Complimentary fishing

The complimentary fishing project brings the fishing industry and solar power generation together through installing solar panels on the water and planning a fishing farm under the water. When farming and power generation are achieved together, it realizes dual use for one area, dramatically improving the usage efficiency of the area, as well as increasing the output per unit area of land.


Like the photovoltaic greenhouse, the complimentary fishing model is suitable for special farming. Because the placement of solar panels in the fishing ponds reduces the amount of light, it is suitable for farming special kinds of fish that do not like sunlight. Apart from this, the solar power generation can be directly used for the energy of the farming, reducing the farming costs.


Compared to other sorts of distributed photovoltaics, complimentary fishing has another advantage: since the power station is placed on the water of the fishing ponds, the ambient temperature of the surface of the water is lower than that of the surface of the earth, and the spacing between the components is larger than that of conventional power stations, thus forming good sunshine, ventilation, and a cooling environment. This extends the life of the photovoltaic power generation components and improves the power generation efficiency.


Agricultural greenhouse advertisement

The photovoltaic greenhouse is a new model of distributed photovoltaic applications. Compared with the construction of large-scale centralized power stations on the ground, the photovoltaic greenhouse project has a lot of advantages.


First, the photovoltaic greenhouse uses the roof of greenhouses, so that it does not cover land and does not change the nature of the land usage. Because of this, land resources can be saved. Second, by placing solar panels with different transmittance of light on the roof of the greenhouse, the lighting needs of different crops can be met, and organic agricultural products, precious seedlings and other high-value crops can be planted. Anti-season planting and quality planting can also be realized. Finally, using the power generated on the roof of the greenhousethe energy needs of the greenhouse can not only be met, but the remaining energy can also be sold to the grid, increasing the benefit.


Compared to traditional agriculture, the photovoltaic greenhouse puts more emphasis on technology and science elements, and focuses more on management and the improvement of quality for the workers. As a new model of agricultural production management it will become a supportive industry that can increase the regional agricultural efficiency and the farmers’ income, while leading the promotion and implementation of regional agricultural technology skills through realizing agricultural technology and industrialization.Because of this, the photovoltaic greenhouse can not only effectively make use of the solar energy resources, producing clean and green energy, but also achieve efficient cultivation, providing a new path for green agricultural production.


Commercial roof advertisement

The commercial and industrial roof project is the most promising of the distributed photovoltaic projects. According to a report of domestic brokers, distributed power generation on commercial and industrial roofs is already economically viable, with an IRR (internal rate of return) of around 15%.


Apart from the benefits that can be gained from the energy bill, the commercial and industrial roof project has the following highlights:


1.The components on the roof can help to "adjust" the indoor temperature for free. During summer and winter, cooling and warming effects can play.

2.Reduces the emission of CO2. When there is a national carbon emission tax or trade in the future it provides an extra income.

3.The perfect combination of solar energy components and the roof is an effective showcase of aesthetic and social responsibility. 

Residential roofs

According to statistics, our country has over 300 million square meters of high-quality roof resources. If we combine these resources with photovoltaics, we can provide more than 30 billion MWh of energy. This would amount to electricity for 30 million Chinese families for a whole year.


Following the further promotion of national policies, the installed capacity of residential distribution systems is increasing continuously. After installing a small-scale photovoltaic power station at home, one can not only meet one’s own energy needs, but can also supply the national power grid, thus obtaining benefits.


However, a person installing photovoltaic residential distribution systems has also many things to keep in mind.


First, one has to consider the installation location and mountain area of the photovoltaic modules. In general, south-, east- and west-facing roofs are more suitable for installation. For houses with patios or balconies, one can also consider installing a sunroof, carport or awning. Generally speaking, a 1000W installation needs a roof area of 10 square meters. Additionally, factors like sunshine hours, temperature, and strong or weak sunrays need to be taken into consideration for that place.


Second, one also has to consider the personal economic factors, most importantly the return on investment. According to estimates, according to Shanghai’s current situation of sunshine per year, every 10,000 RMB of equipment can generate 1200 kWh of electricity per year. Assuming that 100% goes to the national power grid and that all subsidies are in place, every kWh of energy amounts to approximately 1.30 RMB in benefits, or a total of 1560 RMB in benefits per year. In 6.41 years the costs are covered. Since the general lifespan of photovoltaic equipment is approximately 25 years, after around 10 years everything is a net profit. In the future, the price of photovoltaic equipment will further decline, the conversion efficiency will increase dramatically, and subsidies and other supporting policies will continue to improve. In the long run, installing a rooftop photovoltaic power station is a good investment.

Through the development of new energy technologies, the whole world is entering an era of energy revolution. In this era, new energy technologies become more mature day by day, and the proportion of new energy is continuously rising. After grafting the Internet on to the new energy industry, the big data platform has played a supporting role for the development of the new energy industry. The revenue investment in new energy has become stable, and the risk has become smaller.


GCL has adapted to this change, providing Omni-channel service support for funds willing to invest in new energy, from entering of funds and the holding of funds, to funds insurance and funds withdrawal, making it safe to invest in new energy and achieving higher returns.


GCL has 25 years of experience in the clean energy industry. We continue to favor the development of clean energy, in order to become the largest global provider of clean energy.

Along with the rapid expansion of photovoltaic electricity generators, the level of power station operations and management is a important factor directly influencing the costs of electricity generation.


The main aim of operation and maintenance of power stations is to reduce time spent engaged in inspecting photovoltaic power stations, to comprehensively record the switching operation procedure, accurately assess and resolve breakdown issues, raise the level of the entire operations and maintenance of the photovoltaic power station and its safety management, thereby raising the station’s profitability.


The construction of intelligent photovoltaic powers stations utilises (internet concepts) to efficiently consolidate operational data from power stations and raise calculations and management, to reach the status of "each individual, instantly connected, each takes according to need, with real time interactivity", to assist operations and maintenance personnel to monitor the operational status of equipment at the power station in real time, and also diagnose breakdowns, to finally realise regionalised management, to effectively raise the operational management level and safety management level of the photovoltaic power stations, to reduce manpower costs, this is of irreplaceable utility for the operational management of distributed photovoltaic electricity generation arrays.
