255W Poly Solar Panel for Solar System Grid Tied or Off Grid


Q: What is the difference b/w them which one is better .
these solar panels are named different based on the solar cells used... mono-crystalline solar cells: As the name suggests, each cell is made from a slice of a silicon crystal, which is made by purifying, melting and freezing silicon. pol-crystalline solar cells: these are a slight variation of single crystal solar cells. they are made of slices cut out of blocks of several silicon crystals, as opposed to single silicon crystals. check the link below to see other differences between the two types (easy to understand), such as their prices and efficiency levels. there is also a third type of solar cell/panel called amorphous solar cells.
Q: Ok so i can have a problem i have two 5 watt 2 volt solar panels a 2 volt battery and a 400 watt ac 2 volt dc inverter i believe im only getting 5 watts from from my solar panels thats the equivalent of one is there any way i could get full voltage from my solar panels without theoretically burning my wallet.. please help
I think you need to take some basic courses on electricity. Usually, 8 volt solar panels are required to charge 2 volt batteries. The voltages of photovoltaic cells are set by the material they are made of, only current changes. If you hook up a 2 V solar panel to a 2 V battery, no current will flow, nothing would get charged. You would need some elaborate DC to DC voltage converters to charge a 2 V battery from 2 V solar panels. Solar panels can be connected in parallel or in series, as you've made the mistake of buying 2 V solar panel, you would have to wire them in series and have a charge controller that could limit the voltage of the charge. Did it ever occur to you that two 5 watt solar panels would not be able to provide the power needed by a 400 watt inverter? You're just running off your battery with your set up. Solar power is expensive power, you can not have solar without burning a hole in your wallet.
Q: Does anybody know if there are any courses for solar panel installation, and/or what trades you need for this position?
In Europe the governments offer an electrical buy back incentive of surplus solar electricity but to claim the income the solar panels must be installed by a registered installer who submits details of their skills. The skill to install requires some experience in building/roofing work for which there is no qualification and an electrician to wire up the components to the mains. Electrical engineering courses are available at local tech colleges. If you are just installing a 2/24 volt system you don't really need much experience, it is not syncing a full mains voltage in to the domestic mains! Installing thermal [water] solar uses similar building skills and requires he final fix to be performed by a heating engineer, again the course is available at tech colleges. both plumbing and electrical engineers need to be updated on changes and so there is ongoing education costs and licenses. If you can't afford college [two year +] try finding an employer who will let you work and study part time. There is a lot of demand here so few employers pay for the course but some do. go through your yellow pages and submit your cv to electricians/plumbers. Then when you get qualified learn about solar, and set up your own business. As a builder of sorts! Ive fitted systems and then found a electrician/plumber to do the final fix. You cant beat experience.
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: Can solar panels be installed on residential complexes or apartment buildings?
Yes, solar panels can be installed on residential complexes or apartment buildings. Many residential complexes and apartment buildings have successfully installed solar panels to generate clean and renewable energy for their residents. This not only helps in reducing electricity bills but also contributes to a greener and more sustainable environment.
Q: what is needed beside the panels and do you need an electrician to hook it up
The main components for a solar electric system are the panels, racks for mounting the panels, and inverter to convert the panel's DC power to AC, which can be pumped into the grid if necessary. There would also be various electrical supplies involved - wire, conduit, possibly a switch and/or circuit breaker. On the paperwork side, there's a building permit, permission from the power company to connect, and some inspections. Although it could be done by a homeowner, it's not a trivial project, and the best way to get it set up is to contract a professional solar installer. They all give free quotes, and can explain your various options when they visit.
Q: Can solar panels be used to power a military base?
Yes, solar panels can be used to power a military base. By harnessing solar energy, military bases can reduce their dependency on traditional energy sources and enhance their operational capabilities. Solar panels can provide a reliable and sustainable source of electricity to power various facilities and equipment in a military base, contributing to energy independence and environmental sustainability.
Q: What is the role of inverters in solar panel systems?
The role of inverters in solar panel systems is to convert the direct current (DC) electricity produced by the solar panels into alternating current (AC) electricity, which is the type of electricity used in homes and businesses. Inverters also ensure that the AC electricity produced is synchronized with the grid, allowing for efficient utilization or storage of energy, and enabling solar panel systems to feed excess electricity back into the grid.
Q: I bought a pack of OEM mini solar panels that produce 4.2v and 22mA and I was just wondering how many LED's I could hook up to one mini solar panel? I currently have one green LED with a resistor on the one panel but was wondering how many I could possibly run off of one panel?
Typically LED's run off low voltage and 20mA or so of power (it depends what kind of led you have). That being said if one of your solar panels only provides 22mA of power then your circuit would have to be a series circuit for you to connect more than one. In a series circuit the current supplied of 22mA will go through each LED whereas a parallel circuit the current would be divided for each subsequential led. So in your case i can see you getting away with 3 or so led's before the voltage drop across each led will cause the voltage to be insufficient enough to drive anymore. Keep in mind the LED's will turn on but the first one will be bright then next one not as bright and so on. If you opted out and bought a solar panel with 200mA and 4V you could wire the led's in parallel and get 0 led's to turn on with the same brightness or intensity. Hoped that helped!
Q: My solar panel is 24long..It is set at 45deg..the arms are 8quot;long to achieve that angle for winter. I need to get to 7deg for summer..how long will the new arms need to be?..in layman's terms please...thx
