- Q:I am researching several solar panels to install in my house. I would like to use a 40 watt panel to connect, through a solar battery controller, to a battery or two. I would then like to use the solar panel (40 watts) to charge the battery(ies) for emergency use. Once charged, and when needed, I would like to use the battery(ies), 2 volt deep cycle, to power several LED lamps. Since I am new to solar power I had several questions...Is a 40 watt panel strong/large enough to charge a 2 volt deep cycle battery or two?How long would it take to charge one of these batteries?What would be the expected cost to purchase necessary supplies? (With the solar panel, battery controller, and MC4 cabling I've found I have an expected cost of roughly $00.00 with batteries)Would this be difficult for someone with little experience in this field?
- Your demand is high. You require at least 5KVA (5000watts) out put with an appropriate battery storage and inverter..
- Q:There are so many solar panels and kits it is very confusing. I need to know what exactly I would need if I had an underground home with no electricity. I want to be totally off the grid with solar power. Someone please explain to me in simple terms what exactly I need. Maybe give me a link to the right kit for me. Also are they easy to install? Are there instructions that I need to download?Thank you

- Q:Can I install my 2v solar panel straight to battery to charge the battery on my 989 ford ranger?
- You would need a inverter which transfer AC to DC. then you can connect it to your battery. You also have to check is your battery able to take energy coming from inverter. This might be little but tricky. Check the energy output and battery Voltage before testing.
- Q:Are there any fire hazards associated with solar panels?
- Yes, while solar panels themselves do not pose a significant fire hazard, there are some potential fire risks associated with their installation and operation. These risks primarily stem from electrical malfunctions, such as faulty wiring, improper installation, or damage to the electrical components. Additionally, in rare cases, solar panels can contribute to the spread of fire by acting as a source of fuel or by hindering firefighting efforts due to their presence on rooftops. However, with proper installation, regular maintenance, and adherence to safety guidelines, the fire hazards associated with solar panels can be minimized.
- Q:How do solar panels affect insurance premiums?
- Solar panels can potentially lower insurance premiums due to the reduced risk of fire and environmental damage associated with renewable energy systems. However, the impact on insurance premiums can vary depending on factors such as the location, type of solar panel system, and the insurer's policies. It is advisable to discuss these specifics with your insurance provider to determine the exact effect on premiums.
- Q:Can solar panels be installed on tall buildings?
- Yes, solar panels can indeed be installed on tall buildings. In fact, tall buildings can provide advantageous conditions for solar panel installations due to their elevated position, which allows for maximum exposure to sunlight throughout the day. Additionally, tall buildings often have large surface areas available for solar panel placement, which can help generate a significant amount of renewable energy.
- 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.
- A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
- Q:Can solar panels be used for powering a water treatment plant?
- Yes, solar panels can be used to power a water treatment plant. Solar energy can be harnessed to generate electricity, which can then be used to power the various processes involved in treating and purifying water. This renewable energy source provides a sustainable and environmentally friendly solution for powering water treatment plants.
- Q:Can solar panels be installed on a barn or agricultural building?
- Yes, solar panels can be installed on a barn or agricultural building. In fact, it is becoming increasingly common for farmers and landowners to install solar panels on their barns or agricultural buildings to generate renewable energy and reduce their dependence on traditional power sources.
- Q:Do solar panels require building permits?
- Yes, solar panels typically require building permits. The permitting process ensures that the installation complies with local building codes, electrical regulations, and safety standards. It also ensures that the structure can support the added weight and that the panels are properly installed to maximize efficiency and durability.
