Solar Module Introduction

Solar Module is the core part of solar PV power systems, also is the highest value part of it. The function of Solar Module is to convert the sun's radiation to electrical energy, or transfer it to battery and store in it, or to drive the load running.
The Product has been widely used in space and ground, it mainly used for power generation systems, charging systems, road lighting and traffic signs areas. It could offer a wide range of power and voltage, and with high conversion efficiency, and long service life.

Solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available, based on thin-film cells. These early solar modules were first used in space in 1958.

Electrical connections are made in series to achieve a desired output voltage and/or in parallel to provide a desired current capability. The conducting wires that take the current off the modules may contain silver, copper or other non-magnetic conductive transition metals. The cells must be connected electrically to one another and to the rest of the system. Externally, popular terrestrial usage photovoltaic modules use MC3 (older) or MC4 connectors to facilitate easy weatherproof connections to the rest of the system.

Q:Is there such a thing as portable solar panels? Can these be obtained for say a mobile homes / caravans etc.: There are RV solar panels but they are mostly for extending the life of the batteries, you should still bring a generator. There are marine solar panels and wind turbines which are larger but many sailing yachts are larger too.

Q:I'm thinking of these solar panels that people have on their rooftops in domestic properties. I suppose I mean after how long do you break even with respect to just carrying on without them and getting you electricity from the utilities companies? Or answer in any way you think is pertinent. The more info the better.: The payback period for a solar PV installation is based upon the cost of the installation compared to the savings achieved. Therefore if you installed a modest set of panels yourself, did not need on site electrical storage and did not have any permitting fees but did enjoy rebates you would be doing better than if the installation costs were high, the solar equipment was expensive, you had to purchase storage batteries, it was costly to maintain and permitting was absurd. On the other side of the equation if your electrical use is high, you perhaps own an EV or you can sell power at a high rate then the costs you will be offsetting will be higher and the payback period will be lower. If your electrical use is minimal, there is no time of use metering available the payback period will be higher. Some of the costs you may be offsetting may not be electrical. If you concurrently purchased an EV then you may be offsetting the cost of gasoline which would be higher than electricity. Overall rebates and incentives play a major role. I have seen payback periods as low as 3 years claimed (commercial installation with special city tax breaks) and as long as over 20. A bell curve would probably find most of the installations in the 7 to 5 year category. A solar thermal installation (for hot water, heating and sometimes AC) is far more efficient and most would be in the range of 2 to 8 years.

Q:Can solar panels be used in areas with high pollution levels?: Yes, solar panels can be used in areas with high pollution levels. While pollution can potentially decrease the efficiency of solar panels, they can still generate electricity even in polluted environments. Additionally, using solar energy can help in reducing reliance on polluting fossil fuels, contributing to the overall improvement of air quality.

Q:Can solar panels be used in disaster relief efforts?: Yes, solar panels can be used in disaster relief efforts. They provide a reliable and sustainable source of electricity, allowing for the operation of critical equipment such as lights, phones, and medical devices. Solar panels can be quickly deployed in affected areas and can help reduce the reliance on fossil fuel-based generators, thereby reducing pollution and the need for fuel transportation.

Q:Can solar panels be installed on a parking lot or carport?: Yes, solar panels can be installed on a parking lot or carport. This type of installation is commonly known as solar carports. Solar carports provide shade for parked vehicles while generating clean and renewable energy. They are becoming increasingly popular as they offer dual benefits of generating electricity and providing shelter.

Q:Can solar panels be used on vehicles?: Yes, solar panels can be used on vehicles. Solar panels can be installed on vehicles such as cars, trucks, boats, and even bicycles to generate electricity from sunlight. This electricity can be used to power various components of the vehicle, such as the battery, lights, or even the motor in some cases. Solar panels on vehicles offer a sustainable and renewable energy source, reducing reliance on traditional fossil fuels and contributing to a greener and more eco-friendly transportation system.

Q:I am designing a solar panel but i need to have maximum power output.How can i optimize the equation for power Total power=voltage * current to get maximum power.: first place the panel so it is at right angles to the solar rays. Make sure none of the panel has any shade whatsoever. For best results use motor drives to keep it in that position as the sun moves across the sky. For overall maximum versus time, you need to be near the equator. Solar cells have a high internal resistance, so for maximum power transfer, you need a load of that same resistance. A good charge controller will use DC-DC converters to provide that load. .

Q:How do solar panels affect satellite dish reception?: Solar panels can potentially interfere with satellite dish reception if they obstruct the line of sight between the dish and the satellite. However, modern satellite technology and proper positioning of both the panels and the dish can often mitigate any negative impact on reception.

Q:If not how do they give power to a house/a company?: They are powered by the sun. You set them up out side of the house or on the roof and the sunlight shines on them through out the day. It stores the energy into light so when you turn on a light it is from the sun's energy. Plus it can save you on electric bills.

Q:I have some property off the grid and am looking to add solar power: Of okorder /... , and shop the web for the best panels for yourself. p.s. I'd avoid amorphous silicon panels. They may be cheap, but they'll go bad or seriously degrade in just a few years. p.p.s. I'd also avoid internet guides that claim you can make your own panels very cheaply, if you'll just pay them $$ for the information. Those guides don't live up to their advertising.
