Introduction of Solar Home System

 Solar Home System is composed by Solar Panels, Inverters, Charger Controller, Battery, Cable, Mounting Bracket, which is applied to produce electricity for home use.

Solar Home System is quite suitable product in urban area and the place which is short of electricity. Our Small Solar Home System own great benifits compare with other kind electricity resources:

Electricity generating cost of Solar Home System is much cheaper than diesel engine. Beside low electricity making cost, solar system products also have the features of noiseless, clean energy, environmentally friendly and can access to many different electric appliance.


Working Principle of Solar Home System


The stand alone Solar Home System is an off-grid solar system which uses batteries to store the solar energy. Stand alone solar system solutions design for those who are not able or willing to connect to electricity grid.


However, our on-grid solar home system can be connected to the grid for utilization of grid electricity power. Our solar system can add relative equipment as our customer’s requirement which have the function of switching to city electricity automatically. The solar system can use battery power in priority, if sunshine is not so good or loads consumption is too high which cause battery power insufficient. Then system can switch automatically to grid power supply. Meanwhile, the system can charge the batteries with grid power until batteries are fully charged. Then the solar system will switch back to battery power supply.

Q:Rooftop solar system
2013 PV industry in Europe and the United States antitrust investigation, overcapacity led to the collapse of a large number of photovoltaic industry in Zhejiang, solar prices have fallen. This can be checked at any time online
Q:Solar PV systems
Fourth administrative department of energy of the State Council is responsible for the distributed photovoltaic power generation planning guidance and supervision and management; the local competent department of energy under the guidance of the State Council department in charge of energy, to supervise the construction of distributed photovoltaic power generation planning, the area; the national energy administration agencies shall be responsible for the supervision of the area of distributed photovoltaic power generation planning and policy implementation, network operation, the market fair and safe operation.
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 photovoltaic system
To search and collect profit (in all spontaneous terms): the average recovery of funds on average generating capacity = * (distributed generation electricity subsidies + residential electricity price =200* (0.42+0.55) =194 were the first year of the recovery of funds = daily recovery funds *365=194*365=70810 yuan investment recovery period = total investment / average recovery of funds is about =450000/70810=7.06 years. 6.5 years 25 years average annual net income = recovery funds * (20 -6.5) + daily average generation price *365 * electricity days *5 years =70810*13.5+200*0.55*365*5=1156680 yuan
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: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: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 is the system voltage of solar panels
Solar panels are the most basic components of photovoltaic power generation systems and products. Its main role is to convert solar energy into electricity stored in batteries.
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:What are the components of the solar photovoltaic system?
EVA: a high quality EVA film with a thickness of 0.78mm, which is made of UV resistant agent, antioxidant and curing agent, is used as a sealing agent for solar cells and a bonding agent between glass and TPT. High light transmittance and aging resistance.
