- 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
- It doesn't make sense to me. I am at latitude 37.7,and my panels face south at about 38 degrees. Yours should be pointed north as you suggest. Being so close to the equator, and in the absence of any better information, an angle of 2 degrees would be appropriate. However, choosing the best angle will greatly to your overall efficiency, so I would try to find a more credible source, How about the folks from whom you buy the panels. They would know precisely. By the way, if you haven't installed the system yet you might consider going to a high voltage system to cut known line losses in the conductors between the panes and the inverter, I did that plus increasing the conductor size over that recommended by the manufacturer. I gained about two percent in efficiency
- Q: how much energy or electricity a solar panel produces?
- First, okorder /... Second, as a general rule of thumb, you can generate at most 00 watts of power (.Kwh) per 2 square feet of roof space. I have had to revise my own estimates after building a solar array in my yard using high grade solar panels. Solar panels do not put out their peak rating all the time. NOTE: I am not paid nor given any compensation by solar interests.
- Q: Hi, I have in my sailboat 2 2 V batteries. I would like to buy solar panel(s) in order to recharge them. As i am in mexico and there is always high sun . i think it is a good idea.Usage of the batteries is very light . I have found 5-2V pannels with 80mA that fit in the sailboat. I want to know if and how i can have like 5 to 0 of them set together to charge the batteries and what other material would i need.also, i would like to know what happend if the pannels only send on 5V in a 2 V battery? Is it still charging but on 40 % of the capacity a 2 v pannel would charge or its just not doing nothing ?
- Taken at face value, it would take about 55 hours to re-charge a dead flat battery. However, you don't get 24hrs/day sunlight. Even worse, the output from a panel is only maximum when the sun is at 90 degrees to the surface. Let's assume you can find some way to track the sun. No battery should be allowed to discharge below about 50% so we can halve the recharge time. I would say about 4 days.
- Q: What is the impact of snow accumulation on solar panels' performance?
- Snow accumulation on solar panels can have a significant impact on their performance. When snow covers the panels, it blocks sunlight from reaching the photovoltaic cells, reducing their ability to generate electricity. Additionally, the weight of the snow can put stress on the panels and potentially damage them. However, some modern solar panels are designed with anti-reflective coatings and tilted surfaces to minimize snow accumulation and aid in self-cleaning. In regions with heavy snowfall, regular cleaning or snow removal may be necessary to maintain optimal solar panel performance.
- Q: if u buy solar panels and never take em out of the box for like thirty years will they still work good thirty years after you bought them
- They should do fine.
- Q: What is the environmental impact of solar panels?
- Solar panels have a positive environmental impact as they generate clean and renewable energy. They reduce greenhouse gas emissions, air pollution, and dependence on fossil fuels, mitigating climate change and improving air quality. However, their production and disposal do have some environmental impact, including resource extraction and waste management, but these impacts are significantly lower compared to conventional energy sources.
- Q: Can solar panels be used to power a concert venue?
- Yes, solar panels can be used to power a concert venue. By installing a sufficient number of solar panels, a concert venue can generate enough electricity to meet its power requirements, including stage lighting, sound systems, and other electrical equipment needed for the event. Additionally, solar panels can help reduce the venue's carbon footprint and dependence on traditional energy sources, making it a more sustainable and environmentally friendly choice.
- Q: Can solar panels be used in areas with high levels of saltwater?
- Yes, solar panels can be used in areas with high levels of saltwater. However, it is important to choose solar panels that are specifically designed for such conditions and have corrosion-resistant materials. Additionally, regular maintenance and cleaning of the panels may be required to prevent damage from salt build-up.
- Q: I am designing a solar panel but i need to have maximum power output.How can i optimize the equation for power Total power=voltage * current to get maximum power.
- first place the panel so it is at right angles to the solar rays. Make sure none of the panel has any shade whatsoever. For best results use motor drives to keep it in that position as the sun moves across the sky. For overall maximum versus time, you need to be near the equator. Solar cells have a high internal resistance, so for maximum power transfer, you need a load of that same resistance. A good charge controller will use DC-DC converters to provide that load. .
- Q: Hoping to find instruction, materials list and hardware needed to construct solar panels myself, how many and make it happen instead of talking about it
- Silica based solar cells are not the kind of thing you whomp up in you basement. Here are a couple ideas for solar systems you can build and install yourself. Take a 4 x 8 sheet of /2 inch plywood. Frame sides with 2 x 4's. Screw tin cans in a staggered row (checker board) pattern inside frame. The more cans the more heat you get so place them nearly touching. Paint cans and entire assembly flat black. Cover top with glass, plexiglass (best) or heavy mill clear plastic (cheapest)Place on roof. Drill 3-4 inch holes in opposing sides. Run pipe or tubing into house. Attach to small low speed fan. The black paint will absorb sunlight and heat. The air moving through box will carry heat into house. It's a cheap efficient way to help heat your home. You can vary size and shape of box to fit your roof. If you use more than one box, hook them up in series. More boxes mean more surface area means more heat. To heat water. Take a steel tank. A car gas tank works well. It is galvanized so it won't rust, is cheap, and easily available at any auto salvage yard. But you will have to flush in throughly to remove gasoline odor. A steel 55 gallon drum is easier to work with but may cost more. Paint exterior of tank flat black. Weld/glue/clamp water pipes to tank. Place on ground in area that gets lots of sunlight. Attach water supply to tank and route discharge pipe to house or appliance. Black painted steel absorbs heat from sun light and heats water. In spring and fall you get warm to hot water. In summer you get scalding hot water and in winter you get cold to luke warm water. Both of these solar powered systems are seasonal and their output varies according to location and climate, but they are very inexpensive and easy to build and provide FREE heat and/or hot water for many years with little or no maintainence.
