Product description

A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon

Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.

Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Q: What do I need to use this as a battery charger
I hope this will help you choose your charge controller / battery charger more effectively. Good luck!
Q: Can solar panels be installed on sports stadiums or arenas?
Yes, solar panels can be installed on sports stadiums or arenas. In fact, many stadiums and arenas around the world have already installed solar panels to harness clean and renewable energy. These panels can be mounted on the roof or other suitable areas of the facility, helping to offset energy consumption and reduce carbon emissions. Additionally, the large surface area of stadiums and arenas provides ample space for solar panel installation, making them ideal candidates for utilizing solar energy.
Q: I have a 2 volt deep cylce Everstart battery with 845 cranking amps, and a Grape Solar GS-S-250-Fab5 250-Watt Monocrystalline Solar Panel . I use them to power a 48Flat screen TV, a Roku, my 65 watt consuming MacBook Pro, and a 65 watt Fan.I know from previous experience that just the battery, an inverter, and the fan, that the fan will blow for 0 hours straight.Should I really be concerned with a Charge Controller?
Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.
Q: How much energy can solar panels generate?
The amount of energy that solar panels can generate depends on various factors such as the size and efficiency of the panels, the amount of sunlight received, and the geographical location. On average, a residential solar panel system can generate between 10 to 20 kilowatt-hours (kWh) of electricity per day. However, larger commercial or utility-scale solar installations can generate significantly more energy, sometimes even in the megawatt range.
Q: Can solar panels be used to heat water?
Yes, solar panels can be used to heat water. Solar water heating systems use the sun's energy to heat water, typically through the use of solar thermal collectors. These collectors absorb sunlight and transfer the heat to water, which can then be used for various purposes such as bathing, washing, or even space heating.
Q: They have been around long enough to be cheaper. Unless they are made out of a natural material that is rare and hard to find, there is no reason why they should be so expensive. On another note, I think that all low power devices like cell phones and even laptops should have solar panels. Even if it is not enough to fully power the device for a long period of time, it will provide some electricity savings and with millions of people saving a little power adds up.
We all would love to have solar panels, I wish I could afford them for my house! The fact of the matter is that the amount of energy used to make solar panels doesn't really make it beneficial. They would have to have a better way of manufacturing them, a way that uses less energy. Basically they don't make up for the energy lost in their production .Despite our efforts there is no fuel like fossil fuel.
Q: Can solar panels be used in conjunction with a backup generator?
Yes, solar panels can be used in conjunction with a backup generator. This setup is known as a hybrid solar power system and it allows for continuous power supply even during periods of low sunlight or when the solar panels are not generating enough electricity.
Q: Can solar panels be installed on a carport?
Yes, solar panels can be installed on a carport. In fact, carports provide an ideal location for solar panel installations as they offer ample space and a suitable angle for harnessing sunlight. This allows for the generation of clean and renewable energy while also providing shade and protection for vehicles parked underneath.
Q: Are there any fire hazards associated with solar panels?
Yes, there are potential fire hazards associated with solar panels. Although solar panels themselves do not typically catch fire, electrical malfunctions or faults in the wiring, inverters, or connectors can lead to overheating and fire. Additionally, if a fire breaks out in the surrounding area, solar panels can hinder firefighting efforts by creating potential electrical hazards and obstructing access to the roof. Therefore, proper installation, regular maintenance, and compliance with fire safety regulations are crucial in mitigating these risks and ensuring the safe operation of solar panel systems.
Q: i am starting to consider getting solar panels instead of paying electric bills which are somewhat higher now than they used to be
Depends on the size of the house and the average number of sunny days in your location, and how careful you are with your usage. Many houses too have solar panels that only provide part of the electricity needed. A medium sized house in a sunny climate might need a 4.0 kW system, which could mean6 x 250W solar panels,a roof area of 27 sq meters.The average energy use in a sunny country like Australia is 20 kW of electricity a day. To catch that much electricity on your roof you need a 4.0 kW system. In Australia you can buy reasonable quality systems for about $2 a watt (factoring in federal government rebates). This means a 4.0 kW system might cost $8,500. This is not cheap, so it makes sense to cut down your energy use first. :)
