Q: Ok Im trying to power my room using solar panels and I've figure out that I need about 700 watts to do so, but I really only use my electronics at night. I was wondering if I could buy lets say a 200 watt solar panel and let it charge a battery all day would that work? I live in southern california so I dont have to worry to much about cloudy days. also any suggestions on where to buy a panel, inverter, charge regulator, and battery?
Solar panels range fromwatt to 200 watts. Most panels up to30 watts are 2volts. Siemens puts out a module (SM0) that is rated at 0 watts, 2volt, and 6.3 amps.weight (without a frame) .5 kg ms 660mm by 36mm., .868 sq meters, 26.73 watts/m^2. Do a google search for solar panels. Southern Cal. should have lots of suppliers. I know there is one in Arizona.
Q: Is there any way to charge my laptop with a solar panel? Is there any panel like that. Or if I work on panels can I do something like that. If you know anything about it, can you just help me? Thanks a lot.
Deep Cycle Series batteries are designed to have a large amount of stored current discharged between charging sessions, with very heavy non-porous battery plates to withstand repeated major discharging and charging cycles (deep cycles). They are typically used where the battery is discharged to great extent and then recharged.
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: Can solar panels be used for powering remote monitoring systems?
Yes, solar panels can be used to power remote monitoring systems. Solar panels capture sunlight and convert it into electricity, which can then be used to power various devices and systems, including remote monitoring systems. This makes solar panels an environmentally friendly and cost-effective solution for powering such systems in remote locations where access to the electrical grid may be limited or non-existent.
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?
i think that they are effective, even tho they cost heaps to get installed, i think that they are worth it. They dont require any effort to operate and use natural sunlight that turns into energy that people use everyday. they may be an eye sore but think of how much they are helping the earth and they are a great alternitave to fossil fuels (which are running out anyway), the only problem that i think they would have would be in winter when there isnt much sun on a few days. but other than that they are great
Q: What are the maintenance requirements for solar panels?
The maintenance requirements for solar panels typically involve regular cleaning to remove dirt and debris, as well as ensuring that they are not shaded by nearby trees or structures. Additionally, occasional inspections for any signs of damage or malfunction are recommended, and if necessary, repairs or replacements may need to be carried out by a professional. Overall, solar panels are known for their low maintenance needs, making them a cost-effective and sustainable energy solution.
Q: How do solar panels convert sunlight into electricity?
Solar panels convert sunlight into electricity through the photovoltaic effect. When sunlight hits the solar panels, it interacts with the semiconductor material, usually made of silicon, which causes the electrons to be excited and flow freely. This flow of electrons generates an electric current, which can be harnessed and used as electricity.
Q: but is that per day, per hour or minute?How much watts does the average AC unit use?How much does an energy efficient lightbulb use?All in all let's hypothetically say we no longer use the electric company for our energy source, How many of these panels do you estimate it would take to supply our small home?
To calculate an estimate of your power usage, follow the first link below. Although you can have whatever sized system you want (at a cost) those on solar power generally keep their power usage down by cooking on gas, not using an electric kettle, using low energy light bulbs. Powering AC would up your power requirements considerably. We run a medium sized house on 860 watts of panels in southern Spain (plenty of sunshine). That includes the washing machine, pool, and running two laptops and wireless network all day,and a ceiling fan on summer nights. Hower we cook on gas, would not consider AC, and the fridge runs on gas (though if the fridge had to be replaced I would buy electric and add an extra pv panel). For an overview of the equipment required and what it does, check the second link below.
Q: I purchased some small 3.6 v 70mA solar panels online. I have no experience with solar panels. I am confident of the layout of the parallel circuit I want to create, however I don't know how to properly connect the tabs that come from the sides of the panels. Any help on connecting them?
You must connect solar cells the same way you would connect a couple of batteries, in series. And you cannot connect any form of voltage source in parallel to one another, this doesn't work, if you need a specific drop in voltage from the cell, use a voltage regulator and some capacitors. Hope I helped.
Q: That one costs money but looks like it might work. I don't really have the money for it but if it works then it would probably be worth it. Do homemade solar panels really work or is it just a gimmick? I'm really interested to see if anyone has actually tried this and to see what they say about it.Thanks
The technology of the solar panels is way beyond any DIY project. You can buy pre-assembled panels and install them, but you also need the devices to make the DC they generate into the AC your home needs. Also you will need the batteries for the nights and the times when the sun does not shine. Solar/ photo voltaic generation does work but is not a cost effective way to reduce your reliance on the electrical grid as of this time. They cost 2 arms and a leg, and take many years to come close to break even on the electrical savings. Do a search on the amount of power each panel will generate and then compute how much power you need and what the costs are. I believe in solar power, but not for an individual residence is it practical. Good luck.
