Go Power 500W Solar Flex Kit - 500-Watt Flexible Solar Kit (GP-FLEX-500)

 Go Power 500W Solar Flex Kit

Go Power Solar Flex solar panels are designed to provide a powerful charging solution for boat batteries. Unlike other ‘thin’ products, Solar Flex panels use high-efficiency monocrystalline cells that produce more power per square foot than any other flat panel on the market. 

An impermeable lamination coats the entire module, allowing the Go Power 500W flexible solar panel to flex against curved areas, eliminating any need for a bulky frame. The flat, lightweight module is less than 1/8 inch thick and provides an extremely durable surface. The panel can be affixed by adhesive or screw mounting options and quick-connect MC4 cables are an added bonus for ease-of-installation.

Solar Flex panels are aerodynamic and durable - a virtually unbreakable solar battery charger.

How Does This Go Power Solar Charging Kit Work?

Go Power Marine Solar Power Panel


The Flex-500 solar panel absorbs the sun's energy and converts it into DC electricity, and this electricity charges the battery. The battery stores the electricity, similar to a water tank storing water. This battery power may be used at any time to operate DC-powered devices connected to the battery. To increase the battery service life, a solar controller is used to prevent the solar panels from overcharging the batteries.

Everything needed to provide solar power onboard is included in this kit:

  • 5x GP-FLEX-100 Watt Solar Panels (totaling approx. 500 Watts / 28.4 amps)

  • 40-Amp MPPT Solar Controller (GP-MPPT-40)

  • MPPT Digital Remote Display

  • 1 x GP-CEP-25 – 25’ Cable Entry Plate with 25’ of cable

  • Mounting hardware (4 x GP-MH-4-KB)


40-Amp MPPT Solar Controller (GP-MPPT-40)

Go Power GP-MPPT-40 Controller

The Go Power! 40-Amp MPPT solar controller maintains the life of the battery by protecting it from overcharging. When your battery has reached a 100% state of charge, the Controller prevents overcharging by limiting the current flowing into the batteries from your solar array.

The GP-MPPT-40 optimizes solar charging capacity in mobile systems in all sun and tilt conditions while allowing the use of simpler series wiring configurations up to 150V (Voc @ STC).

Features of the GP-MPPT-40:
  • Maximizes all power from your solar modules

  • Charges 12/24V Batteries with higher voltage arrays

  • Stackable: add an additional controller for 80A
  • Innovative current-mode control reacts faster to changes in sun conditions than competition

  • Easy-to-read backlit digital remote display
