Solar Panels to generate electricity (photovoltaic)

Photovoltaic (PV) devices generate electricity directly from sunlight via an electronic process that occurs naturally in certain types of material, called semiconductors. Electrons in these materials are freed by solar energy and can be induced to travel through an electrical circuit, powering electrical devices or sending electricity to the grid.

PV devices can be used to power anything from small electronics such as calculators and road signs up to homes and large commercial businesses.

Solar energy is the cleanest, most abundant, renewable energy source available. Solar PV systems connected to the electricity grid, the PV system supplies electricity to the building and any daytime excess may be exported to the grid. Batteries are not required because the grid supplies any extra demand. However, to be independent of the grid supply, battery storage is needed to provide power at night. Today's technology allows us to capture this power in several ways giving the public and commercial entities flexible ways to employ both the heat and light of the sun

Holiday or vacation homes without access to the electricity grid can use solar systems more cost-effectively than if the grid was extended to reach the location. Remote homes in sunny locations can obtain reliable electricity to meet basic needs with a simple system comprising of a PV panel, a rechargeable battery to store the energy captured during daylight hours, a regulator (or charge controller), and the necessary wiring and switches. Such systems are often called solar home systems (SHS).

Solar PV systems are highly reliable and require little maintenance, they are ideal in distant or isolated places.

Solar PV are good almost for anything that require electricity power or energy from wrist watch to industrial building

Remote Applications

Remote buildings, such as schools, community halls, and clinics, can benefit from solar energy. In developing regions, central power plants can provide electricity to homes via a local wired network, or act as a battery charging station where members of the community can bring batteries to be recharged.

PV systems can be used to pump water in remote areas as part of a portable water supply system. Specialized solar water pumps are designed for submersible use or to float on open water. Large-scale desalination plants can also be PV powered using an array of PV modules with battery storage.

PV systems are sometimes best configured with a small diesel generator in order to meet heavy power requirements in off-grid locations. With a small diesel generator, the PV system does not have to be sized to cope with the worst sunlight conditions during the year. The diesel generator can provide back-up power that is minimized during the sunniest part of the year by the PV system. This keeps fuel and maintenance costs low.

Considering a Solar PV System

Da Pre Services will help you to  evaluate whether a small solar electric system will work for you, you should consider the following:

• Your available solar resource - do you have clear and unobstructed access to sunlight for most or all of the day, throughout the year?
• The system size - do you have a roof or area large enough to accommodate it?
• The economics - is it worth the investment?
• Local permits and covenants - are there any issues with installing a system?

Installing and Maintaining a Solar PV System

Proper installation and maintenance of your solar photovoltaic (PV) system is essential for maximizing its energy performance.

When we are installing a PV system, there are many factors that we will consider:

• Solar resource
• System sitting
• System size
• Type of system—grid –connected or stand – alone
• Electrical safety.

Therefore, it's best to have Da Pre Services install the solar panel system.
