SITE SELECTION

In most applications, the PV modules should be installed in location where there is no shading throughout the year. In the Northern Hemisphere, The PV modules should typically face south, and in the Southern Hemisphere, the PV modules should typically face north. Please make sure that there are no obstruction in the surroundings of the site of installation. Take proper steps in order to maintain reliability and safety, in case the PV modules are used in areas such as: Heavy snow areas/Extremely code areas/ Strong wind areas/Installation over, or near, water/ Areas where installations are prone to salt water damage (*)/Small islands or desert areas.(*)

If you are planning to use the PV modules where the salt water damage may be possible consult with CNBM local agent first to determine an appropriate installation method, or to determine whether the installation is possible?

 

Q:I'm thinking of these solar panels that people have on their rooftops in domestic properties. I suppose I mean after how long do you break even with respect to just carrying on without them and getting you electricity from the utilities companies? Or answer in any way you think is pertinent. The more info the better.
Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q:I was thinking of having some installed on our rooftop and was wondering if it would be worth the cost? The house is located in Sac, Cali. The panels would face the sun 2 months out of the year and in the summer roughly 4 hours of straight sun.

Q:I need a new roof soon and I was wondering what the difference in cost would be from a standard shingle roof to a roof including solar panels. Does anyone know the cost difference?
The solar panels are very expensive to provide much power. If u go that way do not skimp on the support as a high wind will blow them away. In Ecuador I put in a remote site for communications. It was working good when a Strong wind blew $0.000 worth of solar panels all over the jungle.
Q:By best I mean safest places. If I were to install them on my roof am I risking due to damage from weathering? Such as rain or snow. I don't get very high winds around here, nor any natural disasters such as hurricanes or tornadoes. Does anyone have solar panels that have been durable for a long time? Is it worth the investment?
The best place is where they get the most sunshine. Naturally they will be exposed to rain and snow.
Q:What, if any, improvement in efficiency per square foot or meter is realized by a solar panel in space vs. being mounted on the ground where the light is attenuated by the atmosphere?In passing, I found a site that gives an output of .89 watts / 4 in. sq for a particular home-mounted panel.
I'm not sure on the exact numbers of solar panel efficiency, however i do know that at the radius of the Earth we should be receiving about 000W of power per square meter. This value is lessened by the atmosphere to a value closer to 600W per square meter on the Earth's surface. (on a really hot day) That's a 40% drop in power due to the atmosphere. I'm assuming that the solar panels being in space don't affect it's efficiency (as in mechanically). So its power generation should increase by about 40% when in space compared with a ground based panel of the same design. Hope this helps, Sorry it's kinda sketchy info...
Q:Do solar panels produce noise?
No, solar panels do not produce noise as they generate electricity from sunlight without any moving parts.
Q:Can solar panels be used for charging electric vehicles?
Yes, solar panels can be used for charging electric vehicles. Solar panels convert sunlight into electricity, which can be used to charge the batteries of electric vehicles through a charging station or directly through a solar-powered carport. This provides a sustainable and renewable source of energy for electric vehicle charging.
Q:Can I make a solar panel at home?How to make it?
It's not necessary. The time, materials, energy, and money you have to put out might not be worth it. Being this is your first unit, there are cheap enough panels; you should shop around. OKorder alone with an array of selections and there is Home Depot and others. When solar panels not hooked up correctly or you don't have the right equipment you can cause the batteries to explode. Do your research there's plenty on Youtube. I'd read the answers here but you really need to do some homework elsewhere. It is that serious that I wouldn't give any advise on the how to.
Q:i want to build a stationary model of a solar panel and i dont know if it is going to be too simple or not i also want ideas to make it betterplease criticism is allowedmy idea was to make a case, just like a real solar panel, and take plexiglass to make it. i want to add some models of photovoltaic cells that look like they are in a solar panel . i want to add the fake shoulderings as well . i want to make the case openable by hinges.i would like some of your thoughts and ideas to help me .thx
