275W Poly Solar Panel for Small Solar System Stock Information
- Q: My hubby and I are waiting to move in to our camper but have to figure out how many solar panels, batteries, etc. to get. I can't find the info per appliance for Watts and amps, but does anyone have a good, general idea of how many Watts it'd take to run the whole shabang? It's a 999, 25-foot Sportsmen tag-a-long, if that helps..It's got the following, and we'd like to run the propane things off of electric:*Refrigerator/freezer*Microwave*Oven/stove*AC/Heat*Will have a tv, phone chargers, laptop charger, but those will be unplugged when not in useThanks so much! It's such a headache.. You get SO MUCH different info from different places.. OI..
- With an RV, you can find lithium bromide water chiller based refrigerators and air conditioner that run mostly on propane with just a little bit of electricity for a pump and fans. The oven, stove and heat, you can also run off propane. A Microwave is probably 750 watts but only operates for a few minutes at a time. You'll just have to go through everything item by item and figure out how many watts each one will draw and how long each will run per day to size your solar panel. Don't forget that the sun will only shine for a few hours each day. In general, for a camper, the target isn't to produce all the power you need but to slow down the drain on the battery bank to last till you get back onto the road where the engine can recharge the batteries. Keep in mind that the lithium bromide chiller systems only operate when stationary and level so some people opt for conventional electric systems just for convenience which sounds like what you're trying to do. Best way to figure out how much power each is drawing is by measuring it while in use. It may be worth it to put a meter on the battery bank and go camping one weekend with a generator or put a meter on the main circuit breaker panel and camp where power is provided, just to see what your typical use is. You're far better off running as much as possible from propane.
- Q: Can solar panels be installed on public parks or gardens?
- Yes, solar panels can be installed on public parks or gardens. In fact, it is becoming increasingly common to see solar panels integrated into the design of these spaces. Installing solar panels in public parks and gardens can help generate clean energy, reduce carbon emissions, and provide shade and shelter for visitors.
- Q: I jotted down some notes for my Technology and Architecture class and I'm trying to figure out what i meant when i said 'Treated with gases at extremely high temperatures.' I have NO idea what I was talking about :) Im trying to figure out if what I am talking about is about Silicon, Polychristaline, or a Solar Cell/Panel.
- Let’s start off and discuss the three main types of photovoltaic (PV) panels: Monocrystalline Solar Panels - Monocrystalline cells are cut from a block of silicon that has been grown from a single crystal.These tend to be the most efficient, but also the most expensive solar panels. They have been considered the go-to panels for the last couple decades, and also boast being the oldest and most dependable. Polycrystalline Solar Panels - Polycrystalline cells are cut from multifaceted silicon crystal. They don’t come from a single piece of silicon crystal, but rather from many different crystals. These solar panels tend to be less efficient than monocrystalline solar panels of the same size. This means a 200 Watt Monocrystalline panel will usually be smaller than a 200 Watt Polycrystalline panel. Thin Film or Amorphous Solar Panels - These panels are not made up of any crystals. They are actually a thin layer of silicon deposited on a substrate or base material like metal or glass. Thin film solar panels tend to be the least efficient per square foot, but they are also the cheapest. The best application for amorphous panels is if you have a large amount of surface area and space doesn’t matter.
- Q: How do solar panels affect the overall comfort of a building?
- Solar panels can positively impact the overall comfort of a building by reducing energy costs and improving indoor temperature control. They generate clean and renewable electricity, which can power various systems such as heating, ventilation, and air conditioning (HVAC) units. This helps to regulate the indoor temperature more efficiently, leading to a more comfortable environment for occupants. Moreover, solar panels can also reduce reliance on the grid, ensuring a more reliable energy supply and enhancing the comfort and stability of the building.
- Q: Can solar panels be installed on carports or pergolas?
- Yes, solar panels can be installed on carports or pergolas. These structures provide ample space for installing solar panels, allowing them to generate clean and renewable energy while also providing shade and protection for vehicles or outdoor spaces.
- Q: Can solar panels withstand extreme weather conditions?
- Yes, solar panels are designed to withstand extreme weather conditions. They are built to be durable and can withstand hail, heavy rains, high winds, and even snow loads. Additionally, they are made with materials that can resist corrosion and damage from prolonged exposure to sunlight.
- Q: I want to know that, is there any thing likehow much charge we can get per square feet. in a solar panel.let me know.also, I will appreciate if reference are given.
- I found some 0 square ft. solar panels that produce 30 watts . 3 watts per s.f. . A 2,000 s.f. home would consume around 2,000 kilowatt hours of electricity in summer months in areas that require air conditioning . This would require 67 kwh daily . You would need ,000 s.f. of panels and dozens of batteries to store the energy for night time .
- Q: How do solar panels perform in areas with high pollution levels?
- Solar panels can still perform well in areas with high pollution levels, but their efficiency may be slightly reduced. Air pollution can cause a build-up of dirt, dust, and particulate matter on the surface of the solar panels, which can decrease their ability to capture sunlight. Regular cleaning and maintenance can help mitigate this impact and ensure optimal performance. Additionally, advancements in solar panel technology, such as anti-reflective coatings and self-cleaning mechanisms, are being developed to address the specific challenges posed by pollution.
- Q: How many solar panels do you need on your house to power your heater in winter?
- You can get over 5 times the efficiency at lower cost by directly absorbing the heat in a solar water-heating collector. Use the electrical panels for making electricity for stuff that needs it.
- Q: planning to get one, for a store/house, we use alot of electricity at least 500-3000 dollars a month. how much money would this save us? how big would we have to get the solar panel?[aproximately]
- There are a lot of factors to consider. Net metering, utility rates, number of hours of daylight, size and orientation of roof or other location. I can tell you I had a 3.74 kwhdc system which reduces my bill by about $200 a month. It cost $26K installed, I received a $0K rebate from my utility and a $2K federal tax credit. Businesses have always been able to get a 30% fed. tax credit, this year everyone gets it. If this is a business you plan on owning for a long time there is no reason why you can't do the install in stages. Of course making sure you are conserving as much energy as possible will also help. Using energy efficient lighting, appliances and electronics, Turning off lights, monitors, computers, printers etc when people go home, sharing printers and other resources, adjusting the thermostat and using natural light can all help reduce your electricity usage.
