Q:when we say a solar panel has 20% efficiency, do we mean that it converts 20% of sunlight reaching it into electricity or that it converts 20% of visible light(which is only 7% of sunlight) into electricity?
Photo-voltaic solar cells use the visible light range (photons) for the conversion of sun's rays to electrical energy. The potential of solar radiation is ,353 Watts per square meter, but that is mostly a measure of heat, or infrared radiation. The visible light is actually a small portion of the spectrum. You have struck on a problem associated with photo-voltaic cells. Infrared radiation acts to heat up p-v cells (heat stress), causing them to be much less efficient. It would be interesting to see a hybrid p-v panel that is cooled with fluid or air running through it. This would increase efficiency of the p-v process while providing a heating source. This in turn could be used directly for heating or for production of electricity through a generator system.
Q:Can solar panels be installed on art installations or sculptures?
Yes, solar panels can be installed on art installations or sculptures. In fact, integrating solar panels into art installations and sculptures has become a popular trend in recent years. This allows for the creation of sustainable and eco-friendly artworks that can generate renewable energy. Additionally, the combination of solar panels and art offers an innovative way to raise awareness about renewable energy and environmental issues.
Q:Can solar panels be used for powering a hotel or hospitality establishment?
Yes, solar panels can definitely be used to power a hotel or hospitality establishment. Solar energy is a reliable and renewable source of power that can be harnessed to meet the energy demands of such establishments. By installing solar panels, hotels and hospitality establishments can not only reduce their carbon footprint but also save on electricity costs in the long run. Moreover, advancements in solar technology have made it possible to store excess energy and use it during non-sunlight hours, ensuring a consistent power supply for the establishment.
Q:How much sunlight is needed for solar panels to work?
Solar panels can work with any amount of sunlight, but they are most efficient when exposed to direct sunlight for at least 5-6 hours per day.
Q:Are there any health risks associated with solar panels?
There are no direct health risks associated with solar panels. However, improper installation or maintenance may pose electrical hazards, and exposure to high temperatures or falling from heights during installation can lead to accidents. Additionally, some solar panels contain small amounts of hazardous materials, but they are tightly sealed and the risk of exposure is minimal. Overall, when installed and maintained correctly, solar panels are safe and have numerous environmental and health benefits.
Q:Hello, i want to ask whether if you could make an improvised version of solar panel made from an old CD or DVD?Is it possible or not?Please give me steps on how to make one if you know(put aside the one you see on quot;ehow: How to Make a Solar Panel From CDswhich says a bit confusing for me :( )Why not?
A solar electric panel? No. Solar electric cells, or more properly photovoltiac (PV) cells, are made from specially prepared (doped) wafers of silicon, much like transistors and diodes. CDs and DVDs are made from plastic plated with aluminum. They don't have anything to do with each other. Of course you can make a reflector out of CDs or DVDs, and you could use a bunch of them to focus sunlight on a water tank or something - this is called solar thermal generation. (That's what that ehow page is talking about, not generating electricity.) But there are much better things to use for mirrors.
Q:I installed a 60watt solar panel on the top of my patio/pergola. This is wired to a charge controller then a battery in my basement. Do I need to run a ground from the solar panel? If so, whats the easiest way to do so? Is a wire attached to the aluminum frame then connected to a foot long rod into the ground enough?

Q:Can solar panels be installed on sloped roofs?
Yes, solar panels can be installed on sloped roofs. In fact, sloped roofs are one of the most common types of roofs where solar panels are installed. The angle of the roof can be adjusted to optimize the positioning of the solar panels and increase their efficiency.
Q:Thanks
Initial cost , space occupied AND DAILY CYCLE (unless through a battery) are the only disadvantages. REST ARE ALL ADVANTAGES
Q:I know the basics of how solar panels work. Solar panels convert sunlight into DC electricity which is stored in batteries which would need to be run through an inverter to convert it to household AC. But is there a way for the appliances to use the solar panels electricity FIRST and any additional power from the grid? Is that how it works or do they only run specific devices(water heater, pool pump, etc)?
Light striking a silicon semiconductor causes electrons to stream, making power. Sunlight based force producing frameworks exploit this property to change over daylight straightforwardly into electrical vitality. Sunlight based boards (likewise called sun powered modules?e prepare immediate current (DC), which experiences a force inverter to get rotating current (AC) — power that we can use in the home or office, in the same way as that supplied by an utility force organization. There are two sorts of sun powered force creating frameworks: matrix joined frameworks, which are associated with the business power framework; and stand-alone frameworks, which encourage power to an office for prompt use, or to a battery for capacity. Network joined frameworks are utilized for homes, open offices, for example, schools and healing facilities, and business offices, for example, work places and strip malls. Power produced throughout the daytime could be utilized immediately, and in a few cases surplus power might be sold to the utility force organization. In the event that the framework doesn't produce enough power, or produces none whatsoever (for instance, on an overcast or blustery day, or around evening time) power is acquired from the utility force organization. Power preparation levels and surplus offering might be weighed continuously on a screen, a compelling approach to gage day by day vitality utilization. Remain solitary frameworks are utilized as a part of a mixed bag of provisions, including crisis power supply and remote force where conventional foundation is distract
