The prospects are very good and may even receive state subsidies. Usually before investing, you must first understand the development prospects and costs of the project, and then you can start the project with good development prospects and a cost acceptable to investors. Investment prospects of solar energy: At present, whether oil, coal or other fuel energy is non-renewable, pollution will occur during use, but the damage to the environment is relatively large, but solar energy is different. Pollution-free recycling is a kind of clean energy that can help us continue to develop. It can be said to be one of the directions of future development and will always be supported in the future, so the investment prospects of solar energy are still very good.
Solar cost: Solar cost includes the total cost of each component of the system, installation and maintenance costs over the life of the system. The most expensive investments in general are solar offices and inverter panels. Each manufacturer's production price is different. At present, the market price is tens of thousands to hundreds of thousands, and the cost per watt is usually eight yuan. The specific investment cost should be determined based on the actual installed equipment and labor costs.
The National Development and Reform Commission and the National Energy Administration have issued the "Notice on Actively Promoting Subsidy-free and Affordable Grid Access for Wind Power and Photovoltaic Power Generation" on the official website of the National Energy Administration (Explanation) Regarding whether funding will be received in 2019. Says: Promoting low-cost) Internet projects will not immediately end grants for all new wind and solar projects. At this stage, affordable (low-cost) online projects without subsidies are mainly carried out in areas with good resource conditions and guaranteed markets. At the same time, in areas where subsidy-free Internet access is not possible, construction will continue to be carried out in accordance with the policies and management requirements for competitive allocation projects issued by the National Energy Administration. But the project will cut power through competition that will significantly lower electricity prices.
In addition, it is pointed out that local energy authorities at all levels and other relevant departments can issue local subsidy policies within a certain period of time, and projects that only enjoy local subsidy policies are still considered affordable Internet projects. The "Notice" also refers to wind and solar-scale (low-cost) Internet projects that have been approved and are due to start and launch before the end of 2020. During the validity period of the project, the support policies related to the Notice will not change.
Is solar photovoltaic power generation equipment expensive?
Small renewable energy power plants include biomass (agricultural and forestry waste) direct combustion or gasification power generation, biogas power generation, Solar photovoltaic power generation, wind energy, small hydropower, geothermal power generation, etc. Affected by the environment, geographical resources, construction costs, etc., the scale of this type of power plant generally cannot be made too large. According to the practice of the power industry, the cost is expressed in unit cost yuan/kw. Environmental conditions vary from place to place, and the cost also varies. The smaller the installed capacity, the higher the unit cost, but there is a general rule.Spectrum:
Biomass energy (agricultural and forestry waste) direct-fired power plant: 8,500-10,000 yuan/kw
Biomass gasification power generation: 11,000-15,000 yuan/kw
Biogas power station: 9000-30000 yuan/kw (the cost of imported equipment is higher)
Solar photovoltaic power station: 8.5-10 yuan/Wp (photovoltaic power stations are generally small, with Wp- —Feng watt means, can be understood as watt)
Wind power: 8500-9000 yuan/kw
Small hydropower: 8000-12000 yuan/kw
Geothermal energy Power station: 12,000-15,000 yuan/kw
From a cost accounting perspective, it is very cheap compared to thermal power, hydropower, and wind power. First of all, thermal power, hydropower, and wind power must be selected in areas that do not affect social activities, and are subject to geographical restrictions, so a long power grid must be built. Solar photovoltaics can be installed as long as there is a suitable free space, and can even be installed on the roof of a building and connected to the grid. Extremely convenient and low cost. Secondly, compared with thermal power, hydropower, nuclear power and other power generation equipment, solar photovoltaic power generation equipment is very simple, and the cost is also much lower considering factors such as construction difficulty and construction period. In addition, solar photovoltaic power generation equipment is relatively simple to maintain. Even if there is a problem, it is a local problem. There is no need to stop production for maintenance, and the operating cost is also very low. Therefore, for large-scale power generation equipment projects, solar photovoltaic power generation equipment is not expensive. If it is household distributed power generation equipment, it should be considered from the perspective of cost recovery. Generally speaking, the cost can be recovered in 5-7 years, and the service life is more than 30 years. Even if it is regarded as an investment, it is a choice with an ideal return rate.
