1）What is a solar cell / module / array?
A solar cell (also called photovoltaic cell) is a solid state device that converts the energy of sunlight directly into electricity by the photovoltaic effect. Assemblies of cells are used to make solar modules. The grouping of solar modules is referred to a module array.
2）How do the solar cells generate electricity?
The solar cell works in three steps:
1.Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon.
2.Electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. Due to the special composition of solar cells, the electrons are only allowed to move in a single direction.
3.An array of solar cells converts solar energy into a usable amount of direct current (DC) electricity.
3）Why should I use PV?
In recent years, more and more people are realizing the importance of renewable energy, particularly those who are environmentally conscious. PV can supply us with clean and sustainable electricity. It produces no toxic emissions, or greenhouse gases, and causes no hazardous waste. PV systems generate electricity using the Sun's energy, so the ongoing costs are minimal. Moreover, continued R&D means installation costs are gradually being reduced. Some people would rather invest capital on an energy-producing improvement to their property than continually sending money to a power company. Others like the security of reducing the amount of electricity they buy from power utilities, because it makes they are less vulnerable to power outages and future increases to the price of electricity.
4）How durable are the modules?
All Canadian Solar modules have been subjected to and passed mechanical load testing according to standards for IEC 61215 and UL1703. However, we do not recommend stepping or placing anything directly on the modules.
5）Will the solar system still work in bad weather?
Yes, bad weather will affect the maximum power output of your system, but it will still continue to produce electricity.
6）How much electricity will it generate?
The amount of electricity your PV system can generate will depend on a number of factors, such as location, system size, solar resource and module orientation.
7）How long will the modules last? Are they guaranteed?
The typical lifespan of a PV system is more than 25 years. Canadian Solar offers a standard Product warranty of 10 years covering defects in material and workmanship. And a 25 year linear performance warranty. As an added security, Canadian Solarís standard warranty is jointly insured by leading insurance companies (AAA rated) in Europe and USA.
8）How can I learn more about Canadian Solar?
Please visit our web site www.canadiansolar.com to learn more.
9）Does Canadian Solar produce modules according to customersí requirements?
Through years of experience, Canadian Solar has established a highly experienced technical engineering team available to develop and meet all of our customerís needs, including developing PV modules/systems to your requirements.
10）Where are the modules produced?
Canadian Solar has PV modules manufacturing facilities located in China and Canada.
11）How much space do I need for a PV solar system?
The amount of space you will require will depend on a number of factors. For instance, the amount of energy you wish to produce, the panel type and orientation. It will also depend on whether the PV system will be mounted on a roof or the ground.
12）Do I need planning permission to install a solar system in my city?
Yes, generally a build permit is needed.
13）Where can I install a PV system?
PV systems can be located on the ground, the roof of a building, or even into the buildings architecture.
14）How do you fasten modules together?
Please refer to our installation manual available on or website. Click the following link:
15）What direction should the PV system face?
Ideally, a PV system should have an unobstructed south facing view.
16）What kind of maintenance is required on my PV system?
The only maintenance that is required is a periodical cleaning. Overtime dirt and/or debris could build up on the module limiting the amount of energy producing area.
17）Can modules be recycled?
Because the PV industry is still relatively young, there are currently not many facilities that recycle PV modules. Please check with your local authorities to find out if this is available in your region. Canadian Solar is a member of PV Cycle.
