Why choose our solar panel is you ideal choose?

1. The important raw material, Solar cells, come from domestic public company and Taiwan famous company. Quality assurance: 25 years long life span, Industry leading power output warranty 10 years 100%, 20 years 95%, 25 years 85%. 

There are some company which select inferior solar cells that are processed from recycled silicon material from small workshop, so their solar panel service life maybe less than 5 years because inferior solar cell power reduce much more every year.

2. Our company has automated production line for solar panel. Good technology, good quality assurance. Strong production ability: 300 pieces 300w solar panels can be manufactured per day. Most of company weld solar cell with artificial manual work. Bad manufacturing technique is difficult to keep consistency of products.


Q:our school spends around $0,000 dollars on energy.we want to know how much money would installing solar panels on the roof save our school.
What you are really looking for is ROI. Return on investment. If you spend 0K up front how long will it take to recoup that 0k. The answer is too long. Solar panels are not and never have been about saving money. They are about trying to save the planet. So if your school wants to go green then they should do it but the overall cost will be higher.
Q:Can solar panels be installed on water pumps?
Yes, solar panels can be installed on water pumps. This allows the pumps to operate using renewable energy from the sun, providing an eco-friendly and cost-effective solution for pumping water.
Q:How do solar panels affect the overall energy security of a building?
Solar panels can significantly improve the overall energy security of a building. By harnessing the power of the sun, solar panels provide a reliable and renewable source of electricity, reducing dependence on traditional energy sources and the associated risks of price volatility and supply disruptions. This not only enhances the building's resilience during power outages but also helps to stabilize energy costs in the long run. Additionally, solar panels contribute to a more sustainable and environmentally friendly energy system, reducing carbon emissions and mitigating the impact of climate change.
Q:Can solar panels be installed on streetlights?
Yes, solar panels can be installed on streetlights. They provide a sustainable and cost-effective solution by harnessing the sun's energy to power streetlights, reducing the dependence on traditional electricity sources and lowering overall energy costs. Additionally, this renewable energy option helps to reduce carbon emissions and promote environmental sustainability.
Q:are there solar panel that work without the sun?
Unfortunately, okorder
Q:What makes them stop working after a while?
could be temperature, poor design and U-V damage If they are outdoor lamps like mine it is more likely the rechargeable batterys are bad.
Q:I was looking at thin flexible solar panels as solar panels 500w a option to upgrade a 20w solar panel I have permanently mounted to the roof of a home made camper van.Why I was thinking flexible is at just 2mm thin they can be glued down and being flexible they will follow the contour of the rounded shape of the roof of my camper (boxy standard solar panel spoils the lines a little)Another reason is no glass to brake when traveling on dirt tracks(though I am surprised mine hasn't broken yet after thousands of km on corrugated dirt roads). Finally there is a weight saving at only /3 the weight or less then a standard glass panel.There are different grades of flex PV some of the more expensive ones are very flexible with extremely thin backing at around .5mm The ones I was looking at are cheaper and at around 2mm with a thin flexible aluminum backing.$250 is about the going rate for 20w OKorder job. Below is a pic of a smaller one 60w or so.Has anyone had any experience with them?

Q:My electric bill per month averages 800 kWh per month. I am looking at 65W solar panels. How many panels would I need to make my bill come to zero? I realize I also need an inverter to convert dc to ac.
There is always a lot of confusion on this question so I built a webpage to show people how to do the math and pick the right system size. Most all public utilities will trade you kWh for kWh and then either settle up with you at the end of the month or every 2 months. So one week you might have all rainy days but the next 3 weeks you have 0 hours of bright sun even in the winter. This means you have no need to put batteries on your system unless you have a lot of power outages. Then you only need a few hours of battery backup power. At most 24 hours.
Q:Can solar panels be used to power a farm?
Yes, solar panels can be used to power a farm. By harnessing the sun's energy, solar panels can generate electricity that can be used to power various farm operations such as pumps, irrigation systems, lighting, and even machinery. This renewable energy source offers a sustainable and cost-effective solution for farmers looking to reduce their reliance on traditional power sources and reduce their carbon footprint.
Q:I am doing a project for school and i need to power a 9v DC motor using a solar panel. Does anyone know places i could get these for not to expensive, and how many volts/watts i would need?
I too want to buy the panels to light up my house.
