Q: What is the average payback period for solar panels?: The average payback period for solar panels is typically between 6 to 10 years. However, this can vary depending on various factors such as the initial cost of installation, location, energy consumption, government incentives, and local electricity rates.

Q: I'm part of the Sustainability group at school, the school principal is a d**k and doesn't care about the environment, he only cares about money.Me and the group will be talking in front of him and the school council (the people in-charge of the school's money) To convince them to put solar panels on the school roofs.I know that it definitely will help the school save on electricity bills, but it WILL cost a lot of money to put them in.In the end we just wanna reduce carbon emissions!HELP :): When okorder / Good luck but the best way to win is to find a way to get it done and then they can't say no.

Q: im aware i dont fully understand. but with what i do. if P = iv, and current changes with voltage, whats the point of changing either. if in any cicumstance, you end up with the same wattage, how does changing either effect a solar setup. (2v panel vs 24v)thanks in advance. explain in laymans if you can.: The choice of solar panel voltage comes down more to what the panels will be connected to. You're right that power can remain the same at the different voltages. Higher input (panel) voltages are sometimes used in inverter systems to reduce the effect of voltage draw-down. 2v panels (about 20v open circuit) work well for charging 2v batteries, connected in parallel, through a charge controller. For use of a grid-tie inverter, higher input voltages are sometimes used to reduce the effects of draw-down. You want to select and wire (parallel vs. series) your panels based on the input voltage requirement of the load, whatever it may be.

Q: I know what they do and how they work, but at this point they're expensive, don't always produce enough electricity as needed, and can't be used when there's no sun, as in half the day. Wouldn't wind power seem so more efficient? Or if they do use solar panels, how about putting them in the desert. But I really believe that research money should go to fusion generators since that's the future and the answer to our problems. Which is best in your opinion?: It absolutly depends on where you live. I don't have enough wind in my area for a wind turbine to do any good. I just installed solar, the system will pay for itself in about 6 years. I didn't get a system that will zero out my electcity usage, but it will dramatically be decreased. I can always add to it in a few years. Since I plan on living here forever I will see a great financial benift.

Q: Can solar panels be installed on factories or manufacturing facilities?: Yes, solar panels can definitely be installed on factories or manufacturing facilities. In fact, these large industrial buildings often have expansive roof spaces that are ideal for installing solar panels. By harnessing solar energy, factories and manufacturing facilities can significantly reduce their reliance on traditional energy sources, lower their carbon footprint, and potentially save on electricity costs in the long run.

Q: I'm doing a project for school where I will buy a solar panel and utilize/improve the power output of the panel. I want the panel to have an improved amount of energy output compared to the original. My budget for the solar panel itself is ~$00. Anything else that will be needed is covered.Also, I will be comparing the power by lighting a light bulb and checking to see the output energy of the panel.Where or how should I approach this project?What are the parts of the solar panel that I will need to buy?What factors could I change/improve to improve the overall energy output?What are the things (other than the panel) that I will need to buy?How can I attach a light bulb to the solar panel?: Solar okorder /

Q: I need a 2v (500-800ma) solar panel that in can fit on a 24inx4in flat surface. Where can i get one this size and with this power?: Hey Jeff, what you're talking about is frequently referred to as a, solar battery maintainer. There are lots of places that make and sell them, I have seen them in many auto parts stores and truck stops along the freeways. Go to google and search for a solar battery maintainer, they come is sizes similar to what you are searching for, but it will be difficult to find one that is not over 4 wide. Lots of them are about the size of the top of a shoe box, maybe 2 X 6, and come with a cigarette lighter cord attached. A 2 volt model at 500 ma, or /2 amp, works out to about 9 watts, assuming the 2 volt nominal voltage panel is actually optimized for 8 volts, as most of them are. These devices are designed to sit on the dash board of your car and keep your battery charged if you leave the car for a long period of time, like at the airport for a week in the winter. They actually work for that, we've used one before. What are you planning on doing with it? Charging a battery or running a device directly? Remember if you hook it straight to a device, and the current requirements of the device are less than the available sun will develope with your panel, the voltage may climb to a level too high for your device. If you're charging a battery, this does not cause a problem. Another option is to build your own. It can be a lot of work for just one panel, I've not done it myself, but there are videos on the subject. That device in real goods is a flexible panel, known in the solar world as, Amorphous. They are still a bit experimental, the ones they made a few years ago did not hold up as well as the solid ones, and they are expensive. You can get a /2 amp maintainer for around $25. Good luck Jeff, and take care, Rudydoo

Q: Can solar panels be installed on a museum or cultural institution?: Yes, solar panels can be installed on a museum or cultural institution. Installing solar panels can help these institutions reduce their energy costs and carbon footprint, while also showcasing their commitment to sustainability and environmental stewardship. Additionally, solar panels can be installed on rooftops or in nearby open spaces, minimizing any aesthetic impact on the museum's architecture or surrounding areas.

Q: How do solar panels and heaters work?: Well ill start with the slorar panels, they work how there are cells in the panel and when the sun shines on it and reflects off the cells and produces energy. Next the heater is just a plane heater with a object that stores up heat over time when its on and makes it hot and the room and thats amde by a tank or whatever its connected to,to transfer heat

Q: How do solar panels affect the property's carbon footprint?: Solar panels can significantly reduce a property's carbon footprint by generating clean and renewable energy from the sun. Since solar panels produce electricity without emitting harmful greenhouse gases, they help to offset the carbon emissions associated with traditional energy sources. By using solar energy, properties can reduce their reliance on fossil fuels and make a positive impact on the environment by reducing their carbon footprint.
