Schumacher SP-400 4.8W Solar Trickle-Charger ASi : The thin film solar module for all your home, farm, and cabin projects requiring reliable power. The SP-400 is a great choice for Canadians wanting to keep small vehicle batteries charged while not being used, and don’t have the best weather year-round, or sky exposure. Ideal for snowmobiles, ATVs, motorcycles, and SeaDoos.
What’s the attraction?
For our Canadian latitudes, thin film solar panels work great. Better than crystalline when the sun heads south for the winter. Why? Thin film Amorphous Silicon solar cells (Powerfilm AS & P3 CIGS cells too) are more sensitive to sunlight, so they start charging your batteries earlier in the day & stay charging later in the evening that crystalline. Crystalline may be more efficient, but that only means a smaller panel for the same power in direct sunlight. A 2W thinfilm solar panel will produce more watt-hours than an 2W crystalline over the course of any day of the year… they just take more room on the roof.
So, if you want more reliable charging in all clear & cloud-cover conditions, go with thin film for your smaller projects.

Recommended to Complete Your Solar Power System…
Should you use a charge controller?
There is no charge regulator included with this kit. For most applications, and battery banks, this solar charger will only maintain, and will not have the power to ‘charge’ the battery. At the operating voltage of this module, this is considered a ‘self-regulating’ solar panel.
If you want the peace of mind, we recommend the 7A model from P3 Solar, and it comes pre-wired with the SAE connectors for fast & easy set-up
