We have organized several common questions for our clients,may help you sincerely:
1). What’s price per watt?
A: It’s depends on the quantity, delivery date and payment terms of the order. We can talk further about the detail price issue. Our products is high quality with lower price level.
2). Can you tell me the parameter of your solar panels?
We have different series of cells with different power output, both from c-si to a-si. Please take our specification sheet for your reference.
3). How do you pack your products?
We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.
4). How long can we receive the product after purchase?
In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The perfect time of receiving is related to the state and position of customers. Commonly 7 to 10 working days can be served.
What’s a typical solar panel efficiency rating?
Most solar panels are around 11-15% efficient, The efficiency rating measures what percentage of sunlight hitting a panel gets turned into electricity that we can use. The higher the efficiency, the less surface area you’ll need in your solar panels. Although the average percentage may sound a little low, you can easily outfit a typical roof with enough power to cover your energy needs.
What are the most efficient solar panels?
In the lab, scientists have developed solar panels that are 40% efficient, or even slightly more than that. But there’s a big difference between the lab and the real world. Manufacturers haven’t yet figured out how to take these experiments and produce economically viable products. Thinking you should wait for new whiz-bang panels is one of the most common solar myths.
Should I choose the most efficient solar panels available?
High efficiency doesn’t mean better, it just means your panels use less space on your roof. Efficiency isn’t usually a critical concern unless you have an unusually small space for your solar panels. The most efficient solar panels cost a little more, so they’re a less common choice.
Factors that affect solar array efficiency include:
In the U.S., your roof ideally should face south, but a quality design can often compensate for other directions.
Roof and Panel Pitch
The “pitch” or tilt of your roof can affect the number of hours of sunlight you receive in an average day throughout the year. Large commercial systems have solar tracking systemsthat automatically follow the sun’s tilt through the day. These are expensive, however, and not typically used for residential solar installs.
Some panels like it hot but most don’t. So, panels typically need to be installed a few inches above the roof with enough air flow to cool them down. Some photovoltaic panels are designed to be more efficient in hotter climates. Hot temperatures can reduce the efficiency of solar panels.
Basically, shade is the enemy of solar panel efficiency. With poor solar design, even a little shade on one panel can shut down energy production on all of your other panels (like a bad bulb in a string of Christmas lights). Before we design a system for your home, we’ll conduct a detailed shading analysis of your roof to reveal its patterns of shade and sunlight throughout the year. Then, our local installation partner conducts another detailed analysis to verify our findings. This is just one of many reasons to work with a highly experienced solar provider like.
