Using this information, we can work out how large a solar energy system we would like to install. One very important thing to remember is that solar panels DO NOT produce their maximum output all of the time. In winter, we can only expect the best solar panels to produce a maximum of 70% power for 5-hours a day, whereas in summer it is possible to get the maximum for 8-hours. This means that a 200W solar system can be expected to generate 700Wh in winter and 1600Wh in summer.
For solar panels on caravans, motorhomes and narrowboats, we always recommend our DC-Solar monocrystalline panels as they offer maximum power generation and lowest cost. These monocrystalline solar panels are constructed using advanced solar cells which are uniquely connect on the underside, leaving the front free from obstruction as well as being more aesthetically pleasing. Our panels also have a special backing material which reflect light back into the solar cell. The result is a solar panel that is up to 50% more effectient than cheaper panels, meaning a much smaller panel producing the same amount of energy. They also perform far better in low light conditions and are significantly less affected by high temperatures.
The solar panels need to be connected to a charge controller which, in turn, controls the battery charge voltage and prevents any damage to them. To maximise power production, we recommend MPPT solar charge controllers, either the Victron BlueSolar range or the Victron SmartSolar range.
Installation of the solar panels is very straightforward and only a little DIY knowledge is required.
