An on-grid solar system, also known as a grid-tied solar system, is a solar power system that is connected to the main electrical grid. This type of system uses solar panels to generate electricity from sunlight and sends any excess power back to the grid, often in exchange for credits or payments from the utility company. In an on-grid solar system, when the solar panels produce more electricity than is being used in the building, the excess power is sent back to the electrical grid through a bi-directional meter. Other customers on the grid can then use this excess power, and the owner of the solar system may receive a credit on their electricity bill or a payment from the utility company ( According to SREDA , Owner can put 70 % Solar Plant (AC) of sanction load to enjoy energy export facilities as per net metering facility-2018 .
A few years ago, it was uncertain whether wind energy could be a potential energy source but some recent statistical analysis by SREDA and some foreign donors, it is believed that Bangladesh has significant potential for wind energy due to its long coastal belt and the presence of hills and valleys in the northern regions of the country. In a recent survey conducted by a Chinese company revealed that the mean wind speed at 120 m height was 5.466 m/s at some of Upozilla of Patuakhali. The Bangladesh government has set a target of 1370 MW of electricity generation from wind power by 2030.
To invest in Wind Energy, a proper feasibility study is required as per standard IEC-614001 considering Infrastructure development of the target site , national grid availability and so on. EAI is capable to conduct the feasibility study with financial modeling.
