Forskarstudenten Nelson Sommerfeldt på KTH har utvecklat ett sätt att ta reda på om och när det ekonomiskt försvarbart att investera i solpaneler.

With normal solar cells, you need direct sunlight for them to generate power, and if the panels are at all shaded the efficiency drops significantly. A new type of solar cell, being developed in Jerusalem, is making huge waves because it can generate power

We knew long before we bought our RV that we would want to upgrade the electrical system. Most RVs are designed to be hooked up to shore power (or a generator) whilst being used, and the battery system is usually just to provide a bit of power during travel. As two self-confessed technophiles, living full-time in the RV and harboring aspirations of off-grid living, this wasn't going to work for us.
