Conclusion

When going for a solar setup in an off-grid system, it is vital that you get what you want. Estimate your power usage, its frequency, and volume. You don't want to be running low on power with high usage, so going for a higher capacity would be the right thing. Also, neither do you want to be short on options for powering your devices. It is a balancing act. The monetary value should be your last concern. Getting stuck at the campsite with an inadequate power system is not something you want to happen. For only lighting purposes, go with the Photonic Universe Solar Lighting System. But if you want the whole package, go for the Renogy Solar Kit.

The Crux of Solar Panels

Solar panels were invented with the idea that the energy existent in various forms can be translated from one form to another, and specifically harnessed for a particular need. Through a process regarded as the Photovolaic effect, solar panels can be made to trap sunlight and convert it from sunlight to direct current (DC), which is subsequently changed into alternating current for the electrical circuits in a building and/or vehicle.

The excess energy may then be fed-back into a battery storage system for subsequent use or into the electricity grid for which you could be paid an initially agreed feed-in tariff.


​What Kinds of Solar Panels Are There?

Most solar panel cells are made from silicon – the panels, are each made from several solar cells which are connected together and sandwiched between protective glass and a backing plate, which is all embedded in an aluminum frame; depending on the manufacturing processes of the silicon cells and their assembly however, the panels come in two main types;

Crystalline Panels:

Crystalline panels are manufactured in two kinds – mono-crystalline panels and polycrystalline (multi-crystalline) panels. Mono-crystalline panels have a reputation for higher efficiency than the latter. This difference in efficiency usually translates to the fact that you’ll likely need a larger poly-crystalline panel to generate the desired amount of energy you need; the difference however, is quite negligible since, in practice, there’s no clear advantage either way; and as with most high-tech products, solar panels are only a complex assembly of many components and their overall performance depends on more than merely the type of cell.

Thin Film panels:

Thin film panels are generally considered the cheaper alternative to crystalline panels and are made by spraying a thin layer of photovoltaic material (such as amorphous silicon, casmuimterlluride or copper-induim-galluim-selenide) on to another base surface, usually of glass or metal material.Solar panels also come in free-standing and roof-mounted types, each of which are specifically adapted to suit various specifications.While free-standing panels can be positioned upright or otherwise to catch as much sun, in whatever direction is necessary, rooftop panels are permanently fixed to the ‘roof’ or top of the caravan or motor home.

Both designs have both advantages and drawbacks in that, while free standing solar panels can be utilized to an utmost, being capable of being positioned and re-positioned to catch as much sun as possible, the rooftop designs are permanently fixed and as such cannot be easily angled to catch the sun. However, while the former might be cumbersome and difficult to store while in use, the latter neither takes up any storage space nor require any separate means of transportation. Not to mention the free-standing designs have been complained to attract flies and insects, obscuring the sun and rendering its flexibility somewhat counterproductive.
