PulseTech Products’ SP-5 compact solar panel provides clean, renewable energy for boats and vehicles when they’re unable to plug into a conventional power source. Half the size of comparable solar chargers with multiple installation options—including an ability to maintain up to 4 12V batteries connected in parallel—the SP-5 replaces the power loss from electrical accessories that occurs even when the ignition is turned off, and its patented Pulse Technology removes damaging sulfate crystals from the battery plates. Its small size enables easy installation on even the smallest surface of your boat that’s exposed to the sun. MSRP $159.95; pulsetech.net
