Q: solar panel capacity, how do it work
Calculating Your Solar Power Requirements There are three main things to consider in order to choose a Solar panel or create a Solar system. : How much energy can your battery store? 2 : How much energy will your appliance(s) use over a period of time? 3 : How much energy can a Solar panel generate over a period of time?
Q: Can solar panels be installed on a landfill or waste management site?
Yes, solar panels can be installed on a landfill or waste management site. In fact, landfills and waste management sites can provide suitable locations for solar installations due to their large available space and minimal shading. Additionally, installing solar panels on these sites can help utilize otherwise unused land while also providing renewable energy generation and reducing greenhouse gas emissions.
Q: Can solar panels be used to power a greenhouse?
Yes, solar panels can be used to power a greenhouse. Solar panels convert sunlight into electricity, which can then be used to power various electrical systems in a greenhouse, such as lighting, ventilation, heating, and irrigation. This renewable energy source offers an environmentally friendly and cost-effective solution for greenhouse operations.
Q: Ok so I am planning on buying a solar panel. I am doing it to possibly sell the energy that it stores. It is a 20 watt panel so I am just wondering if every week or month if I sold that energy that it stored would make me a good profit. I am not hoping for thousands of dollars a month..just like 00? The solar panel cost me $,00 so if so, how long do you think it would take to make good profit. Also, how much would I make every week or month?
I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel /solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.
Q: Polycrystalline solar panels are good or single crystal solar energy is good
Pre-monocrystalline silicon solar cell photoelectric conversion efficiency of about 15%, the highest reached 24%, which is all types of solar cells in the photoelectric conversion efficiency of the highest, but the production cost is so large that it can not be a large number of extensive And commonly used.
Q: Can solar panels be installed on a pole or ground mount?
Yes, solar panels can be installed on either a pole or a ground mount. Pole mounts are typically used in situations where there is limited space or if the panels need to be elevated for better sun exposure. Ground mounts, on the other hand, are more commonly used in larger installations where ample space is available. Both options provide flexible solutions for installing solar panels.
Q: I riped two solar panels out of some solar light and tested them. I found out that they both produce 2 volts(I have no idea on the watts or amps). Iquot;ve hooked them up to an electric motor that can be driven by a AA battery, but when I hook the solar panels up to them nothing happens. What is wrong?
Mark G has a good answer. If you leave your voltmeter on the solar cells when you hook up the motor, you will see the voltage drop to near zero. Same thing would happen if you tried to use 2 9 volt batteries to start your car. They just cant maintain the voltage when high curent demands are made.
Q: hey, i am wanting to help our earth a little bit, and I was wondering how to do a solar panel connection for powering my home.... i just want to reduce my energy bill a little bit, Would these solar panels work?and how would i connect them?
Hello, Yes you definitely can use this kind of panels. Powering your home entirely will be an issue if you are not familiar with solar energy and electricity in general. If it's the case I'm afraid you'll need a specialist. The basic principle of a solar power system: - Solar panel to charge the batteries - DC to AC converter that will convert the DC voltage from your battery to AC voltage so that you can connect regular home appliances like lights or TV.
Q: Simplfy it so i can understand pls and put it in stages such as . sun hits solar panel plsHow many different types of solar panels are there?
The term solar panel is best applied to a flat solar thermal collector, such as a solar hot water or air panel used to heat water, air, or otherwise collect solar thermal energy. But 'solar panel' may also refer to a photovoltaic module which is an assembly of solar cells used to generate electricity. In all cases, the panels are typically flat, and are available in various heights and widths. An array is an assembly of solar-thermal panels or photovoltaic (PV) modules; the panels can be connected either in parallel or series depending upon the design objective. Solar panels typically find use in residential, commercial, institutional, and light industrial applications. Solar-thermal panels saw widespread use in Florida and California until the 920's when tank-type water heaters replaced them. A thriving manufacturing business died seemingly overnight. However, solar-thermal panels are still in production, and are common in portions of the world where energy costs, and solar energy availability, are high. Recently there has been a surge toward large scale production of PV modules. In parts of the world with significantly high insolation levels, PV output and their economics are enhanced. PV modules are the primary component of most small-scale solar-electric power generating facilities. Larger facilities, such as solar power plants typically contain an array of reflectors (concentrators), a receiver, and a thermodynamic power cycle, and thus use solar-thermal rather than PV.
