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.

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:Can solar panels be installed on a fire station or emergency services building?
- Yes, solar panels can be installed on a fire station or emergency services building. In fact, many fire stations and emergency services buildings have embraced solar energy as a sustainable and cost-effective solution for their power needs. Solar panels can be installed on rooftops, parking lots, or open spaces surrounding these buildings to harness solar energy and generate electricity. This helps reduce their reliance on traditional energy sources, lowers operating costs, and contributes to a cleaner and greener environment.
- Q:If a solar panel has a power rate of 80 Watts and efficiency of lets say 30%. Does that mean the maximum power this solar panel can generate is (30/00)*80=54 Watts or its just 80 Watts?
- Solar panels are tested in a lab that has a light the produces 000 watt/hrs per square meter. In these conditions your panel will produce 80 watt/hrs. If you would like to know what it does in really world conditions you have to find the sun-hours in your given area. A sun-hour is basically how many watt/hrs hit a square meter in a day. This number changes based on time of year, orientation, and temperature. Here in Fairbanks Alaska if the panel was at 90 degrees facing true south in October (.9 sun-hours) It would produce 80 X .9 X .8 (20% efficiency loss due to wires and controllers) it would produce 273.6 watt/hrs on average each day.
- Q:I am currently building a house, iv designed it to be as self sustainable as possible, I'm in the process of installing solar panels but as I'm ordering online I was hoping someone here could tell me how many I would need to completely run a 5 bedroom home, just standard household appliances such as fridge and freezers, plasma tvs computers and of course lighting, various things like that, also I'll need power storage as well, some type of large rechargeable battery, any help would be great.
- You're missing a few assumptions: - where on the globe? - how well is your house insulated, how do you plan to heat/cool your house? - why do you insist on power wasting appliances like plasma screens? Usually, unless it's absolutely impossible, a grid-tie-in system is much better than an insular system. You could use the grid to 'store' electricity for those times when the sun isn't shining and as fall-back if your yield isn't quite as good as you calculated. With the battery system, you'll have to specify your reliability requirements. If you want a 00% guarantee that you'll always have electricity, even if the sun is not shining for a week longer than you've planned according to the past weather history of your area, you'll either have to ridiculously oversize your battery (and panel) system, or plan for some sort of backup system anyway. Finally, if you're really planing such a system, you might want to take a look at the fridges and freezers used on sailboats: these use a eutectic cold accumulator, i.e. you 'charge' the fridge when the engine is running (or the sun is shining) and it'll then keep the temperature for another ~2...35 (professional systems) hours.
- Q:How do solar panels affect the property's sustainable development goals?
- Solar panels can have a positive impact on a property's sustainable development goals by reducing the reliance on non-renewable energy sources and decreasing carbon emissions. They provide a clean and renewable energy source, contributing to the property's overall sustainability and helping to achieve goals related to energy efficiency and environmental conservation.
- Q:Do I need some type of regulator when the batteries are fully charged.?? The Arco Panels voltage is approx 7VDC at 2.5 amps, Should I limited the voltage to 4VDC???. I would like to connect both panels to up to five batteries at one time...???
- You can buy Solar Charger Regulators. I don't. These chargers limit the charging current to the batteries, so you do not get a full efficiency of the solar panel. They disconnect the batteries from the user side (the bulbs you use) if the battery voltage goes below a certain level (i.e. below 8V for a 2V battery), so you cannot use all the power available in the batteries, even in emergency. They introduce, at least, a 0.7V loss (diode forward voltage) between the panel and the battery. If you have SEVERAL panels and a lot of batteries, use a controller as above. If you only have one panel, insert a 5A trip fuse in line (in your case: twice the current of the panel), and a 0-20A diode in series between the panel and the batteries (Kathode side of the + of the battery, Anode side of the + of the panel). Install a voltmeter across the battery. The fuse will prevent any short or over-charge current. The diode will prevent the battery to discharge into the panel at night if it is not already protected. The voltmeter will allow you to watch the status. Your thought of limiting the voltage is useless: should the battery be low, the panel will drop its voltage, limited by the max current. Should the battery be fully charged and the solar panel at full efficiency, it will just try to charge the battery more. A bit of bubbles may result, hence the voltmeter to watch over it. If you want to limit the voltage to 4V, put a 4V Zener (4Vx2.5W!) in series with a resistor of, say, 7V-4V/2.5A or ~ Ohm, 5W, in parallel with the panel.
- Q:Are solar panels a good investment?
- Yes, solar panels are a good investment for several reasons. Firstly, they can significantly reduce or eliminate your electricity bills, resulting in long-term cost savings. Additionally, solar panels are environmentally friendly as they harness clean and renewable energy, reducing your carbon footprint. Furthermore, government incentives and tax credits are often available, making solar panel installation more affordable. Lastly, solar panels can increase the value of your property, providing a return on investment if you decide to sell in the future.

- Q:I need a new roof soon and I was wondering what the difference in cost would be from a standard shingle roof to a roof including solar panels. Does anyone know the cost difference?
- The solar panels are very expensive to provide much power. If u go that way do not skimp on the support as a high wind will blow them away. In Ecuador I put in a remote site for communications. It was working good when a Strong wind blew $0.000 worth of solar panels all over the jungle.
- Q:I want to buy a solar panel to charge deep cycle batteries and charge electronics off the DCB. I don't know how to wire everything up though or what materials ill need. Inverter? Gauge of the wire? Ampmeter?
- It does not matter if you father is a electrician he must be a fully qualified solar installer or you will not receive any money from the government. You need more than just solar panels you need regulators, grid interaction devices and array controller. 5KW installation is large and will cost around $5000 for the panels then around 5000 for controllers and equipment needed and then there are the basic materials such as rails, junctions, cables etc Total cost is approx $5,000
- Q:I mean like bread is made of wheat, what are solar panels made up of?How are they manufactured?
- Solar panels (aka photovoltaic panel) are most often made up of thin wafers of crystalline silicon or cadmium telluride. As photons from the sun enter the photovoltaic cell, electrons are freed from the substrate when are then collected by wires that run throughout the panel. And as we know electrons=electricity!
