- 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: A solar panel facing the sun at noon in mid-summer receives more intensity of the light than when it is at horizontal. However, it can receives more total solar energy when it is at horizontal than when it is tilted during a long summer day. Regradless if it is shaded by building or trees. why is that so?
- That okorder /... it shows a graph and explains it better.
- Q: Do solar panels require a specific orientation or angle for optimal performance?
- Yes, solar panels do require a specific orientation and angle for optimal performance. Generally, it is recommended to install solar panels facing south and at an angle equal to the latitude of the installation location. This allows the panels to receive maximum sunlight throughout the day, maximizing their energy production. However, panels can still generate electricity when facing other directions or at different angles, although their efficiency may be slightly reduced.
- Q: Am using 800watts sukam inverter and have 55watts panel. What controller can i use to connect my solar system to have a max power . Already i have 200 Amp/hr battery
- You need a charger Controller but 55 watt panel is not a whole lot of power. So yes you can buy a very good one but it will cost a lot more. For a 55 watt panel you only need a 4 to 7 amp controller. But why not buy a 0 amp so you can add a second solar panel etc... A PWM (Pulse Width Modulated) is the cheapest and most robust type MPPT (Maximum Power Point Tracking) These controllers actually detect the optimum operating voltage and amperage of the solar array and match that with the battery bank. The result is additional 5-30% more power out of your array versus a PWM controller So unless you have a system over 200 watt the PWM works very good I have two of the PWM myself
- Q: Can solar panels be installed on wearable devices?
- Yes, solar panels can be installed on wearable devices. However, due to the limited surface area available on wearables, the amount of energy generated may be relatively low compared to larger solar installations. Additionally, the efficiency of such panels may vary based on the device's orientation to the sun. Nonetheless, incorporating solar panels on wearables can contribute to extending battery life and enhancing their overall sustainability.
- Q: Can solar panels be used to power a greenhouse?
- Yes, solar panels can be used to power a greenhouse. Solar panels produce electricity by converting sunlight into energy, which can then be used to power various devices and systems, including heating, cooling, lighting, and ventilation in a greenhouse. This renewable energy source helps reduce reliance on traditional power sources and can provide a sustainable and cost-effective solution for powering a greenhouse.
- Q: Photo-Voltaic solar panels are very expensive. Most of a home's energy needs are for heating water, heating and air-conditioning. All of these can be met with thermal solar collectors which are much less expensive. The thermal solar panels would heat water stored in a hot water tank which then can be used as hot water, to heat the home, or as the heat source to a Lithium Bromide Absorption chiller to air-condition a home. With the base line needs met without expensive panels and without inefficient energy conversions, only a small Photo-Voltaic array would be needed for the remaining power needs and since those needs are variable, there would still be power to sell to the grid.
- you completely nailed it!! speaking about large buildings, it would benefit one to do a little more research. my company just installed a 640 collecter system on a million sq foot building. it consists of a absorption chiller (which uses no coolant, just water a silica gel beds, runs of the power of its controller, thats it) 27,000 gallon tank. chiller feeds 2 rotation units and 2 large office spaces for heat and cool. payback expected at less than 5 years. we will expand this system another 200 collectors. residential installs, if tax credits used, achieve 5-7 year payback pending domestic hot water only or dhw and space heating. thermal collectors actually produce more energy than pv panels do, therefore more bang for your buck, also as i hope you all know, pv has around 25% eff, thermal has 95%. also to say the tech part is gone, we use flowmeters that calculate carbon offsets, energy saved, money saved etc...all located in a wireless monitor for the consumer to enjoy.
- Q: Can solar panels be installed on a high-rise building?
- Yes, solar panels can be installed on a high-rise building. In fact, high-rise buildings offer great potential for solar panel installations due to their large surface area and access to sunlight. However, it is important to consider factors like structural integrity, shading, and local regulations while designing and installing solar panels on high-rise buildings.
- Q: Do solar panels require building permits?
- Yes, solar panels typically require building permits. The requirements for obtaining a building permit may vary based on location and jurisdiction. It is essential to check local regulations and obtain the necessary permits before installing solar panels.
- Q: my dad wants to run all his lights in his shop on solar panels, he has 9 600 watt hps lights. how many solar panels would it take to pull this off
- It depends on how many watts of electricity you wants..
