- Q: Can solar panels be installed on a government building?
- Yes, solar panels can be installed on government buildings. Many government buildings have started adopting solar energy to reduce their reliance on traditional energy sources and to promote sustainability. The installation of solar panels on government buildings not only helps to decrease energy costs but also contributes to the overall effort of transitioning to cleaner and renewable energy sources.
- Q: I am seriously thinking about installing PhotoVoltais Solar panels (that generate electricity) on my roof. Besides the usual (cost, ROI, etc.), I was researching for the maintenance of these panels. We have tall trees around the house and needles and leaves fall on our roof all the time... not to mention the dirt and grime that collects over time.Do these decrease the capacity of the panels? Do the panels require a regular maintenance?Thanks!
- panels need full sun. any shade reduces out put. leaves left on them will cause the individual cells burn out. they nneed adjusting every season, an washed with a soft cloth once a year.
- Q: I have an electric bicycle that I travel to work by, pulling a modified child carrying trailer that holds two 2 volt deep cycle batteries in series to power the 24 volt bike motor. I'm thinking about adding a 50 watt solar panel (or larger depending on the room I can make available) to charge while I'm at work and to provide some extra juice while on my more distant travels.Can I get a solar panel to charge them while they're connected the way they are: in series? Does charging work that way?I've read that in order to charge the 24 volt battery setup (if the answer to the Q above is yes), the output from my solar panel would need to be a little more than 24 volts. Is this true? If so, how many volts?Since the bike is supposed to be powered at 24 volts and I have an x-volt (x gt; 24v) solar panel connected to it, will this cause any damage to the controller or other components while running them?Will it help supply power even while the motor is being run?Thanks.
- Charging voltage = 2*3.8 = 27.6V Current regulated to AH rating divided by 0 Charging time = 0 hours
- Q: I have the wattage of solar panel but i dont know about the voltage amp; current rating of it. Plz explain me about the voltage rating of solar panel.
- The voltage rating and current rating are part of the specifications for the panel. You will have them listed on the spec sheet. The voltage number is usually the open circuit voltage of the panel, the voltage with no load. The current number is the short circuit current of the panel. In use, you need special electronics, called a Maximum Power Tracker (MPT) controller, which adjust the load to get the most power from the panel, and adjust the voltage output via a DC-DC converter to the optimal conditions to charge the attached battery. how to take batteries as per solar wattage ? sorry, don't understand this.
- Q: When people buy small solar panels, what are the steps to making it actually charge or run something.. I'm completely new to this of course and im curious. what kinda of wire and other devices are needed and how do you attach the wire and everything..
- The Earth4Energy kit is the best system for people who are looking to save money on their home energy bill and want to build a energy generator at home .There is no other kit out there in the market like Earth4Energy that explains clearly with manuals or even includes videos. The Earth4Energy kit is available online for purchase. Many people can now have access to alternative solar and wind energy. and u will find step by step instructions
- 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: Can solar panels be installed on a pergola or gazebo?
- Yes, solar panels can be installed on a pergola or gazebo.
- Q: solar panels are way too expensive to buy, can they be homemade cheaply? i want at least 500 watts. everyone on the web sells these instructions, but i'd like a link to free info, if it is really possible for a non-sciencey person to make. thank you
- If you want long term working ones then no. I have not seen the web instructions ones, but solar panels that are manufactured are a lot more complex then simple solar panels that you make in your backyard. Also, you need to have some type of turbine or other thing to change heat energy into electrical energy. For a non science person to try and do this and have it work the first time maybe hard to accomplish.
- Q: How Is heat From the Sun Transferred into Currents From solar Panels? (Explain Deeply Please)
- first you should have good solar panels. because it can work well and make electricity quikly. when absorb sunshine it will produce electric charger and make electricity.
- Q: Can solar panels be used to power a water pump?
- Yes, solar panels can be used to power a water pump. Solar panels convert sunlight into electricity, which can then be used to power a water pump. This allows for a sustainable and renewable energy source to operate the pump without relying on conventional electricity grids or fossil fuels.
