Peterborough Motorhomes supply a range of solar panel systems and solar power modules and can fit them too if required. From handheld battery chargers to integrated roof mounted solar panel systems, we can advise of the most appropriate system for your needs. The cells are laminated between a sheet of high transmissivity, low-iron 3mm thick tempered glass, a sheet of TPT material and by two sheets of EVA to prevent moisture penetration into the module.
Choose from a range of premium solar panel kits and either fit it yourself or have the competent technicians at Peterborough Motorhomes install it for you. All premium solar panel kits come with a 2 -10 year module warranty and are supplied with cable, connections and detailed user instructions.
Once charged, their internal batteries can either power an iPod for 18hours, a mobile phone for 44 hours, PSP for 2.5 hours a PDA for 22 hours and much much more. Peterborough Motorhomes can supply the FREEloader range of portable solar power devices and systems for use in and around motorhomes. Freeloader Classic: An advanced portable charging system that can power any handheld device anywhere, anytime.
Supercharger: A weather resistant unit that will charge the Freeloader Classic in as little as 4 hours in sunshine. Freeloader Pro uses its high power solar panels or USB (cable supplied) to quickly charge its internal battery (7 – 9 hours in sunny conditions). Also by switching its Multi voltage switch to “9.5v” Freeloader Pro is capable of charging power hungry, high voltage devices such as MP4 players, portable DVD players and SLR camera batteries. Supercharger is a fully weather resistant unit supplied in a tough case with two innovative buckles and a Velcro attachment strap for secure fixing to a rucksack, travel bag, bike panniers etc. You also need a solar charge controller (sometimes called a charge regulator) to keep the panels from overcharging your battery. All of these ancillary bits I ordered from RV Solar Electric, one of the standard sources you always hear mentioned when this subject comes up.
Our roof space is severely limited, and we had specifically picked out these panels to fit on the front corners of the roof. They neglected to install any fuses anywhere in the system, contrary to every accepted electrical practice. They wired the charge controller output straight to the battery, bypassing both the battery disconnect switch and my ammeter, thus preventing me from being able to monitor the rate of charge from the solar array.
In the process of going to the battery, they peeled back the sealant between the battery box and the inside of the camper and left it open, potentially allowing explosive hydrogen into our living space should the battery offgas. RV Solar Electric hadn't sent us enough panel mounts, so this shop offered to make us the ones we needed.
Generally, the quality of the work was sloppy and shoddy, with incorrect connectors forced to fit on the charge controller and lots of insulation & wire bits left strewn about the interior of the camper.
Which brings me to a separate point – what's an RV owner to do when they need work done? I believe this is mostly because they were installed in October, I'm writing this in March, and we're in the northern hemisphere – meaning the winter sun is far from being directly overhead. Which brings us to one last, big question: how much electricity can we realistically expect our panels to produce?
Our design rule is that a solar panel will contribute as much as half of its wattage, in amp-hours, each day if aimed at the sun and perhaps 25% if randomly oriented. The Design Tools from Sustainable Design Studios, for acquainting me with the basic terminology and equations of solar position calculations. Visual Calculus from the University of Tennessee – Knoxville, for refreshing my embarrassingly rusty memory of integration.
The Photovoltaic Program Publications from Sandia National Laboratories, and the Solar Radiation Resource Information at the National Center for Photovoltaics (National Renewable Energy Lab), two outstanding sources of general information on PV performance parameters. We've now had our solar array through a summer, and it's been suggested that I add a few words here about this experience.
First, shortly after I wrote the above article, the panels got to a point of producing enough for all our electrical needs, under good conditions (sunny days, no trees, etc.). Second, as the summer really got going, I started to notice serious degredation of the panel output due to heating. But that was high summer, and we're back into autumn now, meaning that we're again starting to look for electrical hookups when I have work to do. Just a quick addendum: in early 2004 we filled most of our remaining roof space with two small panels, a 50W and an 80W.
The heavy duty anodised aluminium frame provides high wind resistance and convenient mounting access.

From 5Wp to 150Wp, these solar panels are ideal for a range of uses, whether you just want to prevent battery drain in your motorhome or create energy self-sufficiency in your vehicle. For a simple explanation of how they work, the solar panel charges the battery of your caravan, motorhome or boat during daylight hours.
It takes power from its solar panels (charge takes 8 hours) or via a supplied charge cable that plugs into a computers’ USB (3 hours). Secure the featherweight Supercharger to your rucksack, travel bag or bike panniers to charge your Freeloade Classic whilst on the go. Once fully charged Freeloader Pro is capable of delivering enough power to give a mobile phone 70 hours of standby time, 5000 page turns on an eBook or a 100% full charge for a digital camera battery. The metallic push button “Power Halo” indicates how much power is in Freeloader Pro’s battery. CamCaddy accepts virtually every type of camera battery whether a simple compact digital camera, professional SLR or a video camera battery.
Supercharger will fully power up a Freeloader in as little as 4 hours in sunshine, which means it is possible to charge Freeloader twice in one day!
The lure of clean, silent electricity from the sun, including the implication of freedom from electric hookups, was undeniable.
Our Lance had been available with an option for a 50-watt panel, but we hadn't ordered it – not because we didn't think we wanted solar, but because we knew we could fit way more than 50W worth up there. Big solar panels (officially called photovoltaic (PV) modules) are one of these things that are only made by a few manufacturers, but are sold by many dozens of retailers for vastly different prices.
And I selected ETA Engineering as the place to buy them from; they had a good, usable website and their prices were about as good as anyone's.
You also need mounts to attach them to the roof: For RVs, these come in 2 basic varieties, fixed and tilting. If you have a small enough panel, it puts out little enough current that you can get away without one, but with 240W up there our charge would definitely need regulation.
Although their panel prices weren't competitive, the other prices were, and they know their stuff.
This RV shop, which had been recommended as a good place to get electrical work done, screwed up the job in almost every way imaginable. Horror stories much worse than these are rampant in the online RV communities, and even in our own (very limited) experience, 4 out of 5 RV shops can't be trusted to do quality work.
After redoing most of their work, we now have a functioning solar system, the heart of which is those two big 120-watt modules. It seems that individual modules are typically meant for a 12-volt system like ours, and are rated with a wattage number (like 120).
How well do our solar panels do the job they were purchased for – supplying me with enough electrons to earn our living? But you can see that half our load is my work, meaning that on days when I'm not working, our panels can generally keep up. You might wonder why I'm talking about the camper battery so much in a Solar Power article. Well, fair enough as far as it goes – that is actually about what we're seeing these days.
The NREL site also has a nice interactive US map that will give you numbers similar to this calculator, but the catch is that if you're not a solar enthusiast, its results are a bit hard to interpret. Every module has been designed in accordance with IEC 1215:1993 standards, manufactured with proven materials and tested to ensure electrical performance and service life. As a result of the exceptionally high standards of construction all our solar modules are covered by a 25 Year Output warranty. The power in the battery is available for use at any time to power appliances – directly if powering 12V appliances, or through an inverter if powering 240V appliances. Made in tough aluminum and finished in a stylish “piano” black, Freeloader Pro is the perfect companion for adventure travelers, explorers and anyone who demands the best!
By using an ultra efficient, compact, 1.5watt crystalline solar cell, Freeloader can be rapidly charged in all weather conditions. And a lot of people don't realize this, so the big-name retailers like Camping World charge premium prices. The tilting sort allow you to prop your panels up so that they're facing the sun more directly, and thus catching more rays. We bought a fairly basic controller, a SunAmp 22A, not too expensive but with enough capacity that we can add a third panel (which we should have space for) if we want to. We had all the parts, including the modules, shipped to a hotel we were going to in Denver (for a business meeting), and made an appointment at a local RV shop to get it all installed.

I would have wondered myself, once, because the popular image is of solar energy just running your electrical devices. Under suboptimal conditions (shade on the panels) we still usually did all right; I would just try to do a bit less work on those days, when I could, or we'd dip into our battery reserve. This warranty states that within this period the module should produce no less than 85% of its rated output. The system will work even in overcast weather conditions, both in the summer and winter months.
Light weight and rugged CamCaddy is the ONLY camera battery charger capable of powering virtually all camera batteries. But the Escapees Forum turned me on to an online solar price survey, which led me to the dealers with good prices.
Sounds good, but there are two major drawbacks: First, if you don't park your RV pointing the right direction, your panels aren't going to tilt the right direction.
In retrospect, I wish I'd split for the more expensive MPPT controller that turns your modules' excess voltage into charging current (more about the voltage later). Their choice of mounting location was also fairly close to our big satellite dish, so if we park the camper pointed north or west, the dish shades the panels. The rated current of our two modules is 14.2A, but the highest I've actually seen is in the neighborhood of 11A.
The laptop computer and satellite modems draw about 6 amps every minute they're on, which in a full workday amounts to about 50 amp-hours. And come the summer, I think we'll be doing finei?? except then we'll either go north (where the sun's lower in the sky) or need to run an air conditioner (which uses so much power that RV rooftop solar is out of the question). But the fact is, you have varying energy requirements over the course of a 24-hour day, and your solar panels are producing energy on their own schedule during the daylight hours.
If I had found this map first, I probably wouldn't have built my calculator, but that's OK – I don't regret it, they serve slightly different purposes.
It has done what we wanted it to, allowing us to go months without plugging our camper in – which in turn gives us much greater freedom of where we can go, essentially where we can live. I got up on the roof with my tape measure, picked out an area in the front corners that wouldn't interfere with our other plans for the roof, and determined how much space we had to work with.
Second, you need to go up on the roof to do the actual tilting every time you park, and then go back up to lay them down when you're ready to move again (unless you can rig up a way do to it from inside). Some members of the class (you know who you are) may want to brush up on their electricity basics. Add another 20Ah or so a day for lights & such in the camper, maybe another 20 for the furnace at this time of year, and about 10 for the camper's phantom loads (fridge electronics, LPG and CO detectors, etc). The battery is a crucial part of this system, because it stores the energy from the panels until you actually need it. When I started asking this question, I had more difficulty than I expected finding any answer at all. Won't the thinner atmosphere in the mountains allow more photons onto the panels (and thus electrons into the wires) than when we're at sea level? However, the longer days generally made up the difference, and we had enough power to live on.
We had enough limitations on parking options imposed by our satellite dish that I wasn't keen to add another, and we move often enough that the thought of climbing up on the roof every few days didn't appeal. So the panels are designed with enough voltage to spare for all of this, but this means that you don't get quite the output current you might be expecting. When you need more than the panels are producing at a given moment, you draw from the battery; when the panels are producing a surplus, they charge the battery. And being winter, we're just not getting that much charge from the panels – maybe 60Ah on a clear day. Classic’s in built LCD data panel provides useful information about battery level, power input and connectivity.
But it's easier to conceptually separate the two systems, and think about your electrical loads drawing out on one side and the panel charging on the other – even though it's a single system with a battery bank in the middle. Throw in a bit of recreational computer use in the evening (like watching a DVD, surfing the 'net, or me writing this article), and we're way over.
