Product Description:
1. Structure of Polycrystalline Silicon Solar Panel Type CR290P-CR250P
Solar modules, which are widely used in ground mounted utility-scale PV plants, large-scale and small civil and commercial power generating system such as BIPV combined to the grid, roof-mounted PV power system, rural electrification, communications, emergency auxiliary power.
Solar PV module is comprised of some solar cells which are connected in serial with high efficiency and enhanced reliability.
PERFORMANCE
- High effi ciency, multicrystalline silicon solar cells with high transmission and textured glass deliver a module effi ciency of up to 16.0%,
minimizing installation costs and maximizing the kWh output of your system per unit area.
- Tight positive power tolerance of 0W to +5W ensures you receive modules at or above nameplate power and contributes to minimizing
module mismatch losses leading to improved system yield.
- Q: Why might energy from the solar panels sometimes be near zero even in the summer?
- Hey Cosmic, forget about Wayfare and Jenny here, but I have to say your question is a bit vague. When you say the panels produce near zero, how near? Are you using a watt meter, ammeter, or some other sort of metering device. Solar electric, or photovoltiac panels are made almost entirely of silicone wafers. Same as computer chips, when they get hot, the resist the flow of electrons. This is why most panel manufacturers advise installers to upgauge wiring if the temperature falls below 40 degrees F (5C) regularly. Below 0 C, you have to upgauge 2 wire sizes. A good quality panel will put out 50% of its rated power in very cold climates, so it stands to reason that they will put out substantially less in hot weather. Many people think places like the SW United States is great for solar because it's always sunny. In Las Vegas for example, they have 27 sunny days a month, and in August, the temperature frequently reaches 50 degrees C (20F) so people with photovoltiac panels are not even getting half their rated power on a good day. I'm not sure this is what you are asking about. Our home has been powered by the wind and sun for 2 years now. In the summer in the upper midwest, the days are warmer of course, but also much longer than in the winter. So our batteries will frequently fill up by 2:00pm, and the charge controller will taper off the solar charging the rest of the day to minimize overcharging. If you were to check the meters at 3pm, you might notice only 3 or 4 amps coming in when the array is rated at 42. This is normal for us in July and August. These are some reason why a solar array produces near zero in the summertime. Take care Cosmic, Rudydoo
- Q: How do solar panels affect the power grid?
- Solar panels can have both positive and negative impacts on the power grid. On the positive side, solar panels generate clean and renewable energy, reducing the reliance on fossil fuels and decreasing greenhouse gas emissions. They can also help to decentralize the power grid by producing electricity closer to where it is consumed, reducing transmission losses. However, the intermittent nature of solar power can pose challenges to grid stability and reliability, as energy generation fluctuates with weather conditions. Additionally, the excess electricity generated by solar panels at certain times can strain the grid if not properly managed. Overall, while solar panels offer significant environmental benefits, their integration into the power grid requires careful planning and management.
- Q: we are doing a fundraiser to have students pledge to make donations for a solar panel instalation on one of the school buildings. I am looking for a slogan for the campain.
- nasa solar panels seem to be better than silica / silicone (i forgot the exact chemical) they make them with ink and aluminum then case them in glass, they are supposed to last like 30 years or something. good stuff. anyway a SLOGAN: solar pannels save money, and over the long run allow the school to save tht momney or use it somewhere else in the school, ie better food, better seats, better computers, whtever. maybe you can relate the campain slogan to what the savings will be used for. maybe a new scince program thats funded solely on the savings of the panels. but ok a slogan: IT'S OBSCEEEENCE, ROTFL... GIVE SOME DOLLAR$$ AND GO GREEEEEN!!!!!! eh, i know not so hot, gimme a minuet. lol LET'S MAKE THIS PANEL HAP'N CAP'N... MIB! LMAO THE SUN, FREE FUN, COME ON AT LEAST GIVE ONE (place pic of dollar bill below the ONE) good luck.
- Q: Also, what's the solar panel's rate of producing electricity?
- Solar panels really can't compete with fossil fuels of any kind. They're great for low power consumption applications, but I doubt we'll ever see solar powered steel refineries or heavy manufacturing plants. A solar panel that produces 75 watts is about 62 x 33 (5 feet by almost 3 feet). 75 watts is enough to power a couple light bulbs; you'd certainly never cook anything on it. On the other hand consider how much heat and light is produced by a small natural gas fireplace or stove burner. It would take a lot of those 5 foot long solar panels to equal that.
- Q: how much energy does a kilowatt solar panel produce in a year? (average)
- You would be amazed how often I have answered this question. The answer is that it depends on your latitude and local weather . Let's see if I can give you enough information so that you can determine the answer for yourself. A kW solar panel is rated at kW when it is exposed to a solar flux of kW/m^2 (called a peak sun hour). There are readily available tables of effective peak sun hours per day by city (see Reference ). Let's use Fairbanks, AK as an example (it is the first line of the table). Fairbanks get an average of 3.99 of peak sun hours per day on average. So your panel would produce 3.99 kW*hr per day on average.
- Q: Has anyone actually used those kits online like energy4green or earth4energy to build their own solar panels or windmills? I'm so tempted but with my budget can't afford to waste any money. They have a 60 day money back policy but that doesn't include the money used to buy the supplies to try and build the things. My electric bill is almost $300 a month due to my stay at home disabled veteran husband who went from Utah snow to Florida sun and he has to have the AC on really cold. If anyone has actually built one can you tell me of your experience and if it actually is worth the money? I do lots of D.I.Y. projects but am a novice with electric besides installing a ceiling fan and changing out a light switch.
- What I've heard, is that for those sites implying that you can power your house and save money with homemade solar panels, is that if you try to get your money back, there is no response. Maybe if you used a real credit card, you could dispute the charges through your credit card company. Actually, I wouldn't be worried about buying materials and it not working - the more likely scenario is that you would get their instructions, and realize that they're practically worthless. In Florida, you have a chance to save money on your electric long-term, but it will be by investing maybe $0-20k, and then getting that back after 0 or more years. I'd suggest you contact a local solar installer and get a bid, even if it's only to scope out how much it would cost up front. Then you can shop around and see if you could save by installing it yourself. It's a serious project, not to be taken lightly. It took me about 3 months to put it up. It's possible that you will not save money by self-installing, as professionals may get better prices on the panels. The Florida state rebate is subject to availability of funds, and typically, I've heard people wait a long time to get it. The Federal rebate is a credit to your taxes, so you get it the next year.
- Q: how big of an solar panel do i need to power/charge my laptop?would one from canadian tire sell the right one?
- Yes. Basically, here's what you need (I'm keeping this general on purpose): The panels themselves -- how large an area depends on average power consumption and how much power you can get on average. That, in turn , depends on climate. You'd need more in Seattle than Tuscon, for example. I'd guess something in the neighborhod of 0 square feet. Depends also on haow many gadgets (printers, etc.) you have. You'll need a power storage system. Lithium gives you the best poser density (of off-the-shelf stuff) but an ordinary car battery works well and is reliable. And, of course, a control system to manage the power generation/storage/use so everything works together without that annoying smell that tells you you just cooked a few hundred bucks worth of equuipment! :)
- Q: I was trying to look online for solar panels for my home to take some of the strain off of using oil and electricity but I find it very hard to understand exactly how they are used.Like one that I looked up is 00 watts.....is that like a light bulb watt? How many things can that power? Is it really cheaper in the long run because the panels are very expensive?If anyone has web sites that can explain this to me I would appreciate a link, or anyone to answer part of my question.

- Q: Can solar panels be used in areas with limited space?
- Yes, solar panels can be used in areas with limited space. There are various types of solar panels available, including smaller and more compact designs that can be installed in tight spaces such as rooftops, balconies, or even on the sides of buildings. Additionally, solar panel technologies are continuously evolving, allowing for improved efficiency and the ability to generate more power from a smaller surface area.
- Q: What sort of maintenance is required for solar panels....?
- All panels should be cleaned to function best. Brush or wash off dirt and leaves. They should be checked for structural integrity and lack of rust. Solar Thermal panels should be checked for signs of leaks and/or discharge from pressure relief valves. Solar Photovoltaic should be checked for electrical function and grounding.
