• SIKA adhesive for gluing elements that fasten solar parts

Efficient photovoltaic module

SUNBANK 120W monocrystalline solar panel shows excellent electrical and structural properties. Its dimensions, shape and flexible design make it achieve its efficiency when mounted on any type of surface. The dark-colored surface of the panel allows it to better absorb sunlight and return the stored energy more efficient.

MPPT charge controller

A solar charge controller collects energy from photovoltaic panels and stores it in batteries. Thanks to the use of the latest and fastest technology, the MPPT charger regulator maximizes the amount of yielded energy and sends it intelligently to fully charge the batteries in the shortest possible time. Charge controller keeps the battery topped up and in good condition, extending its life.

The MPPT Lumiax Win500 charger allows you to recharge even a badly depleted battery. Works already at zero battery voltage, provided the cells are not permanently sulphated or otherwise damaged.

MPPT vs PWM

MPPT (Maximum Power Point Tracking) regulators optimize the voltage from the solar panels so that the batteries receive the maximum amount of energy. The maximum power point or optimum conversion voltage varies with changes in light intensity, temperature, and other factors. The digital optimization process performed by the MPPT controller quickly finds and adapts to the maximum power point thanks to advanced electronics, microprocessor circuits and complex work algorithms which explains their high price in relation to PWM controllers. MPPT regulators have an efficiency of 93-97% in converting power from a solar panel.

PWM (Pulse-Width Modulation) controllers are significantly cheaper than MPPT controllers, but they have losses of power conversion from the solar panel up to 60%. This is because PWM controllers do not optimize the voltage flowing to the battery, making them a poor choice for larger panels, but with smaller systems the price significantly affects their choice.
