About Solar Panels

about solar panels

Solar Panels are available in 3 main types :

Amorphous
Monocrystalline
Polycrystalline

The Amorphous panels have a better average output in cloudier conditions. They are also about double the size of the Mono/Polycrystalline panels of the same wattage.

They are usually brown in colour. However, can be very brittle.

Polycrystalline are made from molten silicon that is poured into a mould and then sliced into cells or monocrystalline, (our panels) these cells are slices of pure crystalline silicon which makes them very efficient.

There is slightly better output on the Mono's than the Poly's.

You can connect a Solar Panel directly to a battery, but we recommend a regulator box is fitted on any Solar Panel of 15 Watts and above, this then protects the battery from being overcharged if left connected to the battery for any length of time.

Choosing the right Solar Panel for you:

Generally the more Solar Panels you have the more power you will produce.

This is mind doesn't mean you need loads of power just to keep a battery topped up through winter months.

Many campervans/motorhomes will likely have two 110amp leisure batteries.

If your looking for a Solar Panel just to keep your battery/s topped up through winter months in most cases just a 20-Watt Mono panel will work fine but make sure the panel will get as much sun light as possible. Don't forget you'll need a standard 10-amp charge controller box to protect your battery/s. A 20-Watt Solar Panel will work as long as all appliances are disconnected.

If you keep lets say an alarm system on a motorhome/campervan/caravan then we would recommend a slightly more powerful panel such as a 40-Watt and of course a charge controller box.

The larger more powerful Solar Panels we sell like 60+ Watts are aimed for re-charging your batteries when out and about.

Fridges can draw on average 1amp per hour when turned on. This doesn't sound a lot but of course thats 24amps per 24 hours. If its a fridge you will be using among other items we strongly suggest opting for a 100-Watt + Panel.

Most people will have a shower, lights and maybe a 12volt TV so even then this is where the 100+Watt Solar Panels come in to use.

We hope this information helps you out.
