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:Cost of Solar Panels for basement?
Only after you give an estimate of the power consumption you will have in the basement. Obviously you do not have a clue about solar panels or their usage. Suggest you find a book and start reading.
Q:are solar panels sufficient for electric heating?
Are you thinking of installing electric solar panels or thermal solar panels or both? It would be better to install electric solar panels for electric heating. You can run 7 heaters as long as you do the calculations for the number of panels need for the daylight hours, and the required battery bank to supply the required power.
Q:What is the best solar panel?
your initial outlay for a solar panel is very large in terms of output.......somewhere around $4 a watt......ie you want a panel that will run a 00 watt lightbulb? $400.00 please. enough panels to collect enough energy to recharge a battery bank to run the house overnight? well, I've been doing a lot of research for my condo project in St Thomas and it comes out to 0-20,000 US $ for a bedroom apartment. Now, after about ten years you have made your investemnt back.... and there are a lot of government rebate programs that lower the cost.. what I have found is solar is nice, but depending on how far north you live you may only have 4 usable hours of light a day. you may very well be better with a wind generator.wind blows all the time after all...Bergy and SouthWest Windpower make two good small home units...start there
Q:Solar Power Question?

Q:Any drawbacks for solar panels?
I guess the main thing is to look out for the warranty like where the warranty is claimed and the process of claim, how efficient the inverter of the system is and also make sure you are getting value for your money.
Q:Need Large solar panels. ?
I think you may be surprised how much energy a little cafe like that uses. Since the air conditioning, refrigerators, and other appliances are going nonstop, I'd expect the energy usage to be several times that of a normal house. If you have access to the electric bills of the cafe while it was in operation, look up the kWh's used per month. For scale, I will say that our house uses 500 kWh per month, and needs 3 kW of panels to keep up with that. Scale up to match the restaurant, as a ballpark estimate. If you don't have access to the electric bills, then go visit a similar cafe in town, or a nearby town, and ask them how much their electric bill is. If the ballpark estimate still looks doable to you, then contact a professional solar installer to get an accurate, no-obligation estimate. Most likely, the cafe will use gas heat for cooking. But if not, electricity from solar panels is probably the most inefficient way to cook. Consider having solar ovens for most of the cooking, if you have land, with gas as a backup on cloudy days.
Q:Solar Panels, anyone?
You can attempt to install your own solar panels...just do the homework first! I suggest looking at ways to decrease your overall energy consumption first even if installing solar panels. Doing this will save on the amount of panels you need. Have included a reference that may be of use to you.
Q:2 Questions on Solar Panels?
Solar panels are available in a wide variety of power ratings.  Energy is the sum of power over time, so how much energy a panel produces depends on the intensity of the light hitting it and how long it's applied. I understand that current single-crystal silicon PV panels are warranted to produce ~85% of their rated output for 25 years.  Most will do better, and will produce useful output for perhaps 50 years or more.
Q:Designing 3d Solar Panels?
I don't know anything about the 3D thing. You cannot get more energy out, than goes in. Energy will only hit the mirrors. With some loss of efficiency they would reflect a focused beam into the chamber, where with some more losses would reflect it to the solar panels. It would be more efficient just to expose all the panels to sunlight.
Q:Solar panel questions...?
. Do they scratch easily? No How do I remove snow from them without scratching them? Just wipe the snow off 2. What does the upkeep of many solar panels consist of? Clean them with tap water and paper towels once a month. 3. Are all solar panels made from the same material, regardless of size? Basically the same.
