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 used for powering a manufacturing facility?
- Yes, solar panels can be used to power a manufacturing facility. Solar energy can be converted into electricity, which can then be used to power various processes and equipment in a manufacturing facility. This can help reduce reliance on traditional energy sources and promote sustainability. However, the feasibility and capacity of solar power for a manufacturing facility would depend on factors such as the facility's energy requirements, available space for solar panel installation, and local sunlight conditions.
- Q: How do solar panels affect the resale value of a home?
- Solar panels can have a positive impact on the resale value of a home. Studies have shown that homes equipped with solar panels tend to sell faster and at a higher price compared to those without. This is mainly because solar panels offer potential buyers the benefit of reduced energy costs and a more sustainable lifestyle. Additionally, the presence of solar panels can enhance the overall appeal and desirability of a property in today's environmentally conscious market.
- Q: Thanks
- Initial cost , space occupied AND DAILY CYCLE (unless through a battery) are the only disadvantages. REST ARE ALL ADVANTAGES
- Q: Can solar panels be installed on a carport?
- Yes, solar panels can be installed on a carport. In fact, carports are a great location for solar panel installations as they provide ample space and a suitable structure to mount the panels. Installing solar panels on a carport can help generate clean and renewable energy while providing shade and protection for vehicles parked underneath.
- Q: Monocrystalline panels are sooo expensive! Thanks for reading.
- Since you are asking for a rather technical answer you should be aware that solar panels come in several varieties. Two broad categories are photovoltaic panels which have achieved marketable efficiencies of around 24% and solar thermal panels which are routinely achieving efficiencies of between 60 to 80% while they are also much cheaper than photovoltaic panels. So the short answer is solar thermal panels. But what can you do with solar thermal energy. The answer is just about everything you can do with light energy. Sometimes additional equipment makes the efficiency drop to near that of photovoltaic panels. The trick is to keep the devices as simple and as efficient as possible. Solar thermal can of course be used to heat our homes. But it can also be used directly for air conditioning. The type of air conditioner uses a slightly different principal but it is one of the oldest that was once used in ice houses before refrigerators. It is known as an absorption system. At some point you may want to make electricity from the sun's heat. The most efficient commercial systems are not photovoltaic but solar thermal. There are several commercial systems where increased scale improves efficiency. The most efficient is a solar parabolic dish system combined with a stirling engine. At around 30% efficiency it beats photovoltaic and other thermal systems. At this level of commercial development, the various systems are more often described as solar collectors rather than panels.
- Q: I found portable solar panels used for boats etc. and was wondering how I could effectly use them for my home instead. If you have used them in the past, please tell how they worked (good or bad).
- Most people think all one needs is some solar panels to make power. It doesn't usually work that way. On a boat it is easy because most boats use batteries and DC power. If all you want to do is make DC power, you will need a battery to hook your portable unit / units to. You can then use the battery to supply power to something that uses battery power. You may need a voltage converter if the device is not 2 volt. To use the power you get from solar panels for AC power like your house has, you need a regulator, inverter, and controller to change the DC output from the panel (s) to AC and then control the power into your electric system. You also need a unit from your electric company installed. A decent minimal solar system for an average house may cost around $5000 - $0,000. It will take many, many years to pay back. For a full-use system with generator, it will probably take $30,000 - $40,000 IF you don't use it for air conditioning. If you live in an area where you have a lot of cloudy days, it will take many, many, many, many years to pay back. The reason everyone isn't using solar power is because it is not cheap and has not been cost-effective for most situations. Most Americans would not like it's inconvenience at times. It is not new science. It is in use many places and well known. It is great for some applications and as fuel and electrical power cost increase it will be used more. Don't believe the media and hollywood. They are not interested in truth. They are just interested in making you believe their way. Study and learn.
- 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: How much energy can solar panels produce?
- The amount of energy solar panels can produce depends on various factors such as the size and efficiency of the panels, the location and climate, and the amount of sunlight available. On average, a typical residential solar panel system can generate anywhere from 4,000 to 8,000 kilowatt-hours (kWh) of electricity per year. However, larger commercial or utility-scale solar installations can produce significantly more energy, potentially reaching several megawatts of power.
- Q: Can solar panels be installed on flat roofs?
- Yes, solar panels can be installed on flat roofs. In fact, flat roofs are one of the common types of roofs where solar panels are installed. However, proper installation techniques and mounting systems are required to ensure optimal efficiency and safety.
