- Q: If we invest billions in green energy and put up thousands of square miles of black panels that give off radiant heat couldn't that significantly cause more warming, not to mention the energy required to even make them?
- Essentially, solar panels are 'warming neutral'. They absorb energy that would otherwise have heated whatever was behind them, thus have a local cooling effect. This is balanced by the generation of heat when the electricity is used to power, say, a hoover, TV, computer etc, also from 'transmission losses' through the national grid network. Good answers from Claire and Linlyons, bizarre answer from Jim! Tomcat may have a point though...
- Q: Can solar panels be installed on a landfill or waste management site?
- Yes, solar panels can be installed on a landfill or waste management site. In fact, these sites can provide suitable locations for solar panel installations due to their large open spaces and minimal shading. Additionally, repurposing landfill sites for solar energy generation helps to utilize otherwise unused land, reduces the environmental impact of waste management, and promotes the production of clean and renewable energy.
- Q: How do solar panels affect the property's LEED certification?
- Solar panels can have a positive impact on a property's LEED certification as they contribute towards earning points in several categories such as Energy and Atmosphere, Sustainable Sites, and Innovation in Design. By generating renewable energy and reducing the property's carbon footprint, solar panels can help achieve higher energy efficiency, promote sustainable land use, and demonstrate innovative practices, ultimately boosting the property's LEED certification level.
- Q: Can solar panels be installed on churches or religious institutions?
- Yes, solar panels can definitely be installed on churches or religious institutions. In fact, many religious organizations have embraced solar energy as a way to reduce their carbon footprint and promote sustainable practices. Installing solar panels on churches not only helps them save on electricity costs but also serves as a visible commitment to environmental stewardship and can inspire the community to adopt clean energy solutions.
- Q: How much space is needed to install solar panels?
- The amount of space needed to install solar panels varies depending on the size and quantity of panels being installed. On average, a single solar panel requires about 15-20 square feet of space. However, it's important to consider factors like panel orientation, shading, and energy requirements to determine the exact space needed for an installation.
- Q: What specification of solar panel would I need to power a laptop every day? I would need to use it for about 0 hours or so every day. I don't know anything about solar panels, but I am seriously thinking of getting one now and don't know who to ask.
- I okorder / says they have DC to DC solutions from 2 V for most laptops.
- Q: I found portable solar panels used for boats etc. and was wondering how I could effectly use them for my home instead. If you have used them in the past, please tell how they worked (good or bad).
- from what i have seen and heard the portable panels you are talking about are not big enough for home use unless you create a specific outlet to use them on such as one for cellphone charger or other small use items. Just my semi-educated guess.
- Q: I was just wondering what the minimum and maximm charging voltage and ampere is for li ion batteries. If i connect a solar panel, which only gets enough sunshine to generate voltage, will that still charge the battery, or would i have to series connect solar panels until they together reach 3,7volt?
- One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .
- Q: So I'm trying to figure out what to ask for my birthday because its one of the few times I can get stuff for no reason, like stuff I don't normally go to the store to buy. (i dont go to the store to get much at all anyway).Anyway, I'm interested in solar panels and led and electronics and i was wondering if there is anything not over expensive that would be cool. Some things I'm interested in:solar, wind, water energyGadgets (multitools, swiss army knives)Vibram fivefingersdrawingmaking stuff (duct tape wallets, stuff out of altoids containers)basically technology and outdoors-gear stuffoh and im 6 turnin 7 male.
- solar panel is expensive, but small solar panel is not expensive, for example, 5w solar panel, solar light also not expensive led light also not expensive. i am not sure about other stuff that you said
- Q: okay so my teacher is trying to install a solar panel but we have a problem we don't know where to ground it because it will be a movil house. guys do you have any ideas?
- A Mobile home will have its frame grounded when connected to a standard electrical 'plug-in', if it was built to current Codes. If you plan to use that panel as the entire electrical system you'll need to ground the frame. Vehicle systems, (frame grounded), are 2 Volt for a reason. It would be unwise to use a separately derived 20V. system in that mobile home if that frame's not grounded. (That first step out on to the ground could be a 'lulu'.)
