- Q: Hello, I have been trying to go green, I Have purchase somesolar panel they are about 45watts I been putting it against my window and getting ok power out of it enough for my lights and a couple of low watts gadget (cellphone, 2v light, portable dvd) for couple of hours.But its seem to drain the 2v faster then I can charge Am I getting the most power out of my panel?Or should I place it on the roof? I'm in Texas and it gets hot and sunny the sun beam my room windows pretty good during 4pm-6pm.
- outside is going to be much better. You can't tell but glass is actully opaque to many ranges of 'light'. If you look at advertising for windows you may see claims to reduce sun fading of your carpet/ furniture. That is because the glass blocks UV. Solar panels get some of their energy from UV light. Also some windows are engineered to block IR to help insulate better when the house is cooler than the outside. Again, solar panels get some of their energy from light in the infrared range. And finally if you're charging batteries the 'off angle time' is still important. The amount of light absorbed is pretty closely related to the cosine of the angle that the sun is 'off' of the direct. so when the sun is 45 degrees off of perpendicular the panels still get cos45 =.707 or about 70% of the available energy. (In practice it's a little less than that because not as much energy gets to the panel to be absorbed as at midday). But anyway, you can figure two hours of morning or late afternoon sun will give you as much energy as hour of midday sun. So if the panel is inside, you miss out on that available energy.
- Q: How do solar panels affect the property's green certification?
- Solar panels can positively impact a property's green certification by enhancing its sustainability and energy efficiency. The installation of solar panels reduces reliance on non-renewable energy sources, decreases carbon emissions, and promotes the use of clean energy. This aligns with the requirements of most green certification programs, which prioritize environmental responsibility and conservation. Therefore, incorporating solar panels can contribute significantly to a property's green certification and help demonstrate its commitment to sustainable practices.
- Q: Can you please tell me how much a solar panel costs?Please back up your info with a website.
- If okorder /.. Low-cost crystalline panel manufacturers such as Suntech are believed to have costs in the $.50/watt range today - making it $300 for a 200-watt panel. That doesn't mean that one can buy a panel for that price, of course. If you mean a DIY panel from purchased solar cells, the cost would be closer to $360 for an equivalent-powered panel, not counting the price of the frame, and the labor. A homebuilt panel would not stand up to decades of weather unless one spent even more on the frame. And since such a panel would not have safety certification, it could not legally be connected to the grid in most places. If you meant a water heating panel, please update or post another question - I'm sure people will chime in.
- 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?
- Be aware that you cannot discharge the full capacity of a lead-acid battery without destroying the battery. With a normal battery of this type, you would only want to discharge about 20%, so you would need a 70 AH battery bank. For the 3-day requirement, 500 AH. This is still within reason. If you didn't have the 3-day requirement, you might consider going with NiMH batteries. Back to the 500 AH bank, you would usually charge at at least 5% C, or 25 amps. At the 5 volts that you need for charging, this is 375 watts. Possibly you could go as low as 200 watts.
- Q: Are solar panels recyclable?
- Yes, solar panels are recyclable.
- Q: I am looking at a need of roughly 30w/hour need per 24 hour period. I have spent several hours now looking for information online and have found plenty of info regarding the panels themselves, but information regarding the batteries backups have been slim. I understand that there is a 5-7 hour peak time to collect the energy. I am looking for information regarding the batteries themselves. How do the batteries work, what size batteries should I look for, and what is the life expectency for the batteries? Any website links would also be appreciated!
- First, you didn't say the voltage. Second, 30 W/hour per day. Third, battery backup capacity in Ah = Ampere hour. For 2 Volt DC here's the calculations : 30 w/hour means = 0.83 or rounded Ampere hour. You know peak time 5-7 hour (let say 6 hour)charging time (collect the sun energy). Ampere hour per day (24 hour), with 20 Ah Battery backup is OK. And the Solar Panel is 3 Ampere charging capacity minimal = 3 Amp x 6 hour = 8 Amp hour.
- Q: How do solar panels affect roof weight load?
- Solar panels can increase the weight load on a roof, but their impact is generally minimal. The weight of solar panels is usually evenly distributed across the roof surface, and most roofs are designed to handle this additional load without any issues. However, it is recommended to consult with a professional to assess the roof's structural integrity and ensure it can support the added weight of solar panels.
- Q: I purchased some small 3.6 v 70mA solar panels online. I have no experience with solar panels. I am confident of the layout of the parallel circuit I want to create, however I don't know how to properly connect the tabs that come from the sides of the panels. Any help on connecting them?
- Each solar panel will be wired to each other in parallel if you have more then one. When you wire in parallel the amps(current) from each panel will add to the total sum of current, but the total voltage stays the same. The voltage must match the rest of your system. For example, if your are using 2 volt solar panels you must be using 2 volt batteries and voltage regulator. Voltage regulator must be rated above maximum voltage and current(amps). Connect the output from the solar panels to a properly rated regulator, solar panel voltage regulators are rated by maximum voltage and amps, that will shut off the current flow to the batteries once the batteries are sufficiently charged there by preventing damage to the batteries. The way that you figure the rating needed for the regulator is by adding the maximum amps for each solar panel, this should be listed on the solar panel, and if they are 2 volt panels and they are connected in parallel then max voltage should be around 22 volts. It's the amperes that is most importance when choosing a regulator
- Q: Are there any risks of fire associated with solar panels?
- Yes, there are some risks of fire associated with solar panels. While solar panels themselves do not combust, there have been instances where electrical malfunctions, such as faulty wiring or improper installation, have led to fires. Additionally, if a fire breaks out in the vicinity of solar panels, it can be more challenging for firefighters to extinguish due to the electric current flowing through the panels. However, when installed and maintained properly, the risks of fire are relatively low.
- Q: How do you know when it is a good deal to buy a solar panel. For example, what is a good cost per watt, how many volts should I expect, etc.
- Both might be bigger. When it is cloudy and little solar (iciness) you'll have a breeze. When it is nonetheless and sunny, you could have the solar. When the batteries are charged, extra vigour from the windmill can also be shunted right into a resistance heater in a water tank, preheating home water, decreasing that price. Downside of windmills: There is a few noise. you do desire a tower of a few form to get above treeline. It's mechanical, so it's going to want periodic renovation and would possibly holiday, or will put on out, or be broken in a windstorm. Panels will final for many years, simply have to be wiped clean of snow within the iciness, and washed off, in case you are living in a dusty subject. They are hard, however the glass can also be damaged.
