Mark Arnold Electrical Engineering delivers sustainable energy solutions. Solar power remains the most secure source of energy for the future. Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). A photovoltaic convert light into an electric current using the photoelectric effect. PV has initially been used as a source of electricity for small and medium sized applications, from the calculator powered by a single solar cell to homes powered by an off-grid rooftop PV system. As the cost of solar electricity has fallen, the number of grid-connected solar PV systems has grown into the millions and utility-scale solar power stations with hundreds of megawatts being built. Solar PV is rapidly becoming an inexpensive, clean, carbon-free technology to harness renewable energy from the sun. Our competent installers will gladly advise you on all solar technology matters, help you to choose the system that’s just right for you, and after the installation will offer a comprehensive service.
