Q:my solar car works when using the Battery but when there is sunlight i connect the wires to the solar panel and it does not work...................HELP

If that solar panel came with the car, the panel is most likely defective. Make sure you're in bright sunlight, and try holding the car so that the wheels are not touching the ground. If the wheels still won't turn, even slowly, then the panel is bad. If each person in the class got one, see if you can try your panel on a friend's car, or their panel on your car. If this is just any little panel, it could be that the panel simply does not have enough voltage, current, or both to power the motor on the car.

Q:A few months ago my dad said something about getting solar panels, and how green they were. I was just wondering if there were any companies that sold them and if they would actually make a big difference.

Yes there are companies that sell solar panels, many of them specialize in solar, a simple google search with your state or city name and the word solar should get you many results. There are actually two kinds of solar panels that get installed on homes, one kind creates electricity, the other heats up water. Depending on how large a system you installed, you could have all of your electricity or hot water powered by solar, which would mean you'd use less nonrenewable resources like coal, oil, or natural gas. The other difference the solar panels would make would be in your electric or gas bill, that number would go down right away, but you'd have to wait a few years before the money you save there would cover the cost of buying the panels, the number of years depends on your state, and the size of your system. Starting in January there will be a 30% federal tax credit, that would mean savings for every installation in the US. Also a lot of states now have a rebate program, which means the system is even less expensive.

Q:The battery is 9ah and the solar panel is 20w

Yes, certainly. So long as the solar panel's voltage exceeds the voltage of the battery (which is probably going, certainly if it can be a discharged battery, which is lower than 2 volts), then it will recharge the battery. Additionally, a 2 V solar panel can produce bigger than 2 volts. Nevertheless, the rate of charging is more likely to be depdendent on the availabilty of daylight. And of course, the better the capcity of the battery, the longer it takes to cost.

Q:Exactly How much power will this kit produce? for example. Will it only be able to power the 2 light throughout an entire day or would it be able to power a couple TV's with a couple lights. Or a Refrigerator? washer dryer? I'm just wondering exactly what it will be able to do and if it's worth paying $200 for if it'll only power two lights. Don't get me wrong, That's great and will make a difference but i'm looking for something that will make a little bit of a bigger difference. Would the 80 watt monocrystalline solar panel be much better? if so, what would it be able to power? double?

Yes, 80 watts will be nearly twice as useful as 45 watts - but 80 is still a small number. Solar panel systems need an inverter and there's a slight energy loss at the inverter. And, if you want to use the day's energy at night, you'll need a battery or two. And every time you move energy into or out of a battery, you lose a little of the energy. All this is to say that you need to sum up the wattage of your appliances and add a fudge factor to accommodate for the losses. I looked at the kit and was moderately impressed. $200/45=$4.44/watt; that's a reasonable price but the links I left below talk of prices as low as $2.58/watt. Also the Harbor Freight kit doesn't contain an 'inverter' which you would have to buy. Also the wattage advertised for any solar panel assumes the thing is clean and pointed right at the sun on a clear day.

Q:Can solar panels be used on commercial buildings?

Yes, solar panels can be used on commercial buildings. In fact, many businesses are embracing solar energy to reduce their carbon footprint and save on electricity costs. Installing solar panels on commercial buildings not only helps generate clean and renewable energy but also provides long-term financial benefits for businesses.

Q:Can solar panels be used in areas with high levels of electromagnetic interference?

Yes, solar panels can be used in areas with high levels of electromagnetic interference. However, it is important to ensure proper grounding and shielding techniques are implemented to minimize the impact of electromagnetic interference on the performance and efficiency of the solar panels.

Q:How do solar panels affect the local job market?

Solar panels can have a positive impact on the local job market by creating new employment opportunities. The installation, maintenance, and manufacturing of solar panels require skilled workers, thus leading to job growth in these sectors. Additionally, the shift towards renewable energy sources like solar power can stimulate the local economy through increased investments and business development.

Q:How much energy can solar panels produce?

The amount of energy that 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 between 10 to 20 kilowatt-hours (kWh) of electricity per day. However, larger commercial systems or those installed in regions with abundant sunlight can produce significantly more energy.

Q:My dad owns a restaurant, and we are doing farely well, but we were thinking on installing solar panels to minimize electricity costs (and of course make it greener). My dad would like to hear some numbers on the price in today (August 29/202) and savings he could possibly make over the years. So In Total Here's What I'm Asking:) Would it be hard to install?2) Maintanence?3) Monthly Expense? (None?)4) Price?5) Savings over time?6) Pros/ConsThank you so much!

To begin with, you need to know how much power you need and then decide from there just how much you can or will have to pay to get that money back. Find a couple companies that do this kind of work to give you some figures to work with

Q:Are there any aesthetic considerations when installing solar panels?

Yes, there are aesthetic considerations when installing solar panels. The design and placement of solar panels should be mindful of the overall appearance of the building or property. Factors such as panel color, size, orientation, and integration with the existing structure are important to ensure that the solar panels blend well with the surroundings and do not compromise the visual appeal of the property.
