- 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: hi so im doing a school project thing and they have a lot of different questions for us that help us decide whether we would rather a city have a nuclear reactor, or solar panel. But i cant seem to get the last 2 questions...help please???so question ........What types of emissions, if any, are produced by each type of generating station? Do these emissions affect human health?question 2.....What are the long term financial costs associated with maintaining each type of generating station?thanks!
- You should research nuclear reactors and their emissions. Mostly it's waste heat, and if they use a water-based cooling reactor, there can be significant emissions of water vapor. Some might consider the spent fuel an emission too. Waste nuclear material disposal is a problem. Research it. Solar panels have no emissions during operation, but there is some nasty stuff emitted when they are manufactured. 2: Maintenance of solar panels is pretty straightforward: keep them clean, trim overhanging trees, shrubs, etc., check for and clean corrosion, contaminants, etc. regularly. Maintenance of nuclear power plants, so far, is a full time job for many technicians and engineers. The recently developed portable (the size of a shed) nuclear generators claim zero maintenance for 20+ years. That's a big improvement.
- Q: What is the impact of roof age on solar panels' efficiency?
- The impact of roof age on solar panels' efficiency can vary depending on the specific condition of the roof. In general, an older roof may need repairs or replacement before installing solar panels to ensure proper installation and optimal performance. Additionally, an aged roof may have structural issues or shading problems that can affect the efficiency of solar panels. Therefore, it is important to assess and address any roof concerns before installing solar panels to maximize their efficiency and longevity.
- Q: How do solar panels affect the overall carbon footprint of a building?
- Solar panels can significantly reduce the overall carbon footprint of a building. By harnessing clean and renewable energy from the sun, solar panels eliminate or greatly reduce the need for traditional fossil fuel-based electricity generation. This means lower emissions of greenhouse gases like carbon dioxide, which are major contributors to climate change. The use of solar panels helps to transition buildings towards a more sustainable and eco-friendly energy source, effectively reducing their carbon footprint.
- Q: Can solar panels be installed on greenhouses?
- Yes, solar panels can be installed on greenhouses. In fact, it is a popular practice as it allows for the generation of renewable energy while utilizing the available space on the greenhouse roof. The solar panels can help offset the energy needs of the greenhouse and contribute to a more sustainable and environmentally-friendly operation.
- Q: I want to be more self sufficient and get solar panels for electricity in a small house any tips will help. i need to know how many watts is enough and ect.
- To clarify your thinking, ask yourself whether your goal is really to be more self-sufficient, or to save money. For most people, I think when they say they want self-sufficiency, they really mean they want to save money, not pay more. The money-saving route may come through putting in more insulation on the house, or double-pane windows, or energy-efficient appliances. Solar might play a part, but the kind of solar that pays back well (if at all) is the type without batteries. That doesn't give you self-sufficiency - if the power company has a blackout, the solar electric will automatically disconnect. Your power company may offer a free energy audit to help you save money. And if you are interested in pursuing solar electric (or even better, solar hot water), check with a local installer. They can size your system and give you a free quote.
- Q: Can solar panels be installed on a restaurant or food service establishment?
- Yes, solar panels can be installed on a restaurant or food service establishment. Many businesses in the food industry have successfully adopted solar energy systems to power their operations and reduce their electricity costs. Installing solar panels on rooftops or in parking lots can provide a sustainable and renewable energy source for the establishment, helping to lower its carbon footprint and contribute to a greener future.
- Q: What is the impact of roof shading on solar panels' efficiency?
- Roof shading has a significant impact on the efficiency of solar panels. When panels are partially or fully shaded, the shaded areas produce less electricity, resulting in a decrease in overall energy production. Shading can be caused by nearby trees, buildings, or other structures that obstruct sunlight from reaching the panels. It is essential to minimize shading on solar panels to maximize their efficiency and optimize energy generation.
- Q: I live in a higher LATITUDE so in the winter months, there is a limitation in the amount of sunlight available, but will this impediment restrict the ability of solar panels to function due to the lack of sunlight involved?
- Solar panels work in sunlight, so obviously the more sunlight, the more power. However, ironically, solar panels don't like heat, so they work better in the cold. Higher altitudes often have more sunlight, due to less crud in the atmosphere, and are often colder than lower altitudes, so you will often get better performance in higher locations. We have solar systems working in every continent in the world, including near both the north and south pole.
- Q: Can solar panels be installed in areas with high levels of saltwater exposure?
- Yes, solar panels can be installed in areas with high levels of saltwater exposure. However, it is important to choose solar panels that are specifically designed for these conditions and are corrosion-resistant. This may involve using materials like marine-grade aluminum or stainless steel for the panel frames, and ensuring proper sealing and coating to withstand saltwater corrosion. Regular maintenance and cleaning are also necessary to mitigate the effects of salt buildup on the panels.
