Product description
A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.[2] It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.
he photovoltaic effect was experimentally demonstrated first by French physicist Edmond Becquerel. In 1839, at age 19, he built the world's first photovoltaic cell in his father's laboratory. Willoughby Smith first described the "Effect of Light on Selenium during the passage of an Electric Current" in a 20 February 1873 issue of Nature. In 1883 Charles Fritts built the first solid state photovoltaic cell by coating the semiconductor selenium with a thin layer of gold to form the junctions; the device was only around 1% efficient.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: During the summer my house uses about .47 kw/h I am wondering what solar panel do I need to cover most or all the electric bill. A link would be helpful too :)
- If okorder If you have a fair chunk of money to drop on a standing seam steel roof, check out who Powerfilm has as their preferred installers for their roofing panels.
- Q: when solar panels have served their purpose, what is done with them?

- Q: Can solar panels be installed on a boat or yacht?
- Yes, solar panels can be installed on a boat or yacht. Many boat and yacht owners opt to install solar panels to harness the sun's energy and power their electrical systems on board. These panels are typically mounted on the boat's roof or deck, and can provide a sustainable and renewable source of power for various applications while out on the water.
- Q: Can solar panels power an entire home?
- Yes, solar panels can power an entire home. By harnessing the energy from the sun, solar panels can generate electricity to meet the energy needs of a household. The number of solar panels required depends on factors such as the home's energy consumption, sun exposure, and panel efficiency. With proper installation and sizing, solar panels can effectively provide power for all the electrical needs of a home, including lighting, appliances, and heating/cooling systems.
- Q: Can solar panels be used in remote areas without access to the grid?
- Yes, solar panels can be used in remote areas without access to the grid. Solar panels generate electricity by capturing sunlight and converting it into usable energy. This renewable energy source is particularly useful in off-grid locations as it provides a sustainable and independent power supply. With advancements in solar technology and the availability of battery storage systems, solar panels can effectively meet the energy needs of remote areas, even during nighttime or periods of low sunlight. This makes solar panels an ideal solution for powering homes, businesses, and infrastructure in remote locations without grid connectivity.
- Q: What is the difference between on-grid and off-grid solar systems?
- The main difference between on-grid and off-grid solar systems is how they are connected to the power grid. On-grid solar systems are connected to the local utility grid, allowing excess electricity generated by the solar panels to be fed back into the grid and credited to the homeowner. This means that on-grid systems rely on the grid for power during times when the sun is not shining, such as at night or during cloudy days. On the other hand, off-grid solar systems are not connected to the power grid and operate independently. These systems typically use batteries to store excess electricity generated during the day for use during periods of low or no sunlight. Off-grid systems are commonly used in remote areas where connecting to the grid is not feasible or cost-effective. Overall, the distinction lies in the connection to the power grid and the reliance on it for electricity supply.
- Q: I am starting to think about solar panels as an option for my home. I have done some research on panels, to be honest its all very confusing. There are many different panels some with 60 watts some all the way up to 20 watts. My household currently uses about 2700 to 3400 kWh every two months. So based off of my power usage maybe you can answer some of the following questions:What kind of panels should I be looking at?Which panel manufacturers give the best bang for the buck (reliable/affordable)?Anything else I should be concerned about?I am just starting out in educating myself on solar power so please excuse me if I sound very naive. Any information that you may have will be helpful. Thanks in advance.
- I'm not an expert, but I recently went through the process and now have a system on my home. I got 3 quotes from 3 licensed contractors and they all seemed to be about the same, the prices seemed to be based on the amount of energy they produced. In CA and I'm sure everywhere else they are tested by an independent agency which rates the output of the panels. You seem to have similar usage as my house, I got a 3.75kwhdc unit, it isn't expected to eliminate my bill, but it should reduce it by quite a bit. I've only had it for a few months and it took me from about 45 kwh per day to around 0. I know I'll have lower output in the winter, but my usage is lower in the winter as well. I decided on this size unit to maximize my rebates and I can take advantage of my utilities rebates when I add to the system in a few years. The difference between panels seemed to be how big they were. Some systems can be twice the size and produce the same amount of energy. I put a couple links below that I found helpful. The roseville pv buy down program has some great links that give information about specific systems.
- Q: How do solar panels generate electricity?
- Solar panels generate electricity through the photovoltaic effect, where sunlight is converted into electricity. The panels consist of multiple solar cells made of semiconductor materials, typically silicon. When sunlight hits the cells, it excites the electrons, causing them to flow and generate an electric current. This current is then captured and used to power various devices or stored in batteries for later use.
- Q: What is the impact of roof shading on solar panels' efficiency?
- Roof shading has a significant impact on the efficiency of solar panels. When a roof is shaded, whether by nearby trees, buildings, or other obstructions, it reduces the amount of sunlight reaching the panels. This shading creates areas of lower or no sunlight, resulting in decreased energy production. Therefore, minimizing roof shading is crucial to maximize the efficiency and overall performance of solar panels.
- Q: are there solar panel that work without the sun?
- No. Solar panels require light to work. The closest type of passive energy collecting device is a thermocouple, which generates electricity via a temperature differential. But it requires a cold and hot source to operate, while a solar panel only requires light. Good luck!
