    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.
    Mod Note: You may post about using solar pv products but you are not allowed to attached website links. I deleted your second post. Do that again and you will be banned.

    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.

    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.

    Here is my QTH so you can aim your Dish at me:

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.

    'devastating' is a little over-exaggerating I think. On cloudy days and on snowing days production is down, that is why most systems in my area have battery-banks.

    I have found that Rain-X helps considerably.

    It may also interfere considerably with the ARC coating on your panels and also conveniently void your panel warranty if the panel mfg. finds out about it.

    And besides, panel mfgs., at least some, and as Russ was told by a panel mgg. or two about four or so years ago, Rainex might damage the ARC coating or interfer with its effectiveness or purpose, and voiding the warranty.

    Anyone else who was around back then have any recollection of that ?
