Absorb Environmental Heat

Hot ambient

Sometimes the biggest threat to a lithium-ion battery pack is not the internal heat generated during discharge, but external heat from solar loading or hot ambient conditions. For outdoor and rooftop installations, the challenge of keeping the battery cool can be significant.

Cheaper Per Cycle Than Lead Acid in Hot Environments
white paper published by AllCell found that in hot environments, lithium-ion batteries have a lower lifecycle cost of ownership than lead acid batteries.  Even though the initial purchase price of lead acid batteries is significantly lower than the price of lithium-ion, when analyzed on a full life-cycle basis lithium-ion batteries are now cost-competitive in moderate climates and lower cost in hot climates.  As solar photovoltaic costs continue to fall, the lightweight, long life cycle, and deep discharge capacity of lithium-ion battery systems will enable a growing range of grid-connected as well mobile, portable, and off-grid products and applications to become economically feasible.
