Solar Power

What is Solar Power?

The Sun supplies energy in the form of radiation. Because of the great distance between the sun and the earth only a tiny part of solar radiation reaches the earth's surface. In good conditions this equates to approximately 1000 W/m2. Of this solar cells can only convert approximately 15% (150 watts).

How does Solar Power work?

A Photovoltaic device (generally called a solar cell) consists of layers of semiconductor materials with different electronic properties. In a typical crystalline silicon cell, the bulk of the material is silicon, doped with a small quantity of boron to give it a positive or p-type character. A think layer on the front of the cell is doped with phosphorous to give it a negative or n-type character. The interface between these two layers contains an electric field and is called a junction.

Light consists of particles called photons. When light hits the solar cell, some of the photons are absorbed in the silicon. If the photons have enough energy they will be able to free electrons, the electric field at the junction will cause the electrons to move through the silicon atoms in the cell and into an external circuit as electrical current. As they flow through the external circuit they give up their energy as useful work (turning motors, charging batteries etc) and return to the solar cell.

Energy for Home, Boats, caravans, comercial and specialist applications.

Solar equipment makes it easy to convert the Sun's energy into electricity for various applications including those metioned above. These high performance panels will withstand even the harshest conditions day after day to provide a reliable source of electricity. They are manufactured using high end efficiency solar cells. their textured surface reduces sunlight reflections and increases the yield. Efficient and robust, with salt water resistant aluminium frames, they provide rigidity and protection against the elements. The panels also have a waterproof junction box to allow easy wiring.

The S-Series Solar Panels.

The K-Series Solar Panels.

Solara has designed the K-Series for the Motorhome and Caravan market. It can simply be glued to any flat surface. Due to the panels being extremely thin they are virtually invisible, can be walked upon and are virtually theft proof. They utilize the same crystalline cells as the S-Series and therefore offer the same performance. The panels have a small junction block on top and are supplied with 1.5 of solar cable.
