Days with Solar Engineering !

These days I'm working with some solar projects with a company and getting lot of experiences related to the industry. So I thought giving you an idea how domestic solar system works. A solar power systems can be basically divided in to two categories , Grid ties systems and Off grid systems. In Sri Lanka , people mostly use grid tied systems which feeds the generated energy directly to the utility grid. And off grid systems means , solar systems with batteries which are used for locations where utility grid cant reach etc communication towers in mountains , islands etc.

Today I'm going to tell you about grid tied systems , this is what we use mostly. A grid tied system means the solar systems is connected to the utility grid through a net meter to calculate imported and exported energy. This systems are not complex. Normally domestic systems are less than 20kW's.

There are basically two units in a solar systems. Solar Panels , which are used to convert energy from sun into DC electricity and Inverter unit , which convert that DC electricity in to AC electricity. And we directly feed that energy generated through the energy meter to the grid. The bill is calculated based on imported energy by the building and exported energy by the solar system. So it's very simple

This is a really good investment and payback period is less than 5 years for projects larger than 10kW's and for houses which has a large consumptions , this will always profitable when considering the block tariff. I will share more information step by step. I'm really busy with few projects these days. But working to implement this 100% green , environmental friendly systems always make me happy. Thanks for going through my article.

Have a nice day !
