- Q: Hey i am going to build a scale model house and demonstrate how you would use solar panels to provide energy. I am thinking of buying some kit solar panels and wiring up some lights to show how they power the home. Also i might hook up a battery in the house to show how you can store the energy. I might also have a large battery hooked up outside the house to represent a power plant that could provide emergency power. Any ideas or comments would be great. Thanks

- Q: Can solar panels be installed on a metal roof?
- Yes, solar panels can be installed on a metal roof. In fact, metal roofs are often considered ideal for solar panel installations due to their durability, longevity, and compatibility with the mounting systems. Metal roofs provide a stable and secure foundation for solar panels, ensuring optimal performance and longevity of the system.
- Q: Got a quote for about $K today for solar panels to save me about $00 a month on my electric bill. I was just wondering if anyone had successfully bought and installed their own and how it worked for you?
- i have always been interested in it but the storage (batteries) and power grid tie in (to get paid for excess) technicalities made me shy away. since your getting it installed im sure labor is a huge part of that -OKorder has tons of the equipment. I think wind may be a good home renewable source depending on where you live (cheaper than solar if you got the wind and space) I would doubly check any goverment offerings - I know they used to and maybe still do offer sizable credits if you are within the bureacratic standards so make sure the installers work with you on that. good luck -its new - and going to be a hassle to get right but the world needs more like you. willing to pay more now for a better tommorow (and not just $ wise) you should come out ahead as interest rates and market provides little value on that cash and saving any equipment falure you sound good. does the price include the batteries for all your produce kwh's? panels and labor aside batteries are the next big one
- Q: Hi All,I need some resources for a research project i'm doing on Solar Panels/Cells.So do you know of any good books or online materials that basically covers how solar cellwork from level 0 to calculating the energy output based on intensity of the light and the area of the panel. Book titles will be preferable but i'd like to build a strong base before tackling long and complicated formula(s)... so any suggestions? Your help will be appreciated :)THANKS IN ADVANCE!!
- The two wiki links below provide basic explanations that are good starters. They also lead to other information. You do not mention much about the actual project, so I can only guess what level to pitch the answer. In practical situations you will not be able to work out Solar panel performance by a formula, but by looking up the manufacturer's specification (data sheet). From that you have the power in watts that can be drawn from the panel for standard sun which is taken as 000W/m^2 at a standard temperature, usually 25C. Derate the panel for the temperature when it operates in the sun (50-60C).
- Q: Can solar panels be connected directly to motor?
- Power supply must be a number of individual battery strings, connected in parallel and tightly packaged into components.
- Q: How do solar panels affect roof ventilation?
- Solar panels can potentially affect roof ventilation by creating shade and reducing airflow, which can result in higher temperatures and reduced effectiveness of the ventilation system. However, this impact can be minimized by using solar panel mounting systems that allow for proper airflow and by ensuring adequate spacing between the panels and the roof surface.
- Q: Can solar panels be installed on historic buildings?
- Yes, solar panels can be installed on historic buildings. However, the installation process may require careful planning and consideration to ensure that the panels are discreetly integrated with the building's architecture and do not compromise its historical value. In some cases, solar panels may need to be installed in less visible areas or designed to resemble traditional building materials. Additionally, it is important to consult with preservation experts and local authorities to ensure compliance with any regulations or guidelines specific to historic buildings.
- Q: Around this time here in Georgia we will begin to get some big storms with high winds. I have a solar panel on a mount that isn't all that sturdy and could be knocked over with any winds pretty much above 5mph. I can't put anything in the ground to do this. I used to have it mounted to the roof of a playground for the most sunlight, but because of the angle of the sun and the tree leaves, I have to have it on a quot;portablemount so I can move it throughout the day, and I can tell you one thing is certain, and that's that it isn't the most sturdy thing ever. I'll have it a little better next weekend but it'll still be able to easily blow in the wind. Should I just hang the panel along the wall during a storm then reconnect it to its base once it's over?I'm pretty good with wood, so any wood creations to help out with the thing would greatly help. Just please keep it on a low budget.
- You have to make the decision weather you want it portable or stationary. If you want stationary I would make some good brackets for them / search for cheap ones on OKorder. I'd have to see them to be able to offer any better suggestions. It's always hard to decide so you'll have to take notes and do research.
- Q: I am looking at a need of roughly 30w/hour need per 24 hour period. I have spent several hours now looking for information online and have found plenty of info regarding the panels themselves, but information regarding the batteries backups have been slim. I understand that there is a 5-7 hour peak time to collect the energy. I am looking for information regarding the batteries themselves. How do the batteries work, what size batteries should I look for, and what is the life expectency for the batteries? Any website links would also be appreciated!
- First, you didn't say the voltage. Second, 30 W/hour per day. Third, battery backup capacity in Ah = Ampere hour. For 2 Volt DC here's the calculations : 30 w/hour means = 0.83 or rounded Ampere hour. You know peak time 5-7 hour (let say 6 hour)charging time (collect the sun energy). Ampere hour per day (24 hour), with 20 Ah Battery backup is OK. And the Solar Panel is 3 Ampere charging capacity minimal = 3 Amp x 6 hour = 8 Amp hour.
- Q: Can solar panels be used in areas with limited space?
- Yes, solar panels can be used in areas with limited space. There are various options available, such as rooftop solar panels, solar canopies, or even solar panels integrated into building materials. These solutions are designed to maximize the utilization of limited space while still harnessing solar energy efficiently.
