Advantages

Reason:

We enjoy exclusive channel to get stock solar panels at more competitive price from Trina,Hanwha,Yingli,LDK,Suntech etc.

These panels are from tier 1 solar panel manufacturers,such as Trina,Hanwha,Yingli,LDK.They are assembled with all grade A materials,only problem is that they has slight appearance defect,but due to their strict quality control,even the negligible defect will lower its grade.so they put these panels into stock.

Quality

These panels adopt all grade A materials,such as solar cell,EVA, back sheet, junction box, glass,frame,connector etc.

They have same electrical performance with grade A solar panels,only difference is the negligible superficial defect.

Poly Solar Panel 250W in China with Full Certificate

Q: if i have a 0 Watt solar panel what does that mean. does that mean it will charge a battery 0 watts per hour? Lets say i hook this up to a car battery and use the car battery to run computer stuff. How much will this charge the battery?: It will be less than a trickle charger on the battery. It is about .85 amps at 2 volts dc.

Q: Can solar panels be used for charging electric bikes?: Yes, solar panels can be used for charging electric bikes. Solar panels convert sunlight into electrical energy, which can be stored in batteries or directly used to charge electric bike batteries. By utilizing solar power, electric bike owners can harness renewable energy to charge their bikes, reducing their reliance on the electrical grid and promoting sustainability.

Q: can this amount of solar charge these batteries.: Well you are stating the solar panel powers but no mention of their voltage??. Yes, they should do the job. I suspect the lack of blocking diodes may be your problem, assuming you have done the homework. You have 6 battery cells at 2 volts each, that is ...err..2 volts, assuming you have them connected in series. Count the number of cells on the solar panels and maybe we have a starting point. One solar cell is 0.6 v, in this case you would need a minimum of around 30 cells (physically it will probably be 32 to make it 'square'), you need a fair bit of over- sizing in that direction. Solar panels are resistive when not illuminated so must have a blocking diode included to prevent the batteries from discharging into the solar panels at night. Check that each array has a blocking diode included, if not add them. Solar power is pretty useless unless you have loads of sunshine. You seem to have gone through a bit of trouble and expense on this one, so give me some basic facts and I will help you through it. Update 7 Dec If the batteries take 20 hours to fully charge and there are 0 hours of sun each day then the batteries will be fully charged in 2 days. The question was, can the battery be charged, answer is yes, it can. There is no mention of load. If the batteries are not charging there is something wrong.

Q: Are there any safety concerns with solar panels?: Yes, there are some safety concerns associated with solar panels. These include the risk of electrical shock during installation or maintenance, the potential for fire hazards due to faulty wiring or overheating, and the handling of toxic materials during the manufacturing and disposal processes. However, these concerns can be mitigated through proper installation, adherence to safety regulations, and use of high-quality components.

Q: Can solar panels be installed on a university campus or educational facility?: Yes, solar panels can be installed on a university campus or educational facility. In fact, many universities and educational institutions have already embraced solar energy as a sustainable and cost-effective solution for their energy needs. Installing solar panels not only reduces the environmental impact of the facility but also provides an opportunity for hands-on learning and research in renewable energy for students and faculty. Additionally, it can help save on energy costs and provide a reliable source of clean energy for the campus.

Q: Can solar panels be installed on a condominium or apartment building?: Yes, solar panels can be installed on a condominium or apartment building. However, it may require certain considerations such as the availability of suitable roof space, permissions from the building owners or management, and potential impact on other residents. Additionally, installation and maintenance costs may need to be shared among tenants or considered in the building's budget.

Q: Can solar panels be used in areas with high levels of lightning activity?: Yes, solar panels can be used in areas with high levels of lightning activity. However, it is important to install proper lightning protection systems and grounding measures to minimize the risk of damage or electrical surges caused by lightning strikes.

Q: Can solar panels be used in areas with high levels of shade or obstruction?: Solar panels can still be used in areas with high levels of shade or obstruction, but their efficiency and power generation may be significantly reduced. Shadows or obstructions can cause partial or complete shading on the panels, which can lead to a decrease in energy production. However, advancements in technology, such as the use of microinverters or power optimizers, can help mitigate the impact of shading by allowing each panel to work independently and optimize energy production. Additionally, proper placement and angle adjustments of the panels can also help maximize sunlight absorption, even in shaded areas.

Q: How much roof space is needed for solar panels?: The amount of roof space needed for solar panels varies depending on various factors such as the size and efficiency of the panels, the energy requirements of the building, and the geographical location. However, on average, a typical residential solar panel system requires approximately 100 to 400 square feet of roof space.

Q: How many solar panels do you need on your house to power your heater in winter?: You can get over 5 times the efficiency at lower cost by directly absorbing the heat in a solar water-heating collector. Use the electrical panels for making electricity for stuff that needs it.
