- Q:I have just made my first dolar panel 20 watts, charges my 27TMX Trojan battery perfectly. Now I am thinking to build more solar panels for a grid tie installation at my house, maybe 5 panels would do it, is this safe?
- Congratulations on your solar panel. It takes a lot of work to construct one. Tying to the electric grid requires permission from your power company, and conformance to local building codes. This generally means compliance with the National Electrical Code (NEC), meaning your panels must be UL (or similar rating from another standard) listed, for fire and electrical safety reasons. Homemade panels won't qualify, unfortunately. I really would discourage you from trying to do a jungle installation without permission, as the power distribution in a house is nothing to be trifled with. That would also likely void your homeowner's insurance, and give the bank a reason to call your mortgage, if you have these.
- Q:Can solar panels be used to power a waste management facility?
- Yes, solar panels can be used to power a waste management facility. Solar panels can generate electricity by converting sunlight into usable energy, and this energy can be utilized to power various operations and equipment within a waste management facility, including waste processing machinery, lighting, ventilation systems, and administrative functions. By using solar power, waste management facilities can reduce their reliance on traditional energy sources, lower operational costs, and contribute to a cleaner and more sustainable environment.
- Q:My family has been interested in solar technology for a long time. I want to know how to save money so I can get as many solar panels as possible. I know the government has different discounts/ grants, and there may be tax incentives. I am not looking to sell energy to the energy company I want to use the energy directly.
- Nothing good comes from the government ,nothing .so why would you think they would really help in this matter . If the government is involved , that is a good indicator to stay away.
- Q:how much power is generated with solar panels? also please give me links for that information.and how much would the costs be for this alternative energy source?
- The amount of electrical energy (kWh) a kW grid connected solar PV system will generate on an average day (kWh/kWp.day). There are some factors that will determine just how much electricity you can create with solar panels for your property - The size of the system, the direction that your roof faces and the angle of the roof comes next. For optimum performance, your panels will need to be on a 35-degree angle, facing south.
- Q:Can solar panels be installed on a historic building?
- Yes, solar panels can be installed on a historic building. However, the installation process may require careful planning and consideration to ensure minimal visual impact and preservation of the building's historical integrity. Collaboration with preservation experts, architects, and local authorities is crucial to finding a suitable solution that balances renewable energy goals with the preservation of the building's historic value.
- Q:How do I clean my solar panels?
- To clean your solar panels, start by turning off the system and ensuring the panels are cool to touch. Use a soft brush or sponge with mild detergent mixed in water to gently scrub away any debris or dirt. Rinse the panels with clean water and allow them to dry naturally. Avoid using abrasive materials or harsh chemicals, as they may damage the panels. Additionally, be cautious when working at heights and consider seeking professional help if needed.
- Q:By best I mean safest places. If I were to install them on my roof am I risking due to damage from weathering? Such as rain or snow. I don't get very high winds around here, nor any natural disasters such as hurricanes or tornadoes. Does anyone have solar panels that have been durable for a long time? Is it worth the investment?
- Photovoltaic panels are designed to be put on a roof, exposed (obviously) to sun, but also rain, snow, and wind. Generally, there is even a rating for something like hail. A good mounting system will be stronger than the underlying roof, so will withstand most anything short of a direct hit by a tornado or hurricane. There are a few panels from the 70's (that's the 970's) still in operation, I believe. They look horrible, but are still producing a little electricity. Since then, housings have improved, and panels generally have a 25-year warranty today (some cheap ones are 20-year warranty).
- Q:Can solar panels be used to power a water treatment plant?
- Yes, solar panels can be used to power a water treatment plant. Solar energy can be harnessed through photovoltaic panels to generate electricity, which can then be used to power the various processes involved in water treatment, such as pumping, filtration, disinfection, and distribution. This not only reduces reliance on fossil fuels but also helps in creating a more sustainable and eco-friendly water treatment system.
- Q:What are the supplies needed in a solar panel field, i know there are the panels. But what about batteries, and converters. Possibly other things, and how many will i need, for a certain amount of panels?
- There okorder . I think you can find lots of info on the internet. I hope this helps you get going.
- Q:Can solar panels be installed on a swimming pool?
- Yes, solar panels can be installed on a swimming pool. These panels can be used to heat the water in the pool, reducing the need for traditional heating methods and saving energy costs. Additionally, solar panels can also be used to power pool pumps and other equipment, making swimming pools more energy-efficient.
