Product description


60 cell multi-crystalline solar module. 40mm natural anodised frame. IP65 rated Jbox, 1m solar cable and a pair of MC4 connectors.TÜV SÜD,SABS ISO 9001:2008 certified.

Nominal voltage refers to the voltage of the battery that the module is best suited to charge; this is a leftover term from the days when solar modules were only used to charge batteries. The actual voltage output of the module changes as lighting, temperature and load conditions change, so there is never one specific voltage at which the module operates. Nominal voltage allows users, at a glance, to make sure the module is compatible with a given system.

Open circuit voltage or VOC is the maximum voltage that the module can produce when not connected to an electrical circuit or system. VOC can be measured with a meter directly on an illuminated module's terminals or on its disconnected cable.

The largest challenge of photovoltaic technology is the efficiencies of such solar systems. While utilizing such systems draws a great interest due to the long term returns of profit, the efficacy needs to come a long way before making it plausible to be introduced in all consumers of electricity.

Product feather

solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.

A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricityin commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Q: Are solar panels durable?
Yes, solar panels are durable. They are designed to withstand various weather conditions, including hail, snow, and strong winds. Additionally, most solar panels come with warranties that guarantee their performance for 25 to 30 years, indicating their long-lasting durability.
Q: What things can a solar panel power?
What things can moving water power? It just depends on the size and number of panels.
Q: i attached a usb charger to my solar panel(it has an output of about .2 volts) but i read on my multimeter its only using about 8 volts however on the conventional wall charger that i use to charge it has an output of about 5. volts.... i believe that my mp3 player is not charging it does not display the charging icon when it is on or off ....is this becuase the output is higher ? do i need to install a volt dropping diode to prevent it from putting to much energy at once? (my mp3 charges fine on the wall charger but does not seem to respond to the solar panel so it the circuits are fine....)
5.3V is the open voltage or? So the full wattage of the photograph voltaic panel is 45W or so? i assume you are able to no longer make all your small A/C home equipment into DC ones. so which you would be able to think of bearing directly to the 2V DC enter 00W inverter. this type of inverter might have a some bit extensive enter voltage variety from like V-20V some situations.
Q: Can solar panels be used in areas with frequent power outages?
Yes, solar panels can be used in areas with frequent power outages. Solar panels generate electricity from sunlight, which means they can continue to produce power even when the main grid is down. However, for uninterrupted power supply during outages, it is important to have an energy storage system, such as batteries, to store excess energy generated during the day for use at night or during power outages.
Q: So I want to power one of my car fans with some solar panels. I ordered quite a few and I want to power one of my fans under the hood. I've already disconnected the fan and pulled it out of the car to test it later.What all do I need besides the panels, fan, and wiring to make this work. This fan will not be tied to any other system. Currently, the fan is not operated by the car or any system of the car due to a modification made to the automobile allowing me to disconnect it from use months ago.Using the fan powered from the solar panels would help with the modification to increase air flow and speed into the area.Could someone please help me by telling me what else I need to make the fan operational from here?
You may not like it, but the answer's still the same. A car fan will draw anything from a few to several hundred watts, depending on which fan you're talking about (A/C, ventilation, cooling). A solar array will take up roughly one square meter to generate 00 Watts with the sun shining straight down onto it, so you'll need to cover (more or less) the entire roof (or hood) with solar cells in order to power that fan (minimum). If you still want to go ahead: Solar panels, Fuse, cables. Preferrably one cut-out diode per panel (in addition to the hopefully present internal diodes in the panels) in order to prevent one panle dumping its load into the next instead of into the fan. Much better option: get a low power fan (e.g a slow running computer fan) and connect it to that panel of yours. These fans make do with about 0 Watts (at a much lower air throughput), so you'll actually have a chance of running it from the solar panel without coverig your car in panels.
Q: I have a home made 24 volt electric cart. It is powered by two 2Volt deep cycle batteries. Since the motor runs on 24 volts the batteries are wired in series to produce the 24 volts. I only have a 2 volt battery charger, but I also have two 2 volt solar panels. It is a pain having to unhook wires, rewire it, or charge them one at the time.HERE IS THE QUESTION REALLY... Can I wire the two 2 volt solar panels together in series (ie: negative to positive) then connect it to the existing 24 volt system and have it charge the batteries fine. I know basic wiring, but I know nearly nothing about solar panels, will it work fine? will it cause them to break? or short out?(additional info, the solar panels are only rated at 5 amps so it will not overcharge the batteries or anything)
If the panels are the same, there is no problem in putting them in series. If you examine the panels, they will be made up of about 36 identical cells in series. Ok, now you have 72 cells in series, fine if they are the same. You need (at a minimum) a diode in the line so that when it is dark, the panels do not draw current out the batteries (it wont be much but you might as well block it). You say the panels are rated 5 amps? Those are pretty good sized panels! Unless you have a charging regulator, I guarantee that they Will overcharge the batteries (unless the batteries are huge, like the size of a refrigerator). Did you maybe mean 5 watts? About a foot square? If so, the output is about 300mA (0.3 amps) which will not overcharge a battery as long as it is at least as large as a garden tractor battery. At a 300mA charge rate, it will take a longgg time to recharge.
Q: Thinking about getting a solar panel installed but i'm worried about getting the govt. rebates. There is a Federal Tax credit and a State of Florida rebate and i'm wondering what the time frame is for getting the rebates. Has anyone gotten a solar panel installed recently that could give me more info.Thanks!
In case you hadn't heard the state is broke.
Q: i've heard environmentalists like ed begley jr use the phrase quot;peak shaving hourswhen talking about solar energy.what does that phrase mean, please?thank you to all who respond.
From a power company's perspective, it costs more to supply electricity during hours when electricity use is high. The times of day when power use is the highest are called peak hours. Historically power companies would sometimes charge large power users a higher rate during peak hours to encourage them to shift their electricity use to other times of the days. With the development of smart power meters and smart grid technology, it's now possible to offer the same incentive to individual home owners. so i'm wanting to eventually get solar panels.? If you live in an area where the electric rate varies depending on the time of day, then peak shaving improves your payback/return of investment on grid tied solar panels. Particularly in areas with high air conditioner usage, the peak hours generally correspond to the times when solar panels generate the maximum power. Look at it like this: Suppose your power company charges you $0.5/kWH during off peak hours and $0.30/kWH during peak hours. Because the solar panels generate the most power when the cost of electricity is the highest, it is easier to justify the cost of installing the panels because you are avoiding buying electricity at the highest rate. If your power company just bills you at a flat rate at all times, then it becomes more difficult to justify the cost of installing the panels and associated equipment..
Q: Hey was looking at a 5 watt 2 volt solar panel and was wondering if it'd be enough to power a regular light bulb. Also need to power a 5volt 6.5 amp pump for at most a minute at a time. So basically if I had this panel would I be able to plug a lamp into it and have it light for 5+ hours at a time with the possibility of running the pump? If not what size panel would I need?
NO ! Pump needs 747 watts power. And you need to buy one more expensive DC to AC converter to make it work. Use solar panel at least has 000W output.
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 catch fire, there have been incidents where electrical components, such as faulty wiring or inverters, have caused fires. However, the risk is relatively low and can be mitigated by proper installation, regular maintenance, and adherence to safety codes and standards.
