Snow Tolerant PV Mounting

[bcroe]

Another snow of some 7 inches, nearly 3 feet in Jan. Once again the panels set up for winter in fact completely
cleared themselves with a little sun. I am now going out to clear yesterdays snow from the panels fixed at a
good summer angle. Bruce Roe

Here in January is another example of the advantage of changing the tilt for snow and no snow seasons.
Here is an array fixed in summer elevation, with a typical 4 inch snowfall. The snow is pretty much just
lying there, waiting to be cleared. The gap between levels will make that job easier.

Right across from it are a couple arrays at near vertical orientation, good for both winter production
and snow rejection. Just a swipe would clear them, or the sun would do it before long.

makes sense. Another advantage of adjustable panels; shedding snow in winter.

I can't see the images anymore. File not found ?
edit: nevermind, had to login.

Anyone else have a good tool to get snow off your panels without damaging the surface coating? I like the OPs idea of spacing them out which I will probably try when it gets warmer out for the next snow season, but for now I have been using a broom which I don't trust too much.

I have been removing the snow off my roof panels with a window washing tool and double long handle extension. The first time i did this I found that the inverter stopped working after i was done - it could no longer hold string voltage (SolarEdge HD). I theorize that cleaning one panel at a time was a bit much for the inverter and optimizers to control.

The company sent me a new inverter which is up and running. Now i shut the inverter off before I remove snow. My interest in snow removal will likely wane as we go forward, but i would think the system should handle snow removal okay.

Looks like a design fault. No such problems here with simple string inverters. Bruce Roe

Solar panels: residential v/s commercial
In this era of commercialization, resources are getting depleted at a fast scale. The need of the hour is not only to use the limited resources wisely but also to switch to alternate sources of energy. Solar power is one such unlimited source of energy which is a key to clean future. Every day, the sun showers sufficient energy that is needed to power everything on earth. Solar energy companies are investing in solar plants and power panels to offer solar kits to its customers in New York, Brooklyn and Long Island.
Solar power is a renewable source of energy which is free from harmful emissions in the air. The entire process of generating energy has a low operation cost as the photovoltaic process which transforms sunlight into electricity requires no additional fuel or resources. Definitely, solar power panels help to reduce the deterioration of the environment and provides us with a clean energy solution to run our daily errands.

Sun power solar panels are the need for both residential and industrial owners as it addresses the same interest for the low operating cost in a sustainable and safe structure. Considering the size of the house v/s the commercial building, the size of the PV panels specified for homes varies from the one installed in a commercial space. So, over 72 cells per panel are installed on a roof of a residential building, whereas the number goes up to 96 cells per panel for a commercial application. Commercial panels are more effective as the surface area of commercial panels is more than that of a residential one. The solar panel installation uses the same bolted racking system for both residential and commercial paneling. As the roof of a commercial building is usually flatter than that of a house, the installation process gets a little easier for the former as the installation system that affixes to ballasts and not penetrates into the roof can be used. Commercial solar panels come in various color options, while for the residential, the option gets a little limited to white or black.

More and more residential and commercial enterprises are making a switch to the environmentally friendly energy source. Despite these minor differences, one thing in common in both is solar panel solution helps the owner to save money and also add to a noble cause of preventing the degradation of the environment.

If you're anywhere near Houghton, or some parts of Keweenaw county you've got a lot of experience with snow.

I am about 80 south of there.

[J.P.M.]

I have 24 PV panels mounted 45 degrees from the ground with a 3' space in the front from the ground. I use a very soft push broom on the end of a extendable painters pole to clean off the snow. My latest panels are e panels which seem to shed everything better than my Canadian Solar panels.I live in the UP of Michigan

Did you get rid of the other callsign? I finally got my 80 and 40 meter dipoles up, we need to try 40 sometime.

Run the lon/lat. Then the vanity will make sense. No my callsign has not changed. W3 is a very specific area. You know how to find me. 40 has been pretty good after dark some evenings. Good sun cycle we are in right now.

The white helped with contrast on the last picture. Sometimes I load up the array at 10GHZ as a phased array,
to try and contact your dish. The white provides a ground plane to help focus the beam. K9MQG since 1958

Where did all that white foam come from? I see that sometimes in Hawaii and here in Panama when kids soap a water fountain in people yards and public parks. Kind of pretty for a day but kills the grass and flowers. Does keep the damn monkeys away as they freak out a bit like the Park Attendant and home owner.
