Q:Solar PV systems
Fifth distributed photovoltaic power generation implementation of self occupied, power over the Internet, the nearest consumptive, power regulation, operation mode. The power grid enterprise uses advanced technology to optimize the operation and management of power grid, and provides the system support for the distributed photovoltaic power generation operation. To encourage investment business entities with the same power supply area of the power users in power grid enterprise cooperation in a variety of ways to achieve the nearest consumptive distributed photovoltaic power generation.
Q:Solar power generation system suitable for home, how much is the cost of a set?
Configuration of a household solar power system is about ten thousand to $twenty thousand
Q:I want to install a full set of domestic solar heating equipment does not know how much money to spend, please.
Save 50% equivalent to an annual savings of more than 3300 heating projects; water consumption in accordance with an average of 200 liters a day, remove the winter has been deducted 120 days, the remaining 240 days probably with hot water total: 48 tons, natural gas energy is calculated according to the cost of the cheapest words per ton of hot water heating costs 15 yuan, annual water savings of 720 yuan. Two of the total savings of 4000 yuan, according to the energy prices coefficient is estimated at less than 10 years to recover the full investment, another ten years of savings more than 40 thousand yuan.
Q:What are the advantages and disadvantages of small-scale solar power generation system?
Solar power has no moving parts, is not easy to damage, simple maintenance, especially suitable for unattended use; solar power will not produce any waste, no pollution, noise pollution, no adverse effects on the environment, is the ideal clean energy; solar power system short construction period, convenient and flexible, and can according to the load or, add or reduce photovoltaic capacity, avoid waste.
Q:Household solar photovoltaic power generation system connected to the grid, how much money?
Sold to the power supply bureau 0.45 yuan once, the state subsidy fee of $0.42, a year issued 3000 kwh.
Q:Solar power generation system how to choose?
The whole system is not equal to the power generation capacity of solar panels, but the system capacity. There are often many manufacturers to promote solar power generation efficiency how high how high, but if the choice of the circuit design and the inverter, loss of power is also completely different. For example, the centralized inverter for series system design, the efficiency of the system is about 88%, each brand inverter is also different. The advantage is that the inverter series system competition brand, low price; drawback is the solar panel is connected in series, the solar panels generating capacity of the whole system by the minimum power capacity decision, so once the board has not completely clean the ash layer is not uniform, or falling leaves or cloudy, the efficiency of the whole system will decrease.
Q:What are the main features of solar photovoltaic systems
Compared with the commonly used thermal power generation system, the advantages of photovoltaic power generation:No danger of depletion; safe and reliable, no noise, no pollution, absolutely clean (pollution-free); not subject to geographical distribution of the resources, can take advantage of the building roof; for example, areas without electricity, and complex terrain area; no fuel consumption and the erection of transmission line can be on-site power supply high quality energy;; users emotionally receptive; the construction period is short, get energy to spend a short time.
Q:What are the devices needed for PV systems?
Solar photovoltaic power generation system is mainly composed of solar cell matrix, controller, battery, inverter and other equipment
Q:Solar power generation system installation which precautions, ah, there is a need for special attention
Pay attention to the basic power calculation is not enough! The reality is not up to
Q:What is the system voltage of solar panels
System voltage refers to the number of solar panels composed of a solar power generation system, the maximum DC voltage of the power system.
