Photovoltaics (PV) is the name of a method of converting solar energy into direct current electricity using semiconducting materials that exhibit the photovoltaic effect. A photovoltaic system employs solar panels composed of a number of solar cells to supply usable solar power.
Power generation from solar PV has long been seen as a clean sustainable energy technology which draws on the planet's most plentiful and widely distributed renewable energy source the sun. The direct conversion of sunlight to electricity occurs without any moving parts or environmental emissions during operation. It is well proven, as photovoltaic systems have now been used for fifty years in specialized applications, and grid-connected PV systems have been in use for over twenty years
All Lighthouse Estate villas are fitted with a 2.0 Kw PV system and allowing for 10% of the power generated by the system to be exported back into the grid, residents can expect to save around $800.00 a year on electricity costs.
Allowing for a 7% per annum increase in electricity cost and the natural degradation of the panels, you could expect to save around $40K over the lifetime of the system.
Each system is also projected to save 3.5 tonnes of carbon in its first year and 87.3 tonnes over its lifetime. As with all aspects of The Lighthouse Estate construction and materials are focused on reducing our carbon footprint.
