It's main operating model is to place the solar equipment purchased by investors in public places such as commercial streets or airports, and distribute the profits to investors. When you buy the equipment, it will work for you for a week, a month, six months or a year depending on the tenor you go for and bring you benefits. From now on the equipment is owned by our company, it will work for the company for many decades years, that's why we need to get more customers to invest.
