kWh/year, which is sold to the grid for an average of SEK 0.6/kWh.
Building B does not have the conditions for solar panels but has a greater electricity demand as there are heat pumps that supply both houses with heat.
In addition to the electricity price, you pay electricity tax (SEK 0.535/kWh) and transmission fee (SEK 0.30/kWh at Ellevio).
With a PowerShare, solar electricity production can be used in both houses, which gives a saving of:
20,000 kWh x (0.535 + 0.30) SEK/kWh = 16,700 SEK/year.
