1.5 billion people worldwide live without access to electricity. For people without access to an electrical grid, solar energy is the most cost-effective source of electricity as it provides clean energy to select regions and creates new opportunities.

While the start-up costs of solar equipment can be higher than generators, the long term operating costs are very small since there is no fuel to buy and little maintenance to carry out. One can consume solar energy or feed into a public power grid. With a battery storage excess generated electricity can be stored

What is Solar Power

Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photovoltaic effect. Photovoltaics were initially, and still are, used to power small and medium-sized applications, from the calculator powered by a single solar cell to off-grid homes powered by a photovoltaic array. They are an important and relatively inexpensive source of electrical energy where grid power is inconvenient, unreasonably expensive to connect, or simply unavailable. However, as the cost of solar electricity is falling, solar power is also increasingly being used even in grid-connected situations as a way to feed low-carbon energy into the grid.

Frequently Asked Questions

Can Solar Panels Charge in the Moonlight

Strictly speaking, solar panels depend on direct sunlight in order to produce electricity, so moonlight won’t charge them. Raw sunlight contains a number of energized particles, including the all-important photon. When photons from the sun strike one side of an array, they essentially cause electrons to break off from one panel, cross a thin membrane, and attach themselves to another panel. The crossing of the freed electrons is what generates a usable electrical current.
If there are no photons striking the panels, the electrons remain in place and no electricity is generated. This is why dark clouds or nightfall are so problematic when generating solar power on a commercially viable scale. When the sunlight disappears, so does the electricity. The electricity produced during daylight hours is not lost forever, however. The excess electricity is stored in large batteries and can provide power during overnight hours.
The main reason standard solar panels cannot charge in the moonlight is the nature of the moon’s light. Unlike the sun, the moon does not generate its own light energy. What people see on Earth is the sun’s light energy reflecting off the moon’s surface. A solar panel array placed on the moon would generate electricity during Earth’s nighttime hours because it is receiving direct sunlight containing photons. The reflected light seen from Earth does not contain a significant number of photons, so even a full moon could not cause the panels to generate electricity.
This is not to say that the power of the stars could not be used to generate electricity on Earth. A material sensitive to stellar energy, visible or invisible, could be used to create “stellar panels,” which could supplement solar cells by generating electricity at night or on cloudy days. The current limitations of such an alternative energy source are financial and technological in nature. A material capable of converting stellar energy into electricity has yet to be perfected, and the initial cost of building a usable array would be prohibitive.
There are reports claiming Russian scientists may have developed a proprietary material that could indeed convert stellar energy into electricity 24 hours a day. This so-called “heteroelectric” material is said to be less expensive to produce than standard solar cells, and has an efficiency rating of 90%, compared to the 10-12% efficiency rating of silicon-based solar panels currently in use. The research scientists who developed this material have largely avoided the public spotlight, however, and there are other scientists who have expressed doubts about this apparent energy breakthrough.

What is a residential solar electric system?
We offer comprehensive, code-compliant systems that allow you to generate your own electricity at home. Designed to interconnect with your existing utility service, they feature solar modules, plug-and-play wiring, power electronics and our patented mounting kits. Our installer network provides system installation and service.
How does a residential solar electric system work?
Solar cells in the modules mounted on your roof convert sunlight directly into DC power. A component called an inverter converts this DC power into AC power that can be used in your home. The system is interconnected with your utility. During the day, if your solar system produces more electricity than your home is using, your utility may allow net metering or the crediting of your utility account for the excess power generated being returned to the grid. Your utility would provide power as usual at night and during the day when your electricity demand exceeds that produced by your solar system. Systems are also available with a battery backup. Part of the power produced by your solar system during the day is used to charge the batteries, which provide power for your critical loads in the event of a power outage.
What happens during a power outage?
We offer two types of solar residential systems. One type of system powers your home during daylight hours but does not provide power in an outage, even on a sunny day. Another type of system powers your home during daylight hours but also has a battery backup designed to provide power to your home’s critical loads during an outage, day or night.
Does your solar system make hot water?
No. People often confuse our products with solar thermal panels that involve water circulating through tubes to be heated by the sun for swimming pool water heating. Our solar modules convert sunlight into electric current to operate appliances, motors, pumps and other devices.
What do the terms on-grid, grid-connected, grid-tied and off-grid mean?
On-grid, grid-connected or grid-tied means connected to the utility electrical grid. Our solar electric systems are designed as on-grid systems, meaning that they interconnect with your existing utility service. Off-grid refers to systems that are not connected to the utility electrical grid. Our solar electric systems can also be designed for a off-grid application(Stand alone system). That means it is not connected to a electrical grid at all. Our expert team will design your off-grid system for you!
How many solar panels do I need to produce enough electricity to run my house?
The array size you need depends on your average electrical usage, climate, roof angle, shading problems and many other factors. To approximate the array size you need, multiply your average daily electrical demand in kilowatt-hours by 0.25. The result is the approximate size of solar array, in kilowatts, needed to meet your electrical demand.
Will a system produce enough energy to cover all my electricity needs?
It is important to understand that a solar electric system does not need to provide all of the electricity you need to be of great value. A small system that displaces an average of one-quarter to one-half of your average demand reduces your electric bill. With battery backup, it can deliver uninterrupted power to critical loads during utility outages for days or weeks. We are happy to provide you with a system that supplies 100 percent of your energy needs, but cutting your electricity by 40 to 50 percent is typically the most cost-efficient approach for home solar power.
If I rent a home or apartment, can I still get a system?
No. Solar electric systems are available only to property owners. The installation of a solar electric system involves the property owner entering a contractual agreement that includes a potential property lien (called a mechanic’s lien).
How long will my solar power system last?
With no moving parts and made of very inert materials, our solar modules are tough. Most of the related system components should also last for many years without problems. The batteries in our residential system may need replacement in five to 10 years.
How can I tell how my system is performing?
We provide a power meter with the system. Located in your home, your power meter tells you exactly how much electricity you generate and use, and when you send power back to the utility grid. You will be able to manage your household usage like never before.
