Q: Can solar panels be installed on historical or protected buildings?
Yes, solar panels can be installed on historical or protected buildings. However, the installation process may require careful planning and consideration to preserve the building's historical integrity. This typically involves working closely with preservation experts, architects, and local authorities to find suitable installation methods that minimize visual impact and potential damage to the structure.
Q: I had an idea for new parabolic solar panels shaped like horseshoes. They can install them outside buildings facing the equator. They could angle them from the ground based on how many degrees latitude the location and rotate them according to seasonal changes. The disadvantage of photovoltaic panels is that they are not all capable of receiving direct sunlight. That is the quintessential reason I believe horseshoe solar panels are more effective than flat rectangular ones. One side could function in the morning; the middle could perform at midday; and the other could operate during the evening. That method seems more sensible than hourly positioning. I'm certain horseshoe panels could save and produce more electricity. A football stadium, shopping mall, or outlet center would be a fantastic place. What do you think?
Sounds like you are thinking which is excellent. Now do a controlled experiment. Using a prototype of your receiver and measure it against existing technology. You could do a computerized mock up.
Q: What is the impact of snow accumulation on solar panels' performance?
Snow accumulation on solar panels can significantly reduce their performance. The layer of snow acts as a barrier, preventing sunlight from reaching the panels and reducing their ability to generate electricity. Additionally, the weight of the snow can cause structural damage to the panels if not properly cleared, potentially leading to long-term issues. Therefore, it is important to remove snow from solar panels to ensure optimal performance and longevity.
Q: If a solar panel (using 36 3x6 solar cells) puts out 60 watts, how many panels would I need (for a house) if I use a max of 2300 kWh in a month? I checked my electric usage for the past 2 years and the kWh is usually lower but I wanted to use the most kWh used (2300) for my question. Thanks!
One key piece of information missing is the average number of peak sun hours per day. This will vary by location. It is latitude, regional weather, and site shading must be considered. Another consideration is the loses. The 60 watt solar panel is a DC voltage. The 2300 kWh is for the AC power consumed. There are loses in the inverter to change the electricity from DC to AC. There are also loses for wire resistance, soiling of the panels, wire resistance, etc. To work out an example of the math, I'll use 5 peak sun hours and a total efficiency of 80%. The math can be worked out as a single formula but I'll break it into steps for you. (2300 kwh/month)(month/30.4 days) = 75.65 kWh/day (60 W)(5 psh)(80%) = 240 Wh/day = 0.24 kWh/day/panel # of panels needed = Energy use / Energy generated (75.65 kWh/day) / (0.24 kWh/day/panel) = 36 panels.
Q: I don't have a regulator connected as they are a little expensive for a pensioner, If I join the panels into line to the battery bank from the roof should that be OK.?
Two things on a regulator: a) It will optimize the charge to the batteries - and thereby distribute the most possible power to your active circuits during the day. b) It will prevent the power from the panels from boiling (no kidding) the batteries - no small thing as they are the second largest investment you have after the panels themselves. This is much more critical if you have sealed or Zero-Maintenance batteries. I strongly suggest that you get a regulator as it will significantly lengthen battery life. Follow the directions on the regulator for optimum input voltage and it will let you know whether all the panels should be in series, parallel or series/parallel. But cutting to the chase, you can certainly gang up panels as needed.
Q: Can solar panels be integrated into buildings?
Yes, solar panels can be integrated into buildings through various methods such as rooftop installations, facade-integrated systems, and solar windows. These integrated solar panels not only generate clean energy but also blend seamlessly with the building's architecture, making them a popular choice for sustainable and aesthetically pleasing designs.
Q: Do solar panels require permits for installation?
Yes, in most cases, solar panels require permits for installation. The specific requirements and regulations vary depending on the location, but obtaining permits ensures that the installation meets safety standards and compliance regulations set by local authorities.
Q: Can solar panels be used to power a school?
Yes, solar panels can definitely be used to power a school. Solar panels are a sustainable and renewable source of energy that can generate electricity by harnessing the sun's energy. By installing solar panels on the roofs or grounds of a school, it is possible to generate enough electricity to power various electrical systems within the school, including lighting, heating, cooling, and other appliances. This can not only help reduce the school's reliance on non-renewable energy sources but also lead to significant cost savings in the long run.
Q: Is this a good kit for building a solar panel?
Only okorder /
Q: There is a charge controller that has what i believe to be only port for a solar/ wind turbine control panel and i don't know if it has more than port for panels. So would i be abed to link 2 panels to port or do you think the controller has more than portBTW it is for marine use.
Solar panels are like batteries, hook them up in series and you increased the voltage, hook them up in parallel and you increased the current. You should review your first year physics notes on the matter.
