- Q:I need to know how Solar panels work please help me!! Also, if you know any other additional important information about Solar Energy in General please tell me, Thanks.
- sunlight is collected by cells in a panel which is transefered to enrygy
- Q:Can solar panels be used in areas with high levels of heatwaves?
- Yes, solar panels can be used in areas with high levels of heatwaves. In fact, solar panels are designed to convert sunlight into electricity, and they perform better in areas with higher levels of sunlight and heat. However, it is important to consider the impact of excessive heat on the efficiency and lifespan of solar panels. Proper installation, maintenance, and cooling measures may be required to ensure optimal performance in areas with extreme heat conditions.
- Q:Do higher watt solar panels last longer, efficiency-wise? 3 installers gave me quotes with 3 different sunpower panels. The 225, 25, 20 watt panels. Whats the con and pro's of the different wattages?
- You should get the highest efficiency at the lowest price. Typically, the Sunpower brand panels have the industry best 23% efficiency depending on the model. You have to look at the specification very closely and if you don't see it, ask. There are two types of solar cells Polycrystalline and Monocrystalline. Polycrystalline cells are inferior to Monocrystalline. You will also see that different kinds of panels have different output voltages.Since you will be wiring your panels together and connecting them to either a power inverter or a charge controller (if you have battery backup), you need to make sure the panels and controller work together for maximum efficiency. Be very careful when engaging an installer especially when they are trying to sell you the equipment too. Mostly, these are not engineers and you will end up with whatever they have in stock without regard for the most optimal design.
- Q:Are solar panels suitable for all types of roofs?
- Solar panels are suitable for most types of roofs, including flat, sloped, and metal roofs. However, the suitability may vary depending on factors such as roof orientation, shading, and structural integrity. It is recommended to consult with a solar installation professional to determine the best options for a specific roof type.
- Q:Can solar panels be used for charging batteries?
- Yes, solar panels can be used for charging batteries. Solar panels convert sunlight into electricity, which can be stored in batteries for later use. This makes solar panels an effective and sustainable solution for charging batteries, especially in remote areas or during power outages.
- Q:The voltage and power problems of solar panels
- Because the MPPT controller has a wider input voltage range, it can also convert multiple voltages into current charge and better protect the battery.
- Q:Can solar panels generate electricity at night?
- No, solar panels cannot generate electricity at night because they rely on sunlight to produce power.
- Q:I want to replace my electricity with solar and wind. I live just right outside the city, the roof about 000 square feet. How many windmills/solar panels would it take to get me off the power grid?
- I live in the Southwest where the sun shines almost every day. I got a quote for Solar system to produce about enough to cover my annual usage. My annual average electrical usage costs about $2300, or about $90/MO. The system costs around $30,000 but I can get rebates and some of your tax dollars in subsidies to bring my cost down to under $20,000. I can borrow $20,000 for 3 years at 7% and pay $95/MO, so in 3 years I will have the system paid for. As you can see, I don't start Saving any money for a long time. Maybe the rates will go up in later years which will help, but My friends that have solar systems tell me things like controllers go bad over time and they cost like $3000. Will it ever pay for itself? Maybe. Please note. This still does not get me off the grid. This system will not support things like an electric stove, air conditioning, Pool pump running, etc. so I still need the grid for when these operate and my usage peaks. If I installed a system that would totally support everything 24/7 the cost would be astronomical. If you live in the east, midwest, or NW where you have cloudy days, your economic calculations will be much less favorable I would think, unless your power costs are much higher than mine..
- Q:There are places in the US where it is sunny almost all the time, like the southwest. But if we covered an area of the Sahara with solar panels, the sun exposure with the area would generate enough energy for the whole US at least. Plus, I would imagine it would be a great source of income for those countries.Why isn't this a topic under discussion or even mentioned between countries' governments/in Congress/in politicians' viewpoints?
- It takes companies or citizens to desire to switch their power source. Yes some areas build solar or wind abilities to create power. Its not super cost effective but getting there. Its new technology, that use to be super expensive to make panels, and now is more affordable. In todays world economy, even though it would help down the road, noone has the money to redo their power source right now, its cheaper to just pay the company providing power. All new things take time to be implimented, studied, planned, and permitted. There will be a slow increased usage, but its not like tomarrow everyone will ask for solar power and companies invest to make it available, just cant happen that way. For your Sahara synario, each country can deal with its own power needs, to bring the power from the Sahara to another country is not doable, each desert area could power its nearby areas, when the need and desire arises. In most continents of the world, individual countries are more concerned with basics, clean water and food, and most dont do a good job at providing that, solar power to poor nations, although its a good thought, just isnt a concern now, its clean water and food, medicine is more important. The big picture warrants more diverse ways to get power, but the world is not as one, the countries do not discuss their needs with other countries. Some countries come to the rescue of others on their own if allowed to. Someday, hopefully the world will be more eco friendly, and peole wont starve to death daily
- Q:For my exam in science we are required to make a power point explaining why it would be good for our school to switch to solar. our complete handout given to us by our teacher is as follows:Power Point to include:. What you propose for alternative energy usea. Any thoughts on energy conservation...2. Why this is a good idea3. What information you would give the solar company (area of roof space your group determined to be useable for solar)In PowerPoint - include your quot;scriptof what you would be saying when the slide is up in the Notes section below the slideANY HELP WOULD BE GREATLY APPRICIATED!!THANK YOU SO SO MUCH,QH
