Solar panels and Controllers for small to medium applications.

ChargingChargers.com specializes in small and medium solar battery chargers for applications in 12 volt and 24 volt solar panel systems. We can advise and supply solar solutions for battery maintenance of single or multiple battery packs, or systems with small or intermittent current drains. A solar solution can be appropriate for security systems(video, alarm), remote telemetry, radio repeaters, gate openers, solar fence charger, generator/pump starting batteries, heavy equipment batteries, GPS locators on semi trailers, or as a solar trickle charger and many other situations.

Solar Trickle Charger

Single 12 volt batteries around 80 to 130 amp hours can be maintained with a single 2.5 watt solar battery charger without a controller. The solar panel generates enough current to maintain the battery, but not enough to overcharge it, functioning as a solar trickle charger. The small solar battery charger (1 watt, 2.5 watt, and 5 watt) has a blocking diode built in that prevents feedback through the solar panel at night, which will occur if not blocked. Solar battery chargers over 5 watts (and sometimes the 5 watt) require a solar controller to regulate their output, and prevent overcharging. The solar controller also prevents feedback through the panel at night, like the diode mentioned above. We have a 10 watt 24 volt unbreakable solar battery charger available which we frequently use for maintenance of 24 volt starting batteries on such equipment as generators, large pumps, heavy construction equipment, trucks, aircraft, etc.

UniSolar Panels

We also offer a few selections from UniSolar™ when they are available. The smaller UniSolar panels (64 watts and under) were unavailable or sporadically available for some time, due to the switching of the assembly lines to larger panels for world demand. Now they are available again, though sometimes in limited quantities. Currently the 5 watt US-5, the 11 watt US-11, and the 64 watt US-64 panels are available. These are some of our favorite panels. They are of a proprietary triple layer material, which gathers more usable power from various parts of the light spectrum, and the panels are constructed without a glass front, as the material is bonded to a thin stainless steel sheet, and framed with a durable aluminum frame. This makes the UniSolar panels basically indestructible, and the bypass diodes in the 11 watt and larger panels allows them to function well in part shade conditions. These are long term reliable panels, and we use them in remote locations, portable systems that will be moved or set up and taken down repeatedly, high vandalism areas, and applications where survival is a criteria.

Solar Panel Orientation

A solar battery charger should be oriented to true south whenever possible, tilted at an angle approximating the latitude of the location, adding 15 degrees for winter bias, or subtracting 15 degrees for summer bias. Mobile applications such as semi trailers or emergency response trailers, may require a flat mount of the solar panel, since parking orientation may vary. A solar panel is rated at peak output, which may only occur for 4 to 6 hours per day (or less) depending on the season, and location. These worst case hours are generally used for sizing a solar battery charger or solar system , if the system will be operational during winter months.

The batteries for a solar system should be deep cycle, and are sized in amp hour capacity to accomodate the daily amp draw from the system, with a margin, and usually several days capacity as well, to allow for overcast or other unfavorable solar power conditions. Appropriate lead acid battery types for these systems include the flooded, or wet batteries, absorbed glass mat (AGM), and sometimes the true Gel battery (Gel Cell).
