overcoming solar panels’ winter problem
Car manufacturers must consider the effect of cold weather on battery performance before entering the northern market.
Developers of wind farms must be aware of the potential of ice making. -
It depends on the turbine blades and how this may affect maintenance costs.
Ice and snow are not a problem. -
Circuit breakers, but Ontario is not California, which must take into account all purchase decisions and designs.
Each jurisdiction presents a series of challenges that need to be managed.
A research project was held in St. Louis.
Lawrence College and Queen\'s University in Kingston are studying the complex relationship between snow and solar photovoltaic panels.
Of course, it\'s worth knowing.
More than 25,000 solar projects-
From small roof systems to large-scale \"farms\"-
It is expected to be developed in the province in the next two years as part of renewable energy feed. -in-tariff program.
According to the researchers, to my surprise, there are nearly three-
A quarter of the solar photovoltaic panels installed worldwide in 2009 were in countries experiencing some snowfall.
This reflects solar subsidies in Germany, Japan, the Czech Republic and Ontario.
The Queen\'s preliminary study of how snow affects panel performance has revealed some interesting data.
\"The snow effect increases the albedo, which is（positive)
The influence on the properties of panels, \"St.
Lawrence College Center for Sustainable Energy Applications.
Albedo is the ability of a surface to reflect.
We know that snow reflects light.
We know that the dark sidewalk absorbs it, which is why it gets so hot in summer.
\"Although snow on the panels reduces their power output, snow on the ground increases albedo, thereby increasing solar radiation on the panels,\" Barbasola said. He adds that the measurements vary according to the angle and pattern of the panel.
In other words, if there is a lot of snow on the ground around the solar panels, this is sometimes a good thing, because it means that the panels receive more light and may generate more electricity.
Of course, assume that the panel is not covered by snow.
The preliminary study was conducted at a small experimental site in Kingston.
Only 16 panels were monitored, and the installation angles of each panel ranged from 0 to 70 degrees, so the research scope was limited.
A team led by Joshua Pierce, a professor of engineering at Queen\'s University, is expanding its research on these findings and drawing more attention. -
Upgrading Research to Collect Data from Four Sites-
Queen\'s Avenue, Woodbridge\'s Cortridge Center and St. John\'s Street are two attractions.
Lawrence College is one of the most advanced outdoor testing facilities in North America.
Partners in the project include Natural Resources Canada, Chemical giant DuPont Canada and several companies in the solar industry.
\"Few comprehensive studies have attempted to quantify the impact of snow, nor have any studies provided universally applicable snow estimates. \" -
Relevant losses, \"Bassola said.
\"The first objective of snow research is to try to better understand the impacts and provide some suggestions for reducing these losses.
Not every solar panel is equal. Thin-
For example, thin-film solar panels can generate electricity by diffusing light, whereas traditional crystalline solar panels require direct light. Thin-
Membrane panels may benefit more from the albedo effect, so they may be a better choice for areas with larger snowfalls.
In order to maximize exposure to sunlight, while ensuring that snow is easy to slide during and after snowfall, what is the ideal angle of the panel?
Does the loss of performance caused by snow cover, as well as the reduction of electricity revenue sold to the grid, make investment in snow removal worthwhile?
What is the most effective and the lowest? -
Cost removal options?
What is the compensation of albedo effect for snow performance degradation?
Can special, smooth coatings be used to accelerate snow shedding?
These are just some of the questions that researchers want to answer, which is good for Ontario, because you can bet that solar manufacturers in China and California will not answer these questions for us.
