Q: Hi, i want to please a solar panel in Lima Peru, my Latitude is -2 and longitude -77. I understand that since i am in the southern hemisphere, my panel should be pointing north. However, i am using a program called pvdesigner, and according to this, y should face my panel with and azimuth of 00degrees (0 = south) and a tilt of 60degrees. Does this make any sense?thanks: Typically, solar panels are installed facing the same as your latitude = 2 degrees to the North measured from horizontal. 60 degrees from vertical = 30 degrees from horzontal will give almost as much power in June as in December = beginning of Summer. You can face your panels straight up = zero tilt from vertical = better for December/ not so good in June. Usually, the same tilt as your North facing roof is best as it simplifies installation and reduces wind loading. Shade from trees etc will much reduce the power you get. Neil

Q: Solar panels are costly.Do you know any inexpensive way?So that i can make one of my own.: Solar things are always costly... You can use concave mirrors and concentrate the heat and heat what and then steam ll be formed and then steam directed to turbines, there you go generating electricity with out solar panels...

Q: I was hearing that we need silver as a medal for the creation of solar panels, is this true? How much silver would be needed to make one solar panel? (if this is true): Some research has shown that small amounts of silver can improve the efficiency of solar panels. But this appears to be in the research stage and applies to the the thin film solar cells. Some solar panels makes use silver as the wiring in kind of a screen printing process, but you don't need to use silver, you can use copper or aluminum using different techniques instead. Generally the metal used is in small amounts and not a majority of the cost of the solar panel.

Q: I was looking at thin flexible solar panels as solar panels 500w a option to upgrade a 20w solar panel I have permanently mounted to the roof of a home made camper van.Why I was thinking flexible is at just 2mm thin they can be glued down and being flexible they will follow the contour of the rounded shape of the roof of my camper (boxy standard solar panel spoils the lines a little)Another reason is no glass to brake when traveling on dirt tracks(though I am surprised mine hasn't broken yet after thousands of km on corrugated dirt roads). Finally there is a weight saving at only /3 the weight or less then a standard glass panel.There are different grades of flex PV some of the more expensive ones are very flexible with extremely thin backing at around .5mm The ones I was looking at are cheaper and at around 2mm with a thin flexible aluminum backing.$250 is about the going rate for 20w OKorder job. Below is a pic of a smaller one 60w or so.Has anyone had any experience with them?: Guide okorder /

Q: How do solar panels affect roof ventilation?: Solar panels can have both positive and negative effects on roof ventilation. On one hand, solar panels can provide shade to the roof, reducing heat gain and potentially improving the overall ventilation of the roof space. On the other hand, solar panels can obstruct airflow and create a barrier that hinders natural ventilation. Proper installation and design considerations are crucial to ensure that solar panels do not negatively impact roof ventilation.

Q: so i told my dad to buy solar panels and he wants to see how much money u can save we pay $00 and i dont want quot;You don't need solar panelshow much would my fmaily save?: I would suggest getting more info about solar panels, here's the stuff that could be helpful to you renewableenergyarticles.blogspot....

Q: Dont/Cant work alone?when you buya asolar panel you mUST GET bATTERIES, voltage regulators and many else stuff?cant they just work directly? or can i use normal batteres like Car batteries?The one who Really knows 0 pts. thanks: It is a system, you can get a small scale panel that can do things like charge cel phones and ipods. The type of system I have installed on my home needs a converter that turns the dc current that is produced by the panels into ac current to run in my home. I don't have a battery system because I'm not off the grid. When I'm generating more electricity than I am using I sell it back to my utility and at night when I'm not gernerating any electricity I buy it back again. Basically my meter runs backwards durning the day and frontwards during the night.

Q: Have a 20V 40W solar panel and it is attach to two backup batteries. Just want to know know how many watt of inverter do I need?: 500 Watt Solar Panel

Q: Can solar panels be used in areas with high levels of saltwater exposure?: Yes, solar panels can be used in areas with high levels of saltwater exposure. However, it is important to take certain precautions to prevent corrosion and maximize their performance. This can be achieved by using materials that are resistant to saltwater corrosion, such as stainless steel or aluminum frames, and encapsulating the solar cells with durable and protective coatings. Regular maintenance and cleaning can also help ensure the longevity and efficiency of solar panels in such environments.
