Solar Panels for Motorhomes - A Novice Guide

Out of the large volume of information I have waded through lately there appear to be a hardly any substantial and valuable guidelines for the non-technical of us. When considering solar panels for motorhomes, there three basic components for implementing solar onto a motorhomes.

1. Solar Panel
2. Solar Controller or charge controller
3. Battery

Solar Panels

Firstly, don't concern yourself about various cell technologies, the 'mono-crystalline' type are the common for motorhomes as they're more efficient and generate a lot more for your money, in nearly most instances and so, benefit almost most people. With greater sales volumes they inclined to be competitively priced. Besides they have long life span. Flat solar panels is the most favorable for install and forget' asunder from an infrequent clean.

Any size you believe you will require it may not seem adequate in reality! This is particularly so more as you adventure more northerly. You will be able to construct all kinds of computations, and nearly all have to presume some kind of counterbalance between good and bad weather. Therefore actually you ought opt for the largest you can sensibly fit and what you can afford. For most trips, the requirement will be between 50-100W solar panels in all probability 80-120W solar panels or greater in the Britain. That stated do bear in mind that their reasonably modest production of solar radiations, can be obtainable most of the time. The numerous hours of moderate solar charging will generally be enough for average electrical consumption.

Solar Controller

Secondly, you will require a regulator or charge controller & cabling and some high-bond Sikaflex sealer and a waterproof cable entry box. Regulators are reasonably simple and inexpensive one-unit affairs or advanced digital units for two solar panels, for wet & gel batteries, and as a secondary 'overspill' connection to the starter battery. There are also a few very pricey controller-regulators that can improve charge rates in low light. With a controller you are able to begin with single panel and add a second if and as you care to.

You are able to acquire four or five times the average solar energy production from a panel by making it perpetually facing the sun. Auto-elevating and tracking panels supply approximately 5x the day by day charge of flat affixed panels. They demonstrate a lot higher gains in wintertime whilst the panel raises to face the low sun. These panels are pricey, frequently close to the equivalent cost as setting up couple of panels, You can not get this much extra from a 'DIY move it now and then', you do need constant tracking to get 5x! Obviously you require a reasonable bit of excess roof space to permit the unit to raise and revolve at will. Although technically very fascinating this isn't actually a favourite alternative.

Apart from total electrical capacity, in that respect there are a few additional advantage in having two solar panels instead of one. In reality only those with greater power requirements will need to spend the more on this.

Battery

Thirdly, battery bank is pretty much necessary because we utilise power in outbursts and broadly speaking to a greater extent of it in bad weather and to a lesser extent in fine weather condition. As a consequence you'll require at the least two leisure batteries to make use of solar energy by storing all that fine weather energy for consumption once the brightness drops.

Do endeavor to counterbalance your solar electrical capacity with appropriate leisure batteries, preferably 2x80/110Ahr leisure batteries with an 80/100W panel e.g. and maybe four batteries with twin 100/120W panels. Check your load though since four x 120Ahr could weigh 150Kgs or more! You are able to of course add solar to a individual 75Ahr battery - you hardly will not realise a great deal do good. 150Ahrs is likely a reasonable lower limit for virtually most people.
