Q: So, I've seen cheap solar panel kits for sale from Harbor Freight, and regardless of whether or not I were to buy a set from them or someone else, I was wondering what the process of implementing a small-scale solar system into your household electrical system would be.I've read articles that started out too in-depth or were speaking of systems on a much larger scale.Can it be as easy as buying the panels and inverter, and plugging it into a socket, or is there more to it?Some of the articles I was reading had mentioned having to contract with your electrical supplier, having to have an electrician tie it all in in some special/ necessary way, using a battery pack (would this be necessary for a tied-in system?), or using the system to only power single items, like a water heater, or plugging items into a connected battery-pack, all of which I'm not sure is necessary or needed for what my goals/ means are/ would be.
Solar panel produces DC power that cannot be used directly by any electric device at house. Besides, it produces very little current unless its size is big as your roof. To convert DC power into AC power requires even more investment, like a huge storage rechargeable battery bank and very high power DC to AC converter . That is not worth to try it to supply whole house electricity with solar power . That might cost you at least U$20,000 to start with and never ended weekly maintenance. You could only try it just for fun to let it light up a few LED directly without the need to add any extra parts to it.
Q: Can solar panels be installed on public parks or gardens?
Yes, solar panels can be installed on public parks or gardens. In fact, installing solar panels in these areas can be a great way to promote renewable energy, reduce carbon emissions, and generate clean electricity to power nearby facilities or feed into the grid. Additionally, solar panels can provide shade for park-goers and enhance the overall sustainability of the space.
Q: I'm curious, for those who have had solar panels installed on the rooves of their houses:How much did you pay? How much energy do the panels produce? Did it dramatically cut down on your electricity bill? Was it worth it? Thanks!
I say yes, I had a system put in a few months ago. I paid $6K and my utility paid $0K. I should break even in about 6 years. The system is guaranteed for 25 years, so I will have at least 9 years of free energy. I went from a bill of around $200 per month to under $20 in the summer. I will pay a little more in the winter months because less daylight, but I don't use as much energy in the winter. Each year electricity goes up an average of 5%, so while my neighbors have a larger bill each month, I'll be staying under $50 for a long time. Even without the rebate I would have a break even time of about 0 years, still 5 years of free energy.
Q: Can solar panels be used on agricultural land?
Yes, solar panels can be used on agricultural land. In fact, solar energy systems can be a great way to utilize otherwise unused or unproductive land, providing farmers with an additional source of income while producing clean and renewable energy.
Q: Can it be used on a cellphone so u never have to worry about low battery?
they are a long way from producing enough electricity to keep a cell phone charged. but maybe some day in the future. but as our culture is recognizing the importance of solar electricity they are starting to mass produce solar panels and creating major problems of wast when they get old and stop producing electricity. they are super toxic and shouldnt be thrown away. they will prob have special places set of for those in the future.
Q: How do solar panels affect the property's community engagement?
Solar panels can positively impact a property's community engagement by showcasing the owner's commitment to renewable energy and environmental sustainability. This can inspire and engage community members to consider renewable energy options themselves. Additionally, solar panels can serve as an educational tool, promoting awareness and understanding of the benefits of solar energy within the community.
Q: Hi everyone, I am a novice in solar energy system. I want to know if I am on the right track. Recently I bought a 30 W solar panel, 5 Amp controller, and a 22 Ah battery, how many watts and what kind of INVERTER do I need? I did an research some said 50 W and some said 300 W. And am I right on the 5 amp controller and 22 Ah battery to provide larger output of electric, or the higher the # the greater output for 30 W solar panel?Really appreciate for anyone who help!!!
With a 30 watt panel, producing about 2 amps, your not going to have much power from that. A 22 AH battery will give you 2 AH of usage. A battery should never be drained below 50%. What this works out to be is simply Amp draw for 2 hours. Which equals to 2V light bulb that draws amp for 2 hours. Not much. Now to replace that usage with your 30 watt panel, provided the panel is clean and in max sunlight, it will take 6 hours. If you attach an inverter to your system for 5 Volt Usage then the DC voltage drawn from the battery is very high. Example: Say you use a 5 Volt component that requires 50 Watts per hour to operate. The inverter will draw 5 Amps out of the Battery every hour to operate that component. That gives you and /2 of use before the battery is down to 50%.. Maybe that will be enough to charge up a standard Laptop battery. I have 2 30 Watt panels that produce 5 Amps, 4 6V batteries that have 480 AH and a 25 Amp Controller with a booster that increase the amp output to 20 Amps per hour. I live full time in an RV and raise the panels to get max output when I am parked. This system provides me with all the 5V throught the 500 Watt inverter that I need. Good luck on you system.
Q: How much energy can solar panels produce?
The amount of energy solar panels can produce depends on various factors such as the size and efficiency of the panels, the location and climate, and the amount of sunlight available. On average, a typical residential solar panel system can generate anywhere from 4,000 to 8,000 kilowatt-hours (kWh) of electricity per year. However, larger commercial or utility-scale solar installations can produce significantly more energy, potentially reaching several megawatts of power.
Q: Can solar panels be installed on warehouses or industrial facilities?
Yes, solar panels can be installed on warehouses or industrial facilities. In fact, these types of buildings often have large rooftops or open spaces that are ideal for solar panel installations. This allows them to generate clean and renewable energy, reduce their reliance on traditional power sources, and potentially save money on energy costs.
Q: Can solar panels be installed on a warehouse or industrial facility?
Yes, solar panels can be installed on a warehouse or industrial facility. In fact, these large rooftops often provide ideal conditions for solar panel installations, as they have ample space to accommodate a significant number of panels. Installing solar panels on warehouses or industrial facilities can help offset energy costs, reduce carbon emissions, and contribute to the organization's sustainability goals.
