Solar panel efficiency is measured in Watts calculated from how much of the sun’s energy a panel can convert into usable electricity, however this is often an unreliable way for consumers to working out which is the best flexible panel to choose for their motorhome.
Our panels are made up of thin solar cells constructed from copper, indium, gallium and selenium which can harvest significantly more energy than a standard flexible monocrystalline panel (when compared solely in wattage size).
The technology is much more efficient at harvesting power in low light. The panels work earlier in the day and later into the evening. The same is true throughout the day, for example if the weather is at all overcast or part of the panel is in shade (as all linked monocrystalline cells stop working if any cell is shaded). This makes our panels more than 17% efficient over glass photovoltaic panels and 60-70% more efficient than an equivalent flexible monocrystalline solar panel.
Most flexible monocrystalline panels are constructed in China and, on top of their inefficiency, they are also notorious for failing after a short period of time. Flexible monocrystalline panels do not cope well in hot weather as they have a tendency to overheat and burn themselves out. Where panels are sold with a 20-year cell warranty, it is often stated in the small print that they only actually have a 1-year manufacturing warranty and failures are normally down to manufacturing.
“Flexible” panels are often still fragile and can sometimes only be flexed a couple of times. If being fitted to a solid structure this is fine. However, when fitting to an elevating roof which will flex slightly every time it is operated, the effect overtime can cause the panel to break and this will not be warrantable. Our panels are fully manufactured in the UK and are designed to be used on commercial roofs that are constantly walked on, and are therefore almost indestructible.
Fitted costs from £660
Please Note that ribbed roofs and bottom terminals may take longer to fit and this time is chargeable at £60 per hour.
For an additional £90 we can provide a solar panel with hidden underside terminals.
