Mobile PV

Once you get a PV system, the chances are you'll become a PV need. I have become one, even if I don't know or understand the first thing about electricity. 

Today got a mobile PV system. 2 x 400W bifacial ( can generate from both sides) panels, small inverter and a standard household wall plug. German law allows you to have a maximum of 800W flowing into your home circuit. If you can't actually use the electricity, it flows back in to the grid - free electricity for the electricity company.  However if you have a small battery or like us an existing full PV system, then you can either store the energy for the evening & night or you'll get a small credit from the electricity company. They are termed Balcony Power Stations ideal for small rented flats in the city where whole PV issue is complicated.  You don't need permission from landlord, system is plug & play, simple to install and can be taken with you if you move. Cost complete about €300 and that can be saved within 2 years. Warranty on the cells is generally 8 years.

I have bought it to support us in Winter as we can mount it so that snow can be removed easily. So frustrating on crisp, sunny winter days to not get any PV production. 

Naturally it won't cover cooking & ironing all day but should do all the standby equipment & in a single or couple flat, Cover much of the electricity cost, certainly if one had small battery but at the moment the battery costs unlikely to make financially sense. But it makes Nerd-sense!

The panels can be erected anywhere you have a household socket. They won't work if the grid is not working. Some people erect them as fences, but equally at home one car port, she'd, terrace.
