Solar Photovoltaic (PV) is a technology that converts sunlight (solar radiation) into direct current electricity by using semiconductors. When the sun hits the semiconductor within the PV cell, electrons are freed and form an electric current.

Solar PV technology is generally employed on a panel (hence solar panels). PV cells are typically found connected to each other and mounted on a frame called a module. Multiple modules can be wired together to form an array, which can be scaled up or down to produce the amount of power needed.

An inverter changes DC power from a battery into conventional AC power. IE. From your battery (DC) to your main supply (AC).

A Pure Sine wave inverter produces cleaner power and will not damage your equipment, whereas a modified sine wave can do long term damage to your appliances and some appliances may not work at all.

A good inverter will have the following:

• Pure sine wave
• At least 3 stage battery charge control
• Depth of Discharge control
• Overload capability
• Adjustable charge control
• Seamless change over

This is totally dependent on the peak load that is needed. It is important to do a proper load analysis when deciding what size inverter is needed.

Solar panels rely on sunlight to produce power. On a cloudy day there is a lot less sunlight however the panels will still receive some sunlight and will generate between 10 - 25% of the capacity depending on the density of the clouds.

The solar geyser is installed at a higher plane than the solar collector. The basic principles of physics come into play where a liquid is heated it becomes less dense and rises, creating a thermosyphon circulation of the liquid between the solar geyser and the solar collector.
