Solar panel working process
In addition to being the ultimate source of all life on earth, the sun is an infinitely renewable, completely pollution-free source of electricity. Instead of burning fossil fuels dug up from the ground in a big power plant – a very 19th century, industrial age approach, when you think about it – solar panels convert sunlight directly into electricity, with no harmful emissions.
The basic unit of a solar panel is a solar cell, which usually consists of one or two layers of silicon-based semiconductor wafers. When struck by the photons in sunlight, the solar cell generates an electrical charge due to the "photovoltaic effect" – which is a pretty good name, since it produces voltage from photons. The flow of these electrons moves in a steady electrical current from one side of the cell to the other.
Dozens of these PV cells are packaged together into solar modules, which in turn are packaged into solar panels that are mounted on a rooftop and arranged to maximize their hours of exposure to direct sunlight. Because the electricity generated by all those solar cells is direct current (DC), it is then sent to an inverter that transforms the power into the same alternating current (AC) used by the appliances in your home and the local utility electricity distribution grid. Increasingly, these inverters are getting "smart," providing data monitoring for solar installation performance and other grid integration services.

- Q:How do solar panels affect the property's energy management strategy?
- Solar panels can have a significant impact on a property's energy management strategy. By harnessing the sun's energy, solar panels generate clean and renewable electricity, reducing the property's dependence on traditional power sources. This can lead to lower energy costs, increased energy independence, and a reduced carbon footprint. Solar panels also provide a stable and reliable source of energy, allowing for better energy planning and management. Additionally, excess energy generated by solar panels can be stored or sold back to the grid, providing additional financial benefits. Overall, solar panels play a crucial role in shaping and optimizing a property's energy management strategy.
- Q:im aware i dont fully understand. but with what i do. if P = iv, and current changes with voltage, whats the point of changing either. if in any cicumstance, you end up with the same wattage, how does changing either effect a solar setup. (2v panel vs 24v)thanks in advance. explain in laymans if you can.
- The choice of solar panel voltage comes down more to what the panels will be connected to. You're right that power can remain the same at the different voltages. Higher input (panel) voltages are sometimes used in inverter systems to reduce the effect of voltage draw-down. 2v panels (about 20v open circuit) work well for charging 2v batteries, connected in parallel, through a charge controller. For use of a grid-tie inverter, higher input voltages are sometimes used to reduce the effects of draw-down. You want to select and wire (parallel vs. series) your panels based on the input voltage requirement of the load, whatever it may be.
- Q:Can solar panels be used on a backpack or portable device?
- Yes, solar panels can be used on a backpack or portable device. These panels, often referred to as portable or foldable solar panels, can be easily attached to a backpack or other portable devices to harness sunlight and convert it into usable electricity. This allows you to charge your electronic devices while on the go, making them ideal for outdoor activities, camping trips, or situations where access to a power source is limited.
- Q:How much space is required to install solar panels?
- The space required to install solar panels depends on the size and capacity of the panels. On average, a solar panel installation for a typical household requires about 100-400 square feet of roof space. However, ground-mounted solar panels can be installed in larger areas, ranging from a few hundred square feet to acres, depending on the energy needs and available land.
- Q:What is the efficiency of solar panels?
- The efficiency of solar panels refers to the amount of sunlight that is converted into usable electricity. It is typically measured as a percentage and can vary depending on factors such as the quality of the panels and the location of installation. On average, modern solar panels have an efficiency range of 15% to 20%, with some advanced models reaching up to 25%.
- Q:Didnt solar panels use to cost around $250,000 5 years ago?
- I okorder to register for free and lock in long term costs. The increasing demand and competition is helping reduce costs.
- Q:If this was sold back to the grids what would be the profit i would stand to make per day on energy received in these panels? How did you come up with this answer?
- This question is too generalized to answer. Are you australia? If so ergon buys the power back at 45cents a KWH which is 3 times what they sell it for.(this is guaranteed for 20years) We have a 2.4kw system and it will take approx 5years to pay itself off. Once carbon trading is in full swing electricity costs are going to go up by 40%, then obviously it will take approx half the time.
- Q:Solar Panels not working very well, they have faded. Is there any paint or anything else I can do to restore them? Thanks Eileen
- Unfortunately Eileen the panels are bound to fade as its par for the course. Over time much like everything else (from an AC condenser to your knees and hips) everything starts to go south. When did you purchase and install your panels? If this was done within the past few years then something is definitely wrong, and you should have the manufacturer and installer come back and replace the panels....on their dime of course. Is the warranty on your panels still in effect? If so then its definitely something that they have to come back and take care of. There is a company I know of called Sun Electronics that has a 20 year warranty on their products, so if its worth anything you might want to buy your new panels/system from them. The panels around today are more efficient than those of years past, and with the cost coming down due to economies of scale and the tax incentives you might want to consider getting a new system. Sorry to let you down though Eileen!
- Q:Can solar panels be damaged by hail or extreme weather?
- Yes, solar panels can be damaged by hail or extreme weather. Hail stones can cause cracks or dents in the panels, compromising their efficiency and potentially leading to water leakage. Additionally, extreme weather conditions such as hurricanes or strong winds can dislodge or break the panels, causing significant damage. It is important to consider the durability and quality of solar panels when installing them in areas prone to such weather events.
- Q:can a small solar panel be charged with lamps?
- That would depend on the frequency that the solar panel accepts and the frequency of light that your lamp gives out. It may or may not work. The sun gives out a much broader spectrum of light, which is why solar panels are much more effective in sunlight. I have seen solar panels charged by lamps, but it usually doesn't work that well and I have never seen it work with fluorescent lighting.
