Storage of solar energy at home

In a test building, they were able to increase “own consumption” – solar power used directly within the household without being exported to the grid

Home Solar Power Storage — Another Option Clean Technica, JUNE 15, 2012 BY ZACHARY SHAHAN  In addition to the home storage option recently announced by Panasonic, below is another story about a some storage option that could greatly benefit those with cheap solar power on their rooftops in Germany (and some other locations). This is a full repost from the awesome site Renewables International : Researchers in a Franco-German project have come up
with a power storage system that considerably increases direct
consumption from roof arrays. Such applications are becoming
increasingly important in countries like Germany, which has
implemented a kind of real-time net-metering called “own consumption.”
As a part of the Franco-German Sol-Ion research project, scientists at
Baden-Württemberg’s Center for Solar Energy and Hydrogen Research
(ZSW) in Stuttgart have come up with a new storage system for solar
power. In a test building, they were able to increase “own consumption” – solar power used directly within the household without being exported to the grid – by 26%. The ZSW says the amount of energy
stored in the new system covers the average power demand in a
single-family home of four people in the evening. In other words, the
system turns fluctuating, intermittent solar power into a source of
energy that can be consumed as need be.
The Sol-Ion storage system is about the size of a normal household
freezer. It contains the power inverters needed for the solar array as
well as a battery charge rectifier, both of which have a nominal
output of five kilowatts. The system also contains electronics for
device controls, which the researchers optimized. They then collected
data during various long-term tests over six months. Lithium-ion
batteries with a useful storage capacity of 6 kilowatt-hours are the
centerpiece of the system…..
