The SOLAR 40 Battery Charger System is designed as an expandable system for those looking for power independence but unsure of their power requirements.

The system is designed around the 40W MASTER panel and the high specification Power Controller which allows the addition of up to three 40W ADD-ON panels to give a maximum capacity of 160W.

Once the 40W MASTER panel is installed, 40W ADD-ON panels simply glue into place, no special tools or drilling of holes is required.

The 40W ADD-ON panels come fitted with the female link cable with integrated waterproof cap, plus 3 metres of male link cable which allows maximum flexibility when locating additional panels on the roof.

How Solar Works

Solar energy is a tried and tested power source that is already being used around the world for numerous commercial, industrial, government and domestic applications. It is powering water pumps in African villages, weather stations in the Antarctic and satellites in space!

It works by transforming the energy from the sun into a reusable form of electricity, a process known as Photovoltaic (or PV for short). Your Solar panel acts as a collecting tray, helping you catch the sun’s rays. The bigger the panel, the more energy you can collect. The energy collected is stored for your future use in a battery.

Sometimes you collect more energy than you actually need so with larger panels a voltage regulator should be fitted to control the flow of energy and prevent battery damage.

It would be hard to find a more environmentally friendly power supply. Clean and green, solar power is a renewable, sustainable and non-polluting source of energy. It is easy to see the appeal of solar power for domestic use. Low maintenance and long lasting, it is a highly cost-effective and reliable energy supply.
