Grid-tie systems

Solar electric systems are considered one of the most important sources of electricity for the 21st century. These systems can easily be placed in urban areas and attractively integrated into buildings. They are silent, produce no emissions, have no moving parts and require no fuel other than sunlight. They are modular, relatively easy to transport and install, and have very low maintenance requirements. Furthermore, with a grid connected solar electric system, it is not necessary to depend just on solar power. If the power generated by the solar panels were not enough to cover all you needs, you can obtain the rest from the electric utility.



Solar PV panels typically have a manufacturer’s warranty that guarantees power production for 20 years. However, many experts expect PV panels to work well for 30 years or longer. Unlike any other method of generating electricity, solar power systems have no moving parts. This translates into both, long life and very low system maintenance.

 

How it works: Solar panels collect the sun’s energy and convert it into direct current (DC) electricity. A solar inverter converts the DC electricity from the panels into the type of electricity we use at home: alternating current (AC). This electricity can be directly used for any application and will cost you nothing. If the panels do not generate enough power, the solar inverter is capable of extracting additional power from the grid.

This way you can progressively become more independent from conventional energy by expanding your solar installation when convenient. The use of a battery pack will allow you to create an uninterrupted power supply system (UPS).

Off-grid systems

What is off-grid? Living off-grid means having no connection to the electric utility. An off-grid house needs to generate 100% of the electricity by itself.


 

The reasons for living off grid are various:

* No possibility to connect to the grid.

* The connection to the grid may be too expensive (common in rural areas).

* The desire to be independent from utility companies.

 

Traditionally, the only option for such users was to generate their power with electric generators, but nowadays solar and wind energy have become an excellent alternative. Advantages of using solar energy. The generation of electricity through photovoltaic (PV) panels has become the most common option for domestic users.

The main advantages of using solar energy when compared with electric generators are:

* No noise

* No need for fuel

* Little to no maintenance required

* No CO2 emissions

* No power lines strung to your home

 

And of course, the knowledge that we are living in better harmony with nature and the idea of being completely independent from external energy resources are also a major consideration.




How it works

The required elements for a solar-powered off-grid system are:

* Photovoltaic panels (PV array)
These panels transform the incoming radiation into electricity. Under correct conditions, panels generate approximately 12V or 24V DC output. Depending on the connection.

* Battery bank
The periods when the panels generate more energy than you consume, the batteries will be used to store the excess energy.

* Charge controller
This element controls the charging current that goes into the batteries. It improves the charge of the batteries, increasing their lifespan.

* DC-AC Inverter
This electromechanical device converts direct current (DC) to alternating current (AC).

 

Solar Power Systems can design and install an off-grid solar power system you can rely on for decades.

Other applications

Solar powered pool filter pump
Solar Pool Pumping is one of the most cost-effective and logical uses of solar electricity. Using a few solar panels, panel mounting, and controller, the DC pool pump will have enough electricity to run all day using free, clean electricity from the sun. This is good news because swimming pools are usually an important load on your electric bill. The solar photovoltaic modules produce electricity which is used directly by a high-efficiency DC pump motor coupled to a standard swimming pool pump.

* The water filtering will be better because the DC pump runs slower than the usual AC pool pump.

* Summertime swimming season requires more pumping, and naturally, with more hours of sunlight, your pool pump puts in the work needed to keep your pool clean.





Solar air collectors - Home ventilation
The indoor climate in well insulated modern houses is normally adequate for your utilities bill but certainly not always good for your health. The problem stems from the lack of air renewal. The solution to these problems can be found in solar air collectors. These collectors send free, dry and warm air into the building – and are not connected to the main electricity supply (so there are no running costs).





Solar water pump
If you need water supplies beyond the reach of power lines, then solar power may solve the problem. Solar water pumps produce best during sunny weather, when the need for water is greatest. Solar water pumps are specially designed to utilize DC electric power from photovoltaic panels.
