Solar Power

What is solar Electricity?

Solar power is arguably the cleanest, most reliable form of renewable energy available, and it can be used in several forms to help power your home or business. Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic cells convert light into an electric current using the photovoltaic effect.

That means, Solar-powered photovoltaic (PV) panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun.


How does it works?

The most common way of harnessing energy from the sun is through photovoltaic (PV) panels – those large, mirror-like panels you’ve likely seen on rooftops, handheld solar devices, and even space crafts. These panels operate as conductors, taking in the sun’s rays, heating up, and creating energy (electricity).

Our system works in an absolutely simple and efficient way. Our solar system converts sunlight in to electricity. The current generated from the solar panels is DC [direct current]. To convert the DC into AC [alternative current] which is in the form of national electricity grid, an inverter is used. Inverter is the device that will match the properties of the national grid and connect the solar system with the grid.

Solar panels will generate energy in the day time when the sun is falling on to it. The inverter will convert it to usable alternative current [AC] and connect it to the home main power supply. The generated power from the solar system will be first utilized, if there is any in house usage and the excess power will be fed into the national grid. As the name implies, the solar system is tied with or attached with the national electricity grid, so it is known as a solar grid tied system. At day time the excess power will be fed into the grid after utilized in house and at the night time the power will be taken from the grid. To calculate the energy inflow and outflow a special meter has to be installed from the electricity supplier known as “net meter”.


Benefits of solar..


  • Excellent return on your investment for a typical Solar system the ROI (return on investment) is over 25% per annum.
  • Recover your investment in less than 5 years. Generally the payback period for a typical solar PV system is between 3-4 years in Sri Lanka. This means that you can enjoy electricity bills savings after this period during the rest of the product life cycle.
  • Reduce the risk of volatile electricity bills with produced from your own solar system you are least impacted with increased electricity bills in future.
  • They help reduce air pollution caused by utility companies.

  • Solar power systems help increase something called “peak load generating capacity,” thereby saving the utility from turning on expensive and polluting supplemental systems during periods of peak demand
  • Contributing clean, green power from your own solar electric system helps create jobs and is a great way to mitigate the pollution and other problems produced by electricity derived from fossil fuel
  • Solar-powered electrical generating systems help you reduce your impact on the environment and save money at the same time!
