You can still do it best mppt controller 40 amp http amzn to 2ggyi44 best low light sola.
Amorphous solar panel low light.
In a direct comparison with mono or polycrystalline panels amorphous cells outperform them in low light conditions.
Amorphous offers the benefit of operating in lower light conditions and hence is suitable for many applications that are used in lighting since it will be able to put some charge into a battery at a lower light level than crystalline solar panels.
Amorphous is lower cost than crystalline although it s less efficient in converting sunlight to energy and as a result requires a larger panel to deliver the same power as a smaller crystalline panel.
Monocrystalline panels of the three basic solar panel types monocrystalline polycrystalline and amorphous monocrystalline is the most efficient in collecting solar energy and therefore somewhat more effective in regions with low sunlight.
For the portable operator this translates into charging batteries far earlier and continuing to charge them later in the day than operators using mono or polycrystalline panels.
If you are talking about the amorphous shingles don t do it it is basically an entire re roofing the panel cost.
Competition solar 47701 20 watt amorphous solar panel with 8 amp charge controller and 12 volt battery charger by competition solar only 6 left in stock order soon.
Thin film solar are the best solution but stion is hard to get.
