Q: The Physics club in our school is trying to convince the Board of Ed to install solar panels in our school, and i was just wondering if anyone with some experience or real expertise in solar energy. I need some points about their usefulness some real pros and cons on maintenance, etc. Anything will help. Personally i would be perfectly for the idea, but i heard that the overall cost of installing them is much higher than the cost of the energy saved and government subsidies, but ive only heard about this.
You have to approach it as an investment. Ignoring the cost of an inverter for net metering, if we consider a 500 W panel installed for $0 a watt which is $5,000 and consider an average of 8 hours of usable sunlight per day, and at a rate of $0.0 per kWh (schools probably get $0.03 per kWh) then the panel would be saving $2.7 per month in electricity. Considering that the panel has an expected lifespan of 20 years, that would give you an internal rate of return such that the monthly rate satisfies the equation: $5,000 = $2.7 * ( ( - / R^24 ) / ( - / R ) - ) By binary method we get R = 0.99588342. Taking this to the 2th power to annualize it we get Ra = 0.9570 which means that we are getting an annual return of -4.83% per annum so investing in the solar panel is the same as making an investment at an interest rate of -4.83% per year. True interest rates are low and you only get about .3% per annum by putting money in a CD but that still beats investing in solar panels which gives you a negative return on your money. Solar panels need to get a lot better before they are a good investment.
Q: How do solar panels affect wildlife?
Solar panels have a minimal impact on wildlife as they emit no harmful emissions or pollutants. While some studies suggest that solar farms may disrupt local ecosystems, the overall impact is relatively low compared to other forms of energy generation. Additionally, solar panels can provide shade and shelter for certain species, benefitting local wildlife in certain cases.
Q: Can solar panels be installed on a metal roof?
Yes, solar panels can be installed on a metal roof. In fact, metal roofs are often considered ideal for solar panel installation due to their durability and longevity. The metal roof provides a strong and stable surface for mounting the panels, and the sleek design of the panels can complement the aesthetics of the roof. Additionally, the metal roof's reflective surface can help enhance the overall efficiency of the solar panels by bouncing sunlight back onto them.
Q: Do solar panels require a specific orientation or angle for optimal performance?
Yes, solar panels do require a specific orientation and angle for optimal performance. Generally, it is recommended to install solar panels facing south and at an angle equal to the latitude of the installation location. This allows the panels to receive maximum sunlight throughout the day, maximizing their energy production. However, panels can still generate electricity when facing other directions or at different angles, although their efficiency may be slightly reduced.
Q: What is the warranty on solar panels?
The warranty on solar panels typically ranges from 10 to 25 years, depending on the manufacturer.
Q: Can solar panels be installed on concert venues or music festivals?
Yes, solar panels can be installed on concert venues or music festivals. In fact, many event organizers are increasingly adopting solar energy to power their events, reducing their carbon footprint and promoting sustainability. Solar panels can be installed on rooftops, parking lots, or even as temporary structures to generate clean and renewable energy for the venue's electricity needs.
Q: We have LED at the output of 40 watts and is used for 0 hours giving us 400 Watts-hr of energy consumed.Rechargable batteries needed are 2 V. 400/2 gives us 34 Ampere-hour battery needed. If we want it for 3 days, It would be 34x3=00 Ah. So the battery needed 00 AhNow how do I select the solar panel which can charge this/these batteries? What should be its rating?
First, you need to make sure that your battery can take a regular 34Ah discharge without damage. The usual wisdom when using deep cycle lead-acid batteries is to allow for no greater than 50% discharge. This is to prevent the battery from ageing prematurely. Note that automotive batteries are not usually considered suitable for deep-cycle applications. Best allow for at least 200Ah capacity. Your solar panel capacity needs to take into account that whatever the nameplate output of the panel, that will be what it will produce under ideal conditions, actual output will always be less, often quite a bit less. You also need to allow capacity to cope with dull, overcast days when the light level is very low. You can get solar maps that will give you the sunshine hours and irradiation levels at your location. The solar panel capacity ends up being a juggling act between available funds/space and how critical it is that the light always works as desired. Let's say you had a 400W panel, which sounds quite generous. In the middle of winter, it may produce only 75W for 5 hours on a dull day, not quite enough to run the light for 0 hours. Would you expect several such days in a row? How many days could a 00Ah of battery capacity cover under these conditions?
Q: How long does it take to install solar panels?
The installation time for solar panels can vary depending on several factors such as the size of the system, complexity of the installation, and the availability of the necessary equipment and manpower. On average, a residential solar panel installation can take anywhere from one to three days. However, larger commercial installations may take longer, potentially a few weeks or more. It is best to consult with a professional solar installer who can provide a more accurate estimate based on your specific project requirements.
Q: Can solar panels be installed on a theater or entertainment venue?
Yes, solar panels can be installed on a theater or entertainment venue. Solar panels can be mounted on the roof or other suitable areas of the building to harness solar energy and generate electricity. This renewable energy source can help reduce energy costs and carbon footprint for the venue.
Q: How much does 000 square feet of solar panels cost? This is for a pool with dimensions 75ft by 25ft? How much will it cost including installation fee and the water heater?
Are you asking about solar water heaters or solar electric panels?
