Today, the last solar modules were mounted, and we started with the wiring. There’s a total of 20 solar modules, divided up into 5 groups – i.e. four modules are connected in a row, and form a ‘string’, which are two cables individually connected to the DC/AC step-up converter. That’s a lot of wires, which had to be squeezed beneath roofing tiles, glass wool, and other obstacles.
Anybody knew that electricity generated by photovoltaic cells (aka “solar cells”) can be passed into the power grid in Germany? In fact, the local grid company must accept it (and yes, even pay you for it, just the same as it pays the nuclear power plant next door).
Which is a nice thing indeed, as I’ve some square meters of my southwards roof to spend, plus some boxes sucking electricity 24/7 and gnawing at my conscience.
So I went for it, and construction started just yesterday – laying the grounds for a total of 3.1 kilowatts peak solar power.
