The steps of making solar technology stubs
Step:1, the walnut tip toward the fire on the fire for a while, and then thrown into the cold water, walnut will split along the seam.2, the suture will break the walnut into two halves.
Or must there be built - in battery? If yes, then use the mobile phone lithium battery can?
Mobile phone battery as an energy reserve, but no 5V output boost function, the same can not charge the phone. If you have bought a solar panel, you can buy a mobile power with the use of
What is the future of solar power
Those who despise misleading consumer advertising! Solar power generating capacity per square meter is about 120W, the cost per square meter 1500 yuan in the area, the greater the lower the price of 2013 the PV industry has been an antitrust investigation in Europe, because of overcapacity in Zhejiang's large solar photovoltaic industry collapse, the price fell down. This can always online inspection recommended the purchase price of solar water heaters each priced at 150-180 yuan according to material, and other costs, the purchase is optimistic about the local power and reliable customer service of solar panels, the size of the group suggested bidding, mainly electric power and storage equipment is very expensive, the highest conversion rate in 17%-20% efficiency is very low now, as the plant photosynthesis national clean energy, photovoltaic power generation policy is more than 10kW can free grid, but the recovery price is very low, cumbersome.

Buy solar water heater mainly look at what?
Second, liner thickness. The quality of the liner determines the life of the water heater, if the water tank, the water heater will be scrapped. Major brand manufacturers use thickness of not less than 0.5mm of SUS304 food grade stainless steel liner. Argon arc welding is adopted to ensure the service life can reach more than 15 years. Other brands of water heaters in the liner between 0.2mm-0.4mm, the use of a period of time there will be water leakage problem. Therefore, consumers in the purchase of products must ask the thickness of the liner. At the same time, but also beware of patch water tank, the water tank liner is made up of a number of scrap steel belt, the entire inner bladder welding as many as dozens of times
PV solar products market sales
The roof of photovoltaic power generation is less than 2 million monthly sales tax, in accordance with the provisions of the national taxation policy, power users need to provide sales invoices to the power supply enterprise, the buyer also need invoice offset the cost, and the personal power does not have the qualification of business owners, led by invoices complicated procedures. More than 20 thousand of the tax can not get the invoice, it increases the difficulty of the sales of power generation households, is not conducive to promotion. The State Administration of Taxation issued, will reduce the tax burden on household electricity."According to the State Administration of taxation documents, since July 1, 2014, the national Power Grid Corp to buy power products distributed photovoltaic power generation project, by the national Power Grid Corp invoices, monthly household electricity generating sales of more than 20 thousand products, owned by the national grid enterprises in accordance with the taxable amount of the 50% generation of vat. The monthly sales of less than 20 thousand yuan may be exempt from vat.
In the domestic high temperature solar energy collector can achieve how many degrees, the existing product and the technology form?
The tower system, Zhongxingpengyue pattern, looks very spectacular, is the image project of solar thermal power generation love. Its size is limited to 10~20 megawatt level, the use of special, very limited usefulness. The tower system operating temperature 600~1000 degrees Celsius, there are several foreign demonstration projects, the home also has heard, but I do not know the specific progress to that stage, both at home and abroad have not heard of commercial operation successfully.Dish type system, the operating temperature of 700~1400 degrees Celsius, stand-alone dozens of kilowatts, the system 5~25 mw. Due to the small machine, a large number of prototypes developed at home and abroad, but also did not hear of a successful large-scale commercial operation example. Due to the use of Stryn hot gas engine, its manufacturing technology requirements are high, greatly limiting its development.
How to open solar stores
There is a solar dealer, in the local solar market, can be described as a coup. Use the bus as a propaganda tool, bus station, the first sentence is: "a certain store solar power station to remind you:" in the caption on the bus, he hit the store's telephone and communication; on the phone 114, the opening of the new building signs, banners, and even background cloth Online shopping, playing a certain solar energy store. In view of the store is more than the target customers, the dealer also sent a trick to go back and forth to its store expenses reimbursement, in this way, the customer into the store. With the help of external forces, a good manufacturer of this card. Dealers in the choice to join an industry, have to go through thousands of pick million, so that the industry has the impact of brand agents.
