Q:Rooftop solar system
Solar panel power generation, then the proposed size of the proposed group, mainly the power substation and storage of electrical equipment is very expensive, the highest conversion rate in the 17%-20% efficiency is very low, not as good as plant photosynthesis
Q:I want to install a full set of domestic solar heating equipment does not know how much money to spend, please.
This area of solar heating system is divided into 4 parts: solar panels. Thermal energy water storage device. Thermal converter. Auxiliary heating wall. This system can be added with winter heating of buildings above 50% hot heat as a heat source for heating indoor floor heating systems, the spring and autumn three season can use gas or not using gas assisted heating (heat storage water tank can not increase the gas heating can be all-weather hot water).
Q:How about the price of solar power generation system
Himin Solar Photovoltaic, as the industry leader, the standard of the pioneers, adhering to industry responsibility, the pursuit of quality is the core, excellent products, is the commitment to the customer. At the same time, Himin photovoltaic products in the development process, realize the function of just one hand, and the pursuit of beautiful, practical and aesthetic products will be fully integrated, highlight the taste is Himin has been adhering to the brand concept.
Q:Solar power generation system installation which precautions, ah, there is a need for special attention
7, the battery terminal to be strong (10 million can not be short circuit) to pay attention to the polarity of installation, to avoid the explosion and fire. 8, the controller has the corresponding distribution protection measures. But the wiring process should also pay attention to prevent polarity reverse, short circuit, etc.. Avoid unnecessary trouble. Pay attention to the angle of placing and avoid the rain. 9, with inverter system, inverter connected to be connected to the battery positive and negative poles. 10, the construction site must be open, in the installation of solar cells can not be tall buildings or other things blocking the sun. 11, the controller needs to choose low loss, good stability, long life controller. When the installation is clear that the controller is a common negative or common cathode design, so that the entire system connection, installation help.
Q:How to calculate the income of photovoltaic system
Photovoltaic panels can only generate electricity, storage batteries need to match. The peak power output of photovoltaic panels = peak wattage X local sunshine time X efficiency coefficient of general domestic parts of the sunshine time is 4 hours (per day), the efficiency of PV system with battery is about 0.7. That is to say, 1000W system, the average daily electricity is about 2800WH (2.8 degrees) or so in accordance with the distributed PV subsidy of 0.35 yuan / degree, solar photovoltaic power generation more than the Internet how exactly?
Q:Solar PV systems
Third to encourage all types of power users, investment companies, professional contract Energy Service Companies, individuals as a project unit, investment and construction and operation of distributed PV projects.
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: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: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:What are the components of the solar photovoltaic system?
Photovoltaic system is composed of solar cell array, battery, charge and discharge controller, inverter, AC distribution cabinet, automatic solar tracking system, automatic solar module dust removal system and other equipment. The equipment is in the light (either sunlight or other light generated by the light) case, battery to absorb the light, the two ends of the cell appeared heterocharge accumulation, namely "photo voltage", which is "photovoltaiceffect". Under the effect of the photovoltaic effect, both ends of the solar cell produce electromotive force, which converts light energy into electrical energy, which is an energy conversion device. Silicon solar cells are generally divided into monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells three
