According to reports, balcony solar systems typically save households about 30 per cent on their energy bills and cost and, with no installation fees, can pay for themselves within six years.
The base Ikea model Stream Complete Set S consists of two 450W rigid solar panels and an 800W microinverter. The next level up, the Stream Complete Set M, includes either two 450W or 520W solar panels and includes the Stream Pro Battery, with capacity of 1.92kWh and maximum input power of 1,500W.
For €60 more, you can swap to the Stream Ultra Battery, also with capacity of 1.92kWh, but with maximum PV input power of 2,000W and combining the 800W microinverter.
The range of kits continues to increase, with combinations including up to four modules ranging from 250W to 520W, either the Stream Pro or Stream Ultra batteries, and a variety of mounting brackets. And, of course, each of the components can be bought on their own.
The range of Stream balcony solar kits, which can be bought from the Svea Solar online store, are priced from €449 ($A) for the basic Stream Complete Set S, steps up to €1,229 ($A) for the Stream Complete Set M, and maxes out at €2,379 ($A) for the Stream Complete Set XL with four 520W solar panels, both the Stream Ultra and Stream AC Pro batteries, and basic mounting brackets.
