- Q: I need to power a series of meraki wireless repeaters that plug into a standerd wall outlet. consuming 5v or .08 amps However I need this in a remote location (like out in the middle of nowhere) Using A solar panel as power supply and a battery to store the energy but, how and what do I use to convert the energy coming from the solar panel to the battery and the batteries power supply to match the needs of the meraki wireless repeater? How do I make this as compact as possible? Do I need a ac/dc converter? or dc/ac converter? Any suggestions or solutions would be great !
- Search the web for some of the inexpensive solar Cell Phone Chargers. They can be hooked in series or parallel as needed to get you teh voltage and current needed. The 80mA is not too tough, thats not much current. Suggestion is to use a battery that is constantly trickle-charged by the solar panel. This will assure operation on a cloudy day or at night. Another strange source for solar panels and solar charge systems is, believe it or not, Harbor Freight Tools. they are on the web as well as have stores all over.
- Q: Can solar panels be used for air conditioning?
- Yes, solar panels can be used to power air conditioning systems. Solar panels generate electricity from sunlight, which can be used to operate air conditioning units. This allows for cooling without relying on traditional electricity sources, reducing energy costs and environmental impact.
- Q: Can solar panels be installed on a sports stadium?
- Yes, solar panels can be installed on a sports stadium.
- 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!
- I don't know if the guy is right about cells burning out if they are covered. You should look on the Internet for insolation tables for your area to see the effective hours of sunlight. Then guesstimate the percentage of time the panels will be shaded. Those trees may make the solar thing a poor idea. He is right about the trees reducing you efficiency. If a panel is shaded about 0 percent, its output drops to close to zero. My panels are five years old, and I have washed them twice. There as been no noticeable dropoff in output.
- Q: I have a college project due within a week, and it involves a 00 Watt solar panel and a 2V 7.5Ah Battery. I got the project finished up and producing free energy for my house in September, however recently the battery I bought, that was specifically made to hold Solar Power, lost its charge (unsure how or why) and it is pretty much useless. Can I just go to a store and buy any 2V car battery to use?
- well the thing to remember just like any rechargeable battery they don;t respond well to continues charging they need some down time to discharge and then recharge. during the charging process the liquid or battery solution get hot and even evaporates. Replacing the battery solution with water won't work when your battery has lost it's solution you need to get battery acid replacement or battery repair solution. this is sold in many location near where the batteries are sold. check your spec for your solar panel out put and take those specification to your local auto store and they might even suggest an over sized battery. you might consider adding an additional battery in series for additional power storage.you might also using a light sensor and cut off switch solenoid which which stop charging or which would also stop and current from returning back to the panel. if you have every own a small car the battery is much smaller than that of a pick up. be sure that you don't get the small battery look for a large heavy duty battery all sold in the same store.
- Q: What is the lifespan of solar panel batteries?
- The lifespan of solar panel batteries can vary depending on various factors such as the type of battery, its quality, and usage patterns. Generally, solar panel batteries are designed to last between 5 to 15 years. However, with proper maintenance and care, some batteries have been known to last even longer.
- Q: Can solar panels be used in off-grid systems?
- Yes, solar panels can be used in off-grid systems. Off-grid systems are designed to operate independently from the electrical grid, and solar panels can generate electricity from sunlight, making them a reliable and sustainable source of power for off-grid applications.
- Q: Can solar panels be installed on military bases or installations?
- Yes, solar panels can be installed on military bases or installations. In fact, many military bases around the world have already incorporated solar energy as a part of their sustainability initiatives. Installing solar panels on military bases not only helps reduce their reliance on traditional energy sources but also enhances their energy security and resilience.
- Q: i need technical and non technical details to generate MW power by solar panels
- First off, you should consider cost per kilowatt-hour (kWh) since kWh is energy whereas MW is power, and kWh is a common unit of energy used by power utilities. But first you would need to design the power capacity required, which as you state, is assumed to be MW. Average system costs = $95 per square foot Average solar panel output = 0.6 watts per square foot Average solar energy system costs = $8.95 per watt Form this information, the capital cost of installing MW = $8.95 /W * 0^6 W/MW = $9 million. The lifetime of a typical solar power system is probably about 20 years. Assuming a true MW peak output of the solar panel it would be anticipated that a daily average energy production would be peak output over about 3 hours per day, or 3 MWh of energy per day. Total production over a 20 year system life would be 3 MWh * 365 days/yr * 20 yr = 22 x 0^3 MWh So in terms of costs of capitalization of the system, the cost of Energy (/kWh) = $8.95 million / 22 x 0^3 MWh = $0.40 / kWh (approximately) This cost does not include maintenance, however, given the simplicity of these systems; other than periodic equipment replacement, which is covered by specifying a 20 year complete system replacement; other maintenance cost should be relatively low. The required surface area of solar panel = 0^6 W / 0.6 W/ft^2 = 94,340 ft^2 or a little over 2 acres of panel surface area. To be able to properly access and maintain the solar array, the minimum area required would likely be 5 to 0 acres.
- Q: Can solar panels be installed on a warehouse or storage facility?
- Yes, solar panels can be installed on a warehouse or storage facility. In fact, these types of buildings often have large, flat rooftops that are ideal for solar panel installation. Installing solar panels on warehouses or storage facilities can help generate clean and renewable energy, reduce electricity costs, and contribute to sustainability efforts.
