Benefits of Solar Power:

Now is a great time to go solar and harvest the power of the sun. Here is our top ten list of the benefits to installing solar power:

1, When installed, solar energy is free – no resources are consumed
2, Help to lessen our dependence on heavily polluting coal power stations
3, Fossil fuels can't last forever, future generations will appreciate the effort
4, You are gaining energy independence - add battery backup power for even greater energy security
5, The cost of electricity is only going to rise – insure against that rising cost
6, Quality solar power and water adds value and appeal to your home
7, Solar PV systems are easily upgraded in future - aim to make your house a net energy producer!
8, Solar panels offer a long lifetime of low maintenance service, maybe 30-40 years
9, Your friends will think you're great!

10, You'll feel great for doing your bit for the environment!

Q:Solar PV systems
Second distributed photovoltaic power generation refers to the user in the vicinity of the site or the construction of the operation, to the user side of the spontaneous use of their own, the excess electricity and the balance of the distribution network system for the characteristics of the photovoltaic power generation facilities.
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
Q:Rooftop solar system
Recommended to buy solar water heater price per price in the 150-180 yuan, including in accordance with the material and other costs, buy a good look at whether there is a reliable after-sales
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?
There are intermittent and random ground application, power generation and climatic conditions in the night or rainy days have little or no power; lower power density, under standard conditions, the solar radiation intensity on the ground received for 1000W/M^2. Large scale use, the need to occupy a larger area; the price is still more expensive, for conventional power generation 3~15 times, the initial investment is high.
Q:Solar photovoltaic system
State subsidies for distributed PV policy: distributed generation price subsidies by 0.42 yuan / kWh (subsidies for a period of 20 years), distributed photovoltaic power generation system of power grid, power grid enterprises in accordance with the local coal-fired power by electricity (0.44 yuan /kWh) acquisition.
Q:Solar power generation system how to choose?
To choose the right, we must first understand the composition of the system and the core of the power generation. Solar power system consists of solar panels or solar module, inverter, bracket, distribution box, cable and other accessories. The core components are solar modules and inverters, which directly determine how much electricity is generated and how many years to come. 5KW system, in the summer when the maximum amount of light radiation can be issued 23 days a day or so.
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:How to calculate the income of photovoltaic system
There are two kinds of algorithms, one for the total solar energy and the total electricity consumption, a solar photovoltaic power generation in real-time and real-time electricity.
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.
