As a construction company we are bound to design all kinds of construction needs and we excel in these. We design multi storied buildings and infrastructure, highways, pre-feb/ engineered building, storm water drainage, irrigation and drainage and coastal, marine works and many more. We concentrate on essentially on the satisfaction of our customers and quality is the principal of EDCC. Unique and distinct designs created and owned by the company in the construction industry is what leads us to the goal of success.
Just 15min of Sunshine that falls on Sri Lanka has sufficient energy which is equivalent to her entire annual electricity consumption. Yes, you heard it right. If you need another perspective, solar panels installed in just 70% of the area of the island of Karaitivu, will be sufficient to supply electricity for the entire nation. Many have already started harnessing this inexhaustible power source from the sky since 2011 and now it is time for your loved ones back in Sri Lanka to do same to enjoy free electricity throughout the year.
Solar panels are manufactured to generate electricity once they are placed under the sunshine. Electricity generated by solar panels are Direct Current (DC). Appliances at homes run on Alternate Current (AC). Therefore, the DC current generated by solar panels should be converted in to AC current using an Inverter. Electricity generated by the solar panels are fluctuating all the times due to moving clouds at any given time. With such fluctuating currents, home appliances cannot be operated. That is why the inverter output is connected to the Mains. By this way, appliances can be run without any issue. When the sunshine generates more energy than what is consumed, such extra power is fed to the grid. When there is an overcast condition, electricity is imported from the grid in to the home. Solar PV systems are connected to the grid under 3 schemes. They are Net Accounting, Net Metering and Net Plus. More details of these scheme are provided later in this document.
What are the above Schemes?
CEB/LECO allow electricity consumers to connect their solar PV system under 3 Schemes. They are Net Metering, Net Accounting and Net Plus
NET METERING
Solar PV system generates electricity during the day time and feeds both home appliances and the grid. When there is less energy being produced, you will consume electricity from the grid. If there is more energy being produced, it will be exported to the grid. During night time, you can import the exported electricity back. You will have to pay for the net difference. This is measured by the special two-way meter the utility will be installing. If you have an excess electricity in your account, Utility does not pay you. Instead, it will be carried forward to your next month.
NET ACCOUNTING
The system works in the same manner with different electrical configuration. Solar Power is consumed inside home as well as it is fed to the grid. However, when there is excess electricity in your account, Utility will pay you at Rs. 22 per Unit (kWh) in the first 7 years. From 8th year, you will be paid Rs. 15.5 per unit. Since electricity consumers have to pay Rs. 45 for each unit consumed from the grid (if their consumption is more than 180 units per month), this scheme is most suitable for residential consumers.
NET PLUS
Under this scheme, Solar Power is not consumed by the consumer. All the electricity generated will be exported to the grid and will be paid at the same rates like in Net Accounting. This scheme is best suitable for Industrial consumers as they only pay Rs. 12 for each unit consumed from the grid.
